Nature + Love Consultation: Construction Environmental Management Plan

Focus Consultants has been appointed by the Horniman Museum and Gardens to identify best practice procedures for managing the construction activities associated with the Nature + Love works.

Nature + Love project managers Focus Consultants are helping us consult with local residents of the Horniman, ahead of the site works due to take place starting later this year.

You can find details of the draft Construction Environmental Management Plan below.

Please respond with any comments or questions you have about this draft plan by 12 March 2024 to framework@horniman.ac.uk. We aim to respond to comments and questions within three weeks of the deadline. [Please note, this page is in the process of being updated following the consultation].


Construction Environmental Management Plan

Focus Consultants has been appointed by the Horniman Museum and Gardens to identify best practice procedures for managing the construction activities associated with the following works:

  • Contract 01: The refurbishment of The Natural History Gallery (NHG).
  • Contract 02: The creation of a Sustainable Gardening Zone (SGZ) and associated
    greenhouses with covered community space and an accessible toilet facility.
  • Contract 02: The creation of a Café and Ancillary Pavilion with toilet facilities and storage
    and Nature Explorers Adventure Zone (NEAZ).
  • Contract 02: The Nature Trail (NT).

These procedures will ensure that the interests of neighbouring residents, businesses, general public and the visitors are given special attention by the Contractor during the duration of the works.

This report identifies how the critical activities will be approached, and specifically covers the environmental, public health and safety aspects of the proposed development.

The baseline for our analysis is the Lewisham Good Practice Guide Control of Pollution and Noise from Demolition and Construction Sites (GPG). We have viewed those requirements as the minimum standards to be achieved.

This document details the specific obligations on the Contractors when undertaking the works and the control measures to be employed for each environmental issue.

Nature of the Project/scope of works

The Natural History Gallery

  • Careful removal of a few exhibition cases and upgrading of the remaining majority.
  • Removal of existing ventilation, heating plant and equipment, replacing current ventilation with high level ventilation duct runs, and the creation of low-profile discreet ventilation louvre on underside of beam.
  • Renovation of existing timber window and incorporation of new bespoke ventilation louvre.
  • New handrail extension and associated structural support to first floor balustrade.
  • Refurbishment, repair, and redecoration of all surface finishes.
  • Removal of all roof coverings and reinstating with a lightweight insulated system, including the removal, renovation and re-installing the existing lanterns.
  • The lowering of the external ground level along the external wall to be at least 150mm lower than any DPC that might be present.

Sustainable Gardening Zone

Provide propagation facilities that are modern and fit for purpose – automatic venting and heating using either a sustainable biomass boiler or air source heat pump and rain harvesting technology.

  • The removal of existing poly tunnels and glasshouses and replacing with one single glasshouse freeing up more room for an uncovered hard standing area for plants.
  • A glasshouse with water and heating, to be maintained with different climatic conditions when required including a potting area where staff can pot-on plants, store tools and materials safely. It can also be used to overwinter bulbs and tubers.
  • Construction outdoor learning area focusing on sustainable gardening techniques. This covered space must also be used for community activities, with an accessible toilet and washing area.
  • Major landscaping works to incorporate viewing area, improve accessibility to the South Downs, improve the horticultural offer, provide a community growing area, create winter plant interest using coloured stems, winter flowers, structural evergreen shrubs and trees and winter bulb display and the community growing area.
  • Improving the water supply system. Only having one water point outside the zone, it is necessary to have at least two water points in different locations within the area. Capture rainwater from the roof of at least one of the buildings in the zone.

Nature Explorers Adventure Zone

  • The construction of a cafe within the footprint of the Old Boating Pond to provide a food and drink offering that will only be open during daylight hours, with outside in-situ seating that will not be required to be stored away every evening.
  • There will also be picnic tables around the café and the play space that families can use to eat at with bark/ wood chippings/Breedon gravel underneath.
  • The existing path will be upgraded to enable vehicles to reach the café for deliveries and maintenance.
  • There will also be an Ancillary Block to provide toilet and baby change facilities.
  • Major landscaping to provide a new Nature Explorers Adventure Zone.

The Nature Trail

  • Construction of new access from the gardens across the “Night Walk” to a new accessible ramped access to the Nature Trail. It should be noted that the Night Walk is a public footpath outside the curtilage of the Horniman Gardens.
  • Construction of retaining walls.
  • Changes to the route of the pathway, localised path widening.
  • Additional bench seating and interpretation.
  • Erection of a new storage shed.

The Construction Site

This section sets out procedures that should be implemented during site operations relating to site management practices

Working Hours

  • Lewisham’s GPG states Site Working Hours will be:
    • Monday to Friday: 8am – 6pm
    • Saturday: 8am to 1pm but not significantly noisy work which will impact on neighbouring properties.*
    • Sunday and Bank Holidays: No work where noise audible at site boundary.
  • The Horniman’s Gardens are open to the public as follows:
    • Monday to Saturday gates open at 7:15 am.
    • Sunday and Bank Holidays gates open at 8:00 am
  • The Gardens close at the following times in 2023:
    • Monday 5 February – Sunday 3 March: 5.30pm

    • Sunday 27 October – Sunday 2 February 2024: 4.20pm

Public opening hours are expected to be similar in 2024.

All vehicles and plant arriving at and leaving the site should comply with the same restrictions on hours. The main contractor should be held responsible for ensuring these instructions are given to all drivers, including those delivering site materials.

Any deviation from these hours will require prior approval from the Lewisham Environmental Protection Team.

