- Which roles will influence award and execution (select all that apply)?
- Which procurement constraints must a respondent meet to be considered (select all that apply)?
- How do you typically weight evaluation criteria between technical solution, price, safety record, and past performance?
- What is the typical timeline from solicitation to award for similar emergency/rehab contracts in your office?
- Are there internal procurement approval gates or external funding conditions that could delay award even after technical selection?
What Would Count as a Win?
- If regulators still refused acceptance after reservoir filling, what would that outcome mean for your program’s objectives?
- Which measurable success signals are mandatory for project acceptance (select all that apply)?
- What is the acceptable mobilization window once notice to proceed or emergency mobilization is issued?
- Do you require explicit performance guarantees (e.g., 72-hour cofferdam deployment) and what remedies are acceptable if unmet?
- List the acceptance testing protocols, regulatory hold points, or sign-off steps that cannot be altered during execution.
What's Most Likely To Blindside Us?
- Which single 'unknown' (geology, permitting delays, flood event, contractor performance, supply chain) would derail the schedule or acceptance if it occurs?
- Have previous projects under your oversight required major redesign after construction started? If yes, briefly describe the cause and impact.
- How narrow are your in-water or environmental work windows (select one)?
- What contingency budget or schedule float is typically available for dealing with unforeseen site conditions?
- If the contractor discovers a critical condition requiring immediate redesign, who has authority to approve the change and on what timeline?
Can You Really Mobilize in Time?
- If a contractor guaranteed a 72-hour cofferdam deployment but you required evidence before award, what specific proof would satisfy you?
- Which mobilization assurances do you require prior to award (select all that apply)?
- Do you require pre-cleared staging/laydown areas or is contractor responsible for finding staging within X miles?
- Describe any site access or logistic constraints we must plan for (bridges, narrow roads, weight limits, seasonal closures).
- Do you need evidence of subcontractor qualifications and will those subcontractors be pre-approved prior to award?
Trust, Safety, and Proof — What Seals the Deal?
- Would exemplary dam-construction safety and incident records justify a premium price to you—and why would that matter to your decision process?
- Which of these proof points matter most during technical evaluation (select up to 4)?
- Which safety KPIs or records do you require to approve a contractor (select all that apply)?
- Do you require third-party QA/inspection (e.g., independent instrumentation calibration, NDT, or third-party commissioning) during acceptance?
- How many references and from which types of owners (USACE, Reclamation, state) are expected to validate comparable experience?
Communications When Seconds Count
- If a sudden flood warning occurs while cofferdam/dewatering is active, what immediate actions and communications do you expect from the contractor in the first four hours?
- Who must be notified immediately in an emergency (select all that apply)?
- Which communication channels are mandatory for urgent alerts?
- Do you require an escalation matrix with response SLAs (e.g., acknowledge within 15 minutes, onsite within 2 hours)?
- Are there required public notification or press protocols we must follow in the event of an incident?
Agreement on Next Steps — What Do We Commit To Now?
- If we leave this discovery without clear next steps, what specific risk are you taking on by default?
- What are the top three concrete outcomes you want from our next engagement (site visit, tabletop, draft plan, procurement input)? List in priority order.
- Which documents should we exchange before the next meeting (select all that apply)?
- What is the ideal date range for a joint site visit or tabletop mobilization exercise?
- Please confirm the primary single point(s) of contact for scheduling, technical clarifications, and contracting (name, role, phone/email).
