At the beginning of April 2019, Jack Tighe Ltd were awarded this contract to scaffold, encapsulate, clean, blast and paint the structural steelwork at Bardney Bridge. We sub-contracted the scaffold and encapsulation aspects of the work to two existing members of our approved supply chain, SGS Scaffolding and Envirowrap respectively. A manned safety boat was supplied by Kier for all scaffold erection and dismantling works.
All personnel were ICATS accredited and held the requisite blaster, sprayer and supervisor additional module certifications. Regular site inspections were carried out by the NACE and ICORR accredited contracts manager and HSQ&E officers conducted a series of site audits to confirm adherence to our safe methods of working, risk assessments and COSHH assessments.
We produced an Environmental Risk Plan and Impact Assessment, which highlighted the main environmental issues Jack Tighe Ltd had to encounter during the grit blast removal of existing paint coatings and the reapplication of new coatings. The main issues identified include: –
Airborne Dust – All grit blasting works took place in an enclosed encapsulation area to minimise the escape of airborne dust.
Land Contamination – To prevent any discharge to land from equipment, drip trays were placed under all static plant and under bowsers when refuelling. All paint materials were locked securely in a bunded paint store.
Noise – All engined plant was hired from reputable Uk companies and were fitted with silencers and turned off when not in use.
Waste Disposal – Waste grit was disposed of in an enclosed skip and a sample sent away to Oemachem Testing Services for analysis to determine whether it was classed as hazardous waste. We then arranged for the relevant waste carrier to dispose of to the correct landfill site.
During the project, the bridge was closed to all traffic, but remained open to pedestrians and cyclists. Motorists were diverted via Metheringham, Woodhall Spa and Horncastle.
Phase one of the project involved blasting and painting 50% of the underside of the bridge and 100% of the parapets, this allowed the road to be re-opened and available for civils works at an earlier stage therefore reducing the closure period. Phase two allowed us to complete the remaining 50% of the underside of the bridge.
Heavy rainfall in mid-June caused the River Witham to rise to an unsafe level for work to continue and the flood risk in place delayed work by four days (12th, 13th, 14th, 17th June). Consequently, we worked closely with Kier Services and all other parties to work additional shifts and catch up on lost time.
From Steve Rudkin (Kier Programme Manager): –
“I would like to thank all those involved in planning, delivering and managing the works, despite the weather doing its bit to disrupt things, we substantially completed all key tasks and met the original completion/road opening date. The organisation and co-operation between all parties has been first class and it has been a pleasure to work with the teams concerned. Bardney bridge has been given a new lease of life and feedback from locals on the way site personnel conducted themselves and carried out the work has been very positive.”
The work was completed towards the end of June 2019 at a cost of circa £215,000.