Good Housekeeping

The Contractor will follow a ‘good housekeeping’ policy at all times. This will include, but not necessarily be limited to the following. The Contractor will:

  • Ensure considerate site behaviour of the Contractor’s staff.
  • Ensure the noise from lorry reversing alarms are kept to minimum levels.
  • Prohibit open fires.
  • Ensure that appropriate provisions for dust control and road cleanliness are implemented, to both the adjoining residential roads on the Horniman’s Gardens estate roads.
  • Remove rubbish at frequent intervals, leaving the site clean and tidy.
  • Frequently inspect, repair and re-paint as necessary all site hoardings to comply with the conditions of the Lewisham’s GPG section 9.11 and any relevant Licence. – all flyposting and graffiti are to be removed as soon as reasonably practicable and within 24 hours of its appearance.
  • Maintain toilet facilities and other welfare facilities for its staff.
  • Remove food waste.
  • Prevent vermin and other infestations; and undertake all loading and unloading of vehicles as identified on the logistics drawings.

Community Liaison

Lewisham Council considers that liaison with local residents who may be affected by construction works is essential and this is set out with GPG section 2.2 Community Liaison and Complaint Resolution. The Contractor will arrange a public meeting to provide information about the further coming works prior to starting on site. This will include information about traffic management, pedestrian movement, waste management, dust management etc. We are not anticipating any flood lighting or drive piling to be required but if they are, the Contractor should notify local residents in advance of these items being
carried out.

If flood lighting is required it must be set up so as not to be directed into the windows of residential properties.*

Communication to local residents should include publicity, including the name and telephone number of a main contact which should also be displayed on the site hoardings. This contact person should be able to give further information to the caller and deal with any complaints or emergencies that may arise at any time. A copy of the letter to be sent to residents along with the planned distribution list should be included with the return form in Appendix 1 of the GPG and sent to Lewisham’s Environmental Protection Team at least 28 days before the start of works.

Complaints should be reported to Lewisham’s Environmental Protection Team within 24 hours by telephone and/or email, investigated and where appropriate measurements taken and where necessary mitigation methods implemented, or work practices modified.

The results of the investigation, along with details of any mitigation methods implemented or work practice that has been modified and how complainants have been kept informed should also be sent to Lewisham’s Environmental Protection Team as soon as possible.

All site staff are to be regularly briefed regarding the complaint procedure.

Security

  • The Contractor is to ensure that each individual site, the site compound and any satellite storage compounds are secure and prevent unauthorised entry to all areas.
  • Site gates will be closed and locked when there is no site presence. Alarms will incorporate an appropriate cut-out period.
  • Access and egress will be via manned security gates.

Hoardings, Site Layout and Facilities

  • Each individual site will be completely secure to deter public access.
  • The proposed hoarding line and gates, all of which will be in accordance with the GPG, are shown on the enclosed plans.
  • Site welfare arrangements are expected to be located within easy reach of each individual site area.

Emergency Planning and Response

The Contractor will develop a plan for emergencies to incorporate:

  • Site specific risk assessment.
  • Ensure appropriate site induction for all contractor teams to include information around pollution control and reporting procedure.
  • Emergency procedures including emergency pollution control to enable a quick response.
  • Emergency phone numbers and the method of notifying Lewisham and statutory authorities. Contact numbers for the key staff of the Contractor will also be included.
  • The Contractor will display a ‘contact board’ on the hoarding identifying key personnel with contact addresses and telephone numbers, so that members of the public know who to contact in the event of a report or query.
  • London Fire and Emergency Planning Authority (LFEPA) requirements for the provision of site access points.
  • Site Fire plan and management controls to prevent fires.
  • A plan to reduce fire risk and potential fire load during construction, operation and subsequently during maintenance or repair. The project will comply with any third-party requirements as may be appropriate at specific sites.
  • A plan to respond to a pollution incident on site, including details of reporting to client and relevant authorities

Hoists

  • To deliver materials to the roof of NHG will be via an external hoist positioned on a pavement gantry.
  • A small mobile hydraulic crane is expected to be in operation at the site of the Boating Pond (café and play area).

Considerate Constructors Scheme

  • The site is to be registered with the ‘Considerate Constructors Scheme’ and the ‘Freight Operator Recognition Scheme’.
  • These schemes ensures that contractors carry out their operations in a safe and considerate manner with due regard to neighbours, passing pedestrians and road users.
  • Traffic Marshalls/Banksmen will monitor incoming vehicles and will marshal construction vehicles and materials as they move around the site.
  • Safe pedestrian routes will be clearly marked, and construction vehicles and materials will be escorted to avoid obstructing these routes.
  • The local community will be engaged with and access to information relating to the construction will be made available.
  • Carbon will be minimised throughout the supply chain.
  • The Code of Considerate Practice will be adhered to: The Code of Considerate Practice – Considerate Constructors Scheme (ccscheme.org.uk)

Site Logistics

The Traffic Management Plan (TMP) is included at Appendix C of this document. Please note that as there will be two contractors on site at the same time, this TMP will apply to each of them. The Natural History Gallery Contractor will take overall responsibility for managing and coordinating site deliveries and providing related facilities such as vehicle wash.*

Lewisham recommends that a Construction Logistics Plan (CLP) is submitted for their review, this is also an essential document that will be vital to the success of the project.*

The CLP provides the key logistics strategy for the project and ensures that the products and materials arrive on site at the time and in the quantities that are required.*

Feilden Fowles’ draft drawings NLP-FF-00-XX-DR-A-00119 – Proposed Construction Management Site Plan illustrate the proposed overall logistics plan for the site (see below in Appendix A), which incorporates the following key features:

All construction and delivery vehicles with a gross weight of 3.5 tonnes or more (Heavy Good Vehicles) shall be required to enter and leave the site via the London Road (A205) main entrance gate. Light good vehicles may use either the London Road gate or Horniman Drive gate, subject to the restrictions set out in this plan, concerning hours of use and adherence to the approved route.

