Project Description

The YMCA of Greater Houston retained InControl Technologies to conduct environmental consulting and engineering services on numerous projects at various locations within Greater Houston.  The most significant of these projects was the relocation of the downtown YMCA from its original 1940's location on Louisiana Street to its new location on Pease Street.  These projects included Phase I and Phase 2 Environmental Site Assessments, soil and groundwater remediation, underground storage tank removal, asbestos abatement and building demolition.  InControl Technologies served as the environmental construction manager for projects and the asbestos abatement and building demolition of the former Downtown YMCA.  These two projects were done in conjunction with one another.

InControl Technologies conducted a limited Phase 1 and Phase 2 Environmental Site Assessment at the planned property for the new Tellepsen YMCA—a parking lot area located within the downtown Houston area.  This property once housed a former car dealership, numerous repair facilities and a historical paint and body shop.  Soil and groundwater samples were collected to determine if these facilities had impacted the shallow soil.  After the property was cleared, and prior to the new construction, several hydraulic lifts were identified along with two former underground storage tanks. The tanks were suspected to be a former fuel oil tank and a former used oil tank.  These tanks were removed along with 600 cubic yards of petroleum hydrocarbon impacted soil.

After the completion of the new Tellepsen YMCA, InControl Technologies was hired to conduct the asbestos abatement and demolition of the former downtown YMCA.  This building was a 12 story concrete and brick building constructed in four different phases.  Prior to demolishing the building, InControl Technologies had to remove all the hazardous materials including items such as water treatment chemicals, pool chemicals, fluorescent lights and ballast, oil tanks, sumps and numerous gallons of old paint.  Two backup generators were also removed prior to demolition.  Freon was captured from the HVAC system and recycled prior to the removal of the system. InControl Technologies also arranged for several nonprofit entities to have monitored access the building and salvage items prior to the demolition.

Once the building was cleared, the abatement of the regulated asbestos-containing, building materials began.  The abatement project included the removal of floor tile, mastic, sheetrock, and pipe insulation.  The vapor barrier along the exterior of the building was above the regulated limit; therefore, InControl Technologies worked with the demolition contractor to segregate that material which ultimately reduced the amount of material which required disposal in a regulated landfill. The building was demolished and the rubble was allowed to fill in the basement area.  Once the building foundations were removed, the hole was backfilled with a select fill material. The property was crowned and seeded; it now serves as a green space in downtown Houston.
