Collins Construction commissioned LSJ Engineering to work on a project at Notting Hill Gate, designing acoustic enclosures and a bin store. Although challenging, we’re pleased with this job…
- Client: Collins Construction
- Structural detail by: the LSJ team
- Job Duration: 2019-2020
The main works were a refurbishment and remodelling of an office and retail space next to Notting Hill Gate station.
The building had two floors added, making it five stories high! A new rooftop air handling plant had to be installed bearing onto the CLT roof decking.
Collins commissioned us to design galvanized steel enclosures that supported, and hid, the plant. Working as a team with Collins, the M&E supplier, the project architect and the acoustic louver cladding contractor, we carried out a full structural design.
Our challenge was supporting the plant enclosures on a timber CLT roof deck. We introduced steel spreader beams that spanned the existing steel structure below the roof deck, then built the structures onto these.
Each enclosure is on a different roof area and level of the building. We used a City Lifting 5 axle Spiering mobile tower crane to reach the different areas, deliver and erect the structures. The structures weighed between 5 and 10 tonnes in total!
Following this, Collins asked us to replace an existing ground floor bin store palisade fence enclosure, using similar details. There was no requirement for acoustic louvers, only visual ones to screen the area, so we supplied and fitted them in powder-coated aluminium. Spreader beams at base level were still required, because the mains services running below the existing concrete slab made digging foundations risky.
Here are some of the plans for the project, plus a stunning rooftop view during construction! What do you think of the finished enclosures?