All large deliveries via London Road between 6am – 9am and 2pm – 3pm.

Smaller deliveries via Horniman Drive between 9:30am – 11am.

  • All construction and delivery vehicles shall be required to enter and leave the site via the London Road (A205) main entrance gate.*
  • All deliveries in relation to the project via London Road between 6:00am – 9:00am and 2:00pm – 3:00pm.*
  • Occasional overnight deliveries may be required to avoid visitors and heavy traffic, to be discussed and agreed with the Horniman and Local Authority. Overnight deliveries would have to be made via the London Road entrance.
  • Vehicle access to Michael Horniman Building to be retained throughout.
  • Grass bank area behind the Michael Horniman Building’s (MHB) North Hall fire exit is earmarked for Contractor’s compound for Contract 1.
  • Various areas are identified as Contractor’s compound for Contract 2.
  • Location of temporary footpath for Horniman and Contractor staff identified.
  • Location of MHB existing fire escape route identified and must be retained throughout.
  • Tree Route Protection areas will be reviewed and, where necessary and possible, the widening of paths will be considered to ensure ecology is protected.
  • Access for event hires in the Conservatory Building are to be maintained, including areas for temporary marquees and deliveries.
  • Blue Badge Parking Spaces will be maintained, and the Contractor will ensure access to the three spaces is not hindered by works on site.

The Contractor is to take onboard the draft Proposed Construction Management Site Plan and all other relevant information any fully develop the CLP.

Traffic Management

This section highlights the measures the Contractor may adopt to avoid nuisance to the public that may arise from increases in traffic flows.

All construction and delivery vehicles related to the construction works for Nature + Love shall be required to enter and leave the site via the London Road (A205) main entrance gate. There are expected to be up to twenty deliveries per week in relation to the construction works (approx. 10 per Contract).*

All construction and delivery vehicles with a gross weight of 3.5 tonnes or more (Heavy Good Vehicles) shall be required to enter and leave the site via the London Road (A205) main entrance gate. Light good vehicles may use either the London Road gate or Horniman Drive gate, subject to the restrictions set out in this plan, concerning hours of use and adherence to the approved route.

There are expected to be up to twenty deliveries per week in relation to the construction works.

The GPG states that all vehicles and plant arriving at and leaving the site should comply with the same restrictions on hours. The main contractor will be held responsible for ensuring these instructions are given to all drivers, including those delivering site materials and coordinating between different suppliers when there are multiple deliveries in the same time period. There will be wheel/ chassis wash facilities at the entrance to the site suitable for the size and type of vehicles.

The Natural History Gallery Contractor will be responsible for the provision of these facilities along with Traffic Marshalls and overall management of the deliveries.*

All smaller vehicles which are making deliveries via Horniman Gardens will be restricted to use A205, Honor Oak Road and Westwood Park to access Horniman Gardens, to stop unsuitable traffic using residential roads in the area.

Prior to commencement of works, a meeting will be held with the Horniman site management team (including Security and Estates) to agree delivery arrangements. This will ensure priority access is given to the Horniman deliveries (estimates of 10 per day).

Arrangements for delivery, unloading, disposal of waste etc. requires careful planning and programming, deliveries must be arranged with the Site Manager or their nominee to enable co-ordination. Traffic Marshalls will be provided to control site deliveries for both arrival and departure of all delivery vehicles, plant and materials being moved around site. Strict controls will be enforced; Contractors must give 48 hrs /2 working days’ notice of deliveries and/or collections. Vehicles arriving out of sequence will be turned away. Special loads will possibly require several weeks’ notice pending Horniman and Local Authority approvals.

The Contractor will endeavour to ensure that all heavy vehicle traffic is limited to times outside of rush hour, Monday to Friday. Construction vehicle movement will also be carefully planned and coordinated to avoid the AM and PM school drop off and collections. This will reduce congestion and safeguard pedestrians.

Safety of cyclists is of paramount importance and all vehicles entering and exiting the site will fully comply with CLOCS, the requirement for vehicular safety equipment. Deliveries will abide by London standards recommended by the Construction Industry Cycling commissioning manifesto. (To note, as per the Horniman policy, no cycling is permitted around the grounds and cyclists must dismount and use the cycle parking provided.)

As the London Road entrance is also used by some pedestrians, there will be pedestrian management at this point and Traffic Marshalls will direct any vehicles or materials moving through the Gardens. A traffic management system will be put in place to ensure the safe turning of vehicles into and out of the London Road entrance.

There may be specific need to work outside of the hours set out in 4.1 to manage certain noisy works and deliveries to limit impact on the calendar of public events. In these circumstances the contractor will liaise with all parties, including Lewisham and TfL as applicable.

