All questions received and the corresponding answers Updated drawing sheets Unit Pricing Form Mandatory pre-bid sign-in sheet

1. Q: There are 15 joints listed in the specifications but 18 joints are shown on the drawings. Which one is correct?

A: Work item 14 should be 18 joints. Sheet S0.4 has been updated and is included in this Addendum.

2. Q: Is there a cost for parking on campus?

A: Yes, everyone parking on campus must pay the daily rate (as of 9/25/26 rates are as follows: Bronze Lots - $5.50, Silver Lots - $7.00, Gold Lots - $8.50).

Additional information is available at the Parking and Transportation - Auraria Campus website: aurariacampus.edu/services-departments/parking/ or by phone at 303-556-2003. Bidders may find parking passes to be more cost effective.

3. Q: Are entire floors, or multiple floors, available to be worked on at a time?

A: Only ½ of a floor at a time may be worked on as the parking garage has to maintain close to full functionality.

4. Q: Is traffic control required?

A: Work areas must be clearly marked with signage and barriers.

5. Q: For phasing purposes, should work be done top to bottom or bottom to top?

A: Up to the contractor, but top to bottom is preferred.

6. Q: Does Buy Clean Colorado apply for the project?

A: Only the metal and rebar on the job will need to comply with Buy Clean Colorado.

7. Q: What are the available working hours?

A: Work hours are 7:00am to 6:00pm.

8. Q: To what extent do utilities need to be re-routed? What procedure should be followed where this occurs?

A: We do not expect that the project will require utilities to be rerouted. If utilities are in the way of construction, contractor shall notify the Auraria Higher Education Center (AHEC) Project Manager (PM) immediately.

9. Q: To what items and scopes does wet curing concrete (7H on S0.2) apply?

A: Wet curing concrete applies to all repair mortars unless the manufacturer provides an alternative curing procedure.

10. Q: Is it acceptable to splice stirrups at stem enlargement? Condition shown will be difficult to impossible without damaging reinforcing steel. (Item 7 19-S3.0) A: #3s can be field bent to achieve installation as shown. Alternatively, it is acceptable to install two (2) C-bars, lap top and bottom 9” minimum.

11. Q: Alternate work item #28 says to re-stripe areas to receive traffic coatings.

The estimated area of traffic coating is listed as 25,100sf and restriping as 150,900sf for restriping on the work list. Please clarify to what extent the re-striping intent is. (Only at traffic coating vs. entire floor vs. entire garage).

Please also provide a spec for the striping material.

A: Re-stripe areas to receive traffic coating. The estimated area of traffic coating is estimated to be 25,100sf. Work Item 28 has been revised. Oil-based traffic paint is preferred; contractor shall confirm compatibility with the polyurethane traffic coating.

12. Q: Please provide locations for work item 13, and which condition shown on 6- S3.1 will occur at each.

A: Work Item 13 (Detail 6/S3.1) is listed as a typical plan work item around the perimeter on sheets S1.6 and S1.7. Contractor shall include this repair at 125 locations per Work List on sheet S0.4.

13. Q: Work item 15 is shown in both plan views and RCPs, and in some cases in the same location (on top and bottom of deck/tee). Please confirm that this work item is meant to appear in plan views and what overhead/vertical surfaces it is referring to at these locations (example GL7/8-J on S1.2).

A: Work Item 15 applies to vertical and overhead surfaces of double-tees, beams, columns, and walls. Where work is called out on plan it typically occurs at wall and column faces which extend up from the level below.

14. Q: For bidding purposes, it is difficult to determine where case 2 on 20-S3.0 occurs, and to what extent it does. Where work items 15 & 17 occur at the same location on RCP/Plan, is it acceptable to assume that all of these locations (in immediate vicinity) are to be full depth repairs, and become work item 18?

A: Contractor shall include this repair for 150sf per Work List on sheet S0.4.

Differences between bid quantities and field verified quantities will be reviewed in detail by the contractor and AHEC PM. Lower or higher quantities of field verified repairs will be handled as a change order. A Unit Pricing Form is being added to the IFB via this addendum. It is a separate attachment and must be submitted with the bid documents at bid closing. This form will be used to calculate any variance in quantities.

