Heavy duty trackway required to protect primary school grounds
The project
Our client, DSM Contract Lifting, required our assistance at a primary school, where a 450T crane was to remove two old generators and then replace them with two new generators. Heavy-duty trackway was essential for providing access along with building a safe area for the crane to set up for their lifts. Our trackway also would prevent any damage, from such a heavy machine, to the tarmac of staff car park and the school playground.
The location
Fenstanton Primary School, Abbots Park road, London, SW2 3PW
The challenges and heavy-duty trackway solution
Our priority was to protect the school car park and grounds from the pressure of a 450t crane capable of producing 17t per axle of pressure as a point load. After discussions relating to the exact route in which the crane was to undertake, we agreed that elevating the trackway up over the curbs was the best solution. This would give us a double element surface cross bonded and a much larger spread of width. The 4.23m curb to curb simply wasn’t enough to distribute throughout the trackway and into the ground beneath.
Another challenge we faced, was ensuring the trackway itself wouldn’t leave indentations in the tarmac. So, we recommended the use of our ultra-thick interlock cushion underlay to eliminate this potential problem which our customer was delighted with.
After we had agreed on a layout and had a plan in place suitable for the crane and its specification, we planned the loads in and out with the logistics department. Some of the car park was still being used and the entrance was also used for a variety of reasons, so this required navigating. The public were also in and out of the pedestrian route at the entrance, so we had to segregate our work for the safety of others during the installation. We planned scheduled loads during the day which would enable loads in and out using our equipment to withstand the weights.
The requirements
- 153 aluminium DTH Panels
- 14 half-panels
- 600sqm cushion underlay (to add extra protection to the tarmac surface)
- 10 PVC cloaking mats (to create a safe access and egress to the crane pad)
- 50 sand-filled bags (for levelling)
The crane lift went without a hitch and the trackway did its job efficiently and impressively. The team who took the trackway up were just as efficient. We handed the car park back to the client on time and without issue. We WILL be using you again! Thanks from us at DSM!