Indicative types of on-road vehicles arriving and departing the site are as follows:

Via London Road:
9.11m (6) wheeled rigid “muck-away lorry
8.73m (6) wheeled rigid ready mix concrete lorry
7.90m (4) wheeled skip lorry

Via Horniman Drive:
6.65m (4) wheeled rigid small Flat bed with Hiab delivery lorry
5.2m (4) wheeled general delivery van

  • 9.11m (6) wheeled rigid “muck-away” lorry
  • 8.73m (6) wheeled rigid ready mix concrete lorry
  • 7.90m (4) wheeled skip lorry
  • 6.65m (4) wheeled rigid small Flat bed with Hiab delivery lorry
  • 5.2 m (4) wheeled general delivery van.*

All on-road vehicles will comply with the Ultra Low Emission Zone (ULEZ) vehicle emission standards as a minimum. Evidence that contractors and suppliers have been contacted and their responses to the applicant in respect to the use of ULEZ compliant vehicle a ULEZ vehicle compliance form for the construction works will be issued to the London Borough of Lewisham Council monthly by e-mail. The use of Ultra-Low Emission Vehicles (ULEV) (e.g., Electric, Hybrid (Electric-Petrol) where possible will be encouraged at the procurement stage of the tender for these services.

The Contractor will actively work with suppliers that can provide electric or hybrid vehicles. Subcontractors will be required to comply with the emission hierarchy where practicable. A software platform will be used to monitor the carbon footprint of deliveries, tracking the start, finish location and means of transportation. The ULEZ vehicle emissions compliance will be monitored monthly log sheet.

Indicative Non-Road mobile machinery (NRMM) types for site use as follows:

  • Telehandler-Material distribution
  • Mini Excavator-Earthworks
  • Dumper-Earthworks
  • Spider crane-Lifting

All deliveries to site will be undertaken with full regard paid to:

  • Reduction and control of plant movements
  • All vehicles to be directed by a competent person
  • Pedestrian and vehicle directional signage – suitable barriers will be erected to prevent pedestrian crossing the site entrances when deliveries are taking place.
  • Mobile plant will only be operated by a competent person with a bank’s person in attendance to any movements

All non-road mobile machinery (NRMM) will comply with Stage IV Emission Standards (or the latest standard if the GLA requirements change) as a minimum if equal to or over 37kW. Where compliance with Stage IV requirements is not achievable or practical, an exemption will be sought from the GLA prior to arrival of the equipment on site.

There is no parking available on site for contractor vehicles and parking in local streets is very limited, all contractors and sub-contractors’ operatives should be encouraged to use public transport wherever possible.

Site Waste Management

The Contractor will carry out the works in such a way that, as far as is reasonably practicable, the amount of spoil and waste (including groundwater, production water and run-off) to be disposed of is minimised, and that any waste arising from the site is properly categorised and dealt with in accordance with the appropriate legislation and guidance. Opportunities for re-using or recycling construction or demolition waste should be explored and
implemented.

A formal and detailed Waste Management Plan will be prepared by both* Contractors*. The disposal of all waste or other materials removed from the Site will be in accordance with the requirements of the Environment Agency, Control of Pollution Act (COPA), 1974, Environment Act 1995, Special Waste Regulations 1996, Duty of Care Regulations 1991 and the Waste Management Regulations 2006.

Waste should be stored away from boundaries where possible, and carefully managed not to cause harm or nuisance to neighbouring properties.

This approach complies with the waste hierarchy whereby the intention is first to minimise, then to treat at source or compact and, finally, to dispose of off-site as necessary. All relevant Contractors will be required to investigate opportunities to minimise and reduce waste generation, such as:

  • Agreements with material suppliers to reduce the amount of packaging or to participate in a packaging take-back scheme.
  • Implementation of a ‘just-in-time’ material delivery system to avoid materials being stockpiled, which increases the risk of their damage and disposal as waste.
  • Attention to material quantity requirements to avoid over-ordering and generation of waste materials.
  • Re-use of materials wherever feasible (e.g. re-use of crushed concrete from demolition process for fill; re-use of excavated soil for landscaping; re-use of internal equipment and plant from existing buildings). Concrete will be taken off the site for crushing and re-use.
  • The Government has set broad targets of the use of reclaimed aggregate, and in keeping with best practice, Contractors will be required to maximise the proportion of materials recycled.
  • Segregation of waste at source where practical. Where on site waste segregation is not practical it will be segregated off site by the Contractor.
  • Re-use and recycling of materials off-site where re-use on-site is not practical (e.g., through use of an off-site waste segregation facility and re-sale for direct re-use or reprocessing). Our expectations in this regard are shown below.
  • Architectural salvage – 100% re-used – several architectural salvage companies in London
  • Structural steel for re-use – 100% re-used – any complete sections salvaged during the demolition works will be retained by the Contractor for re use in temporary works or recycled as scrap metal.
  • Metals – 100% recycled – Every effort will be made to recycle these materials on site with any surplus being taken to waste transfer station.
  • Hardcore (brick/block/concrete etc.) – 100% recycled – Taken off-site to be crushed and reused
  • Excavated material/clay etc. – 100% recycled – Clay – 100% processed for re-use as fill material (subject to analysis).
  • Timber – up to 80% re-used. The amount re-used will depend on the material – we will attempt to salvage any re-useable timber for hoardings, battening, shuttering etc. for possible use on site with the balance being retained by the Contractor
  • Glass (non-tempered, non-laminated and nonbomb proofing film etc.) – 100% recycled – Processing facility in Greenwich & Park Royal.
  • Mixed waste – the amount recycled will depend on the material – An absolute minimum will remain for transport to landfill.
  • Asbestos – 100% landfill – Taken to a licensed site.

