UTMANING

Bostadsområdet Vista som ligger i nära anslutning till Amerikanska ambasaden i London är ett komplex bygge. Totalt är det 456 lägenheter fördelat på fastigheter mellan sex till sexton våningar höga. 

Med över 3,500 genomföringar i bjälklagen ville ansvariga arkitekterna att genomföringarna skulle vara projekterade inför offereringsskedet. Stuart Mills från Scott Brownrigg förklarade varför “we were keen to ensure these were prescribed at tender, meaning we’d only need to alter them on rare occasions that buyers bought adjacent flats, requiring major internal reconfiguration"

LÖSNING FRÅN HILTI

Mills såg direkt potentialen med Hiltis ingjutningsenhet “I liked its simplicity - there’s not much that can go wrong with it as opposed to the workmanship issues you’ll be faced with when creating service openings using traditional methods"

”Positioning is critical as the detail is obviously not a flexible one, but here at Vista there are some tight bathroom voids and it’s helpful that the collar comes in different sizes as well as ratings,” addera han.

Begley’s opinion is echoed on the design side by Stuart Mills of Scott Brownrigg saying that depending on the level of desired flexibility of the project, he “wouldn’t have any reservations specifying the cast-in device on future projects” and that he “was happy with Hilti’s ‘invaluable’ support throughout the construction phase”.

Michael Begley, Senior Project Manager på MPB Structures uppskattade att man kunde använda nya generationens ingjutningsenehter från Hilti vid byggandet av VISTA.  “The latest cast-in device’s design modifications have increased its capacity to be tailored to different on-site scenarios. The new device is squarer, more stable and made of denser plastic. That really helped when it came to fixing together the 150mm extension pieces in areas like the podium, where the slab can be 800mm thick in places. 

"It’s a case of just marking up, screwing in and job done – the screw on protector caps are also much better. And the way the latest models can snap together with only a 52 mm gap between adjacent 110mm pipes – as opposed to the former 105mm – allows the detail to be more space efficient. This also makes it easier for devices to fit in around rebar runs, its compactness requiring less bending of steel around their positioning.”

“It also brings more cost surety to a contractor when tendering, avoiding potential logistical and programmatic costs associated with building open service holes on a working site”. To Begley, Hilti’s Firestop cast-in device “helped put the project nine weeks ahead of programme”.
