A Bespoke Refurbishment
A total building envelope refurbishment solution by Tata Steel was selected for the conversion of a derelict 9,500m2 1960’s portal-framed building into a prime, lettable warehouse, distribution or manufacturing facility at Pimbo Point, Potter Place, Skelmersdale, Lancashire. Pimbo Point is situated close to Junction 5 of the M58, providing excellent access to the M6. It is owned by nationwide commercial and industrial property investor Spencer Holdings Ltd. Spencer owns and manages over five million square feet of industrial and commercial properties with over 1000 tenanted units. The original building was in a pretty dilapidated state. It had a number of failed areas for both the existing brickwork and asbestos cement sheeting. The air leakage rate was high, at about 27m3/hr/m2, at a rate of 50 Pa, well below modern energy efficiency standards The project was managed by Greenbrook Construction, Spencer’s own multidiscipline contractor. Company Director and Project Manager Jonathan Halfpenny commented: “I think it’s fair to say in these challenging times that the market is more demanding and where there is more accommodation available, tenants are looking for a quality building as well. Providing that quality refurbished building, we hopefully are able to set ourselves above the competition and make our units more lettable than others.
“Sustainability is a major consideration in modern development. In our refurbishment of Pimbo Point, all of the cladding, including the old asbestos roof, was completely removed and replaced with a built-up insulated cladding system, improving the overall efficiency and anticipated lifespan of the building.” MITIE Tilley Roofing, Manchester was the appointed installer. Operations Manager Eric Podstolec explained how the new roof was constructed: “Our first task was to carefully remove the asbestos sheeting, in accordance with current regulations. We also removed the original steel gutters, which were also replaced, having failed at joints. “We then installed a new built-up insulated cladding system to the roof comprising of R32 external profile in Colorcoat Verso®, quilt insulation and 0.4mm LP1000 liner to achieve a U value of 0.25W/m2K. The walls were also constructed using the Tata Steel built-up insulated cladding system utilising their C32 external profile, quilt insulation and LP1000 liner to achieve a U value of 0.35W/m2K in accordance with ADL2.” A key requirement of Spencer Holdings was to ensure the building complied with the requirements of ADL2 in terms of both thermal and air leakage performance. Tata Steel specified a built-up system that guaranteed the building envelope not only met the necessary building regulations, but that it would also benefit from reduced energy consumption throughout the lifetime of the building. Given the previous air leakage rate of 27m3/hr/m2, it was imperative that the cladding/interfaces were designed to minimise the air leakage rate. Tata Steel worked with both Spencer Holdings and MITIE Tilley Roofing to ensure that the design details used on the project delivered the required improvement to the air leakage rate. By achieving good levels of air-tightness and thermal performance through the building envelope, it was possible to construct a facility that operates efficiently in terms of both energy usage and CO2 emissions. With environmental considerations, government legislation and faced with escalating energy bills, considering a building’s long term sustainability credential simply makes good business sense. Tata Steel Colors offer the Repertoire® Colour Consultancy which is a bespoke colour matching service used on a regular basis for certain clients. Spencer Group have a clear identity in terms of their buildings, and Colors were able to offer a specific colour solution for this project. Spencer Holdings Chairman Jim Spencer reflected on the final result: “When we do a refurbishment job, we do it to a high standard. In fact, it’s part of our policy to get the finished job looking at least as good as new. “Surprisingly, we get people saying ‘your branding is very good’, simply because when they go onto an estate and see the green strip they don’t need to ask whose estate it is, they already know who the owners are.”
