A concrete brief should state structural element, project standard, exposure, target strength, workability, maximum aggregate size and placement schedule. Pump distance, temperature, transit time and site access affect mix and production planning.
Special performance needs are confirmed through laboratory design, trial production and site quality planning. Agree sampling, test age, acceptance tolerance and curing method in the inquiry or specification.
What to include in the inquiry
- Concrete class, exposure and governing standard
- Workability, aggregate size and pumping method
- Placement volume, schedule and site access
- Sampling, test age and acceptance criteria
