Bart Bretherton, RG Region 2 Hazmat Coordinator Lessons Learned from Unanticipated Cleanup on a Preservation Project (a tale of whoa)
Defining Factors During Project Development January 2004 Project starts Scoped as Pavement Pres job No hazmat anticipated Expected completion- one const. season Midpoint in project development Project expands with addition of SWIP Funds Dec 2005 Hazmat Phase 1 requested by R/ W and Project Leader May 2006 Project let R/W develops area of take
Consequences of Unanticipated Hazmat to Project Construction Project completion time severely impacted Almost doubled! Significant increase in volume of materials to be managed and disposed 50 tons estimated; 967 tons actually removed Saturated soil increased actual tonnage and management issues Additional subcontractors necessary Licensed tank removal contractors and continual hazmat supervision Unanticipated hazmat issues were 40-50% of total cost overrun $600K over engineer’s estimate
Lesson Learned: Involve Hazmat in Early Scoping and Part 3 Dev Issue: Part 3 did not recognize and/or include possible hazmat sites. Easily retrievable public documents were not reviewed. Notable site characteristics were not evaluated for impact to the project. Resolution: Essential to include the Region Hazmat Coordinator in review and preparation of Part 3.
Lesson Learned: Beware of Project Scope Creep Issue: Addition of SWIP funds in the middle of the project development seriously impacted the Part 3 hazmat evaluation. Required property acquisition and trenching. Should have triggered a full Phase 1 earlier.
Issue: Late hazmat evaluation prevented needed Phase 2 work. Phase 2 would have greatly increased ability to evaluate the financial impacts and constructability of the project. Phase 2 would have produced more accurate info than RP supplied site information. A lack of characterization resulted in incomplete 00290 special provisions. Resolutions: The 2005 implementation of PD-02 helps to limit scope creep. Hazmat review should continue through entire development process up to PS&E. Don’t just “check the box” as completed – read the report! Lesson Learned: Beware of Project Scope Creep cont.
Lesson Learned: Obtain Cost Sharing Agreements with Property Owners ASAP Issue: Too many property owners and multiple agencies involved. No time to negotiate agreements and assign liability or; Litigate responsibility. Resolutions: Leave sufficient time to interact and negotiate with property owners. Develop well-defined cost recovery process.
Lesson Learned: It’s Not Over Until It’s Built Issue: Contractor did not have sufficient special provisions. Resolution: Make sure to have all special provisions for increased project flexibility.
In Closing: There are some things that are fun to dig up. (Petroleum contaminated soil is not one of them!)
