The Macclesfield Wastewater Treatment Works (WwTW) project represents a landmark collaboration between Shay Murtagh and our partners, delivering a state-of-the-art storm inlet works solution using precast concrete panels. With over 220 precast panels and two precast raker beams, each weighing over 50 tonnes, this project showcases the value of off-site precast construction in addressing space constraints and operational challenges on live sites.
The use of precast concrete panels allowed for significant efficiency gains. By adopting a Design for Manufacture and Assembly (DfMA) approach, the project achieved:
- An 80% reduction in site personnel.
- A 95% reduction in working at height activities.
- An 80% reduction in in-situ concrete works, minimising risks in a live environment.
These significant reductions in site personnel, working at height activities, and in-situ concrete works highlight the efficiency and safety advantages of adopting precast construction methods, particularly in challenging, space-constrained environments like Macclesfield WwTW.
The delivery strategy further contributed to environmental sustainability. Shay Murtagh coordinated 80 shipments of precast components, compared to the 300 concrete wagons that an in-situ method would have required. This streamlined approach led to a 50% reduction in embodied carbon, reduced local disturbances, and minimised material waste.
R.Betts Construction expertly handled the on-site installation, ensuring seamless integration of precast units with bases poured around the structures, screeds laid to falls, and all joints sealed. The final structure successfully passed water testing, confirming its robust design and build quality.
This project reflects our expertise in delivering innovative precast concrete panel solutions that meet operational, environmental, and safety challenges. Shay Murtagh continues to lead the way in providing sustainable and efficient off-site construction methods for critical infrastructure projects.