Overall, the waste management for the site is likely to comprise of the following:

  • Waste arising from stripping out, demolition and minor excavations will be removed from site by wheelie bin to waste lorries and taken to an off-site waste management centre for segregation and recycling.
  • Packaging will be minimised and where possible removed from site on the same delivery vehicle that brought it to site.
  • General waste will be removed from site by wheelie bin to a waste lorry daily. Waste material will not be allowed to be retained on site. Ideally the contractor will operate an evening back shift for removal of rubbish each day.

Noise and Vibration

The Horniman and the Contractor will agree a baseline for which the Contractor will monitor and control levels of noise and vibration from the site.

Lewisham’s GPG section 3 set out their requirements for the control of Noise and Vibration.

Noise control

The Contractor’s environmental team will undertake a noise assessment using noise predicting software which projects noise levels at adjoining properties based on the emissions made by specific plant. This noise assessment will be carried out in accordance with BS5228-1 2009 ‘Code of Practice for noise and vibration on construction and open sites and is above the requirements of the GPG.

This assessment allows the Contractor to select the most appropriate plant, methodology and controls to minimise disruptions of buildings at close proximity of the adjacent structures (sensitive receptors) and in particular live and occupied premises during the demolition and alteration phases.

Noise levels will be monitored by the Contractor during the course of the demolition and construction works. Lewisham shall be given access to all noise readings if required as soon as they become available.

Although the noise levels to be included in a formal agreement between the Contractor and Lewisham are the maximum to be allowed, at sensitive locations the  Contractor will be requested to achieve, where practicable, noise levels lower than the specified limits.

Site operatives must be conscious of raised voices when arriving, leaving and whilst on site to minimize impact on local amenity.*

Noise Control Provisions – Screens and Scaffolds

The Site Manager will notify the Client of any planned noisy works in the regular logistics meeting.

Where hard demolition occurs inside the Natural History Gallery*, breaking out will be undertaken by handheld tools. Working hours will be managed to suit the operations of the Horniman and the working operations of neighbours as far as possible. This might mean undertaking noisy works between 8am and 10am, followed by a quiet period of clearing away.

Physical barriers will be deployed where possible to contain noisy operations within the working area as far as possible. Structural born noise will be monitored, and times of work managed to limit disruption to others.

Vibration Control

The Site Manager will notify the Client of any planned works that may result in vibration in the regular logistics meeting.

Vibration is a particular risk during structural breaking out in close proximity to heritage finishes. The measures taken to reduce the acoustics of these operations will also assist in mitigating the effects of vibration on the existing building and neighbours.

The Contractor will comply with the vibration levels established by agreement with Lewisham.

Equipment is to be selected giving consideration to noise and vibration. Where noise is unavoidable noise assessments are to be made and, if necessary, hearing protection zones established. Consideration will be given to the neighbours with consultations.

Operatives who are required to use vibrating equipment must be made aware of the health risks associated and their exposure must be monitored and recorded.

In areas where vibration is a risk to Museum objects, vibration sensors will be utilised to monitor vibration and alert the Contractor if maximum levels are exceeded so that works can ceased.

Works which may course high levels of vibration near residential properties e.g. construction of foundations for the café, should not take place on Saturday mornings but be restricted to Monday-Friday, 8am – 6pm.*

Air Quality and Dust Minimisation

The Contractor will, as far as reasonably practical, seek to control and limit emissions to the atmosphere in terms of gaseous and particulate pollutants from vehicles and plant used on site and dust from construction activities.

Lewisham’s GPG section 4 set out their requirements for the control of Dust and Air Pollution.

Throughout the project the Contractor will ensure the following:

  • There is no burning of waste materials on site.
  • There is an adequate water supply on the site.
  • Disposal of run-off water from dust suppression activities and is in accordance with the appropriate legal requirements.
  • A Dust Management Strategy will be implemented.
  • All dust control equipment is maintained in good condition and record maintenance activities.
  • Where creation of dust is unavoidable personnel must use appropriate RPE. N.B. RPE will often be required when wet cutting stone or concrete. Stringent control measures must eliminate, minimise nuisance factor to the general public in accordance with environmental requirements.
  • Consideration must be given to the use of vacuum attachments to tools used in operations that will produce dust e.g. circular saw on insulation/plasterboard. The decision not to use such attachments must be justified within the risk assessment. Damping down is an alternative control method if dust capture/containment is not reasonable.
  • Site hoarding, barriers and scaffolding are kept clean.
  • Loading of material into lorries within designated loading areas.
  • If necessary, clean public roads and access routes using wet sweeping methods.
  • Vehicles held on site for any reason have exhausts positioned such that the risk of resuspension of ground dust is minimised.
  • All vehicles carrying loose or potentially dusty material to or from the site are fully sheeted.
  • Minimise the amount of waste material held on site.
  • Sheet, seal or damp down unavoidable stockpiles and skips of excavated material held on site, where required.
  • Avoid double handling of material wherever reasonably practicable.
  • Ensure water suppression is used during demolition operations.
  • Use enclosed rubble chutes and conveyors where reasonably practicable or use water to suppress dust emissions from such equipment.
  • Sheet or otherwise enclose loaded bins and skips.
  • Minimise drop heights from conveyors, loading shovels, hoppers and other loading or handling equipment and use fine water sprays on such equipment wherever appropriate.
  • Use prefabrication of goods and materials to reduce the need for grinding, sawing and cutting on site wherever reasonably practicable.
  • Only use cutting, grinding or sawing equipment fitted or in conjunction with suitable dust suppression techniques such as water sprays or local extraction.
  • The engines of all vehicles and plant on site are not left running unnecessarily to prevent exhaust.
  • Use low emission vehicles and plant fitted with catalysts, diesel particulate filters or similar devices.
  • Use ultra-low sulphur fuels in plant and vehicles.
  • That plant will be well maintained, with routine servicing of plant and vehicles. On site servicing and maintenance to be carried out where possible.
  • That all project vehicles, including off-road vehicles, hold current MOT certificates where required.
  • Carry out site inspections regularly to monitor compliance with dust control procedures set out above and record the results of the inspections, including nil returns, in the log book detailed.
  • Increase the frequency of site inspections when activities with a high potential to produce dust are being carried out and during prolonged dry or windy conditions.
  • Record any exceptional incidents causing dust episodes on or off the site and the action taken to resolve the situation in the log book detailed in above.

