South Tyneside-based Castle has completed works at the former TRW Automotive Systems site at Washington.

Appointed as principal contractor by the abrdn Property Income Trust, Castle has refurbished the 150,000 sq. ft facility, which will be a distribution centre for the UK’s biggest, dedicated parcel delivery specialist.

Headquartered in Hebburn, with a headcount of over 100 staff and offices in Glasgow and Edinburgh, Castle, which last year recorded £30 million turnover, is one of the UK’s leading providers of building services, offering a wide range of high-quality engineering and contracting services covering all aspects of building, mechanical, public health, renewable and electrical engineering.

Andrew Dawson, managing director at Castle, said: “It was a great honour to be awarded the contract to refurbish such a well-known and significant facility. We take great pride in playing our role in supporting local investment and regeneration.”

The scheme of works consisted of utility disconnections, demolition and strip out, earthworks, retaining structures, drainage, including attenuation, RC yard construction, parking areas and roadways, a vehicle re-fuelling area, van washing areas, re-surfacing, fencing, hard and soft landscaping, roofing works, cladding works, new doors and dock levellers, replacement of mechanical and electrical services throughout the facility, roof mounted photovoltaic panels, replacement joinery and finishes, cleaning, statutory compliance testing and assessments.

Castle has successfully introduced renewables into a 30-year-old building through the introduction of a roof mounted Photovoltaic sealed panel 1168kWp system which will generate 942,930kWh per year, which is the equivalent of supplying 235 homes and is estimated to provide 241,390kgs of CO2 carbon offset for year one. These works have allowed Castle to upgrade the facility from a Grade C rating to a new energy rating of 10A / EPC A.
