We can design any type of building structure, ranging from large multi-storey schemes to spiral staircases, in all materials.
The company has been involved in several hundred bridge schemes, primarily new structures and with a particular speciality being steel footbridges of all types. These have ranged from traditional truss and plate girder bridges, to cable-stayed and box girder spans.
We have designed many motorway sign gantries, both traditional portal type and the new generation, cantilever variable message sign gantries.
We can advise on structural failures, including welding and fatigue issues.
Electrical transmission structures
Bill Buchanan has extensive experience of designing structures to carry electrical transmission works, both in the UK and abroad.
Masts and towers
We have a long history of lattice tower and mast design, stretching back to the old Tubewrights towers of the 1960s. More recently, we have designed and checked several towers, both in the UK and abroad.
We were also recently awarded a contract by West Lancashire District Council for the design and supply of a 30m tower to support microwave equipment, as part of a local CCTV monitoring scheme.
We are employed by several manufacturers to provide design support.
Many jobs, from buildings and bridges to towers and lighting structures, involve us in providing foundation design and advice. These can range from simple footings for modular buildings, to piles and reinforced concrete pads for bridge trestles. Recent schemes have included extensions to Torquay and York Hospitals, which involved difficult ground conditions and numerous uncharted underground obstructions.
Heavy lifting schemes
We work for several lighting column manufacturers, and for whom we have designed and checked standard columns and many non-standard applications. These have included ornate and feature lighting structures in a wide variety of materials.
We have an in-house computer program to design lighting columns, including those carrying catenary loads, to both old (BS 5649) and new (EN 40) standards.
The new EN40 program is available to buy, and has been sold to several customers, including Corus.