The Contractor will ensure that dust monitoring will be carried out during potential dust producing activities. The assessment will look at the dust raising potential of demolition and construction activities proximity to potential receptors and the duration of construction activities at each location.

Further information about this is provided in Appendix D.*

Protection of Historic Fabric

The Contractor will properly safeguard all buildings, structures, works, services or installations from harm, disturbance or deterioration during the construction period.

This will be achieved by providing the necessary support and protection that the existing fabric requires.

Prior to commencing any demolition and alterations works, the Contractor will prepare a schedule of buildings, structures and services within the zone of influence of the proposed works.

To comply with the above requirements, it will be necessary to ensure the following procedures are established:

  • Existing fabric must be accurately surveyed and assessed to ensure that the proposed works are technically feasible.
  • Works to be undertaken by suitably qualified specialist Contractors using skilled and experienced operatives.
  • Careful monitoring of fabric as works proceeds.
  • Ensure any retained structure is fully protected during the construction process to prevent environmental or accidental damage.
  • Specialist Contractor to prepare detailed method statement for agreement with all third parties prior to works commencing.
  • Submit permit to work procedure to be established between all interested parties.

Managing the Environmental Impact of Construction

This section sets out the requirements on the Contractor for managing the environmental impacts of constructing the development.

The Contractor must demonstrate in detail how the requirements of the GPG will be met.

The Contractor will need to demonstrate the management, monitoring, auditing and training procedures that are in place to ensure compliance with the GPG. The contractor will set out the specific roles and responsibilities of their personnel in managing, monitoring all of the works, including any sub-contractors.

The specific measures to be implemented by the Contractor will include:

  • The Contractor will liaise with Lewisham’s Environmental Protection Team on a regular basis, agreeing routine arrangements for each site’s activities and ensuring compliance with the GPG.

Appendix C

Traffic Management

Prior to commencement, a meeting will be held with the highways department of London Borough Lewisham to discuss and agree the proposed traffic management plan and logistic plan.

In preparing this section of the Traffic Management Plan (TMP) we have taken into consideration the following guidance
documents:

  • London Borough of Lewisham Good Practice Guide
  • TFL Construction Logistic Planning Guidance
  • Construction Logistics and Community Safety (CLOCS) guidance

Prior to commencement of the works a meeting will be held with the Horniman Museum site management team to agree delivery arrangements. This is to ensure priory access is given to the Horniman Estate deliveries (estimate 10 per
day).

There will be careful planning and programming of deliveries and strict control will be enforced. 48 hours’ notice (two working days) must be give for deliveries and /or collections. Vehicles arriving out of sequence will be turned away.

Special loads may require several weeks’ notice pending Horniman Estate and Local Authority approval.

The contractor will endeavor to ensure that all heavy vehicle traffic is limited to times outside of rush hour, Monday to Friday. Construction vehicle movement will also be carefully planned and coordinated to avoid the AM and PM school drop off and collections. This will reduce congestion and safeguard pedestrians.

To ensure all contractors, delivery companies and visitors are aware of the traffic routes and restrictions, several methods will be implemented. This will include written briefings sent to delivery companies at the time of the orders being placed and verbal briefings within the site induction to all contractors and visitors to site.

Safety of cyclists is of paramount importance and all vehicles entering and exiting the site will fully comply with CLOCS, the requirement for vehicular safety equipment. Deliveries will abide by London standards recommended by the Construction Industry Cycling commissioning manifesto.

Traffic Marshal(s) will be provided to control site deliveries for both arrival and departure of all delivery vehicles. All delivery companies will be or encouraged to become members of FORS in accordance with the Tfl Construction Logistics Planning guidance for deliveries in London.

The Traffic Marshals will be fully qualified (Site Access Traffic Marshal qualification as a minimum) and will be always on duty during loading and off-loading activities to ensure that vehicles and pedestrians passing the site entrances do so in a safe manner.

All vehicles will enter the site in a forward direction and exit in a forward position. No reversing will be allowed onto the public highways. Vehicles will not be permitted to stack up. The construction vehicles will not block London Road or Horniman Drive.

Large deliveries and vehicles access will be made via the London Road gated entrance and access roads as shown on drawing NLP-FF-00-XX-DR-A-00119 shown above.

Smaller deliveries will be made via Horniman Drive entrance. All deliveries via Horniman Drive will be between 9-10am to avoid any disruption to residential areas.

At both London Road and Horniman entrances used by pedestrians there will be pedestrian management provided by the Traffic Marshals. All contractors site deliveries will be escorted through the site to ensure safe transit of the deliveries and a bankman will supervise any off-loading operations.

