Attachments

• Attachment A: Bid Form (Section 10 of this document)

• Attachment B: Microbial Remediation Protocol, Mold Test Company, May 7, 2026

• Attachment C: Environmental and Residential Microbial Inspection Report with EMSL Analytical laboratory results, final May 7, 2026

2. Background Town Hall is a two-story, wood-frame commercial building constructed before 1978, with an attic, one HVAC unit, and a second-floor apartment space. It sits on a crawlspace foundation with stone masonry walls, wood posts, and an earthen floor. The crawlspace has no vapor barrier, no ventilation, and no drainage, and groundwater from a creek beneath the building periodically rises into it. The building is currently vacant.

Mold Test Company inspected and sampled the building on April 30, 2026. Samples were analyzed by EMSL Analytical, Inc. (AIHA LAP, LLC-EMLAP accredited). Key findings:

• Visible growth at the employee kitchen sink base cabinet. Total visible contaminated area is under 10 contiguous square feet.

• The kitchen sink swab showed Aspergillus and Alternaria at medium levels with fruiting structures or hyphae, Zygomycetes at a medium level, and Chaetomium at a low level.

• A mold odor was noted in most interior spaces, the attic, and the crawlspace.

• Stachybotrys/Memnoniella was detected in air samples from the employee kitchen, storage room, and Mayor's office (20 to 40 spores per cubic meter).

• Identified moisture sources: groundwater intrusion into the crawlspace, and possible foundation water or a past plumbing leak at the kitchen cabinet.

Sample location Total fungi (spores/m³) Relative humidity (%)

Crawlspace 1 4,630 49

Employee kitchen 4,420 37

Storage room 3,180 36

Crawlspace 2 890 50

Mayor's office 880 33

Board room 697 32

Attic 670 33

Apartment 350 30

Outdoor (exterior reference) 167 26

These conditions were documented on April 30, 2026. The building has been closed since, and conditions may have changed. Contractors should verify conditions during a site visit and price accordingly.

3. Scope of Work (Base Bid) The Contractor shall perform all work in accordance with the Protocol (Attachment B) and the current ANSI/IICRC S520 Standard for Professional Mold Remediation. Where this Invitation to Bid and the Protocol differ, the more stringent requirement applies. The Contractor provides all labor, supervision, materials, equipment, personal protective equipment, permits, and disposal. Lettered items below match the line items on the Bid Form.

A. Asbestos inspection and lead-safe practices. Before disturbing any building materials, the Contractor shall have materials to be disturbed inspected by a Colorado-certified asbestos building inspector, as applicable under Colorado Air Quality Control Commission Regulation No. 8, and provide the report to the Town. Any asbestos abatement found necessary is excluded from the base bid and will be handled by change order. Painted surfaces shall be handled with lead-safe work practices.

B. Work plan and submittals. Before mobilizing, submit a written work plan consistent with the Protocol, certificates of insurance, Safety Data Sheets for all chemicals, the respiratory protection program, and personnel certifications.

C. Setup, containment, and environmental controls.

1. Erect full-scale containment with zipper entries at the employee kitchen and at the crawlspace access. Containment remains in place until final passed clearance.

2. Post 8" x 10" yellow signs with black lettering reading "Remediation in Progress" at every building entrance and exit, legible from 10 feet, with the Contractor's point of contact and emergency contact. Post "Authorized Personnel Only" signs at containment entries.

3. Disable the HVAC system and seal all supply and return vents with polyethylene sheeting of at least 6 mil before work begins.

4. Operate HEPA-filtered air scrubbers under negative pressure, placed as the Contractor determines.

5. Operate at least two dehumidifiers (one in the crawlspace, one in the employee kitchen) from the completion of containment until 12 hours before clearance testing. Keep relative humidity below 45% throughout the structure at all times.

6. Check and log dehumidifier operation, temperature, relative humidity, and moisture readings at least every 24 hours.

D. Contents handling. Remove all contents from the employee kitchen. Photograph, inventory, pack, HEPA-vacuum, and treat them with an EPA-registered antimicrobial. Store them in a safe, dry, climate-controlled location until clearance and restoration, then return them. The bid shall state where contents will be stored.

