Case study: Term maintenance drainage work

Brief description:

Liaising with Knowsley Council, the utility companies, and the emergency services, King Construction acted promptly and worked 24 hours around the clock assisting in helping to clear the flood and the mess created within the surrounding area.

It was no easy feat as there was already a downpour of torrential rain placing a strain on the will and resources of our work teams who were assisting in the clear up.

Once the high pressure water main had been turned off, to put further strain on the incident the utility company was having difficulty obtaining an excavator. Without an excavator an investigation of what had caused the flood could not be established. This would hinder the process of carrying out the necessary repairs and cause further disruption to the already suffering residents.

Recognising the importance of the situation, our Operations Director reshuffled our work teams so that one of our excavators and a work team could assist the utility company to carry out the much needed investigation.

Once the investigation had been carried out and the cause established, the high pressure water main was then repaired and King Construction were the contractor employed to reconstruct the surrounding carriageway and footways, to the specification of Knowsley Council. Our drainage team also de-silted the surrounding drainage to ensure there was no blockages that would once again cause flooding within the area.

Due to the damage caused to the road foundations Merseyside Engineers Laboratory Services had to carry out various CBR tests to find out the strength of the sub grade, the existing sub grade was then excavated out until sub grade of the correct strength could be constructed upon.

The area was excavated down to 1.5 metres deep by approximately 200m2 with 700 ton of excavated material being taken away to be recycled.

Due to the works being in close proximity to the busy A57, specialised traffic management was set out to create a safe work area for our workforce to carry out the works.

Achievements against targets:

The works were completed within a five week timescale with minimum fuss to the residents.
