The Ottawa International Airport joins the increasing list of new and renovated airports that have decided to use Architecturally Exposed Structural Steel to define their building.
Ottawa's new three-level passenger terminal building is linked to the second level of the existing terminal by way of a passenger bridge. Canadian customs and the US pre-clearance facilities have been expanded to accommodate growth in trans-border air traffic. Fifteen new gates have been added to the airport's existing twelve arrival and departure gates. Updated baggage handling facilities, expanded airside aprons to ease congestion on taxiways, a new de-icing facility for aircraft, climate-controlled access to the passenger terminal from an above-ground parking garage and a realigned airport parkway approach have been constructed during this first phase of expansion.
The Ottawa International Airport Expansion Program was honoured at the 2004 Canadian Consulting Engineering Awards. Hosted by the Association of Consulting Engineers of Canada and Canadian Consulting Engineer magazine. The Ottawa Airport received awards in two categories, both of which included significant and worthy construction projects from Canada and the U.S.
The first, in the Buildings category, recognized GENIVAR, who in partnership with Brisbin Brook Beynon, designed the terminal’s stylized structural components to create an elegant, efficient and pleasing avant-garde roof design.
The second, in the category of Project Management, recognized the MRM Project Management team which was a very successful joint venture between Marshall Macklin Monaghan Limited of Toronto and J.L. Richards & Associates Limited. The team managed the entire program from its inception to completion, delivering within budget and six months early.
The terminal building is 304 m long, 107 m deep at its widest and has three levels, plus the 6-m deep below-grade basement level. The superstructure has an elegant and efficient design, with high-finish, stylized structural components. Check-in and departures is on Level 3, express departures is on Level 2, and arrivals and baggage claim is on Level 1. The facility includes a transborder waiting area, a waiting and concession area with views of the airfield and a special water sculpture that represents the bodies of water that converge in Ottawa. There is also a giant video wall featuring national news. Two climate-controlled pedestrian bridges join the terminal to the adjacent parking structure.
Technical advances that were largely developed during the detailed structural design include:
• development of unique ways to apply common shrinkage and creep control methods to large-scale continuous concreting of deep foundation walls;
• use of friction piles as tension tie-down anchors to resist uplift;
• use of an elegant, architecturally designed diagonal strut-and-bar arrangement in the exposed bracing system;
• development of a continuous, architecturally exposed feature truss with forked "Y" end spans;
• use of a feature truss stabilization system to resist unbalanced loads;
• achievement of a long, joint-free building using a simple, temporary construction joint system;
• production of scaled 3-D shop drawings detailed down to the bolt and notch level using high-tech computer simulations, displays and drafting.
