Feature Story - October 2003
Glenview Naval Air Station Redo
Glen Town Center Cleared for Takeoff

by Jeffrey Steele

One of the biggest logistical headaches at the Glen Town Center project in Glenview, Ill., was the need to keep hundreds of workers functioning efficiently in a constrained area overrun with trucks and construction work.

"It's a very condensed project, with a lot of square footage and a lot of buildings," said Tom Miller, vice president of development for Chicago-based Transwestern Commercial Services, the construction manager on the project. "On any given day I could have 300 trucks coming in and off this site for deliveries."

He added that it was necessary to manage more than 1,200 workers onsite, as well as trucks and deliveries, and still be able to give the general contractors proper access to their individual sites.

The $150 million Glen Town Center project is on a 48-acre site in the center of the 1,200-acre redevelopment of the old Glenview Naval Air Station. San Diego-based OliverMcMillan is serving as the property developer, and the firm is a part owner of property in the development, along with the village of Glenview.

The project will encompass 13 restaurants, 50 stores, 155 townhouses and apartments in more than a dozen structures. This includes a 150,000-sq.-ft. Von Maur department store, an 80,000-sq.-ft. Galyan's sporting goods store, a 10-screen movie multiplex and two large mixed-use retail-apartment buildings.

In total, 2,533 public parking spaces will be located in the Glen, in garages and elsewhere throughout the development, Miller said.

Groundbreaking took place in late summer 2002, with the grand opening of retail and parking garages taking place this month.

Wood Dale, Ill.-based George Sollitt Construction oversaw two major parking structures, Chicago-based Pepper Construction Co. handled the sitework and Von Maur and Galyan's stores and Minneapolis-based Weis Builders managed mixed-use buildings, some retail tenants and limited parking, said Don Owen of the village of Glenview.

While some townhouses are already occupied, the remainder of them and the apartments won't be complete until March or April.

Design Embraces Diverse Styles

Diversity was the goal in the choice of architectural styles and construction materials used in the retail center.

"We pretty much cover the gamut," Miller said. "We have wood construction, steel and wood, precast concrete, cast-in-place concrete, steel frame. The architects were different from building to building, and the end product is equally different. When you see it, you sense that it's like a small urban city built all at the same time."

Two of the most interesting components of the center are the pair of mixed-use buildings incorporating basement-level parking, ground-floor retail and second and third-story luxury apartments, Miller said. These buildings had to be designed and built to allow for future requirements of ground-floor commercial tenants.

That meant running 64 rated shafts from the first floor through the roof of the structures to serve as "means and methods" to install future tenant improvements.

For example, if a restaurant tenant were to need a duct installed sometime in the future, the 2- by 5-ft. rated shafts would allow the ductwork to be added without compromising any of the apartments through which the duct would travel.

"Once we established the ground rules, we were able to fit the apartments around [the shafts] quite easily," said Timothy Kent, project manager with Chicago's Pappageorge Haymes Ltd., the architectural firm that designed the mixed-use buildings.

And the sanitary lines that feed the buildings' grease traps were installed in the ground. They were piped into the base of the buildings, which will allow future restaurant tenants to tie into the line without undertaking expensive excavation at the site, Miller said.

"Preplanning was the key," he added. "You have to think this through all the way before you finish the base building, the shell. The alternative is to double and triple the cost by doing extra work afterward."

Pappageorge Haymes Ltd. faced other obstacles in designing the two buildings, Kent said. One was that the buildings had to be curved, which meant they couldn't be constructed in modular fashion. Most of the units are different from one another, making the production of construction documents and the construction itself difficult, Kent added.

The buildings also use different construction systems, including cast-in-place concrete for basements, precast concrete for first-floor decks, steel with a composite deck for second floors and wood on third floors and roofs.

"During the initial pricing phase, that was deemed to be the less expensive route, but it made for a more complicated design phase," Kent said.

There also was a high water table to deal with. Just east of the Glen is the 20-ft.-deep "detention basin" for the 1,200-acre development. Because of the number of acres involved and Glenview's relative flatness, the storm sewers had to be dug deep to reach all buildings throughout the site. At its low end, the storm sewer is 20 ft. deep and empties directly into the adjacent detention pond.

"When you go that deep, you get to the point where you're at the same elevation as the lake," Miller said. "Even in standard conditions, the water table is quite high on the site, so we had to do quite a bit of dewatering before the storm sewer and buildings could be built."

Incorporating Special Needs

Von Maur and Galyan's had their own program requirements, meaning the retailers not only designed how their interior space would look but how the buildings themselves would look.

"Typically, the shell architect designs based on estimates of what may happen in that space, and the retailer has his own architect for the build-out," Miller said. "But that base building may not meet the needs of the tenant occupying that space, so you end up making modifications in the building to accommodate the tenant."

Miller said he coordinated the needs of the tenant architect, base building architect and the MEP contractors. In addition, he had to deal with contradictions between what the tenant required and the leases called for.

Has Hangar from 1920s

Not all the retail buildings are new. One of the structures, an aircraft hangar, is the oldest on the property, having been built even before the U.S. Navy acquired the airfield in the late 1930s. This historic hangar building is being seen as a kind of centerpiece of the Glen, and it will house a bookstore, cosmetics shop and other stores.

Bernie Woytek, an associate with Chicago-based Gensler, the architectural firm responsible for the renovation of the hangar, said the building is a historic landmark built during the 1920s when the airfield was a privately owned, independent flight school. It remained on the property after the field became the Glenview Naval Air Station.

"Because it was a registered historic building, we needed to go through the state's historic preservation office," Woytek added. "The original hangar consisted of five large bays, one of which has been maintained. The front of the hangar had some masonry structures that were like the front door. They have been maintained and refurbished and incorporated into the retail storefront."

When Glen Town Center is finished, designers believe it will remind visitors and residents of the downtown areas of older Chicago suburbs and will boast a decidedly pedestrian feel.

"The goal of the architecture for these buildings was to recall the main street experience in other North Shore communities, such as Winnetka and Lake Forest, and to evoke that kind of architecture," Kent said. That meant the inclusion of such design features as gable roofs, abundant masonry and a variety of window shapes, sizes and colors. It also meant tucking parking lots behind buildings and avoiding setbacks to give streets a lively pedestrian orientation.
