For equipment, use buggies that are designed to minimize jolting of the concrete. Never permit then to run at high speeds over rough ground (especially power buggies). Use buckets large enough to handle one batch load or a multiple thereof. Don't split batches. Use round-bottom chutes with a metal inner surface. Also, shade and protect from sun and wind any long exposed chutes or belt conveyors. And carefully check concrete pumping equipment for maintenance and capacity before starting operations. As for concreting procedures, specify concrete with an air-entraining admixture for greater cohesiveness and mobility whenever there is a handling problem. Specify maximum aggregate size in relation to reinforcement concentration. And handle concrete as little as possible. Try to protect a driveway for ready mix trucks to discharge directly into forms. Don't keep the truck waiting for long periods at the job site. Don't chute concrete at an angle so steep that segregation results- or at an angle so slight that the concrete must be pushed along. Never allow concrete to free fall more than 4 feet. And finally, don't pump very high slump concrete (it will clog the lines).
