The new school was built in the grounds of the old school, which continued to operate during construction. The old school was then demolished. The client was Newtown Council Education Services and the project was a design and build contract, which was awarded to ACE Construction in July The design was carried out by J Smith & Partners. Construction commenced in August 2014 and was completed in June 2016, six weeks ahead of programme. The new school will open in September The old school will be demolished and the site landscaped by April The construction cost is still to be finalised but is expected to be about 37.5 million, 2.5 million less than the target cost. In general terms the project proceeded in line with expectations. Issues relating to resource efficiency are highlighted in this report. Newtown Council set a number of objectives for the new school, which is intended to be a beacon project and a model for other new schools in the area. It was to be specifically designed to provide a stimulating learning environment that will help to improve the educational achievement of the pupils. The project was required to maximise the use of locally sourced materials and provide employment for local young people, and these aspects were used as factors in the tender assessment. The council required the construction to encourage the use of walking, cycling and public transport by pupils and staff. A BREEAM rating of excellent was a requirement. ACE Construction proposed in their tender that the WRAP RMP Process should be used as a way to set the agenda for all resource efficiency topics and track them through the design and construction stages. The client agreed to this and a Scoping workshop was held in August 2013, followed by a Design for Resource Efficiency workshop in September 2013, with the client, designer and contractor fully involved in both. These workshops were very helpful in selecting the key areas to focus on in order to achieve the BREEAM excellent rating and the council s specific objectives. These were then followed through during the design and construction stages, using the RMP Design Action Plan, Construction Strategy and Estimating and Monitoring Template. The final outcomes, including lessons learned, are included in this report, which is prepared by the whole project team.

2 Section 2: Scope of the RMP The final scoping template agreed at the scoping workshop in August 2013 is shown below. Components highlighted in grey have been scoped out of the project Reducing materials consumption 1 Level Basic Enhanced Stretched Metric Tonnes/100m 2 GIFA Target 3.2 Reducing wastage % waste diverted from landfill > 80 Increasing reuse and recycled content % recycled aggregate content by weight > 25 Matching the durability and lifespan of assets to service life Using resources with no scarcity and source security issues % possible BREEAM score > 36 Using products with lower embodied carbon % materials sourced within 25 miles by value 30 Using products with lower embodied water Reducing energy use during construction Reducing water use during construction Enabling water efficiency in use kwh 10,000 % improvement compared to notional baseline project > 36 Energy Performance Rating (EPRnc) > 0.36 Enabling energy efficiency in use % reduction in CO 2 emissions > 25 Enabling reuse and recyclability at end of life Use local labour wherever possible 2 Number of local people employed on site by contractor (new starts only) 25 The scope was appropriate for the size of the project and the state of knowledge at the time (3 s ago). Developments since then have put more focus on reducing embodied and operational carbon and water in order to meet the Climate Change Act 2050 targets. If the process was repeated now, even more onerous targets for energy efficiency in use and during construction would be set and targets would be set for products with lower embodied carbon and water and for water use in construction. More stretching targets for waste and recycled content would be set, more attention would be given to total material consumption and matching durability to lifespan 1 Where a row is shaded grey, the RE component has not been selected for action on this project. 2 Additional component added by the client

The SWMP was very useful; it is company policy to use this on all sites Plenty of recycled aggregates available in the locality, no problems beating the target. Required a lot of work chasing suppliers for information. Always below target with this one, but came close in the end. Found awareness in suppliers increasing as time went on. More realistic forecasting of waste, allowing for constraints of site and programme; better engagement with suppliers at an early stage. Clients should expressly require use of a SWMP now it is no longer a legal requirement, and should start it themselves Set higher target for future projects. Need to engage with suppliers at company level to establish what we want, so we do not have to chase them all the time.

10 RE Component Level Metric Target Estimate Actual Using products with lower embodied carbon Using products with lower embodied water Reducing energy use during construction Reducing water use during construction Basic % materials sourced within 25 miles by value to implement Net Saving k 35k Basic kwh 10,000 9,750 9, k 3k Comment Lessons learnt Owner The target was set relatively low, and we were able to meet it largely by sourcing all concrete, steel, asphalt and aggregates locally. It would have been harder to source the internal finishes, fittings and M&E plant locally. A lot of work was required to establish what materials could be obtained locally, but cost savings were obtained through reduced transport costs. This metric was used to accommodate the client s requirement for local supply of materials, so is not a true measure of embodied carbon, though it does reflect reduced transport. This is standard company policy for ACE Construction, applied on all sites. Actual measures of embodied carbon would be required for future projects. This could be used as an additional measure. Engagement with suppliers at company level to ensure they can supply the necessary information. Collate information and lessons from all sites to ensure good practice is replicated across the company and cost savings maximised. Requirements to reduce energy use during construction are likely to increase to meet the Climate Change Act targets.

12 Section 5: Lessons Learnt Client feedback: Newtown Council As the client, we found the RMP Process very useful for translating our strategic objectives for the new school into tangible measures which could be tracked through the project. Setting up an integrated project team and holding the Scoping and Design for Resource Efficiency workshops at an early stage helped to focus the project team on these objectives and how they could be realised. The designer and contractor brought in several RE components that we had not required and raised the level of implementation of several others, adding value to the final building. Regular reporting at monthly meetings using the various RMP documents helped us to see how progress was being made and enabled adjustments to be made quickly when necessary. The final report gives us a record of what has been achieved which will be very useful for informing councillors and the public about the project. We will consider making the RMP process a requirement on future contracts. Design feedback: J Smith & Partners As the designer, we found the RMP process useful in bringing together a host of different requirements in one place and enabling us to see how they were all linked. The proactive approach by the client and interaction with the contractor was vital in making the process work effectively and resulted in implementation of more RE actions than would otherwise have been the case. These also yielded cost savings to the project as a whole, so were well worth pursuing. We found the RMP simplified the paperwork by providing a framework to bring it all together. Construction feedback: ACE Construction Ltd We were familiar with the RMP from previous work with WRAP under the Halving Waste to Landfill commitment and felt that it would be a suitable process to use on this project, to bring together a number of client sustainability requirements and an overall BREEAM excellent requirement. Our designers, J White & Partners were willing to try the new process. Crucially, the client was also willing to try this and was proactive in setting up an integrated project team to deliver the project. The early workshops on Scoping and Designing for Resource Efficiency helped the project team focus on the key issues and how they supported the client s objectives for the new school. The RMP helped maintain this focus and impetus throughout the project. We had concerns about the amount of paperwork that would be required, but this was largely a case of coordinating information we were already required to obtain for the specific objectives set by the council. The end result was the successful implementation of a number of RE measures on the project, coupled with overall savings in cost. We have since used the RMP process on other projects and found it to be very helpful.
