The parking garage, constructed with concrete slabs on metal deck supported by steel beams and columns, includes two below-grade levels under a twenty-story office building built around 1985. SGH performed a condition assessment and...
The swimming pool at Medford High School was constructed in 1970 and exhibited spalling, staining, leakage, and exposed corroded reinforcing bars on the underside of the pool deck; corrosion of the pool piping and pump components; and staining of...
The natatorium was constructed in the early 1970s as an addition to the high school. The pool and deck are constructed of reinforced concrete and precast plank forms the ceiling. SGH evaluated the condition of the natatorium as part of a school...
The pool complex at the War Memorial Recreation Center was designed and built around 1955. The complex comprises three separate pools (a 31 ft diameter circular beginner’s pool, the 43 ft by 76 ft main pool, and a 33 ft by 41 ft diving well...
Constructed in the early 1980s by the Arizona Public Service Company, the water reclamation supply system at Palo Verde Nuclear Generating Plant consists of thirty-six miles of prestressed concrete cylinder pipe (PCCP), with diameters ranging...
Constructed in the late 1800s, the Norwottuck Trail Pedestrian Bridge carries the recreational bicycle and walking path over Snell Street. The steel through-girder structure was corroded and the east girder had a large hole. ...
Contact between dissimilar metals can lead to accelerated deterioration due to galvanic corrosion. Standard sample Galvanic Series charts (e.g., ASTM G82) provide general guidelines for compatibility. However, most of these charts are...
The Boston Center for Rehabilitation and Subacute Care was built in two phases, with the north wing dating from 1953 and the south wing dating from 1980. Deteriorated and aged building systems, active leakage, and visible masonry and...
Designed by Strickland and Blodgett in 1927, the Ritz-Carlton Hotel consists of a steel-framed structure clad with brick masonry and accented with decorative cast stone and limestone features. A contributing structure to Boston's Back Bay...
Located in the city’s financial district, 530 Bush Street was originally a power plant. The owner planned to convert the eighty-year-old building to office space and wanted to address cracks and spalling in the terra-cotta cornice...
Engineers and architects often encounter conditions where dissimilar metals are in contact. When these situations arise, it is appropriate to consider the corrosion susceptibility of the materials. Although the term corrosion can be broadly...
Current Wisconsin Department of Transportation policy severely limits the use of aluminum drainage structures (pipe and box culverts) based on the observation of pitting corrosion from deicing salts that led to the failure of an aluminum culvert...
The new signature, steel arch bridge for I-74 over the Mississippi River is connected to the abutments by high-strength, post-tensioned anchorage bars. To achieve a design 100-yr service life for the anchorage bars in an exposed condition, a...
This paper presents findings from a research project on the development of a numerical framework to predict the collapse load of a wharf supported by corroded piles under gravitational loads. Data from a detailed marine investigation performed in...
