CTDCS On-Call Structural Engineering
New Haven, CT
AI provided design services for an on-call engineering services contract for the CT Department of Administrative Services (DAS), Division of Construction Services (DCS). Tasks included preparing schematic design, design development, final design, and contract documents. The following projects represent some of AI's assignments under this on-call contract:
- Gateway Community College (GCC) Replace AHU 2 and 4, New Haven, CT - AI was tasked with designing the replacement of two existing roof mounted air handling units (AHU) at GCC. As part of this work, the existing AHUs and their installation on the roof were inspected. During our investigation, a roofing contractor uncovered deteriorated roof conditions during a routine roof repair. Based on our further investigation of the roof support systems for the AHUs, this project was halted and an emergency roof evaluation was performed.
- Gateway Community College (GCC) Emergency Roof Evaluation, New Haven, CT - Based on findings from the prior AHU replacement project, AI was tasked with investigating the condition of the roof deck and framing at GCC. AI provided an assessment of whether the building was safe to be occupied. Based on the field investigations, AI determined that the building may continue to be occupied through the end of the 2013 school year except during times of a high wind event. Furthermore, AI recommended that the building remain unoccupied after the end of the 2013 school year and through the winter until a complete roof repair/ replacement is performed.
- GCC EEPC Construction Cost, 60 Sargent Drive, New Haven, CT - As a follow up to an emergency roof evaluation, AI was tasked with performing a review of the roof framing for adequacy to carry code mandated loads and provide a cost estimate for repair of the roof and any associated structural repairs and strengthening. The structural evaluation revealed that the existing roof structure did not meet the current building code. By analysis, the existing roof structure had less than half of the capacity it required to support the building code prescribed snow loads. Based on the structural analysis, the roof would require strengthening to meet current building codes. In addition, AI also conducted a cursory review of the building exterior. The building envelope was found to be in satisfactory condition.
