Paint Shop Process Waste

This automotive plant project involved combining the process waste flow from two paint shops into a common process gravity sewer system leading to the onsite waste treatment plant.

The calculated maximum combined flow was, in fact, greater than the 1900 USGPM capacity of the existing gravity sewer, which necessitated flow control measures to meter the flows. Since flows from both plants fluctuated with shift loads, storage head tanks were installed to allow the metered flow to function effectively.

Another challenge was the difference in flow velocity. The new paint shop process water was being pumped, while the process waste from the existing paint shop flowed by gravity. In order to discharge the pressure and velocity energy from the pumped process waste, a two-compartment underground concrete quiescent chamber was designed and installed between the pumped and gravity sewers. This allowed the two waste streams to mix and flow to the waste treatment plant much more effectively.

Citigroup European Headquarters

This 1.2 million ft2 facility consolidates UK and European operations for Citigroup, the world’s largest financial institution. Our project scope included a 30,000 ft2 server farm/computer centre and 42 floors of communications technology rooms, supported by six 1600 kW rotary diesel UPS units for 9.6 MW of back up power to critical operations. At the time of construction, Citigroup Tower was the third tallest building in the UK.

Rotary diesel UPS units were arranged in four systems to provide dual redundant power to critical loads, using a highly fault-tolerant distribution scheme through to the raised floor Power Distribution Units and tech rooms. A sophisticated dual redundant load management system provides for control of all critical and essential loads under all normal operating and failure mode conditions. The design was configured to expand by two more 1600 kW units, for an ultimate load capability of 12.8 MW.

The control system also permits operation of all international office functions when all diesel UPS systems are available following a utility power failure via sequenced load stepping, allowing for a “business as usual” operating scenario even under widespread utility outages.

Woodbine Entertainment Group

Mohawk Racetrack

Woodbine Entertainment Group (WEG) is a longstanding and valued client, dating back to the late 1980s. Through our successes at Woodbine over the years, and the development of a strong relationship, we are privileged to fulfill the role of trusted advisor.

Mohawk Racetrack is a Canadian racetrack for Standardbred horse racing programs, owned by WEG, (formerly the Ontario Jockey Club).

At the Mohawk site, we engineered the addition of a 1250kW diesel generator and associated distribution equipment, which provides complete backup emergency power, plus redundant back up emergency power to the Slots floor.

HH Angus was also responsible for providing upgrades and new construction for the grandstand, including a new grandstand enclosure, M&E upgrades to the kitchens, and mechanical infrastructure upgrades to the chiller and boiler systems.

Additional work included:

Racing improvements
Slots/Gaming Floor renovation and expansion
New administration area
Site lighting
Site electrical distribution upgrades
Mechanical upgrades to chiller/boiler systems

Plant Additions

HH Angus has served as the Prime Consultant for a variety of automotive plant additions and renovations for General Motors. These are three of many projects for this valued client.

C/K* Truck Plant

HH Angus coordinated the 1,800,000 ft2 addition to both the building and building services for the new modular paint shop, body shop, paint oven enclosure and elpo phosphate process.

This project included the installation of three 633-ton chillers and one 250-ton chiller for building and process chilled water loads.

* C/K: C indicates 2-wheel drive trucks and K refers to 4-wheel drive.

GMT 800 Oshawa Truck Plant

This was a 300,000 ft2 addition to the existing C/K Truck Plant in Oshawa. Our project scope included coordinating architectural and structural design, mechanical/electrical design, and contract administration. The building is a 35 foot high, single-storey structure with insulated metal siding and 42,000 ft2 mezzanines with washrooms and one mezzanine for the welder water system. The project included a new 8,000 ft2 room and a quality measurement laboratory. The project included electrical bus duct distribution to process loads, as well as a quadruple-ended paralleled welding distribution system for welding robots.

Renovations to C/K Truck Plant

This project consisted of a four-bay addition with four levels to the existing paint shop facility at the Oshawa Truck Plant to house a new primer surfacer spray booth, accumulator conveyor, prep booth, freight elevator, storage, clean room and all associated building services.

Canadian Museum Construction Corp.

National Art Gallery of Canada

We are very proud of our contribution to Canada’s National Gallery, one of the country’s landmark institutions.

This project consisted of two buildings: the Gallery building of 549,000 ft2 and an administration building of ~54,000 ft2. The Gallery building houses Canada’s national art collection in state-of-the-art environmental conditions, with close control of temperature, humidity and high efficiency air filtration.

Each gallery has individual control of its environment, and high levels of humidity are maintained year round. Air with low of humidity levels is supplied to public circulation areas, such as the colonnade, galleria and Great Hall, to prevent migration of humidity from the art display galleries. Such migration could cause condensation on the large areas of exterior glass that enclose the building during the cold Ottawa winters.

In addition to the public galleries, administration offices and cafeteria, there are restoration workshops, authenticity and verification laboratories, paint and varnish shops, photograph storage, and fine art storage areas. A 200-car underground parking garage and loading dock were also incorporated.

The low-rise design of this gallery involved stairways and ramps as features, which eased the requirements for passenger elevators. Freight requirements, on the other hand, required large units for the movement of exhibits, with the doors of these elevators measuring up to 12’8” wide by 12’0” high.
