Dudleys Consulting Engineers has completed works to deliver a major new 40,000 sq ft industrial development at Calder Park in Wakefield. The £3.5 million scheme by Marrtree Investments now offers nine high specification trade counter units ranging from approximately 3,500 to 5,000 sq ft.
With a prime location at Junction 39 of the M1 motorway, Marrtree Business Park delivers much needed, new build warehouse accommodation at the heart of the established Calder Park. Existing occupiers include National Highways, West Yorkshire Police, and Taylor Wimpey Homes with the business community well served by food and drink amenity.
Dudleys Consulting Engineers was engaged in early 2024 to provide specialist advice on the development, owing to the site’s previous history as an open cast mine. Its appointment was pivotal in ensuring that the project could progress safely and efficiently. The team carried out comprehensive site investigation works, addressing concerns about the possibility of an unrecorded quarry shear wall traversing the area.
Through careful analysis and assessment, Dudleys provided reassurance to Marrtree and helped mitigate any risks associated with the site’s complex ground conditions. Its civil and structural engineering expertise was instrumental in supporting the creation of an economically viable scheme, ensuring that the development met the highest standards of safety and quality.
Andy Walker, Managing Director at Dudleys Consulting Engineers, said,
“We are delighted with the completion of works at Calder Park, marking another collaboration with Marrtree Investments. This was the final parcel of land available for development within Calder Park and considered a strategically significant undertaking for Marrtree as part of its expanding portfolio of high-quality, new build industrial sites.
“We were pleased to work closely with C&W Architects, STP Construction as the main contractor, and Kirby Welch Associates in the role of project manager. In addition to conducting detailed site investigations and implementing necessary remediation measures, we collectively remained attentive to the proximity of a 100-acre nature reserve adjacent to the development, ensuring that environmental considerations were thoroughly addressed throughout the course of the works.”
Dudleys has previously delivered full civil and structural engineering consultation for Marrtree Investments at its 70,000 sq ft Sowerby Gateway scheme in Thirsk, and its 27,000 sq ft development at Clifton Moor in York. Further instructions are soon to be announced.