E. Employee kitchen remediation. Remove and dispose of all contaminated building materials, including the sink base cabinet and other affected cabinetry, countertop, subfloor, and wall materials. HEPA-vacuum and damp-wipe all exposed framing, sheathing, and surfaces with an EPA-registered antimicrobial (the Protocol recommends Bio Cide 100).

F. Crawlspace and foundation remediation.

1. Remove debris, loose or contaminated insulation, foam board, and other contaminated materials from the crawlspace.

2. HEPA-vacuum and damp-wipe with antimicrobial all wood framing, floor joists, sills, posts, the underside of the subfloor, and foundation walls.

3. Install a new vapor barrier of 12 to 18 mil across the crawlspace floor, secured in place for clearance inspection. No vapor barrier currently exists.

G. Whole-building cleaning. HEPA-vacuum and damp-wipe with antimicrobial the interior surfaces listed in the Protocol, including walls, doors, ceilings, closets, outlets, switches, fixed light fixtures, and windows, throughout the building. HEPA-vacuum all flooring and clean or treat rugs and carpets.

H. Waste handling and disposal. Bag contaminated materials in 6-mil bags filled no more than three-quarters full, then double-bag. Dispose of them in an exterior dumpster provided by the Contractor, on site before work starts and until restoration is complete.

I. Restoration of the employee kitchen. Replace removed cabinetry, countertop, sink, and fixtures with like-kind materials approved by the Town, and restore the room to its pre-remediation condition.

Plumbing reconnection shall be performed by a Colorado-licensed plumber.

J. HVAC inspection and cleaning. Inspect the HVAC unit, ductwork, and vents. After passed clearance, clean the system in accordance with NADCA standards and replace all filters with MERV 7 or higher. This work may be performed by a licensed HVAC subcontractor.

K. Logs, documentation, and closeout. Keep a current copy of the work plan and Protocol on site.

Maintain daily sign-in and sign-out sheets, daily moisture and humidity logs, and a photo log of the work. Deliver all logs and photos to the Town and the Indoor Environmental Professional within one business day of passed clearance.

L. Clearance coordination. Notify the Town and the Indoor Environmental Professional at least 48 business hours before clearance sampling. If an area fails clearance, the Contractor shall re-clean it as directed and pay the cost of retesting until clearance is achieved.

4. Alternates and Unit Prices Alternates are optional and are priced separately from the base bid. The Town may accept any, all, or none of them. The low bid is determined on the total base bid plus any alternates the Town elects to accept, applied the same way to every bid. A bidder may leave an alternate blank, which means that alternate is not offered.

• Alternate 1, Crawlspace dehumidification: furnish and install a permanent, drained crawlspace dehumidifier sized for the crawlspace, after clearance.

• Alternate 2, Crawlspace encapsulation: extend and seal the vapor barrier up the foundation walls and around posts, beyond the base floor vapor barrier in Item F.

• Alternate 3, Crawlspace water management: furnish and install an interior perimeter drain and sump pit with pump, discharging away from the building. This alternate is subject to review by the Town's engineer.

Unit prices on the Bid Form will be used to price additional work for hidden or added conditions found during the project. Additional work proceeds only by written change order as described in Section 9.

5. Work by the Town and Others

• Clearance testing. The Town's Indoor Environmental Professional, Mold Test Company, will perform post-remediation visual inspection, moisture and humidity readings, and sampling, and will issue the clearance letter. The Town pays for the first clearance; the Contractor pays for any retesting after a failed clearance.

• Source correction. The Protocol requires that moisture sources be addressed before remediation. The Town will separately engage a Colorado-licensed structural engineer for the crawlspace and foundation and a licensed plumber for the kitchen. The notice to proceed will be coordinated with that work.

• Independence. The Contractor shall have no ownership, employment, or financial relationship with Mold Test Company or its inspectors.

