We have recently undertaken a rather tricky installation for developer St George’s which is a member of the FTSE 250 company Berkeley Homes Group, a long-standing client of AVDanzer.
The luxury homes builder is developing a superb residential scheme called Sovereign Court in London’s West End. It will comprise 1, 2 and 3 bedroom contemporary apartments, penthouses and villas with prices from £989,950 – £1,499,950. With high land values these city centre developments are always tight for space but this one was on quite another level !
St George’s approached us over a year ago to see if we could help with providing welfare and office accommodation on this challenging site which had severely restricted access. We would not be able to offload using the traditional methods such as hiab or mobile crane.
The only solution was to utilise one of the site tower cranes to lift the units into place. However, as the crane was located over 55 meters away from where the complex was to be located, the capacity of the crane at this extended reach was limited to little over 2 tonne.
The team overcame this by subdividing the modules and omitting the internal plasterboard linings to reduce the weight further for those units located at the furthest extremity.
AVDanzer worked closely with St. George’s and the crane contractor, Joseph Gallagher to understand the limitations of their crane and its capacity to lift the units into place as well as the logistics of physically getting the units onto site off a very busy trunk road.
The modules were subsequently designed to meet those lifting specifications whilst not compromising the accommodation requirement. Despite the very limited ground space available to us, we found a solution to all of the complications and were awarded the contract – based on our ability to deliver this challenging installation.
The £250,000, 32-module welfare compound consists of sub-contractor offices on the first floor linked by external staircase to the welfare accommodation including toilets, drying room and canteen on the ground floor. Another unique feature which had to be designed-in was a 60 minute fire-resistant wall to one side, given the proximity to the new building which is a fire risk.
The units were installed during the day, so site activity had to be carefully planned to ensure the crane was available and that there would be no significant impact on the construction schedule.
We also worked within the abnormal load restrictions for residential areas which only allow us to bring in the lorries for unloading before 7am and after 10pm.
Commenting on the job AVDanzer’s Dan Holloway said: “This was another really interesting and challenging project and one where we had to work hard to find a solution. The team had to look at all aspects of the job, from the crane’s lifting capacity, to road access for delivery and ground space limitations. We were able to design and build a configuration which met all of the requirements and provided the client with a viable solution which secured us this prestigious contract.”
