THE scheduled commissioning of the refurbished Savusavu Buca Bay highway next month maybe put on hold as the contract progress is slower in areas along the stretch.
Authority CEO Neil Cook said the Fiji Roads Authority was seeking to ensure quality aggregate gravel for the project.
Mr Cook said they were seeking gravel good enough to provide them with the road design like they were looking for.
He added that they wanted value for money from every Fiji dollar invested into the project and by applying effort at every stage of design and construction it could ensure that they built a road that is fit for purpose and will achieve what they wanted it to achieve over its life span.
"Good quality aggregate is a key component to achieving a pavement with durability and strength," he said.
"FRA, contractors and our consultants are working through some very technical investigations to determine ways in which we can work with the materials that are available without compromising the long-term sustainability of the road network.
"There are similar issues elsewhere in Fiji and these challenges are all part of the journey towards not only a sustainable road network but also a sustainable road building and maintenance industry that includes suppliers of raw materials, contractors, designers, construction supervisors, materials testing services and more contributors."
Mr Cook added that the natural rock on parts of Vanua Levu did not meet some of the key quality standards or characteristics for supplying quality gravel and that this needed to be resolved satisfactorily to ensure that the roads last.
