Steelwork completes on UK’s largest-ever speculative development

Working on behalf of ISG, Severfield has completed the erection of 4,900t of steelwork for two distribution centres at Panattoni Park, Avonmouth, which is said to be the UK’s largest-ever speculative development.

The two 17m-high units will offer 37,718m² and 82,727m² of floorspace respectively.

Sustainability is at the heart of the project as both units are aiming to achieve a BREEAM ‘Excellent’ rating and an EPC rating of ‘A’. They will also benefit from sustainability features such as roof-mounted solar PVs, rooflights and EV charging points.

Working on a design and build contract, Severfield, said a sustainable approach was undertaken, so that all of the steel sections used for the project are as efficient as possible.

Once the site was ready, Severfield began its erection programme with the larger Unit 2. This portal–framed building is 425m-long (53 bays) x 188m-wide and comprises five 37.6m-wide spans.

Predominantly using three mobile cranes for the erection of each building, both unit’s spans were erected with each rafter being lifted into place in two pieces.

The smaller Unit 1, measures 255m-long x 144m-wide and consists of four 36m-wide spans. Similar to its larger neighbour, this building also contains a two-storey office with a rooftop plant deck and a two-storey hub office.