• Access and utilities. The Town will provide building access, electrical power, and water at no charge. The Contractor is responsible for confirming electrical capacity and supplying any temporary power needed.

6. Bidder Qualifications, Insurance, Bonds, and Permits Under Section 8 of the Bidding and Purchasing Policy, a bidder must show the resources, experience, record of performance and integrity, and legal capacity needed to complete the work. Colorado does not license mold remediation contractors, so the Town sets the following minimum qualifications.

• The on-site supervisor holds a current IICRC Applied Microbial Remediation Technician (AMRT) certification or an equivalent mold remediation certification.

• The firm has at least three years of mold remediation experience and three references from commercial or public-sector projects completed in the last five years.

• The firm maintains an OSHA-compliant respiratory protection program with fit testing, a hazard communication program, Safety Data Sheets for all chemicals on site, lockout/tagout procedures, and fire extinguishers on site. No one with facial hair that prevents a respirator seal may wear a tight-fitting respirator or enter work areas.

• The Contractor is solely responsible for site safety, security, damages, contamination, citations, permits, notifications, and waste disposal.

• Plumbing work is performed by a Colorado-licensed plumber and electrical work by a Colorado-licensed electrician, under State plumbing and electrical permits and inspections through the Colorado Division of Professions and Occupations where required.

• The Contractor holds a current Town of Crestone business license (Municipal Code Section 6-1-

20) before work begins.

Insurance. Before the notice to proceed, the Contractor shall provide certificates of insurance naming the Town of Crestone, its officers, and employees as additional insureds on the general liability, auto, and pollution policies.

Coverage Minimum limit

Coverage Minimum limit

Commercial general liability $1,000,000 per occurrence; $2,000,000 aggregate

Automobile liability $1,000,000 combined single limit

Workers' compensation Colorado statutory limits

Contractor's pollution liability, including mold and fungi

$1,000,000 per occurrence

Bonds. No bid security is required. If the contract price exceeds $50,000, the Contractor shall deliver a performance bond and a payment bond, each equal to 100% of the contract price and issued by a surety authorized to do business in Colorado, before the notice to proceed, as required by Section 13 of the Bidding and Purchasing Policy and C.R.S. 38-26-106. For a contract of $50,000 or less, the Purchasing Officer waives the bond requirements under Section 13(a) of the Policy.

Retainage. If the contract price exceeds $25,000, the Town will retain 10% of the value of completed work from each partial payment, not to exceed 5% of the contract price, until the entire contract is complete, as required by Section 13(c) of the Policy.

7. Site Visits, Questions, and Addenda

• Site visits. The building is closed, so visits are by appointment only between October 26 and

November 6, 2026. Request a time by email to crestonetownoffice@gmail.com with the subject line "ITB 2026-01 Site Visit." Visits are strongly recommended but not mandatory. Bring your own respiratory protection and lighting; crawlspace access is tight.

• Questions. Submit all questions in writing by email by Friday, November 6, 2026 at 4:00 p.m.

MT. Answers will be posted as addenda on BidNet Direct so every bidder receives the same information. Oral answers are not binding.

• Addenda. Bidders are responsible for checking BidNet Direct for addenda and must acknowledge each one on the Bid Form.

• Communication. From posting until award, contact about this Invitation to Bid goes only to the Purchasing Officer named in Section 1. Contacting Trustees or other Town officials about it may disqualify a bid.

8. Sealed Bid Submission and Public Opening Sealed bids must be received by Friday, November 13, 2026 at 2:00 p.m. MT. Late bids will not be opened. Bids may be submitted in either of two ways:

1. Electronically through BidNet Direct, which holds bids sealed until the opening time.

2. In a sealed envelope mailed to Town of Crestone, Attn: Purchasing Officer, P.O. Box 64, Crestone, Colorado 81131, marked on the outside "SEALED BID: ITB 2026-01, Town Hall Mold Remediation. DO NOT OPEN." Mailed bids must be in the post office box by the deadline.

Bids sent by email will not be accepted. A bidder may modify or withdraw its bid by written notice received before the opening time.

