Construction Best Practice, Greenwich Millennium Village, Greenwich Penninsula

Introduction

The Greenwich Millennium Village (GMV) is a housing development under construction since 1999, providing 1400 new homes. The development is designed to minimise environmental impacts and maximise the sustainability of the project. GMV is a joint venture development by Countryside Properties and Taylor Woodrow Developments, in association with English Partnerships. In addition to sustainable waste management, GMV presents best practice in a number of other areas, including use of materials, energy consumption and provision of wildlife habitat.

Description

GMV exceeded its target to reduce onsite construction waste by 50%. The waste reduction strategy involved the use of SMARTAuditTM, part of the BRE SMARTWasteTM tools.

SMARTAuditTM enables waste streams to be benchmarked and categorised by source, type, quantity, cause, cost, quality, condition and potential. This data is used as a springboard to identify and prioritise actions to reduce waste arisings (producer responsibility), reuse at source and to maximise recovery to extend material life cycles.

The waste management strategy included project management and site management measures. The implementation process was smooth and all targets were met due to early planning and consideration.

To implement the waste management strategy and realise the targets, several actions were taken during the early stages to: 

  • establish a company or site benchmark against which to measure results 
  • contractually oblige sub-contractors to cooperate with waste minimisation 
  • ensure that all suppliers of materials provide returnable or recyclable packaging 
  • engage all site workers with toolbox talks and briefings - identify key waste products likely to arise during construction and implement waste reduction plans 
  • partner with waste management contractor to maximise recycling and reduce disposal costs 
  • agree on-site re-use and recycling as part of quality management 
  • monitor and publish waste performance figures

Design/specification

Waste reduction was considered from the outset with the incorporation of offsite manufactured products such as bathroom pods, cladding panels, balconies, precast stairs, timber frame and rainscreen panels. A prefabrication plant on site for lightweight structural components was erected during Phase 2, where elements were manufactured to size.

Supply chain 

  • British Gypsum, the plasterboard supplier, took away all segregated plasterboard offcuts to be processed and put back into the manufacturing process 
  • rockwool collected all unusable insulation offcuts from the site and where possible, offcuts were used to fill gaps rather than cutting from a fresh roll 
  • all timber pallets that arrived on site with plasterboard were returned to the local plasterboard merchant for further re-use

Construction best practice 

  • a comprehensive segregation and recycling scheme was set up on site and included timber, cardboard, paper, concrete, site metals and drinks cans 
  • timber formwork which was generated in large quantities was shredded to form a ground covering mulch 

Occupation

All residents were provided with internal and external recycling facilities. Internal recycling bins are integrated into kitchen units.
