As you are aware, during the submittal process, NSF 61 compliant admixtures were requested be utilized on the project. The contract documents did not refer to an NSF requirement and the request to supply NSF approved admixtures led to additional costs incurred for the supply of concrete. Transmit Mix, our Concrete supplier, has passed on his increased cost for the admixtures at five dollars per cubic yard. A breakdown of the concrete mixes and quantities used is attached. Also attached is the formal Change Order recapitulation sheet. The total for the change order results in an increase to contract amount of $10,252.00. Please submit these costs to the engineer.
