Building a commercial building is a complex process that involves multiple stages, various professionals, and key permits. The process can take anywhere from several months to well over a year, depending on the size and complexity of the project. Here is a general overview of the steps involved in commercial construction:


Pre-Construction Phase

During this lengthy and important phase, the owner works with the architect and the general contractor to determine the goals and requirements for the project. This phase also includes site selection, determining the best location for the building based on factors such as accessibility, zoning regulations, and environmental concerns.


Feasibility studies are also conducted to determine if the proposed project is viable and if it is financially feasible. The architect also works with the owner to conceptualize the building’s design. Once the final design is approved, the architect creates detailed drawings and specifications for the new or remodel construction project.


Lastly, this phase involves obtaining all necessary permits and zoning approvals from local government agencies. The general contractor will assist the owner in securing planning, building, fire, and health department permits. Building permits are necessary to ensure that the project meets all codes and safety regulations. Environmental permits may also be required to meet air and water quality standards. Other approvals as required by state or federal laws include hazardous materials, stormwater runoff, or erosion control permits.


During Construction Phase

This phase includes site preparation, which contemplates clearing and grading the job site, excavating the foundation, and preparing the area for construction. This may also involve installing temporary utilities, such as water, electricity, and gas. Site preparation is critical as it ensures that the building’s foundation is built on a solid and level surface.

A key milestone in the construction phase is pouring the building’s foundation. The foundation is the most critical component of the construction process, and it must be designed and constructed to withstand the weight of the building and the forces of nature, like earthquakes and high winds.


During this phase, the building’s structural elements are also installed. This may include the steel framing, concrete walls, and other structural components. In addition, the building’s enclosure is completed, which is made up of the structure’s roof, exterior walls, windows, doors, and insulation. The building enclosure should be energy-efficient and protect the interior of the building from all types of the weather.


Finally, this phase includes the installation of mechanical, electrical, and plumbing systems, drywall installation, flooring installation, painting, and the installation of exterior finishes. The interior and exterior finishing is the penultimate stage of the building’s construction, and it is critical to ensure that the building is functional, safe, and aesthetically pleasing.


Post-Construction Phase

After the actual construction is complete, the building will undergo a final inspection by local government officials to ensure that it meets all safety and building codes. The inspection process routinely includes checking the building’s electrical, mechanical, and plumbing systems, as well as ensuring that the building is accessible to people with disabilities.


Once the building has passed all inspections and approvals, it can be occupied and used for its intended purpose. The owner must maintain the building, including performing routine maintenance, repairs, and upgrades. However, a professional general contractor will warranty certain aspects of construction and will work with the owner to make sure the new or remodeled building remains safe, functional, and aesthetically pleasing for many years to come.
