Dougall Baillie Associates

Case Study One
PROJECT: Kingston Quay
CLIENT: Barratt West Scotland

Full structural consultancy service for new build development of eight storey modern executive style apartments. The development includes a communal courtyard and basement car parking throughout to serve the 372 homes.

The structure consists of a structural steel frame with concrete floors on the upper levels and a reinforced concrete sub structure, basement and capping slab.

Extensive retention works both permanent and temporary have been developed within the basement area to retain the surrounding adoptable roads.

Case Study Two
PROJECT: Leverndale Redevelopment, Sector C
CLIENT: Miller Homes

This project required DBA to carry out the structural design work for 3 very different multi-storey residential blocks. Block A was a traditional pre-cast block on reinforced concrete strip foundations. Block B was of timber framed construction on reinforced strip foundations. Finally Block C was a five storey block made up of a steel frame for the lower three floors with a two storey timber kit block on top of this.

This block was to be supported on a piled foundation with reinforced ground beams. Block C in particular proved to be a challenging task for the design team, with many of the challenges arising due to strict planning requirements which were imposed by Glasgow City Council.

The aim was therefore to produce a design which could meet with these requirements but remain profitable for the client. For this reason the part steel frame, part timber frame was selected even though it was far from the simplest solution.

Case Study Three
PROJECT: Riverside Point, Braehead, Renfrewshire
CLIENT: Redrow Homes

Situated in the new residential zone of the prestigious Braehead development, this project represents Redrow’s flagship Scottish development. DBA were employed to carry out and certify (SER) all elements of Structural design associated with the project.

This started with the foundation design. The site investigation indicated that due to the low bearing capacity found on site that the ground would need to be improved our piled foundations adopted. DBA organised tenders from piling contractors and ground improvement specialists. It was decided that the ground could be suitably improved using vibro-compaction, which provided a substantial cost saving over piling. Foundations were then designed for each house based on the improved ground.

DBA were also required to carry out detailed structural designs for some complex bespoke details which were being employed by the client due to the high profile of the project. SER certification was provided for all of the super structure designs on the site.
