Pre-engineered steel Einreichplan and metal buildings are cost-effective in commercial applications. Developers and property owners can save money by using these structures for new and retrofit construction. Construction schedules can be significantly compressed by project managers, which results in a reduction in overhead for contractors and any downtime that could affect the tenant of a retrofit or new building.
Pre-construction costs associated with traditional buildings can be high due to the amount of project management required to compile bids, and submit pricing items. These wood-based construction methods require a lot of time. Concrete block structures can reduce pre-construction times slightly, but the coordination of continuous inspections and pricing requires project management that is almost nonexistent with steel buildings.
Project management is required to ensure that each subcontractor has a contract. Steel buildings can eliminate many of these project management expenses, as the fabrication includes framing, roofing and window and door installation within the scope. The initial activities on-site can be started once the contracts have been signed and approved.
The first step in generating construction plans for commercial projects is to create a design that suits the intended use of each building. Even simple structures like a storage building or service building require approval plans with structural engineering and mechanical engineering to get permits. The costs of mechanical engineering and architectural fees can be very high for conventional systems.
Fabricators of steel buildings can offer pre-approved designs without the need for architectural involvement and building department plan approval. Pre-engineered building projects require plans, permit check and plan approval. Most often, the mechanical trades and concrete foundation are all that is required. For all new commercial buildings, the initial on-site activities such as footing excavations or the installation of underground utilities, are the same as for steel buildings. This phase often results in cost savings by avoiding the need for extensive footings and structural pads that are required to support concrete block load-bearing walls and wood frames.
Pre-engineered metal buildings use steel I-beams with clear span headers and internal vertical support columns. This eliminates the need to use wood or poured-in-place concrete support systems, which are significantly heavier and take longer to install. Steel web trusses can be used for roof support. This is far faster than wood trusses and panelized roofs in terms of installation time.
Additionally, sheet metal siding and roofing have lighter loads than metal roofing which will result in a smaller concrete footing. This results in a significant reduction of costs associated with concrete footing materials and man-hours as well as footing excavation, hauling of spoils and footing cleanup. Construction can be completed in less time by eliminating the need to use conventional structural systems and related activities. This reduces general contractor overhead costs.
It is much simpler than typical residential or commercial construction to erect steel buildings on-site. After the concrete footings have been set and the underground stub-ups have been installed, the structural components can be transported to the site and offloaded. The construction can then proceed without any interruption. This assembly allows for the installation of electrical circuits, plumbing connections, and air conditioning units without the need to coordinate with the job site supervisor.
Additional equipment and systems such as compressors, lifts, or pressurized air lines, can be installed easily without causing any inconvenience to the vendors. This allows for a clear definition and coordination of these installations. The contractor’s involvement is usually reduced to a fraction of what it would normally take to supervise these activities.
The cost of construction of commercial buildings is also reduced by reducing off-site activities. Roll-off dumpsters do not require monthly street permits because there is so little debris involved in steel building construction. Over the entire project, additional permits are not required for material drops or traffic control. There are no inconveniences to neighbors such as the need to use pumping equipment to apply stucco or kettles for hot roofing.
