Mechanical contractors: Who are they and what are their responsibilities?

Mechanical contractors are those responsible for overseeing mechanical projects. They are in charge of the building’s heating, cooling and plumbing systems. Some other contractors also manage maintenance and repair for buildings throughout their lifespan. To better understand the scope of work of these contractors, let’s take a look at some typical mechanical items in a building or structure:

  • HVAC system: Heating, ventilating, air-conditioning equipment.
  • Cooling system: artificial cooling by transferring heat around or moving heat from one area to another.
  • Plumbing: Pipes, tanks, fittings… control the process of water supply, heating, and sanitation.
  • Power system: The electricity supply network, distribution, and use, including overhead and underground lines, power poles, transformers…

  • Project human resource management
  • Task assignment to team members
  • Design mechanical parts, then perform the on-site installation using VDC/BIM solutions
  • Monitor construction resources such as equipment, materials…
  • Supervision of electrical construction and maintenance scope

In a large project, mechanical contractors will coordinate with many contractors in charge of other jobs to accomplish a final goal. They must also ensure that the work is completed within the deadline and budget specified in the contract.

3 criteria to choose a high-quality and suitable mechanical contractor for your project

1. Licensing and InsuranceYou need to find a qualified mechanical contractor, especially when working with an HVAC system, as it can be costly. A trustworthy company should have a full license and corresponding insurance, and this information is usually published on the contractor’s website. If not, you need to ask them to show it to you when discussing it in person.2. Online reviews from their previous clientsThe Internet is a great resource whenever you need to find information and quality reviews of contractors. However, consult selectively and multi-dimensionally; Pay special attention to the comments of customers who have many similarities with you (about the project, budget, time, type of work…)3. Financing or leasing offersAs mentioned above, mechanical items and parts like HVAC are often costly. Therefore, you can prioritize mechanical contractors who can offer reasonable prices, financial support, or mechanical leasing policies. Thus, you can reduce the financial burden on your projects, especially large-scale projects.mechanical contractor vivablast thumbnail-min
