Mr. Stewart has over 35 years of consulting engineering experience and is a Registered Professional Engineer in nine states. He earned his Bachelor of Science and his Master of Science degrees in Civil/Structural Engineering at the University of Minnesota and the University of Colorado. He also has an M.B.A. in International Finance from Georgia State University.
Mr. Stewart’s extensive professional structural engineering experience includes design, analysis and construction administration of projects including nuclear power plants, airport facilities, mass transit stations, parking deck structures, pulp and paper mills, highway bridges, light industrial facilities, light commercial buildings, residential structures, retaining walls, and drainage structures. He has acted as the Engineer of Record for a diverse number of structural engineering projects ranging from green field design to investigation, evaluation, renovation and repair of damaged existing structural systems. He has also testified in court as an expert experienced in investigating and analyzing failures in civil and structural engineering disciplines related to residential, commercial, municipal, and industrial buildings. This also includes investigating and repair of foundation failures, structural deficiencies, drainage problems, roof damage, storm damage, verifying construction compliance with applicable building codes, premise liability claims, slip and falls, and contract specifications.
- Repair of an 8-story masonry wall and precast concrete coreslab apartment building that was damaged due to severe settlement problems. Project involved cutting two new expansion joints through all eight floors and reinforcing the masonry bearing walls with epoxy bonded steel straps to take the additional stresses from cutting of the expansion joints. Also provided temporary shoring design such that the majority of apartment building was kept operational during the 2 year construction period. Estimated construction cost was $3.0M.
- Aerial mass transit station and parking deck in Atlanta, Georgia. $25M elevated aerial structures included pre-cast concrete members and post-tensioned concrete members. The three level parking deck was a combination of pre-cast and cast-in-place concrete construction.
- Underground mass transit station and associated subway tunnel in Sandy Springs, Georgia. $30M project that included cut and cover methods used to construct the reinforced concrete structures with rock-bolts added to resist overturning and uplift loads in the basemat.
- Three story expansion of Concourse A at Hartsfield International Airport in Altanta, Georgia. $30M three story steel structure was located directly on top of the existing underground tunnel. The underground tunnel had to be reinforced with post-tensioned beams to support the additional loads of the new structure.
- Underground vehicle access tunnel at Hartsfield International Airport in Atlanta, Gerogia. The top slab of the 200-foot long, $5M tunnel was subjected to a million pound aircraft load from a 747 airplane traversing an active taxiway.
- Bearing pad retrofit project for multiple aerial bridge structures for mass transit authority in Atlanta, Georgia. Active bridge structures were lifted and the elastomeric bearing pads were changed out while keeping trains in operation.
- Repair of two-story precast concrete parking deck in Doraville, Georgia. Design and construction defects of the parking deck required extensive repairs to spandrel beams and replacement of all bearing pads under double-tee floor slabs.
- Design of a 22,500 square foot grocery store in Oakland, California. The masonry bearing wall and wood framed roof had to be designed for high earthquake forces.
- Design of $2M waste water treatment plant in South Blue River, Colorado. The pre-cast concrete roof members and load bearing masonry walls had to be designed for a 10-foot deep snow load.
- Design of a 25,000 square foot building for a chrome plating facility in Fort Collins, Colorado. The open web steel bar joists and metal decking were subject to high corrosive elements.
- Repairs to a 6-story, steel black liquor boiler plant in Natchez, Mississippi. Severe corrosion had degraded numbers steel columns and beams that required temporary shoring of the members and replacement or strengthening of the members.
- Design of a 500-foot long elevated conveyor system for a pulp mill in Ketchican, Alaska. Long-span steel trusses and towers had to be designed for heavy earthquake loadings and extreme temperature changes.
- Rebuild of a 10,000 square foot pre-engineered metal industrial building that was damaged by fire in Houston, Texas. Interior of building included a 400 square foot office area and a 2,000 square foot hazardous materials storage area with 3-hour fire rated walls and doors. Existing undamaged foundations were re-used in the final rebuild. Estimated construction cost was $1.0M.
- Rebuild of a 3,000 square foot, high-end, two-story residence damaged due to flooding in Lyons, Colorado. Rebuilt residence was designed for new FEMA flood resistant regulations and ASCE flood loads. Residence was located within the 100-year flood zone and the relatively high river flow velocity of 9.0 feet per second generated large debris impact forces on the foundations.
- Repairs to a 7,500 square foot, two-story, wood-framed, 12-unit apartment building damaged by a fire in DeKalb County, Georgia. Fire-damaged repairs included half of the roof structure and half of the second floor units. In addition, two of the units were reconfigured to be handicap accessible.
- Design of long-span steel pipe bridges for a paper mill in Longview, Oregon. The 100- foot long by 12-foot wide by 10-foot high steel-tubed trusses supported numerous large and small pipes over active roadways.
