The Well Design

“The Well” Diffuser

Design of underground diffuser; two ∅35′ diameter disk and 135 ft high. All shipped in small pieces to site and assembled with minimal welding.

About this Project

Downtown Toronto is heated and cooled with a thermal fluid.  “The Well” allows the fluid to be stored as well as regulate or control the fluid temperture. It is located in a cavern beneath a high-rise building in Toronto.

The Diffuer’s are ∅35′ in diameter and 135 ft high with ∅24′ piping, all fabricated off site and bolted together in the cavern.  Temperature reversed of up to 100° F.

1500+ bolts and only 2 holes had to be opened up.  Assembly and installation took 2 weeks.

Modified tower crane sections supported the diffuser disks and additional and bracing to accommodate the lateral forces introduced by thermal expansion of the supply & return pipes. Objective Engineering designed unique horizontal bracing  joints and connections to properly distribute the extra loads to prevent crushing of piping, maintain lateral stability and to easily install the bracing in a years’ time when the concrete walls will be placed.

Rooftop Crane Steel Frame and Shoring

Design, fabrication drawings and site review of a temporary steel frame and shoring for a rooftop mounted crane for use during renovation construction of a multistory building.

About this Project

Retrofitting older buildings in the tight landscape of Toronto requires equipment to be lifted to the roofs of large buildings with minimal impact on traffic flow and road closures.  To overcome this issue, our client mounts cranes on the rooftop for use during construction.  Equipment can then be raised without using a road crane that would block traffic for extended periods of time.

Our role was to design a structural steel support frame to mount the crane (Terex CDK 100-16) and design the shoring to safely support the crane and loads on the existing building structure.  The steel frame is designed in modular sections that can be brought up through the existing building or hoisted with a swing hoist and assembled on the rooftop using bolts. The crane is assembled and attached to the frame and the frame is attached to the building.

The shoring is installed below the steel frame contact points and distributes the load over a larger surface area to prevent damage to the building. Steel posts were used as the shoring support in conjunction with steel plates and threaded bars to hold them in place. The thread bar anchors are an actively tensioned anchor system which minimize or eliminate deformations.
