Frequently Asked Questions

  • Mechanical estimating is the process of calculating the costs, materials, and labour needed to complete mechanical systems in a construction project. This includes HVAC (heating, ventilation, and air conditioning), plumbing, and fire protection systems. Accurate mechanical estimating is essential because it ensures contractors submit competitive bids, avoid cost overruns, and keep projects on schedule.

  • We use Ensign estimating software, one of the leading platforms in the construction industry for mechanical, HVAC, and fire protection estimating. Ensign allows us to produce fast, accurate, and detailed take-offs and cost breakdowns. By using dedicated estimating software, we can deliver reliable results that help contractors stay competitive while reducing the risk of errors.

  • Yes. Our team provides specialist estimating for HVAC systems (heating, ventilation, and air conditioning) as well as fire protection systems such as sprinklers, alarms, and suppression systems. Each estimate is prepared to industry standards, ensuring compliance, safety, and cost certainty for your project. Whether it’s a small-scale installation or a large commercial development, we cover all aspects of HVAC and fire protection estimating.

  • Outsourcing mechanical estimating allows contractors and subcontractors to save time, reduce overhead, and improve bid accuracy. A specialised mechanical estimating service provides expert knowledge in HVAC and fire protection systems, uses up-to-date cost databases, and ensures that estimates are detailed and reliable. This gives contractors a competitive edge when bidding on projects.

  • Mechanical estimating services help contractors submit more accurate, detailed, and competitive bids. By focusing on HVAC and fire protection systems, estimators provide cost breakdowns that highlight potential savings and efficiency improvements. This accuracy builds trust with clients, reduces risk, and ultimately increases a contractor’s chances of winning new projects.