Indicative types of on-road vehicles arriving and departing the site are as follows:

  • 9.11m (6) wheeled rigid “muck-away” lorry
  • 6.65m (4) wheeled rigid small Flat bed with Hiab delivery lorry
  • 5.2 m (4) wheeled general delivery van
  • 8.73m (6) wheeled rigid ready mix concrete lorry
  • 7.90m (4) wheeled skip lorry

See Indicative on-road vehicle data Appendix A.

All on road vehicles will comply with the Ultra Low Emission Zone (ULEZ) vehicle emission standards as a minimum. Evidence that contractors and suppliers have been contacted and their responses to the applicant in respect to the use of ULEZ compliant vehicle a ULEZ vehicle compliance form for the construction works will be issued to the London Borough of Lewisham Council monthly by e-mail. The use of Ultra-Low Emission Vehicles (ULEV) (e.g., Electric, Hybrid (Electric-Petrol) where possible will be encouraged at the procurement stage of the tender for these services.

The contractor will actively work with suppliers that can provide electric or hybrid vehicles. Subcontractors will be required to comply with the emission hierarchy where practicable. A software platform will be used to monitor the carbon footprint of deliveries, tracking the start, finish location and means of transportation. The ULEZ vehicle emissions compliance will be monitored monthly log sheet (See Appendix C).

All deliveries to site will be undertaken with full regard paid to:

  • Reduction and control of plant movements
  • All vehicles to be directed by a competent person
  • Pedestrian and vehicle directional signage – suitable barriers will be erected to prevent pedestrian crossing the site entrances when deliveries are taking place.
  • Mobile plant will only be operated by a competent person with a bank’s person in attendance to any movements.

Consultation with the local authority of the London Borough of Lewisham will continue throughout the project to
ensure:

  • Construction methods minimise the potential impact on nearby residents. These include liaison with the residents on a regular basis and coordinate work to minimise disruption to residents, use of low emissions site plant equipment, limiting the amount of traffic movement to and from the site. Keeping dust and noise to a minimum by using noise and dust control measure (See AQDM plan).
  • Maintenance of the existing public highway by using both London Road and Horniman Drive entrances. If one access route was to become blocked or unusable for third party reasons there is always a second access available.
  • Segregation of all pedestrians, public or employees, on or in the vicinity of the site through the use of safe access routes and employment of Traffic Marshals.

Indicative Non-Road mobile machinery (NRMM) types for site use as follows:

  • Telehandler-Material distribution
  • Mini Excavator-Earthworks
  • Dumper-Earthworks
  • Spider crane-Lifting

See Indicative (NRMM) data Appendix B.

All non-road mobile machinery (NRMM) will comply with Stage IV Emission Standards (or the latest standard if the GLA requirements change) as a minimum if equal to or over 37kW. Where compliance with Stage IV requirements is not achievable or practical, an exemption will be sought from the GLA prior to arrival of the equipment on site.

The contractor will actively work with suppliers that can provide electric or hybrid vehicles. Subcontractors will be required to comply with the emission hierarchy where practicable.

The NRMM emissions compliance form will be monitored monthly (See Appendix D)

A – Indicative Plant Data sheets – Road Examples

Note: All suppliers will apply the emissions hierarchy relating to on-road Ultra Low Emissions Zone (ULEZ) compliant vehicles namely (1) Electric; (2) Hybrid (Electric-Petrol); (3) Petrol; (4) Hybrid; (Electric-Diesel) Diesel; (Euro 6 and Euro VI)

Air Quality Dust Management Plan

Air Quality Statement

The Horniman/Contractor is committed to applying the Air Quality Management standards required by Section 11 of the Planning Guidance Supplementary Planning document (London Borough of Lewisham) and confirm that we shall apply the relevant air quality control mitigation measures outlined in The Control of Dust and Emissions During Construction and Demolition Supplementary Planning Guidance document, produced by the Mayor of London and dated July 2014.

These are more fully described later in this Air Quality Dust Management Plan.

Introduction

Background

The purpose of the Air Quality Dust Management Plan (AQDMP) is to outline our approach to managing the construction impacts from dust and air pollutant emissions at the building project at the, in accordance with Planning Approval DC/23/130987 Condition 3 which states the following:

  • Prior to the commencement of development hereby approved, a Dust Management Plan (DMP), based on an AQDRA (Air Quality and Dust Risk Assessment), shall be submitted to and approved, in writing, by the local planning authority. The DMP shall be in accordance with The Control of Dust and Emissions during Construction and Demolition SPG 2014. The DMP will need to detail the measures to reduce the impacts during the construction phase. The development shall be undertaken in accordance with the approved plan.
  • Reason: To manage and prevent further deterioration of existing low-quality air across London in accordance with London Plan Policy SI 1 ‘Improving air quality’ and Policy T7 ‘Deliveries, servicing and construction’ of the London Plan (March 2021), and paragraph 181 of the NPPF.
  • Approved details shall be fully implemented and permanently retained and maintained during the construction phases of the development. To comply with the requirements of the NPPF (2019), Policies 7.14a-c of the London Plan (2016) and policy CC10 of the Local Plan (2018)”

This document includes our Air Quality (Dust) Risk Assessment, inventory and timetable of dust generating activities, dust emission control methods to be employed, dust monitoring, Non-Road Mobile Machinery (NRMM), Ultra Low Emission Zone (ULEZ) vehicles, complaints and incident procedures.

During construction, site activities will have the potential to affect local air quality from dust deposition and increases in particulate matter concentration. Mitigation measures will be implemented to ensure that any impact on local air quality is minimised.

