Hi
Contractor question, we’re undertaking some tarmac surfacing works on a D&B contract. Our CPs at tender clarified we’d be using an SMA product to do the final wearing course. These were accepted by our client and nothing contra to its use can be found in the ERs
SMA is a regularly used product for the use case, our supply chain are happy to warrant it’s performance.
However the issue has arisen that the Novated engineer is unwilling to specify SMA as they believe it unsuitable and would prefer a polymer modified ‘named brand’ binder SMA. In our view a definite upgrade in performance and specification.
However the client is unwilling to instruct this as a change, possibly because there is a cost implication. And out Novated engineer unwilling to note the SMA on their detail design drawings compliant with out CPs.
Feels like we’re a bit stuck. Is there a way around? We’ve suggested alternative hot rolled solutions but nothing seem to budge the log jam.
Thanks
