Successful concrete work requires a thorough Quality Assurance/Quality Control program. VJS will work with the architects and their engineers early in the design process to assure that the concrete specifications are consistent with our lessons learned on concrete mixes and admixtures as well as means of placement. Ultimately, VJS is responsible for the final product and the early involvement of VJS helps to ensure high-quality concrete work.
Critical to the quality of concrete is the protection and curing process that takes place for some time after the pour. The advantage of having VJS pour the concrete is that VJS personnel are on-site at all times and can monitor the curing process as opposed to a concrete subcontractor who may be offsite after pouring.
The concrete work can also be sporadic and is critical to the project schedule. Having VJS self-perform the concrete work decreases the chances that personnel would not be available to meet our schedule requirements. Concrete work can be highly susceptible to weather and with in-house crews performing the work we make sure that all weather-related precautions are taken and that crews are flexible when weather impacts the schedule.
VJS concrete crews have proven to be very competitive as witnessed by the fact that we are concrete subcontractors on numerous projects by means of a competitive low bid where VJS is not the construction manager.
