 Is Construction Related Environmental Consulting Right for you?

Construction related environmental consulting and remediation services are normally required where contamination may be encountered during construction at the following types of facilities:

  • Potential petroleum Contaminated Areas
  • Sites with Petroleum Storage Tanks
  • Maintenance facilities where waste was stored or generated
  • Facilities with industrial or manufacturing activities
  • Former oil and gas exploration and production sites
  • Other oil and gas tool manufacturing facilities

All of these facilities fall under Federal, State, County, and Municipal Government projects and need strategic planning as well as close coordination to successfully have the most safe and effective results. Some things that are needed to achieve those results in these facilities will be to undergo a Phase 1 and 2 Environmental Site Assessments, Waste soil and water screening during construction activities in PPCAs, as well as profiling and approval to dispose at licenced and approved disposal facilities. As always, these types of projects are not limited to these services, but may require a few more services down the road to really ensure safest results.

Project Management – Unforeseen Conditions During Construction

During construction of the new buildings on a new development site in Houston, Texas, several unforeseen site condition issues were discovered including buried ground storage fuel tanks, buried concrete under the drilled piers, and remediation of soil. Because the site was previously used as a vehicle wash facility, Phase I and Phase II Environmental Site Assessment (ESA) was performed. Two areas were identified in Phase II ESA for Potential Petroleum Contaminated Areas (PPCAs).

Due to site constraints for the stockpiling of the contaminated Type I soil and non-contaminated Type II soil, several alternate remediation methods were reviewed and proposed. One of the options was to collect composite soil samples for laboratory chemical analysis of the excavated PPCA soil after they had been excavated and screened with the PID, segregated, and stockpiled on-site as per Specification. The second option proposed by CRG Texas and which was ultimately implemented by CRG Texas was to excavate the area within the PPCA with the sample collected on a grid and screened-in place for every loose 20 cubic yards. The second option was thoroughly reviewed by the Project Management Team based on the construction schedule, frequency of the testing, and return of the testing results from the laboratory. This method was proven very effective in expediting the work within PPCA designated soil.

By implementing this alternate method, the City not only saved the budget allocated for PPCA soil but also expedited the construction schedule.
