Bankers Hall was completed and opened for business in 1989 and is located on the South side of Eight Avenue S.W. between Second and Third Street within the Downtown core.
This very modern complex, consists of Bankers Hall East Tower that is 195 meters (645 ft) tall with 50 stories including 41 office floors, 3 levels of retail space in class "A" environment, 6 levels of underground parking with 959 stalls including Royal Bank and 3rd street parkade and Royal Bank Tower, totalling approximately 2.2 mill square feet.
It has three +15 connections: South connection to Gulf Canada, West connection to 3rd Street Parkade, and North connection to TD Square. Within 2 block radius we will find 35 Bus routes and LRT one block away from Bankers Hall.

STRUCTURAL DESCRIPTION:
The structure of Bankers Hall is reinforced concrete with each (East complete and West future) tower founded on a 9 foot thick reinforced concrete foundation.
The structural foot print covers an area of approximately 42, 000 sq.ft.
Steel reinforcing within the suspended parkade slabs are protected with an epoxy coating and contain specific concrete mixes which eliminate chlorides commonly found in cement.
All parkade decks and slabs have been protected with Kelmar waterproofing membrane and traffic bearing surfaces to prevent structural deterioration.
The ground water table is controlled in the immediate vicinity of the parkade by de-watering pumps. They run 24 hours a day and as the level increases, water is diverted to storm drains by pneumatic modulating control valves.
A typical office tower floor plan covers approximately 23,000 sq.ft. of area and is designed to support a live load of 50 lbs/sq.ft. and dead load of 25 lbs/sq.ft.

MECHANICAL SYSTEMS.
The Bankers Hall heating plant consists of two - 500 hp Cleaver Brooks packaged boilers with full load output of 16 737 500 BTU/hr, and two - 200 hp Cleaver Brooks packaged boilers with full load output of 6 695 500 BTU/hr each. They are gas fired, low pressure , 4-pass fire tube boilers producing steam for various glycol and hot water converters.
This complex has three steam to glycol exchangers that provide the glycol primarily to "preheat" coils located in air handling systems, two steam to water exchangers that provide hot water to "reheat" coils in air handling systems and three steam to water exchangers that provide hot water for podium perimeter radiation, force flow heaters and fan coils.
Steam condensate is collected into four receiver tanks before being pumped to main steam injected condensate. It is reheated before entering the scrubber of the de-aerator and from deaerator distributed to the boilers as a feed water closing the condensate loop.
Cooling for the Bankers Hall complex is provided by two-750 ton heat recovery Trane Centrifugal, low pressure R-11 chillers, one-750 ton chiller and one - 600 ton Trane Centrifugal low pressure R - 11 chiller.
The chillers produce a 9 degree Celsius primary chilled water which in turn is pumped to various shell and tube exchangers where it is converted to 13 degree Celsius secondary chilled water and distributed to induction units cooling coils at typical floor perimeters and to retail fan coils located within tenant spaces.
Primary chilled water is also pumped throughout the Bankers Hall tower to primary coils of the compartmental fans to provide cooling for typical office tower floor interior zones.
Humidification within the Bankers Hall is provided by duct type steam injection humidifiers installed to all main air handling systems. The humidifiers utilize process steam and operate only when the respective air system is running.

Bankers Hall Tower is divided into three exterior induction unit supply zones: low-rise, mid-rise and high-rise. Each zone is serviced by two induction air handling units serving north/east and south/east respectively.
The fresh outside air is drown in, filtered and preheated, mixed with optimum amount of return air, passed through cooling coils, humidified according to RH levels, and finely re-heated and distributed throughout the tower by dedicated induction units.
This primary air is introduced to overhead induction units with build in cooling coils that uses the secondary chilled water for final temperature control in perimeter offices.
The interior zones are served by 39 Engineered Air compartmental units on a per floor basis. These constant volume units provide cooling via build in primary chilled water coils.

Parkade ventilation is controlled by CO detectors installed throughout parkade zones. Any CO concentration of 50 ppm or greater will start the ventilation system. When the CO concentration exceeds 100 ppm and stays at that level for more than 15 min., the BAS issues alarm.

AUTOMATION NETWORK
All HVAC systems, installed in Bankers Hall , are fully automated and are monitored and controlled by the Landis & Stefa System 600 with over 2000 control points and 72 field panels. Field panels provide the termination points for the field equipment, constantly monitor, control and adjust the automation points and feed the information to the main CPU ( Central Processing Unit) and collect data on the building environment for the System 600 which performs control functions to efficiently maintain ultimate comfort for the occupants.

In 1993 Bankers Hall automation network was hooked up to our in-house, remote Central Monitoring and Control Systems to efficiently monitor, control and adjust automation points and maintain the ultimate energy savings and comfortable environment 24 hours/day.

ELECTRICAL DISTRIBUTION
The main utility power enters B-H through 25 KV preferred and alternate feeds, located in the parkade, from where it is supplied to E and W substations and transformed down to 600 volts for distribution via 3 - 2000 amp, 600 volt bus duct to low, mid and high rise areas, and 1 - 1000 amp, 600 volts bus duct that provides power to mechanical systems.
Plug in fused type bus duct tap switches provide power to typical 347/600 volts fluorescent lighting and power distribution panels. Step down transformer provide 120/208 volt receptacle power.

LIFE SAFETY AND FIRE ALARM SYSTEM
The life safety systems are designed to maintain and ensure the safety of all occupants within office, retail and public areas during emergency situations. The complex is protected by Edwards 8500 two stage fire alarm system with over 5 000 field devices that are monitored by highly trained security officers 24 hours a day.
Throughout the complex there are 18 separate smoke management systems which control over 350 supply / return / exhaust fans, dampers and pressurization fans.
The complex is fully equipped and protected by automatic sprinkler system with 216 sprinkler zones identified with water flow switches.

Standpipe system with 65mm and 38mm nozzle connection designed the way that no part of the building is more than 9m from the nozzle when attached to 45m hose.

Emergency Standby Power Plant consisting of three 16 cylinder Detroit diesel engines which drive three electric emergency generators capable of providing power for all base building life safety systems in the event of normal power supply interruption.
