SUBJECT:  Main Terminal Infrastructure Upgrades Briefing 
EXECUTIVE SUMMARY 
This project will update and upgrade the Main Terminal to ensure compliance with current life
safety and building codes. 
The existing Main Terminal was built in the 1970s, with an extension to the north added in the
1980s, and Gina Marie Lindsay Arrivals Hall added in the 2000s. Although some improvements
have been made in the Main Terminal there has not been a comprehensive renovation. T he
different sections of the Main Terminal met the building codes that were in place at the time
they were constructed. Over the last couple of decades, building codes have evolved to provide
additional safety measures. These new safety measures include fire sprinklers and smoke
control.  Projects in the Main Terminal have installed fire sprinklers in the areas the work was
completed; h owever, large areas in the Main Terminal are still deficient in multiple areas
including the following life safety systems: fire sprinklers, smoke control, fire standpipes, and
emergency exit signage. This project will bring the Main Terminal up to current code, which is
required  for  future projects in the Main Terminal to move forward, such as restroom
renovations, and replacing aging bag claim devices.
This project will update these life safety systems to current code.  In addition to updating
systems to current code, this project will also include full asbestos removal from the ceiling and
upgrade the existing emergency power system. 
BACKGROUND 
In order for the Main Terminal building to meet current code the entire building must have a
sprinkler system installed. This will involve removing the existing ceiling, abating the area, and
putting in new ceiling, and lights on ticketing, baggage claim, and the skybridge level. The
current lighting does not have lighting controls, so new lighting controls will need to be added.
Smoke control will need to be added, which will include adding exhaust fans and connecting to
emergency power. The existing emergency power is not sufficient to meet the demand of the
future smoke control system.

Meeting Date: September 22, 2020 
The existing emergency power system supports the Main Terminal; Concourses B, C, and D; and
the South Satellite. The total future emergency power need of these spaces is currently
unknown. Therefore, the preliminary design will focus on designing the smoke control system
for all areas except the South Satellite, and evaluate any other code required emergency power
needs to determine the total system requirement. The South Satellite will get its own dedicated
emergency power and smoke control systems when it is renovated. The future C1 building will
also be incorporated into the total emergency power needs. It is important to know the
number of generators necessary in order to find an appropriate location for the new
generators. 
All of this must be completed in a facility that is operational 24 hours a day, every day of the
year. Although currently passenger traffic is reduced, it is anticipated that traffic numbers will
return, and the project will need to be able to limit impacts when that occurs. This is a complex
project and the preliminary design is an important first step to help mitigate some of the
unknown risks to be able to provide a better cost estimate and schedule. 
In addition to the design of smoke control and emergency power, the designer will be required
to provide an estimated overall project cost for the Main Terminal upgrades. 
Staff will return to the Commission to request authorization of the preliminary design work. It is
expected that this work will take approximately a year to complete, after which staff will return
to Commission to report back on the findings and request design funding.
