Sabra, Wang & Associates, Inc. (SWA) was called as the emergency response support service for an MTA Parking garage at BWI Airport. The emergency response was due to a patron complaint of an uneven wearing surface. SWA performed the initial field visit and identified that the problem stemmed from excessive movement of an expansion joint on the seventh level of the parking garage. Due to the excessive movement, the concrete suspended slab slipped off the bearing creating an uneven riding surface. The upper levels of the garage were immediately closed to patrons and a temporary jacking/support system was put into place while SWA designed a permanent repair. SWA prepared several options and presented them to MTA. After several discussions between SWA and MTA it was decided to rebuild the ends of the resting slab with additional reinforcing, install structural steel angles on the resting slab to increase the bearing area, and install post tension rods to restrict the suspended slab from excessive movement. SWA designed the steel supports and jacking system as well as the structural steel angle and sequence of construction used to perform the final repairs. SWA utilized a flexible rubber joint to allow normal expansion/contraction of the joint, but still provide a smooth riding surface for patrons. SWA provided onsite support during construction to ensure the repair was being implemented as intended, answer any contractor questions, and ensure the safety of the public during construction. During the permanent repairs, the parking garage was closed to all patrons.

Bridge Inspections Stream Soundings Inspection Reports Load Rating

Sabra, Wang & Associates, Inc. (SWA) as a subconsultant to the Wilson T. Ballard Company, was responsible for the inspection of 16 bridges in 2011 Cycle and 11 bridges in 2013 Cycle, throughout Montgomery County. These inspections included general inspection, scour inspection, and load ratings. The structures inspected consisted of concrete slabs, structural plate pipe arches, concrete box culverts, steel trusses, and concrete tee beams. Hands-on inspections were performed for vehicular bridges over waterways. Waders and a ladder were utilized to gain access to the structures. Stream soundings were taken for bridges over waterways and compared to the base year data to track changes to the stream bed. Written inspection reports were prepared for each structure which included identification photographs, summary of findings, photographs for notable defects, review of load ratings (if available), repair recommendations, Structural Inventory and Appraisal (SI&A) forms, PONTIS forms, and sounding data. The reports were completed using InspectTech. Performed one load rating for a concrete slab bridge.

SWA is part of the General Engineering Consultant team that is working on designing a 14 mile East-West corridor of the MTA Light Rail that would connect areas of Woodlawn, Edmondson Village, West Baltimore, Downtown Baltimore, Harbor East, Fell's Point, Canton and the Johns Hopkins Bayview Medical Center Campus. Sabra, Wang and Associates, Inc. (SWA) was tasked with drawings collection and performing the inspections of several buildings along the downtown tunnel portion. The downtown tunnel starts along North Fremont Ave at the intersection with Mulberry St and resurfaces on Boston St near Lakewood Ave. The majority of the tunnel is underneath Lombard St and Fleet St. For the MTA Red Line extension project in Baltimore City Maryland, SWA personnel was support to the GEC for building inspection and protection pre-construction. SWA personnel were tasked to obtain structural drawings from various sources including various Baltimore City departments, property owners, property managers, architects/design firms, and various societies for 97 buildings along the proposed alignment. SWA then coordinated with building owners and property managers to perform the

structural condition assessment of the 97 buildings. The purpose of the inspection was to verify the information obtained on the drawings were as-built conditions, confirm the sub-surface depth below grade, and perform a structural condition assessment. If drawings were not available, SWA personnel field measured and drew sketches of sub-surface levels with enough framing and material details for design engineers to calculate foundation loads. Written reports were prepared for all buildings inspected which included framing and foundation type/material, summary of observed defects, general photographs to show a representation of the levels inspected, defect photographs of any significant defects noted, and any pertinent structural drawings. SWA performed the foundation load calculations for all 97 buildings based on the obtained drawings and prepared inspection reports. When drawing or inspection reports were unavailable, SWA using engineering judgment based on experience with similar building to reasonably model foundation loads for each building.

Sabra, Wang & Associates, Inc. (SWA) performed the hands-on inspection of five structures for the Maryland Aviation Administration Division of Facilities Design (MAA) around Baltimore Washington International Thurgood Marshall Airport in accordance with National Bridge Inspection Standards (NBIS). The five structures included an 85’ long single span prestressed concrete beam bridge, a 547’ long multifaceted concrete girder/floor beam parking garage structure, a 90’-5” long two-span continuous prestressed concrete box beam bridge, a 62’-3” long single span prestressed concrete box beam bridge, and a 244’-10” long reinforced concrete box culvert.

These inspections provided unique challenges in coordinating with the MAA, TSA, parking garage personnel, and rental car companies as well as utilizing specialty inspection equipment. SWA coordinated all inspection with MAA and TSA. The prestressed concrete beam bridge was inspected utilizing a ladder. The parking garage structure was over a storm water pond. Due to the odd configuration of the parking garage structure, SWA utilized Harcon’s bridge tracker to perform the inspection. The bridge tracker is a tracked scissor lift truck with a 30’ boom. The tracked

wheel system allowed the bridge tracker to move smoothly on the soft uneven storm water pond bottom. The two prestressed box beam bridges were entrance ramps to two different rental car companies. SWA coordinated with each rental car company and performed the inspections by utilizing a bucket truck and multiple single lane closures. The concrete box culvert was access from a short term parking garage to the baggage claim area. The box culvert was inspected using a ladder. The roadway above the box culvert was the departure drop off area for the airport. The top side inspection was coordinated using multiple passes of a mobile lane closure operation. Written inspection reports were prepared for each structure which included identification photographs, summary of findings, photographs for notable defects, review of load ratings (if available), repair recommendations, Structural Inventory and Appraisal (SI&A) forms, PONTIS forms, and sounding data (if applicable).