15. Q: Is there any concern with supporting the topping slab after removal of the damaged DT section per 19-S3.1?

A: Similar to Note 1 detail 18/S3.1 and Note 2 detail 20/S3.1, if the work extends beyond adjacent tee stems or if areas are larger than 10 SF work must be staged or temporary shoring must be installed.

16. Q: The repair quantities and limits shown in the Contract Documents appear to be based on existing observations. If demolition, sounding, or other field investigation exposes deterioration extending beyond the indicated repair limits, how will additional concrete removal, reinforcing repair/replacement, patching, and associated work be measured and compensated? Should bidders provide or carry any unit pricing for additional quantities?

A: Bid shall include quantities shown in the drawings, work list, and details.

Differences between bid quantities and field verified quantities will be reviewed in detail by the contractor and AHEC PM. Lower or higher quantities of field verified repairs will be handled as a change order. A Unit Pricing Form is being added to the IFB via this addendum. It is a separate attachment and must be submitted with the bid documents at bid closing. This form will be used to calculate any variance in quantities.

17. Q: The Contract Documents require repairs within each half-floor work zone to be completed and inspected prior to reopening that area and proceeding to the next zone. Please identify who will perform the required inspection and the anticipated inspection/approval turnaround bidders should assume for scheduling and pricing purposes.

A: Martin/Martin will perform progress site visits and observation. Inspections will be completed by AEC-West (3rd Party contracted with Auraria).

18. Q: Please confirm whether all Add Alternate No. 1 Level 4 work must be performed entirely within the specified Level 4 closure windows of December 11, 2026–January 3, 2027 and March 12–28, 2027, or whether portions of this work may be performed outside those windows while maintaining the required partial garage operations.

A: Add Alternate No. 1 work may be completed at any time during the construction timeline (provided that contractor maintains only closure of ½ floor at a time, and complying with any temperature/moisture recommendations for the traffic coating).

19. Q: Given the anticipated winter construction period, please clarify whether AHEC has any project-specific requirements for temporary enclosures, heating, minimum ambient/substrate temperatures, or cold-weather protection beyond the applicable manufacturer requirements and Contract Documents. Should bidders assume all temporary heating, enclosure, and weather protection necessary to maintain required curing and application temperatures is Contractor-provided?

A: Temporary heating, enclosures, cold-weather protection are not defined in this contract. Contractor is responsible for meeting the required curing and applications temperatures recommended by the manufacturers.

20. Q: Please confirm that the Contractor is responsible for retaining and paying the Colorado-licensed specialty engineer required to design the temporary shoring/bracing systems, including sealed calculations, shop drawings, required inspections, and certification of the installed shoring.

A: Contractor is responsible for retaining and paying the Colorado-licensed specialty engineer required to design the temporary shoring/bracing systems, including sealed calculations, shop drawings, required inspections, and certification of the installed shoring.

21. Q: The drawings indicate that electrical conduit and other utilities may conflict with structural repairs and require temporary or permanent relocation. Are bidders expected to include the cost of anticipated relocations in the Base Bid?

Additionally, how should unforeseen utility relocations resulting from concealed conditions, including utilities encountered within concrete scheduled for removal, be addressed after award?

A: AHEC does not expect that the project will require utilities to be rerouted.

If utilities are in the way of construction, contractor shall notify the AHEC PM immediately.

22. Q: Please confirm that the work-item quantities identified on Sheet S0.4 are the quantities bidders are to use as the basis of bid and clarify how differences between those quantities and actual field-verified quantities will be addressed after award.

A: Differences between bid quantities and field verified quantities will be reviewed in detail by the contractor and AHEC PM. Lower or higher quantities of field verified repairs will be handled as a change order. A Unit Pricing Form is being added to the IFB via this addendum. It is a separate attachment and must be submitted with the bid documents at bid closing. This form will be used to calculate any variance in quantities.

