Our Construction Projects in Ottawa

This project required lifting and positioning a 40-ft long, 8-ft wide, 8-ft high unit weighing 16,000 lbs into a tight space with extremely limited headroom between the crane hook and roof structure. Our team engineered the lift plan, coordinated rigging, and safely hoisted the equipment 250 feet into position with precision placement.

At Rego Construction Group, we specialize in complex hoisting and rigging operations, handling challenging lifts where space, weight, and safety requirements demand expert planning and execution. 

This project required a full mechanical demolition under an aggressive six-day deadline. The scope included the removal of all existing plumbing and HVAC systems, including piping, electrical wiring, 22 ceiling-mounted cooling units, three rooftop condensers, and 12 compressors.

Through careful coordination and the exceptional dedication of our crew, we significantly exceeded expectations—completing the entire demolition in just three 12-hour shifts.

Our team executed the work efficiently while maintaining strict safety standards and minimizing disruption, demonstrating our ability to deliver high-quality results under tight timelines.

 We began by preparing the excavation for a modified concrete pad designed to support a cooling tower system. The site presented challenging subgrade conditions, consisting of dense blue clay, which made achieving the required 98% compaction particularly difficult.

To address this, we over-excavated an additional foot of clay and replaced it with layered 4-inch stone wrapped in filter cloth, building up a stable 3-foot sub-base. This process ensured a solid and reliable foundation for the structure.

Following successful compaction testing of both sub-base and base materials, we progressed to forming the main pad with integrated piers. These were engineered to support the steel framework of the cooling tower. The design included high-load rigid insulation beneath the 12-inch slab, along with columns reinforced by a dense double rebar mat—providing long-term structural stability and resistance to shifting.

Once the pad was poured, it was carefully tarped and heated to meet required curing conditions and pass concrete strength tests. With the foundation in place, we moved on to forming and pouring the structural columns.

Despite encountering unexpected challenges, our team remained committed to maintaining the project schedule. Through dedication, including weekend work. We successfully advanced to the final stages, utilizing specialized equipment to assist with the precise installation and connection of the cooling tower.