The agreed contents of this AQDMP will form part of the development plan, it is a Planning obligation requiring discharge by the London Borough of Lewisham (LBL) prior to commencement of work. The Plan will be regularly reviewed and any changes and/or improvements will be developed, added and agreed with the Council. The Plan will be revised and re-issued as necessary.

These proposals are to enable third parties to understand the nature of the works and the various construction activities associated with the development.

The AQDMP will be distributed to the Client and their consultant team and used for liaison with the stakeholders and other interested parties throughout the project. As information is updated and as the project develops, particular attention will be paid to the neighbours. This will ensure they are kept informed of progress and future works on the project. Communication will be via a fortnightly newsletter issued electronically and included in letter drops.

The information provided in this document is an overview of the key project activities for the enabling and construction phase at Horniman Museum and Gardens Statements herein are to be further incorporated into plans, procedures and detailed method statements from newly appointed subcontractors as the project develops.

Project Overview

The Nature + Love project consists of a new Sustainable Gardening Zone, including demolition of existing structures and the construction of a new glass house with external covered area in the nursery hub, paved terrace, paths, and landscaping for the Winter Garden, paving and planting for Community Wellbeing Garden.

The construction of a new cafe, toilet block, store house and play area within old boating lake to Nature Explorers Zone, interpretation panels and entrance gate and ramp on the Nature Trail.

Internally to the Natural History Gallery the aim is to consolidate the showcase layout and reduce the overall number of showcases to improve the overall access routes and pinch points between the showcases. Many of the existing historic showcases are to remain and be refurbished, some will be repositioned and reallocated, removed or dismantled and placed in storage. A number of the existing more contemporary showcases are to be either relocated or removed. New display cases are to be installed to meet the modern criteria in terms of environmental conditioning.

External works to the Natural History Gallery to include new roof coverings, louvres to eastern windows; enlargement of western plant enclosure; plant enclosure on west side of gallery; ductwork penetrations, guardrails to east elevation, new fencing and gates and other internal and external alterations to the elevations at Horniman Museum and Gardens, 100 London Road SE23.

Project Overview

Site Description

The Horniman Museum and Gardens (the Site) is in Forest Hill, Southeast London, within LBL. The eastern boundary of the London Borough of Southwark is separated from the Nature Trail by the houses and gardens located on the eastern side of Wood Vale.

The Site first opened as Surrey House Museum in 1890 in the Horniman family residence. In 1901 it changed its name to the Horniman Museum when it re-opened in a new purpose-built museum building. The site was gifted to the people in 1901 for their education, recreation, and enjoyment. This vision remains central to the Horniman today.

The site consists of a mix of high-quality collections displayed in the galleries on site; these span natural, multicultural, and musical worlds alongside 16 acres of well managed open space. The Museum offers community based learning, education and leisure programs and a wide range of performance events and activities. The Horniman serves a local, national and international audience. It is a popular local resource in southeast London.

The Museum is Grade II* listed and has seen new extensions over the years including, most recently by Allies and Morrison in 2002. The Gardens are extensive and range in style and form from Sunken Gardens, Grasslands Garden, to the Sound Garden, Bee Garden, Wildlife Garden, Meadow Field, South Downs Meadow, and Prehistoric Garden. The Gardens underwent a significant redevelopment project in 2012 which provided new opportunities for education and creative pursuits.

The site is free to access and open to the public all year round. The Museum is open daily from 10am – 5:30pm and the Gardens open daily from dawn to dusk (time of year dependent).

The key elements of the enabling works development about the potential impact on the surrounding areas are:

  • Secure site work areas using hoarding or Heras fencing panels.
  • Set up contractors compound to include site office and welfare accommodation.
  • Set up storage/staging areas.
  • Form new vehicular and pedestrian access routes.

Note: – All the above as indicated on the proposed Construction Management Site Plan NLP-FF-00-XX-DR-A-00119- See section 3.2 below.

From site possession, an independent Environmental Consultant shall establish the noise, dust and vibration baseline monitoring levels.

Main construction works phase

The key element of the works with regards to the potential impact on the surrounding areas is: –

  • Demolition works
  • Substructure works
  • Superstructure-Cafe
  • Envelope-Roofworks
  • External works-Sust
Roles and responsibilities

The appropriate resources will be supplied to cover the requirements of dust control on site to ensure that these are communicated effectively and acted upon in an appropriate manner. The site manager will be the person on site responsible for dust control and site activities in general. In the event of absence, responsibility will be assigned to another suitably qualified person.

Inventory and timetable of dust and NOx air pollutant generating activities

The following activities are identified as limited sources of dust emission to occur on this project (refer to works programme 023-0026 TMP1 in Appendix C & D Options).

  • Demolition-Weeks 2-14
  • Substructure-Excavation-Reduce Level Digs-Weeks 10-15
  • Superstructure-Frames-Weeks 16-24
  • Envelope & finishes-Weeks 14-30

See preliminary traffic movement plan below indicating maximum weekly traffic movements during the construction period. This histogram gives the indicative traffic movement based on 023-0026 TMP1 programme over approximately 71 weeks. The above is based on an average of 2 deliveries an hour on a “just in time” basis.

See Appendix C programme 023-0026 TMP-Maximum

The indicative traffic movements are based on the current allocated delivery slot of 9am to 10am (10 per week). Current restriction on traffic movement delivery times by LBL between 9-10 am to allow for school groups who may be travelling to and around site.
