Glasgow Airport Investment Area – Ancillary Infrastructure by RPS and Wills Bros Civil Engineering

Описание: From their offices in Dublin, Cork and Galway, RPS Group provided design services for Wills Bros Civil Engineering on the Glasgow Airport Investment Area – Ancillary Infrastructure project, which is being led by Renfrewshire Council and jointly funded by the UK and Scottish governments through the £1.13bn Glasgow City Region Deal. The project provides improved connections to Glasgow Airport including the realignment, upgrading and extension of the existing road network, a 70m long two-lane bridge for pedestrians, cyclists, and commercial traffic across the White Cart River, a new 100m single span pedestrian and cycle bridge over the Black Cart River, and new and improved junctions and connections to existing cycleways and pathways. It also included an engineered road crossing of a 132 kV oil cooled buried electrical cable.

RPS developed an innovative, unique and low carbon solution to the problem of constructing a new road over a set of buried electrical cables in a soft floodplain environment. The cables had fragile oil-filled cores were very vulnerable to damage by settlement and movement, vibration, overheating and accidental damage during construction. The original design provided for a carbon-intensive bridging structure, supported on 22 concrete piles - each 30m deep - with precast concrete beams spanning between them. The alternative innovative design developed by RPS comprised an ‘embankment’ formed with recycled plastic Geocellular units, normally used for water storage applications. These units are very lightweight, being over 95% air, and yet still robust enough to sustain traffic loads.

The carbon footprint for this Geocellular design was 197t CO2e, which is 87% lower than the original which had a carbon footprint of 1,546t CO2e.

This project is one of our four projects shortlisted for the Engineering Endeavour Award. Cast your vote before noon on Friday, 9 December: https://www.engineersireland.ie/Profe...
