Wednesday, 20 September 2017, Kuching: While it is incumbent upon LBU, the Project Delivery Partner, together with main contractors of the Pan Borneo Highway Sarawak to complete the project on time and within the allocated budget, maintaining the existing construction stretch is also of utmost priority to ensure smooth and safe drive for road users.
These routine maintenance works include grass cutting, pavement and drainage maintenance, road furniture maintenance as well as bridge and culverts maintenance, amongst others.
Take grass cutting for instance - it should be carried out once a month at the road shoulder, slope area, berm drain, interceptor drain and all types of drain on slopes.
Pavement maintenance has to be carried out too. This includes potholes patching, sealing of surface cracks, reinstating of edge deterioration of back filled trenches and treatment to stripping of aggregate.
A case in point is the dislodged precast slab panel for a temporary bridge, 3km from Saratok junction towards Sarikei under the Sungai Awik Bridge to Bintangor Junction (SAB) works package which happened at last weekend.
The project team rushed to the site and got it rectified in less than three hours, despite the rain that Sunday evening.
Another example to show how frequent such road maintenance works that have been carried out is the Sungai Arip Bridge to Bintulu Airport Junction (ABJ) works package.
In the month of August alone, ABJ had carried out pothole patching in 55 locations with a surface area of 463.09m2 starting from Ch. 0+000 to Ch. 66+281.
ABJ main contractor, KKB-WCT JV, had also cleaned and cleared debris along 1,830m of concrete roadside drain under the works package.
A total of 72 signages had been repaired and maintained along the construction stretch while three bridge expansion joints were maintained last month.
The above are just some of the examples of how each WPC is dutifully carrying out road maintenance works, on top of the highway construction works.
Road maintenance is necessary to ensure safe road conditions for road-users while waiting for completion of the much-awaited Pan Borneo Highway Sarawak by 2021.
