Project Case Study: Eco-Refurbishment of 227 non-traditionally-constructed properties

Project Case Study:

Eco-Refurbishment of 227 non-traditionally-constructed properties (Wimpey-No-Fines, Wates & Unity Flats) delivered in 3 phases

Client: Corby Borough Council

Westdale were appointed the principal contract to project-manage and deliver an investment & regeneration programme to 227 properties of varied non-traditionally constructed archetypes, including Wimpey-No-Fines, Wates and Unity four-storey flats.

Scope of Works: The investment programme required the survey and subsequent removal of non-licensed Asbestos, enabling works, the installation of External Wall Insulation, coupled with the replacement of soffits, fascias, gutters and rainwater goods, providing a long-term solution to these tired-looking properties.

Structural Issues: Westdale worked closely with Corby Borough Council’s appointed client agent, Michael Dyson Associates, to undertake structural surveys, agree upon and complete structural/remedial works prior to the installation of External Wall Insulation; this included a combination of minor surface crack repairs- through to more significant structural remedial works.

Programme of Works: The works were phased in a logical, intuitive manner, based upon geographic locations and property archetypes. Phase 1 of the measured-term contract saw the successful delivery of 85 Wimpey-No-Fines properties.

Pilot Property: The client identified two pilot properties in prominent locations, which were completed prior to the delivery of the main programme. This approach served two purposes: it provided residents with an opportunity to visualise the uplift to their homes. It also allowed all site-based operatives and sub-contractors the opportunity to fully understand & communicate their individual requirements. This enhanced understanding between delivery partners facilitated a more efficient and seamless delivery of the main programme.

Tenure-Blind: Corby Borough Council was keen to include private householders in the programme, who had purchased their homes through the Right-to-Buy scheme. Through an effective community engagement campaign, consisting of Press Releases, co-branded marketing campaigns, etc. Westdale ensured that private householders were offered the same best-value rates as procured by the client.

Thermal Performance: In accordance with BS EN ISO 6946 : 2007 and BRE Report BR 443 : 2006, achieved a thermal conductivity (U-value) of 0.032 W/m–1·K–1.

Fire Rating: Westdale specified a Non-Combustible EWI system with high polymer/standard cementitious base coat render prior to applying the topcoat finish, tested and validated by BBA (certificate 13/5065 Product Sheet 1,2,3,4 &5.)

The EWI system included EPS insulation, which, when tested as a completed system achieved a European Fire Classification B, s1-d0 (BS 476 fire class ‘O’). The system complied with the following:

The Building Regulations 2010 (England and Wales) (as amended) / The Building (Scotland) Regulations 2004 (as amended) / The Building Regulations (Northern Ireland) 2012 & NHBC Standards 2014

Engagement with Local Schools: Westdale proactively engaged with local schools to ensure that children living in the vicinity were fully-briefed over the (potential) risks of active construction sites. Our mascot, ‘Westy’ helps to deliver serious messages in an interactive and fun manner.

This current investment programme follows on from a number of successful refurbishment projects, including these properties as Argyll Street – which were treated to the full ‘Artbrick’ finish.
