Aarsleff Ground Engineering has completed its largest ever project to date, the piling contract for homeware giant The Range’s new mega shed distribution centre in Avonmouth, Bristol. The project, awarded by McLaren Construction on behalf of developer Stoford Properties Limited, commenced late July 2016 and saw Aarsleff install over 15,000no. precast piles to support both the main slab and roof stanchions of the completed structure as well as a number of peripheral buildings, such as sprinkler tank bases. The majority of piles for the project were 250mm section DPC, with the remainder being 300mm piles, and ground conditions expected to be a significant depth of tidal flat deposits.
The piles born onto Mercian Mudstone, which is typical of the strata suitable for a DPC approach. Speaking about the project Kevin Hague, General Manager at Aarsleff Ground Engineering, said: “This is the largest piling project that Aarsleff UK has ever undertaken in its 25-year history and is a tremendous vote of confidence in our precast piling solutions. It is also our first project for McLaren Construction and given the scope of works it highlights the high degree of trust they have put in us, the result of our previous dealings with them and our industry reputation.”
The contract win was a collaborative solution, with Aarsleff assisting McLaren during its own efforts to win the project by working with them and their chosen external designers to assess the likely cost implications of various loading scenarios for the then-unconfirmed roof loadings. Aarsleff also highlighted the twin issues of both negative skin friction and the cost implications of using various joint types, which helped the client make their own successful offer in a well-informed manner as to the potential structural and geotechnical risks involved with the completion of the project.
