The Marshall Mercedes Southampton work consisted of the refurbishment and extension of a derelict heavy good workshop, construction of a standalone steel framed used van sales building with associated drainage and HGV hardstanding areas. 

Foundations were formed from large pads mass filled with concrete. The steel portal frame was then erected to provide an 8 bay truck workshop facility, together with a new parts store and workshop admin area. 

To the existing Marshall Mercedes Southampton building, all existing finishes and services were stripped out and replaced and a number of walls removed to provide a new after sales reception area together with welfare and office facilities. The existing workshop was refurbished for light commercial vehicle service and repair.

The walls and roof to the existing building and new extension were then stripped and clad with new insulated Kingspan panels; steel sectional doors were added to the new openings, HGV service areas had workshop pits formed in the new ground floor slab structure together with a steam wash facility. 

Inside the existing building, we carried out a number of structural alterations including removal of load bearing blockwork walls, installation of padstones and steel supporting beams, blocking up openings and forming new door and window openings to facilitate the proposed layout.

There were a number of service pits within the concrete pits that contained asbestos pipe lagging; a number of the existing fuse boards contained asbestos flash bands that needed safe removal and disposal. Horizon Environmental carried out the safe removal and disposal of the asbestos containing items prior to any works commencing in the locations containing asbestos. 

The used van sales building at Marshall Mercedes Southampton was formed from a steel portal frame with cladding and glazing systems installed to match the existing showroom building. The hard landscaped areas of the site were extended to provide the dealership with a greater display area for used van sales as well as customer parking for HGV & LCV vehicles. The existing crushed material forming the compound was removed and a HGV specification sub base was installed together with a 200mm thick tarmac surface, approximately 2500m2. Perimeter fencing and gates were replaced to provide the site with greater security together with timber panelling to the rear elevation to screen the adjacent railway line.
