Construction Heating Case Study: High-Rise Construction

The Challenge

A multi-story construction project in a major city had more than sixty floors requiring a dependable heating solution to stay on schedule. Sixteen floors in the middle of the building needed reliable heating for concrete curing and worker comfort. The building had no provisions for receiving natural gas through risers. It also lacked facilities to provide temporary power, therefore running electric heaters was not an option.

City laws prevented the contractor from using propane-based heaters due to their hazardous nature and risk of explosion. Regulations dictated that carbon monoxide emissions be less than 50 ppm.

The Solution

With sixteen floors requiring critical heat on a multi-million-dollar project heavily constrained by time, Cahill offered the perfect solution. The contractor rented four of Cahill’s JetHeat GT1400 flameless heaters to have each heater heat multiple floors. These industrial heaters were able to distribute heat evenly through each floor by running temporary trunk lines and split ducting.

As the project progressed smoothly, the contractor faced another challenge – a few remote areas of the large construction project needed heat for surface preparation, painting, and drying excess moisture. Needing localized heat, the contractor decided to rent Cahill’s extremely portable standalone JetHeat GT1400 heaters. Small and durable, the contractor could easily move these flameless heaters through doorways to heat remote areas of the site, efficiently providing clean, breathable dry air.

Results

At a time when the coldest winter temperatures were recorded during the construction of this project, Cahill delivered the necessary temporary heat to continue the project without delays.

Cahill’s industrial heaters helped the contractor decrease downtime, increase worker productivity, and avoid contractual penalties. Needing no external power source and being capable of replacing multiple heaters using split ductwork, Cahill’s JetHeat provided the best option.
