This project was for the Design and Construction of a 35,000t per annum Anaerobic Digestion Facility on a Brownfield site in Cardiff as Principal Contractor.

The project consisted of New Access Roads, Car Parking, Reception Building, Tank Farm and a Bunded enclosure. There were many challenges on the project, such as Design & Build, CIRIA Guidelines and contaminated land, to name only a few.

The project involved re-designed layout and new access roads and improvement of the existing Tidefields Rd, under a Section 278 Agreement and S104 agreement, along with all Car Parking Facilities. The existing road had suffered from considerable differential movement, and close liaison with Cardiff CC Highways Department was required to upgrade an access road for local authority adoption. Through the design development process close liaison with the Cardiff Planning Authority was required to ensure proposed changes were acceptable to the authority, prior to fully worked up design and submission of planning amendments.

There was a Contractual requirement to achieve CEEQUAL Very Good (Civil equivalent of BREEAM). The project faced a number of environmental and ecological issues, including:
Contaminated Site Contaminated with asbestos Knotweed
Ecology – Oystercatchers, bird nesting survey, indigenous plant landscaping.

Early collaboration with the client, processing contractor and designers, resulted in construction solutions and value engineering options for a complex engineering scheme. Specialist Sub Contract Trades were chosen for the relevant experience required and from our approved list.
