Industry Code: 34800
This industry describes batch plant mixing activity and the transportation and delivery of concrete by truck.
Operation Details:
Transit mix describes concrete which is wholly or mainly mixed in truck mixers while in transit to the job site. Some businesses operate a concrete batch plant, other businesses may operate only transit mixers (commonly referred to as ‘cement trucks’), other businesses operate batch plants and trucks, which is the intent of this classification.
A batch plant or mixing plant features hoppers in which cement, aggregate (crushed rock/sand) and binding materials are individually placed. Dependent on the specification or type of concrete desired, the material is mixed with water in a large batcher tank, and monitored by computer from a nearby control room. Transit mix trucks drive under the batcher, and with the operator watching from the control room, the concrete batch is automatically deposited into the mixing drum on the truck. By weight or amount, the truck is loaded and signaled out from underneath the batcher.
Specifications for the concrete batch mix can vary: from top quality materials used in construction, to lesser quality for residential driveways. The distance from the batch plant to the job site is also a factor which predetermines the amount of water content in the mix.
The larger transit mix businesses also operate concrete pumping trucks to facilitate the unloading of the concrete from the transit mixer, particularly in areas and job sites that are not easily accessible by the trucks. The concrete is unloaded from the transit mixer into a hopper on the concrete pumper, and pumped through a flexible tubing system to the job.
Businesses may operate a batch plant, trucks, and maintain a facility for repairs or service to plant components or the trucks. Businesses may utilize drivers, mechanics, technical staff, plant operators, laborers, sales/estimators, office and administrative staff.
All employers in this industry are members of the Alberta Construction Safety Association (ACSA). Safety associations represent the interests of employers and promote workplace safety through education and other initiatives. Improved workplace safety can result in fewer claims and help lower premiums. A portion of premiums collected is allocated to the association to support these initiatives.
Underwriting Considerations:
Businesses which provide concrete pumping services only are in this industry. Batch plant/transit mix businesses do not finish concrete, which is described under industry 42104; nor do they manufacture precast concrete product, which is classified in industry 34700.
