	CONCRETE/STUCCO/ADHESIVES Rust stains on stucco exterior. GZA proved galvanized lath (as claimed) was not the cause of staining, and that staining was caused by metal particles normal to portland cement, and as such could be reasonably anticipated. GZA developed and recommended chemical removal of rust. The contractor and condo association are working out a mutually acceptable relief.
	ELASTOMERIC SEALANT GZA called in six months after sealant installation to determine why the elastomeric sealant in a large exterior reflecting pool was cured in only half the installation while in the other half it had not cured and depolymerized.GZA investigated the history of the installation. The cured half pool was placed in July; the uncured half was placed during a cold spell in November. All material was from same manufacturer, same batch. GZA determined the pool had been acid etched as a paint preparation within two days after sealant had been installed. The acid etching before the sealant cured prevented and reversed any initial cure was installed without consulting the sealant contractor or manufacturer. The painting contractor paid for all damages and repairs.
	ROOFING/WATERPROOFING, CONCRETE, ASPHALTIC PAVING, MASONRY The condo association alleged sponsor's work done as part of the conversion agreement was improper. GZA inspected and evaluated the work analyzed opposing expert reports and stated approximately eighty percent of the work was proper. A mutually acceptable settlement was achieved.
	OSHA & SAFETY Driver slipped on fixed ladder on truck GZA recommended to litigator that driver's shoes at time of accident be examined. It was found he wasn't wearing the safety shoes supplied by his company. GZA proved truck was in compliance with OSHA and other safety requirements. A settlement was accepted.
	COATINGS AND SEALANT Paint peeling from galvanized metal panels. GZA tested the paint and panels and found the painting contractor painted over old paint that appeared to be sound, however the adhesion was so poor that new paint coating, while compatible, pulled the old paint off during its drying and shrinking. Building sandblasted and repainted.
	TILE AND MARBLE Leaks in bath and shower; Marble has extensive lippage; mismatched in color and grout is irregular. GZA proved that surface to which tile and marble had been applied was not prepared for wet service, was not shaded before installation and the setting bed and grout were improper. Judgment granted
	WATERPROOFING Faulty waterproofing in exterior reflecting pool caused leaks in cafeteria below.GZA inspected area, ran tests, and found the contractor did not check the structure for leaks prior to installing a metal sheet waterproofing. It was found the pipes in the slab that supplied water were faulty. It was determined the waterproofing contractor had agreed to undertake the responsibility to provide leak free pools. GZA recommended and supervised the installation of total waterproof installation.
	TILE GZA reviewed all aspects of the installation including maintenance and found a floor washer/scrubber used was imposing point loads on the tile floor beyond its service limits. GZA recommended discontinuing use of this equipment Quarry tile floor now performing as required, litigation was avoided and the tile contractor was paid for the repairs.
	OSHA AND COATINGS Fumes from a solvent based sealer installed in the outdoor parking lot entered building through windows ventilation system, causing illness and nausea to occupants.GZA proved contractor negligence in that no precautions taken to prevent fumes from entering building and sealer installed when building was occupied.
