Q: Do commercial contractors negotiate work?

A: Many commercial contractors negotiate a large percentage of their commercial projects.

Q: How do commercial contractors keep competitive pricing when they negotiate a contract?

A: In order to determine the negotiated price, commercial contractors solicit bids from numerous subcontractors and suppliers to ensure both the best pricing and the highest quality in materials and workmanship.

Q: What is the difference between commercial and residential construction?

A: Commercial construction has stricter building codes regarding fire protection, suppression, and ADA compliance. Commercial construction usually requires the allocation of greater financial and human resource in order to meet critical client deadlines.

Q: What is the best type of contract to use?

A: The most favorable contract is one that both the contractor and the owner of the property agree upon. That might be a fixed price, cost plus, or cost plus with a maximum. What is most important is that the commercial contractor will work to finish the project on time and within budget.

Q: Do I need architectural drawings in order to obtain a proposal?

A: This depends on the scope of work. For minor modifications or upgrades, most commercial contractors can provide an estimate based on a site inspection. However, large jobs do require drawings that detail the scope of work in order to provide a comprehensive proposal.

Q: When is the best time to choose a contractor?

A: The best time to select a contractor is at the beginning of the project. It is important that the contractor is able to participate in discussions in order to ensure clear communication of important information.

Q: What is the best time of year to build?

A: Spring and fall are typically the best times of year to build. The heat of the summer often causes workers to tire more quickly. Winter weather also creates unique challenges to construction teams.

Q: Can a commercial contractor help in the design of a building in order to save money?

A: A commercial contractor can offer suggestions during the design process as well as answer questions regarding feasibility and expenses of certain design elements. But with that said, state law prohibits contractors from acting as designers unless they have a licensed architect on their staff.

Q: If the commercial contractor hires subcontractors, how can I be assured that the subcontractors will produce quality work?

A: Be sure that the commercial contractor whom you hire will make it right if the subcontractor’s work does not meet the high standards of you, the customer.
