Balfour Beatty Construction Value: £2.9m Start date: January 2015 Contract length: 18 months


"I have worked with Addison Plant Ltd on and off for 20 years and recently completed a public realm scheme in regenerating Stockton High St. This was a two year project upgrading the bus routes and hard landscaping.
I was very impressed with APL’s attitude regarding safety and their consideration to the public as this is a busy High St with events been held throughout the year. The safe digging practices employed resulted in zero service strikes which is highly commendable due to the complex network of services and underground tanks/cellars encountered.
The works consisted of drainage, ducting, earthworks and street furniture with the value of circa £3m and a large number of site operatives at any one time."

PROJECT SUMMARY The proposal of the A1 Coal House to Metro Centre scheme was to increase the lane capacity of 4 miles of the A1 in each direction. The scheme was built within the existing highway boundary and cost in the region of £60 million. The scope of our work was to install a new surface water network to service the new road layout discharging into existing outfalls. The new network ranged from pipes 150mm diameter to twin 900s. Numerous hydrobrake chambers were required, the biggest being 3m in diameter. Limited working room was available in the existing verges which made the job particularly challenging. A full time distribution gang was required to distribute plant and materials across the site. Our contract included the supply of all aggregates and also the disposal of excavated material off site. Whilst carrying out the new drainage installation Addison Plant were also given an order to rectify a long list of defects to the existing network. This was done by a variety of methods, dig down and repair where possible or carry out remote patch repair where there were access issues. Where the existing pipes were badly damaged an Ultracoat system was used to repair and reinforce the pipe. The majority of the work was carried out during day shifts with the remaining works including drainage crossings to main line carried out at night.
