Safety & Environment

During the development of the scheme Carney’s proposed to use a 1.5t excavator with concrete percussive drill attachment to avoid the risk posed by HAV and maintained production rates for the works. This was presented to Highways England who were satisfied the controls were in place to protect the workforce from HAV and permitted the work activity to be commenced. 

While the COVID-19 pandemic did come to bear on the project progress was maintained by increasing site resources, implementing segregations between the teams to provide working bubbles and tripling the site vans to ensure operatives could remain separate when out of works. Full additional compliance to site controls was implemented including onsite temperature checks, individual operative risk assessments, hand cleaning stations, rotation of breaks etc. works progress was improved upon with the additional resources and rotated shift patterns utilised. 

Local engagement with UNICEF was championed by Carney donating used / spare materials for construction of schools and nurseries. 

Quality

Carney Construction currently have been originally awarded just the FRC package and the RECO Wall contract was awarded later due to out clients satisfaction with the workmanship, productivity and value brought to the project when comparing us with our competition. 

By utilising our own shuttering systems and developing bespoke temporary works designs Carney Construction have been able to provide high levels of concrete finish requiring minimal post striking work, able to be completed within the same night road closure, critical to the safe delivery of the project. 

Carney Construction site team have been recognised by their quality with important additions of bridge bearing installation and being present to provide supervision for bridge beam installations, this is key work items which required the highest level of accuracy when working.

Productivity

Early engagement with permanent works designs has helped avoid problems holding up progress onsite, Carney Construction have actively raised concerns with the TQ process and proposed solutions where possible. 

Carney Construction have managed to decrease overall construction programme bringing both time and cost saving while maintaining high standards across the site. 

Conclusion & Summary

Carney have been praised for the workmanship of the site team allowing client engineering team to focus on programme and progress management. The client is happy to recommend Carney Construction on future works and is currently discussing future packages, summary of development: 

  • Zero Harm achieved 
  • Full construction support available including design engagement, temporary works designs, methodology and construction simplification. 
  • Vibration monitoring and innovative solutions to reduce risk. 
  • Specialist plant able to provide peace of mind when working around critical services.