23. Q: Please identify which testing, special inspection, adhesion testing, concrete testing, welding inspection, and other QA/QC services are Owner-provided versus Contractor-provided, and identify any associated testing or inspection costs bidders are expected to include in the Base Bid.

A: Testing will be the responsibility of the contractor. Special inspections, adhesion testing, concrete testing, and welding inspections will be handled through a 3rd party inspection agency through a separate AHEC contract.

24. Q: Please confirm the staging area available to the Contractor and identify any parking, staging, access, or space-use fees that bidders should include in their bids.

A: Staging and access will be reviewed with AHEC PM at the pre-construction kick-off meeting. No fees will be associated with these items. Parking fees will be required (AHEC will work with parking team to provide parking passes for 2/3 vehicles associated with the project. Other vehicles parking on campus must pay the daily rate (as of 9/25/26 rates are as follows: Bronze Lots - $5.50, Silver Lots - $7.00, Gold Lots - $8.50). Additional information is available at the Parking and Transportation - Auraria Campus website:

aurariacampus.edu/services-departments/parking/ or by phone at 303-556- 2003. Bidders may find parking passes to be more cost effective.

25. Q: Does AHEC have an anticipated Notice to Proceed date or required overall completion date that bidders should use in establishing the Time of Completion durations?

A: Notice to Proceed is projected as November 2, 2026. Completion date is May 14, 2027.

26. Q: Please confirm that bidders are not required to submit a detailed construction schedule or phasing plan with the bid, and that the bid-stage schedule requirement is limited to the calendar-day durations requested on the Bid Form, with the detailed construction schedule and phasing plan to be provided by the successful Contractor after award.

A: Confirmed, bidders are not required to submit a construction schedule.

Within three (3) business days of Notice to Proceed, contractor shall provide detailed construction schedule and phasing plan for AHEC and Engineer review.

27. Q: Please confirm whether SBP-2.1 Apprenticeship Utilization Certification is required with the bid or after award, and whether trades listed on SBP-2.1 that are not included in the Contractor's scope may be identified as “N/A.”

A: Apprenticeship Utilization certificate is required after award. Trades not included in the contractor’s scope can be identified as N/A.

28. Q: For restriping areas receiving traffic coating (work item 28). Can you explain how the quantity of 150.900 square feet was calculated when the area identified to receive traffic coating is only 25,100 square feet?

http://www.aurariacampus.edu/services-departments/parking/

A: Re-stripe areas to receive traffic coating. The estimated area of traffic coating is estimated to be 25,100sf. Work Item 28 has been revised. Oil-based traffic paint is preferred; contractor shall confirm compatibility with the polyurethane traffic coating.

29. Work item 14: there is a discrepancy between the drawings and the work list.

The drawings indicate 18 joints, whereas the work list includes only 15 joints.

A: Work item 14 should be 18 joints. Sheet S0.4 has been updated and included in this Addendum.

30. Work item 15: Is there an estimated square footage for repair associated with detail 19/S3.1(2T flange)? This detail requires rebar dowels and screw anchors (including anodes at lev 1 RCP and lev 2 RCP), which di�er from the requirements for the other overhead repairs. If a quantity for 2T flange repair is not available, please advise whether a percentage of the 1,200 square feet in the work list may be used for estimating purposes.

A: Work Item 15 generally occurs at double-tees on the RCPs. Work Item 15 shown on plans occur at other concrete elements. For costs, assume 95% of the work occurs at double-tees.

31. Is a cementitious product acceptable for the crickets and joint shoulder shown in details 4, 5, and 12 on sheet S3.2 in lieu of epoxy?

A: Yes, in accordance with Work Item 17, minimum 1-1/2” thickness unless the manufacturer’s minimum thickness limitations are more stringent.

32. Is it acceptable to use an allowance for temporary electrical relocation?

A: AHEC does not expect that the project will require utilities to be rerouted.

If utilities are in the way of construction, contractor shall notify the AHEC PM immediately.

33. Could you please update the Phasing Notes on sheet S0.1 of the bid set drawings.

A: Phasing Notes on Sheet S0.1 have been updated and included in this Addendum.
