Acting as Principal Contractor, Knights Construction’s Civil Engineering division were contracted to repair the collapsed river wall at the iconic Royal Hotel for a private client.
Work began during the summer of this year, with installation of a concrete foundation slab to support a working platform for a tower crane.
Once vegetation was cleared, Knights Construction operatives were able to operate the crane to access the work area and large sand bags were placed into the river to stem the flow of water and protect works from rising river levels.
Loose material was removed from the wall and river bed and in conjunction with a structural engineer, a solution was developed which included constructing a 60m section of reinforced concrete foundation and retaining wall, including under-pinning sections of the existing wall. These were anchored into the underlying bed-rock, and In total 120m3 of self-compacting concrete was poured into the retaining structure.
The works were completed in 14 weeks and all in close collaboration with the Local Authority, Conservation Officers, CADW and NRW. The completed wall ensures the stability of the embankment, and paves the way for the refurbishment of the Royal Hotel – Knights Construction’s Build Division’s upcoming project.
The team were praised by the client for their excellent work in an extremely difficult environment.
