Designed this completely new ground-up five-story 497,000 SQ FT hospital.
The design included gravity steel framing, shear walls at the stairwells/elevator shafts, and a driven pier foundation system.
Provided structural engineering support during the construction phase portion of the project including reviewing shop drawings and responding to challenging RFIs.
This project included a new four-story 114,000 SQ FT hospital wing addition. The first level is used for parking with hospital space on the floors above. The design included an owner option for future vertical expansion.
The design included gravity steel framing, moment frame lateral system, and foundation system.
Provided structural engineering support during the construction phase portion of the project including reviewing shop drawings and responding to challenging RFIs.
The project was to build a completely new spring practice complex for the LA Dodgers and Chicago White Sox.
Performed the structural design for 12 support buildings, which included the clubhouses, at the complex. The construction of the buildings included concrete tilt-walls, steel joist roof framing, steel roof decks, and concrete foundations.
After a tenant complained of carpet tiles coming undone, we were retained to figure out why. Our investigation included visible documentation of observed distress and moisture vapor transmission rate testing on the concrete slab. We determined that the slab had an abnormally high vapor transmission rate that caused reversion of the adhesives, resulting in loss of adhesion between the carpet tile and substrate. The moisture also caused physical damage to the carpet tile because concrete has a very high pH, and the leachate from moisture passing through the slab caused damage to the flooring. It was concluded that the carpet tile was apparently constructed without the required vapor barrier.
Hurricane Ida Damage - TSA investigated three self-storage complexes comprising of over 30 buildings.
The investigation involved assessing complete loss buildings, major impact damage to metal roofs/walls, partially detached overhead doors, blown-out wall framing, and a detailed investigation of concealed smaller damages.
These commercial buildings were damaged by hail events from two different storms. TSA's detailed inspection and experience were used to distinguish damages from the two storms. The roof system consisted of PVC membranes with composition shingle mansards.
The investigation included an above-ceiling inspection to better document/understand the source of the water damage.
This beautiful Ludowici Tile Roof on this massive home is a sight to see. However, Hurricane Ida winds caused detached tiles and partially concealed chatter damages.
Detail and experience matter during an inspection. Knowing susceptible locations is important. TSA uses its decades of experience and structural knowledge to investigate where others don’t.
Knowledge of current building code requirements, manufacturer's insulation recommendations, and structural properties of roofing materials need to be considered when making repair recommendations for a damaged roofing system.
Wind Damage - TSA was hired to investigate the damaged warehouse caused by high wind speeds. The roof was blown off and multiple steel joists were damaged as a result.
An interior investigation was performed to determine the extent of the joist damage and provide repairs for the damaged joists.
During an extreme wind event, overhead dock doors blew in, allowing the building to pressurize causing steel roof decking to blow off the building. Steel roof joist framing experienced inelastic distress. Concrete tilt-wall panel damage occurred as building components were being pulled from the structure.
Our staff was quick to respond and provide engineering support so emergency shoring could be installed to brace the unstable structure. Once the building was made safe, our engineers performed a detailed structural condition survey to identify the structurally damaged members and establish the limits of the repair. TSA engineers designed the structural repairs and provided construction phase services while the repairs actually took place.
After Hurricane Ida, a machine shop was dealing with water intrusion issues at the metal roof membrane, putting their expensive machinery at risk.
TSA’s investigation included infrared technology and leak mapping of the water intrusion locations at the interior. This data helped identify distress of the building envelope during the exterior and roof inspection.
A roof collapse can be a serious/expensive structural failure. The cause of the failure is often a very important part of the recovery process.
TSA's thorough on-site investigation showed evidence that the tenant made a very poor choice to cut the bottom chord of a roof joist to install his lift.
TSA work included the structural condition survey, field measuring/documenting the existing structure (no existing drawings were available), designing repairs, and providing construction phase engineering services.
This standing seam metal roof had only been on a few weeks when the eave end became detached and got bent up during a thunderstorm. The roof had recently been replaced due to it being damaged during Hurricane Ida. The opened roof caused massive amounts of water intrusion into the building.
While the thunderstorm was intense the roof should have been able to withstand the storm. TSA's thorough investigation found a major construction defect. The contractor did not install hold-down clips at many of the purlins at and near the eaves.
Fire Damage - TSA was hired to investigate the extent of the damage to the business caused by the fire.
No structural plans were available so the existing structure members had to be field measured for identification purposes.
TSA determined the extent of the damaged zone of the steel joists, concrete wall, and steel deck.
Following the investigation, TSA provided repair designs and performed engineering construction phase services to fix the building.
This roof collapse happened in a massive warehouse. TSA engineers field documented distress and established the parameters of the repair zone.
This unique structure was partially built with 3D space trusses.
Existing structural drawings were not available. Existing structural conditions had to be field measured and identified.
Following the investigation, TSA provided repair designs and performed engineering construction phase services to fix the building.
Industrial warehouse caused by equipment fire. Fire-damaged steel joists roof framing, steel deck, and concrete tilt wall panels.
TSA investigation determined the extent of the repair parameters.
A repair using steel beams instead of steel joists was also provided for the owner to help minimize downtime.