Public opening. At 2:00 p.m. MT on November 13, 2026, the Purchasing Officer will open all bids publicly by video conference in the presence of at least one witness and read aloud each bidder's name and total base bid. The link will be posted on BidNet Direct. Bidders and the public are encouraged to attend. No statement will be made about a winning bid at the opening or at any time before award.

Each bid shall include:

Saguache County business address.

10. A completed IRS Form W-9.

Bids remain valid for 90 days after the opening. Bids are accepted as submitted. A bid that adds conditions, qualifications, or exceptions to this Invitation to Bid or the Protocol may be rejected as nonresponsive.

9. Evaluation, Award, and Contract Terms The contract will be awarded to the lowest responsive and responsible bidder, as provided in Section 6(g) of the Bidding and Purchasing Policy. Responsibility is judged under Section 8 of the Policy, including qualifications, references, and the ability to meet the insurance, bond, and Protocol requirements.

Because the work is expected to exceed $5,000, the Purchasing Officer will submit the recommended award to the Board of Trustees for final approval in an open meeting. The award is made by written notice to the successful bidder.

• Local preference. Under Section 14 of the Policy, a business located or based in Saguache County will be awarded the contract if its bid is within 3% of the lowest responsible bid from a non-local bidder. If the two lowest responsible bidders are both local, the lower bid is awarded.

If a local bidder does not carry workers' compensation insurance, the Town may provide it and add that cost to the local bid for comparison.

• Reserved rights. The Town may cancel this Invitation to Bid or reject any or all bids, in whole or in part, when in the Town's best interest (Policy Section 7), and may reject all bids if the lowest qualified bid exceeds the budget. The Town may award the base bid with or without alternates and may waive minor informalities.

• Bids over available funds. If the lowest responsive and responsible bid exceeds available funds and time or economic considerations preclude resoliciting a reduced scope, the Town may negotiate an adjustment of the bid price with that bidder to bring it within available funds (Policy Section 6(g)).

• Bid mistakes. After the opening, a bid may be corrected only as allowed by Section 6(f) of the Policy.

• Agreement. The successful bidder shall sign a written agreement prepared by the Town before work begins. This Invitation to Bid, any addenda, and the Protocol are incorporated into it.

• Appropriation and change orders. As required by C.R.S. 24-91-103.6, the agreement will state that the money appropriated for the project equals or exceeds the contract amount. No change order or other modification that increases the contract price beyond the appropriation may be issued unless the Contractor first receives written assurance that additional funds have been lawfully appropriated and are available. Obligations beyond the current fiscal year are subject to annual appropriation.

• Payment. Invoices are paid after Board approval at a regular meeting, less any retainage under Section 6. Remediation items are payable after the passed clearance letter and delivery of logs and photos. Restoration and HVAC items are payable on completion.

• Colorado labor. As required by C.R.S. 8-17-101, Colorado labor shall perform at least 80% of each type or class of labor on the project, unless the Town grants a waiver allowed by that statute.

• Final settlement. If the contract exceeds $150,000, the Town will publish notice of final settlement under C.R.S. 38-26-107 before final payment.

• Sales tax. The Town is exempt from Colorado sales tax. The successful bidder may apply for a Colorado contractor's exemption certificate for materials incorporated into the project, and bids should exclude state sales tax.

• Warranty. The Contractor guarantees the remediation will achieve clearance and warrants restoration workmanship for one year from completion.

• Ethics. Bidders are bound by Division 5 of the Policy, including the prohibitions on gratuities, kickbacks, and contingent fees. Violations may result in rejection of the bid, termination of the contract, or debarment.

• Public records. All bids become public records. Trade secret or confidential financial information must be clearly marked, and the Town will handle it as allowed by the Colorado Open Records Act.

• Other terms. The Town is not responsible for any cost of preparing a bid. Nothing in this Invitation to Bid waives the protections of the Colorado Governmental Immunity Act. This Invitation to Bid does not create any right to receive an award (Policy Section 2).
