Challenges
The Architect was very keen on optimising the use of digital modelling and BIM, including the use of REVIT families for the 2 main rainscreen systems. Sotech provided aluminium panel Revit families.
The original design specified cast components, however the manufacturer’s minimum quantity made this prohibitive. A fire resistant alternative was required within cost plan constraints.
This is the first time A²O has installed a slate facade, so preemption of any issues with installation was essential for smooth and consistent progress.
Window design, with the windows inset in the slate facade, was a challenge, requiring custom manufactured pods.
Inclement weather was a challenge, with the six months on site being among the wettest on record. The installers could often only fit in half-days and had to travel from Birmingham.
Delays were caused by two other parties on site, required A²O to have to return to site when certain areas had already been all but completed.
The client was looking for a more stylish look, in response to their customer survey for visitors to the local business and university hub.
Solutions
A²O’s BIM champion astonished the Architect with his passion for Revit and created the slate revit families. The model allowed for optimisation of the panel and slate layouts and designing out waste.
The supplier proposed slate as an alternative. Not only was it viable, it has also proved the surprise success of the project. The slate is A1 fire-rated, highly resilient and, at the same time, affordable.
A²O organised a slate joint CDP for the architect and facade designers, leading to more accurate scheduling, keeping the project on track.
The prefabricated window pods were designed to completely close off the window openings, acting as head, jamb and sill.
The A²O installers turned up day after day, including half days, working in all weathers and in parallel on 3 facades, to keep to programme despite the difficulties.
The works progressed as per programme with any delays mitigated by the closing working relationship between all the project team.
The monochrome slate elements bring a slick feel to the hotel facades, setting off the branding which looks clear and impactful from afar.
