Building Maintenance for Partington LNG Main Access Road

The National Grid Partington LNG site is a liquefied natural gas storage site. The site is high security with strict safety procedures. It has a high volume of heavy traffic that meant the current road surface had become worn and had suffered badly from frost damage.

Bagnalls were appointed to project manage the road renewal project, as a UVDB Verify contractor. The works were to plane and remove the existing surface to 50mm, clean and prepare the area, apply K140 tack coat, supply and machine lay 10mm SMA wearing course 50mm thick, roll and consolidate. There was also work to gully covers and frames, concrete kerb channels and 70mm base course to defective areas.

Traffic management involved traffic lights, pedestrian footpaths, crossover points and close co-ordination of all machinery. This allowed us to carry out the preparation work in 2 sections and cause the least amount of disturbance to National Grid. The final machine lay of the wearing course however meant that the whole road had to be closed. This was started and completed on a Saturday to minimise disruption. A secondary entrance to site was opened, as arranged with National Grid, to allow any site traffic/emergency access.

Health & safety was at the forefront of the project, permits were issued after submission of the comprehensive method statement and risk assessment into which all of the operatives and supervisors were inducted. They were also inducted into the site rules and procedures, which are very strict for a natural gas site, for example, no use of any electrical equipment or mobile phones and the use of fire retardant overalls. The operatives are trained to CPCS or NPORS standards on the specialist plant and machinery; they also hold NVQ Level 2 in using the equipment.

National Grid personnel were impressed with the quality of the work and visited the work 2-3 times a day. The site was constantly monitored by the Bagnalls technical support personnel who also checked quality and method of working. Overall, the work took 4 days to complete with the operatives working long days to ensure that the work caused the least interference with National Grid.
