Del Lago Resort Parking Garage

The new Del Lago resort casino, between Syracuse and Rochester, New York, features a hotel, bars, restaurants, and a 2,400-seat entertainment concert hall/theater in addition to the casino. To provide parking amenities for the facility, designers created a four-story, total-precast concrete structure that features dimensional window framing and roofline projections that reflect the casino’s architectural style.

The 299,500-square-foot parking structure had to provide three functions, notes Mike Albers, vice president at Walker Parking Consultants, the architect and engineer on the project. The 758-spaces facility offers valet pick-up and drop-off for casino customers, space for valet-parked cars on the first floor, and self-park spaces for casino customers on the upper three floors.

Precast Offers Economy, Durability
Precast concrete was chosen for the project due to the owner’s desire for an economical but durable structure, Albers explains. The team also evaluated cast-in-place, post-tensioned concrete superstructure. Dailey Precast LLC fabricated all of the precast concrete components including columns, beams, double tees, inverted tee beams, spandrels, and stairs.

Tees were cast with 4-inch-thick flanges and 30-inch-deep stems on 34-inch-deep tees. Cost savings were achieved by using preformed cast-in-place concrete washes at the ends of double tees with embedded double-tee chord reinforcing. A cast-in-place topping was applied directly over the precast concrete inverted tee beams and at the perimeter washes.

The four-bay-wide garage, seven bays long, offers two-way traffic flow with 90-degree angled parking. All floors were designed to be flat, using a stacked express ramp at one end of the structure to isolate pedestrian traffic away from vehicular activity. Precast concrete shear walls laterally brace the structure in both directions. They were placed along the building’s perimeter to maximize the openness of interior floors.

‘Terrific Visibility’ Provided
The stalls are 9 feet wide with a 25-foot-wide drive aisle. Floor-to-floor height was set at 12 feet to improve light distribution and sign visibility. “This design resulted in large, open, flat floors that have terrific visibility and wayfinding for the customers to see the doors leading directly into the resort casino,” Albers explains. At Level 2, visitors can walk directly through a set of doors onto the casino floor, with other levels connecting via elevators or stairs.

The structure’s exterior architecture was embellished on the front side with infill panels set between the spandrel panels to create a punched-opening look. Curved, projecting copings are located over the openings. The façade along the roof level was extended higher than the typical spandrel to add visual interest that was in keeping with the Spanish style architecture of the resort casino.

Mockups Aid Spandrel Selection
“The façade color process was a very big challenge, initially getting a paint chip to match,” Albers notes. Multiple mockup panels were created and viewed at the plant using various concrete mixes and depths of sandblasting to find the proper mix. The precaster used several techniques to create different, darker variations, but the client ultimately decided on a very light color that required close attention.

“It was not forgiving in terms of variations and required a lot of care and attention to sandblasting, shipping, and handling,” Albers says. Additional care was required for the precast copings that sit six inches off the exterior garage face, which needed to be field-connected to the openings. All of the horizontal precast components were treated with a corrosion inhibitor and the elevated deck layers were coated with a 100% silane sealer.

A precast concrete stair tower was erected in the southwest corner, with another punch-through stair included in the northeast corner. A third stair was added along the south elevation from grade level to the second floor.

Delivery Restrictions
The project required 499 precast concrete delivery loads (250 of which were double tees weighing approximately 80,000 pounds per load). Half could travel the New York State Thruway from the plant, but the others, due to their size, required alternative routes as well as permitting and escorts for the seven-hour trip. Time restrictions and local unloading restrictions had to be handled as well.

Despite the challenges, the erection moved smoothly, using a 400-ton Liebherr Crane. All components were erected in less than seven weeks. “There was a consistent 15 to 20 tractor-trailer loads on the job site at any given time,” says Eric Subik, of Daily Precast.

The structure also was designed for future expansion, with space for three potential bays allocated to the east side. Removable precast concrete kneewalls on top of L-beams were created to facilitate that expansion.
