Project: Ohio Expo Center Gilligan Complex Parking Structure

Owner: Ohio Exposition Commission

Year: 2014

Cost: $1,785,000

Project Manager: Hamid Mukhtar, PhD, PE
Lead Structural: Ali Alghothani, PhD, PE

Scope: The Gilligan Complex was constructed in 1978 and is approximately 310,000 square feet. The building has a concrete framed structure with an 8î thick pre-cast concrete plank and 3î topping parking deck which accommodates approximately 750 cars. The area below the parking level houses space for horse stalls, cattle ties, wash bays, meeting rooms, offices, a restaurant, and restroom and shower facilities. Vertical circulation is achieved through 10 stair towers for pedestrian traffic, and 2 ramps for vehicular traffic.

The scope of work related to the Gilligan Complex project included design and construction necessary to correct ALL water intrusion ìwater proofingî from the existing parking deck to ALL parts of the lower level, structural repairs and replacement of steel connections throughout the facility. Project had an aggressive schedule to meet Quarter Horse Convention opening deadline.

Work was performed in time to meet ownerís schedule. Liquid applied Vehicular traffic deck coating was selected to fit the project budget. Existing concrete and metal connections were sandblasted to achieve desired surfaces to adhere the coating. QA/QC was enforced during construction to make sure all coating was installed as per manufacturerís recommendation so that a 5 year water proofing warranty can be obtained.

Project: ODRC Marion Concrete Floor Repair

Owner: Ohio Department of Rehabilitation and Correction

Year: 2004

Cost: $631,000

Project Manager: Ali Alghothani, PhD, PE

Scope: Forensic investigation of six dorms second floor cracks, disintegrating, vibration, & Repair/Replacement of the flooring to maintain the structural integrity of these structure. Star Consultants, Inc. performed a forensic inspection of the wind loss and a study of the structural integrity of the flooring system of the above referenced group of dorms located in Marion, Ohio. The Ohio Department of Rehabilitation and Correction identified the cause of cracks and commissioned Star to replace Concrete Flooring in six dormitories (with a total area of about 15,360 SQ.FT) at Marion Correctional Institution.

Star investigated the existing Concrete Flooring, took core samples and bar scanning, determined source of problems, and proposed several options as to the replacement of the Concrete Flooring. Existing Concrete Flooring in these dormitories is made up of metal deck (0.6C28), 2î concrete without re-bars, and 1 Ωî finish floor. Major cracks were observed. These cracks did undermine the structural integrity of flooring. In addition, existing separation (damage) of finish floor from concrete flooring and separation between metal deck and concrete flooring produced large unacceptable deflection. Based on a visual inspection, metal deck looks sound and in acceptable condition. Our forensic inspection has indicated that existing metal deck is to remain in place and used as part of the new concrete flooring system. This will help protecting first floor from debris. This process would not require general temporary shoring. Existing finish floor and concrete flooring will be saw cut, removed, and replaced with new high strength concrete, re-bars, and finish flooring. Studs will be utilized and tack welded to make a composite section and to ensure bonding between concrete, metal deck, and joists. This mechanism will ensure controlled and acceptable deflection

Project: Fire Training Academy Structural Design

Owner: City of Columbus

Year: 2007

Cost: $8,600,000

Project Manager: Ali Alghothani, PhD, PE

Scope: Structural Engineering Services for the new training center which consists of four individual training structures including

1) a practical skills building
2) a burn building
3) a training tower
4) a roof simulator

The practical skills building consists of a 2-story, 26,099 square foot structure that features two classrooms and six apparatus bays for indoor training activities and storage of training apparatus. In addition to the apparatus bays, this building has a 2-story wing that includes a mezzanine is utilized for training activities such as ladder evolutions, rappelling, hose advancement, and forcible entry. This building also includes a wet area for sprinkler and standpipe training. Building is equipped with egress steel stair for the 2 story building.

The training tower is a 6-story, 1,672 square foot structure that is used for search and rescue training, high rise drills, and high angle rope rescue training. Each level of the tower has a removable floor grate for multi level confined space simulations. Tower is equipped with egress steel stair for the 6 story building.

The burn building is a 2-story, 1,239 square foot structure. It is equipped with five rooms on each floor and a low clearance attic. There is one natural gas fired burn simulator on each floor and in the attic. The building also contains balconies, various window configurations and roof pitches, an enclosed stair tower, utility props, and multiple anchor points for rope training.

The roof simulator is a single story, 763 square foot structure used to train firefighters on ventilation techniques on roof structures.
Structural Engineering: Entire structural design which includes foundations, elevated concrete slabs, steel girders and columns, masonry shear walls construction, spread, strip, and foundations.

Project: Structural Building Design for Fifth Third Bank

Owner: Arshot Investment Corporation

Year: 1997

Cost: $8,120,000

Project Manager: Ali Alghothani, PhD, PE

Scope: This historical seven-story structure was built in 1927. The owner desired to expand building vertically to sixteen stories and horizontally one extra bay. Structural configuration presented a challenge where the building was un-symmetric. Unable to rig caissons underneath structure and type of steel grade were other challenges to be overcome.

A sixteen stories high building, approximately 150, 000 sq.ft. was constructed. Design of structure included; concrete slab composite deck, structural framing and bracing, rigid frames, spread foundations, and foundations on group of piles. Evaluation of original existing structure was simulated through three-dimensional analysis.
