A pre-pour conference sometimes gets scuttled by busy people who think that such meetings are a waste of valuable time. In truth, pre-pour conferences are necessary, and frequently result in time savings.
WHO HOLDS A PRE-POUR CONFERENCE AND WHO ATTENDS?
A pre-pour conference should be required by the specifications. If it is not, there is no one who is traditionally responsible for calling a meeting. In such circumstances, though, the ready mixed concrete producer will probably have the greatest incentive for arranging the meeting because the topics covered will usually concentrate on three subject areas of vital interest to him: concrete inspection, jobsite sampling and testing. Participants in the meeting should include representatives of the architect and/or structural engineer, general contractor, concrete subcontractors, concrete producer and testing laboratory. Owners, construction managers, building inspectors or others who will have responsibility on the project may also be invited.
Job specifications should ideally be the instrument through which problems are avoided and the basis for resolving questions that arise. That won't be the case, however, unless all parties interpret the specifications in the same way.
WHAT SUBJECTS ARE COVERED AT PRE-POUR CONFERENCES?
Some of the topics to be discussed and questions to be answered at the meeting are:
- Concrete materials and mix design
- Inspection responsibilities
- Concrete sampling and testing requirements
- Cylinder storage and transportation
- Authority to accept or reject fresh concrete
- Distribution of test reports and criteria for accepting test results
- Testing of hardened in-place concrete
Minutes should be taken and copies distributed so there is a written record.
