Project Details
BEAR Scotland has been commissioned by Transport Scotland to carry out road drainage works along the A82 trunk road. The culvert 1 carrier pipe (refer to Figure 1) has been identified to be severely damaged and is not repairable. The works propose to fill the culvert 1 and divert the water from the waterbody 1 to the culvert 2 which has the capacity for extra water flow.
The works will include the following activities:
- Blocking off the damaged culvert 1 (see Figure 1) either side of the A82 carriageway.
- Fill the voids within the culvert 1 with concrete.
- Excavate a new ditch along a southbound of the A82 in order to divert the Waterbody 1 (see Figure 1) water away from the damaged culvert 1 to a culvert 2 (see Figure 1). Excavated earth material is to be site casted within the road verge.
The culvert 1 carrier pipe was found to be defective during a drainage investigation. The defective culvert carrier pipe is at risk of further collapse which could in turn close the A82 Trunk Road.
The total length of the scheme is 100m with an approximate area of 0.061ha.
The main plant will include excavator, tipper, Hiab and welfare van. A welfare unit will be located within on the A82 within the traffic management (TM) setting.
The works are programmed to be completed within the 2025/2026 financial year, currently aiming for commencement in May 2025, however this is subject to change. Works will be undertaken during day-time hours (07:00-19:00) over the duration of up to 3 weeks.
TM will consist of a single lane closure with 2-way temporary traffic lights (TTLs). Pedestrian access will be maintained. If the programme changes, this may result in amendments to the exact TM requirements.
