As a partner on your projects, we always want to make sure we provide the value you are looking for. Part of that value is providing your team with a pre-installation plan for how we will install precast components in a way that makes the most sense for your jobsite.
Pre-planning for a precast installation starts during the preconstruction stage of a project, but really takes off once we are awarded the job. The successful completion of the precast install is largely based off of a well-executed installation plan that takes into account safety, trucking access and staging, crane placement and obstructions, and an agreed upon strategy between the precaster and general contractor for the sequence of the erection.
First and foremost, all plans need to take safety into account. Leading edge (the unprotected side and edge of a floor, roof, or formwork for a floor or other walking/working surface), working at heights, crane safety, and other subcontractors on site are all unique parts of the precast install. Taking these items into consideration early on and developing feasible solutions to accommodate them will jump start a successful precast erection.
One of the keys to success is pieces installed per day. The more pieces available to be readily installed reduces the amount of time the precaster is on site, a win-win for all parties involved. Getting the trucks transporting the precast pieces to the crane on site quickly and efficiently eliminates crane downtime (inactivity) and accelerates precast completion.
Another key is crane placement and obstructions. Does inside access with a smaller, more mobile crane suit the site conditions better or a larger, less mobile crane on the outside? Many factors go into this decision including price, completion of other subcontractor work (providing a hold out for crane access), truck access, and site obstructions/limitations. As your partner, we provide a crane map with our suggestions based on your jobsite and size needs for your precast.
The final key to a successful precast install is an agreed upon erection sequence between the precaster and the general contractor. Future work of other subcontractors, site restrictions, and the three items listed above (safety, trucking, and crane) all go into this decision.
The main goal is to successfully install all precast members in the most efficient and safe manner so as to use a minimal amount of time to complete. Taking these items into account will help determine the best path for all parties involved, including the owner, general contractor, precaster, and other subcontractors. A solid and well thought out pre-plan for precast erection will start any job out on the right foot and will pay dividends later.
