Project Details
Description
The works are required to maintain the safety and integrity of the A90 carriageway Laurencekirk Bypass. Numerous accidents have been recorded in this area dating back to 2017 in relation to wet/damp conditions. The works will improve the road user experience by improving the drainage and negating any future ponding/flooding in this location.
The work will involve the remediation and replacement of damaged pipework within filter drains, the relocation of existing manholes within the running lanes at junctions and the renewal and widening of existing filter drains. Works are to be carried out within both the Northbound (NB) and Southbound (SB) verges, central reserve and junctions.
The following plant and machinery will be required:
- Tipper truck;
- Excavator;
- Grab machine;
- Sweeper; and
- Hand tools.
The following materials will include:
- Filter material;
- PVC pipes;
- Pre-cast concrete manholes;
- Site mixed concrete;
- Vehicle fuel;
- Lubricant; and
The total area of works is approximately 69,636m2 (6.9ha) across both sides of the dual carriageway and its associated verges.
The proposed construction is programmed to be undertaken within the 2026/2027 financial year for a duration of approximately three months and overnight working will be required.
Traffic Management (TM) in the form of alternating single lane closures will be utilised throughout the scheme. Junction closures and diversions will be used where works are located within 50m of junctions.
Location
The works are located on the A90 carriageway just outside Laurencekirk, Aberdeenshire over an area of approx. 69,636m2 with the National Grid References (NGR) detailed below. The scheme location is also illustrated below in Figure 1.
