The project comprised of a replacement private dwelling. The site is located on the Barclaven Road, Kilmacolm in Renfrewshire.
The building structure is predominately three storeys with a small undercroft and some rooftop terrace areas. A braced steel frame was adopted. Wind loads were transferred to the braced bays using diaphragm action, stressed skin timber construction at roof level and in-situ concrete on metal decking at upper ground and first floors. A curved warren truss has been used to span the 15m over the external garage area and also to create the 5m cantilever balcony. One of the main design considerations on this project was the lack of access to the site, hence the use of metal deck floors and short lengths of steel members which could be bolted together on site to form the truss.
Reinforced concrete pad & strip footings have been used for the foundations due to the site being predominantly rock. Due to a sloping site with high rock levels, care had to be taken with foundation design and levels, to ensure there was no unnecessary and costly excavation of rock. The use of BIM on this project helped avoid this by modelling the existing ground & rock levels. BIM model also assisted the fabricator and contractor with the complex geometry of the curved warren truss.
