## [[Risk Action Plan]] ### [[Risk Description|Description]] Due to the age of existing structures on the water reclamation campus, there is a threat that demolition activities may encounter asbestos-containing materials or lead-based paint not identified in the pre-construction survey, which may lead to abatement costs, schedule delays, and worker safety concerns. > [!abstract]- Risk Analysis — Key Assumptions & Current Controls (click to expand) > > **Key Assumptions:** > - The pre-construction hazardous materials survey completed in September 2025 covered all structures scheduled for full demolition, but was limited to accessible surfaces; inaccessible cavities, pipe insulation within wall chases, and below-grade encapsulated materials may not have been fully characterized. > - The primary demolition scope includes a 1962-vintage pump house structure and a 1978 chemical feed building — both pre-date EPA asbestos regulations and are high-probability candidates for asbestos-containing pipe insulation and floor tile. > - The pre-construction survey identified and quantified known asbestos in two locations (boiler room pipe insulation and floor tile in the pump house); these quantities are included in BUILT RIGHT CONSTRUCTION's contract price and are being managed under a BUILT RIGHT CONSTRUCTION subcontract with a licensed abatement contractor. > - Any additional hazardous materials discovered during demolition beyond the surveyed quantities are potentially a differing site condition and may qualify as a change in the work. > > **Current Controls:** BUILT RIGHT CONSTRUCTION's abatement subcontractor is a Mushroom Kingdom licensed hazardous materials contractor with an active air monitoring program during demolition. A stop-work protocol is in place requiring all demolition work to cease and the abatement subcontractor to be notified within 1 hour of any suspected hazardous material discovery. EPIC Water Authority has been notified of the survey limitations and acknowledges the potential for additional finds. > [!abstract]- Sources of Information & References (click to expand) > > **Sources:** > - [[EXHIBIT C - General Conditions]] > - [[Section 01 57 00 Temporary Controls]] > > **Attachments:** > - None ### [[Risk Mitigation Strategy]] Transfer the financial and schedule consequence of unanticipated hazardous materials discovery to the appropriate party through clear contractual documentation. [[Wario]] is to ensure that any discovery of materials beyond the surveyed scope is immediately documented, photographed, and reported to EPIC Water Authority in writing per the differing site conditions notice requirements. The stop-work protocol must be followed without exception — unauthorized disturbance of suspected asbestos-containing materials creates regulatory liability for all parties. BUILT RIGHT CONSTRUCTION's contract includes a provisional allowance mechanism that can be used to fund additional abatement scope if authorized by EPIC Water Authority. ### Possible Additional Actions - Commission supplemental destructive sampling in the wall cavities and below-grade areas of the 1962 pump house prior to the start of structural demolition, to reduce the probability of an in-progress discovery that would trigger a work stoppage. - Confirm with BUILT RIGHT CONSTRUCTION's abatement subcontractor that their scope and unit pricing covers the full range of potentially encountered materials (asbestos pipe wrap, floor tile, drywall compound, lead paint) so that additional discoveries can be priced quickly without procurement delay. - Engage Mushroom Kingdom environmental regulators proactively to confirm notification procedures for unanticipated asbestos discoveries, ensuring the project team understands reporting timelines and required response actions before demolition begins. - Review EPIC Water Authority's insurance coverage for hazardous materials incidents to confirm the project is covered for abatement cost overruns that cannot be transferred to BUILT RIGHT CONSTRUCTION. ### Comments & Recommendations The consequence is rated "high" because an unanticipated asbestos find during active structural demolition triggers mandatory work stoppage, regulatory notification, and emergency abatement mobilization — all of which are time-consuming and costly. The "unlikely" likelihood reflects the thoroughness of the pre-construction survey, but the age of the structures means this risk cannot be eliminated. Supplemental destructive sampling before structural demolition begins is the highest-value additional action available and is strongly recommended. ### Status - [ ] [[2026-01-22]] ^status-2026-01-22 - 📊 **Survey Limitations Identified:** Risk identified during pre-demolition planning review — the September 2025 hazardous materials survey was limited to accessible surfaces and did not characterize inaccessible wall cavities or below-grade encapsulated materials in the 1962 pump house or 1978 chemical feed building. - ⏳ **Supplemental Sampling:** [[Wario]] evaluating cost and feasibility of supplemental destructive sampling in wall cavities prior to structural demolition; decision needed before demolition mobilization currently scheduled for April. > [!abstract]- Status History (click to expand) > > *(No prior entries)*
