About this file
This Addendum #1 is issued by the Iowa Department of Administrative Services for RFB 927950-01, the WRC Decentralization Phase 5 project at Woodward Resource Center. The addendum modifies the original bidding documents dated April 24, 2026, and must be acknowledged in the IMPACS electronic procurement system to avoid bidder disqualification. The project involves demolition of utilities in existing tunnels, rerouting of water lines, and filling tunnels with grout. Construction is scheduled to begin July 6, 2026, and conclude June 30, 2028. The bid submission deadline is June 9, 2026, at 2:00 p.m. A pre-bid meeting was held on May 21, 2026, with an additional meeting on May 27, 2026; both sign-in sheets are attached as exhibits. Key clarifications include coordination requirements between bid packages for open excavation areas and water capping, and the presence of existing temporary shoring in two 50-foot tunnel sections that will remain throughout the project.
The base bid construction budget for Bid Package 01-1 is $2,000,000. Critical contractual requirements include umbrella liability insurance limits tiered by contract value: $2,000,000 or more for contracts under $1,000,000; $5,000,000 or more for contracts between $1,000,000 and $5,000,000; and $10,000,000 or more for contracts exceeding $5,000,000. The addendum clarifies operational responsibilities, including that BP 01-1 is responsible for all abatement-related temporary power and lighting, dewatering of tunnels until clearance, supplying its own dumpster, and coordinating sewer connections with the facility. Following air clearance testing using PCM samples, BP 03-1 assumes responsibility for pumping water before grout filling. Additional provisions allow use of laborers for steel removal post-abatement, multiple containment zones, temporary generators, and ground-level power in conduit with facility coordination. The facility provides hydrants for contractor use and will handle traffic control; no permits are required unless roads are closed.

TO: PROSPECTIVE BIDDERS:
THIS ADDENDUM FORMS A PART OF THE BIDDING AND CONTRACT DOCUMENTS AND MODIFIES THE BIDDING DOCUMENTS DATED 04-24-2026, WITH AMENDMENTS AND ADDITIONS NOTED BELOW. THIS
ADDENDUM SUPERSEDES AND SUPPLEMENTS ALL PORTIONS OF THE ORIGINAL BIDDING AND
CONTRACT DOCUMENTS WITH WHICH IT CONFLICTS. ACKNOWLEDGE RECEIPT OF THIS ADDENDUM
IN THE IMPACS ELECTRONIC PROCUREMENT SYSTEM. FAILURE TO DO SO MAY DISQUALIFY THE
BIDDER.
CLARIFICATIONS:
• Coordination will be required between BP 01-1, 03-1, and 23-1 for the open excavation areas for water capping.
• There is existing temporary shoring in two 50’ sections of tunnel that will remain throughout the project.
QUESTIONS AND ANSWERS FROM PRE-BID MEETING
Q1. Can BP01-1 use laborers to remove steel after the abatement is done and the area passes clearances?
A1. Yes.
Q2. Are multiple containment zones within each phase allowed?
A2. Yes.
Q3. Is power available from additional buildings?
A3. Please indicate which additional buildings would be helpful and we will clarify in a future addendum.
Q4. Can the BP01-1 provide a temporary generator if needed?
A4. Yes.
Q5. Can the temporary power for BP01-1 be run on the ground?
A5. Yes, but the location will need to be coordinated ahead of time and must be in conduit.
Q6. Where can BP01-1 connect to the sanitary sewer?
A6. Where availability allows. WRC uses lagoons for treatment and needs to follow rules pertaining to the materials allowed to enter the treatment system.
Q7. Are the temporary power and lighting for abatement the responsibility of BP01-1, not
BP26-1?
A7. Yes, all abatement-related temporary power and lighting (except for the lighting provided by the facility) are the responsibility of BP01-1.
Q8. Are there hydrants available?
A8. Yes there are hydrants available throughout the campus for use by the contractor.
Q9. What are the excess or umbrella liability insurance limits?
A9. Per section 10.2.2 of the ConsensusDocs 802 included in the Project Manual:
i. contracts less than $1,000,000 must carry a $2,000,000 or more umbrella;
ii. contracts from $1,000,000 to $5,000,000 must carry a $5,000,000 or more umbrella;
iii. contracts greater than $5,000,000 must carry a $10,000,000 or more umbrella.
Q10. Are there any restrictions for dumpsters on site?
A10. BP01-1 must supply their own dumpster. This dumpster can generally be located close to abatement areas, but the exact locations will need to be coordinated with the facility. CM will provide the dumpsters for all other bid packages.
Q11. Is there on site storage for demolished pipe?
A11. Yes. Short term storage as needed.
Q12. Who will handle the traffic control? Are there any permits required?
A12. WRC will handle traffic control. No permits required unless roads are closed.
Q13. Does there need to be a stronger grout mix for areas that have a road on top?
A13. No, one grout mix for the whole tunnel will be acceptable.
Q14. Can you clarify the responsibility of dewatering the tunnels since multiple bid packages are responsible for this task?
A14. BP 01-1 will be responsible for all dewatering in the tunnels until they are completed and have passed their air clearances. After clearances it is the responsibility of BP 03-1 to pump out any water before filling tunnels with grout.
Q15. What type of air clearance test will be used?
A15. PCM clearance air samples will be conducted and analyzed for each containment location prior to occupancy by other trades.
Q16. What is the construction budget for BP 01-1?
A16. The budget for base bid work is $2,500,000.
