Representative Consulting Assignments

  • High End Apartment Complex | Sewage System Failure | Plaintiff sought complete replacement of underground waste and sewer piping. Our photo survey of piping found most of piping to be of proper construction including proper slopes. Piping was heavily blocked by solidified fats that accumulated other wastes forming blockages. There were 2 sections of piping that contributed to blockages due to a swale in the piping. The pipes were parallel and below the parking area. It appeared a vehicle had rolled over the piping prior to concrete placement. The plumber's insurance agreed to replace only that section of piping. The primary cause of blockages was improper disposal of FOG fats, oils and grease by tenants.
  • Office/Retail Building | Due Diligence Survey | Performed Due diligence survey of 1,000,000 SF Class A 53 story office/retail building for purchaser prior to sale.
  • Office Building | Fire | 7 story office building rooftop fire evaluated equipment loss in rooftop mechanical room and water damage on lower floors caused by fire fighters.

Primarily related to mold and moisture remediation then repair and replacement of electrical switchgear, HVAC equipment, life safety systems and central plant equipment rehabilitation. A refrigeration unit had failed. A maintenance crew attempted to repair the unit. They failed to follow proper procedure to bleed pressure off the compressor head prior to opening the pressure vessel. After removal of most of the retaining bolts, the cover plate released from the gasket, shearing the remaining retaining bolts. It then partially decapitated the worker and cause a limb loss for the supervisor. Root cause of the incident was determined.
