. I I MIA. Study included field observation of numerous similar facilities at other cities. Evaluation was based upon selection of the building systems based upon longevity, cost effectiveness, ease in maintenance, local availability of material, warranties and life span to cost ratio. I P&A performed services as a prime consultant for the design and construction phase of these two cargo buildings. Included in the scope of work was coordination with DCAD, HNTB and sub-consultants, structural design, engineering services duri+ ng bidding and construction phase. The construction phase program of this project was unique. In order for the small contractor to be able to bid, this large project was split into small pieces. A total of 69 bid packages were prepared and publicly advertised. Sub-contractors to the General Contractor were selected through the public bidding process. I I In addition to the building, a chiller plant was also constructed to provide air conditioning for three cargo buildings. Two ramps and three bridges were constructed to provide vehicular access.

Investigation of in-place construction was performed to determine the cause of cracks in the post tensioned beams. Specific tasks included the investigation of the following structural components of the parking garage. I I 1- Post tensioned beams and girders with cracks, displaced and ungrouted tendon ducts. Investigation required crack survey and monitoring, impulse radar survey, x-rays, structural analysis and repair recommendations. Also included is review of the original design, structural analysis and review of the proposed repairs. 2- Evaluation of the cracks in column and post tensioned beam core joints, field survey of the cracks, petrographic examination of the concrete, structural analysis and repair recommendations. 3- Review of the cracks in the gap structure beams, structural analysis, recommendation of repairs, design of repairs and field monitoring. 4- Investigation, analysis and repair recommendations for ripples in the parking deck slabs, vibrations in the parking deck, cracks in the elevator lobby slabs, cracks in the retaining wall, cracks in the railwalls and evaluation of the columns with reduced concrete compressive strength. 5- Cost estimate and life cycle cost evaluation for various components of the existing structure, repairs and comparison of various alternates. I I MIAMI DADE TRANSIT I Soutlt Miami Parking Garage Expansion and Site Improvements: The design of all on-site and off-site improvements including a 590 parking spaces with the option of adding a five story parking garage or a three story office building, a new interconnect fire water main servicing the local public areas adjacent to the South Miami Metro Rail Station. The project included on-site drainage system which can handle runoff from a 10 story building on a restricted site without temporarily flooding or affecting public transportation facilities. I The site was complex as numerous utilities were located adjacent to the site, which were not fully documented. The contract documents called for careful exploration during excavation so as not to disrupt vital utilities to surrounding business operations. Traffic maintenance and control were critical as the work involved impact to Sunset Drive, a major arterial. I I I Provisions had to be made to include drainage capability for an existing adjacent site which had previously been utilizing the project site for its storm water runoff. Since the whole site is subject to heavy pedestrian volumes, drainage was very critical as any minor ponding would result in a great inconvenience to users of the Metro Rail Station facility.
