Re: Protest Letter
Dear Mr. Tauscher,
This is to protest the Bid submitted by MEP Fusion Inc. to the City of Newport Beach on the above-referenced project.
The bidder did not meet the requirements for the following reasons:
- Contractor did not comply with the bidding documents by not listing an approved subcontractor.
Per the bid document “Designated subcontractors’ affidavit” and public code:
Designated Subcontractors Affidavit: “State law requires listing of all subcontractors who will perform work in an amount in excess of one half of one percent of the contract total bid. If a subcontractor is not listed, the contractor represents that he/she is fully qualified to and will be responsible for performing that portion of the work.”
This is required by the subletting and subcontracting Fair Practice Act (Public contract code section 4100, et seq.) Any subcontractor who receives an amount over ½ of 1% (half of one percent) of the total cost of the bid proposal must be list ed on the designation of subcontractors for a bid to be responsive. Per California public works code (Subletting and Subcontracting [4100 - 4114] Ch. 195, Sec. 42.1) and per the bid documents.
In the case of Fusion MEP, any subcontracted work exceeding $630.00 (½ of 1% of the ir bid total) must be listed in PlanetBids and as stated under the Designated Subcontractors’ Affidavit as required by the City’s bid documents.
Certified Roofing Subcontractor.
Per Pre-Bid RFI responses dated October 27 (Questions 1.7, 1.8, 1.9, and 1.12), the existing roofing is under warranty.
Technical Specification Section 07 51 00, Paragraph 1.4E states: “Installer shall be licensed or otherwise certified by the manufacturer of the accepted roofing system to perform work requiring warranty coverage, including material and workmanship. ” (See Exhibits A & B)
Fusion MEP failed to list a C-39 licensed roofing subcontractor and does not hold the required roofing certifications.
Scope of Roofing Work
Per plan Sheet S3.1, Detail 1, a new wood platform—larger than the new DOAS unit—is required to be installed.
Sheet M0.01, Equipment Schedule, note #2 specifies a new curb for the DOAS unit.
Sheet M3.01, Detail #1, shows the roofing extending up to the top of the curb, indicating the need for new roofing over the p latform, new cricket per architectural drawings, and full integration with the DOAS curb.
The value of this scope clearly exceeds 0.5% of Fusion MEP’s total bid amount (see Exhibit C). As Fusion MEP is neither qualified nor licensed to perform this work and has not listed a C-39 subcontractor, their bid must be deemed non-responsive under both the Public Contract Code and the City’s bid requirements.

City of Newport Beach – Protest Letter
Certified Air Balance Subcontractor/Requirement.
Per the project manual, Section 23 05 93, Paragraph 1.5A: “TAB Contractor Qualifications: Engage a TAB entity certified by AABC.” (see Exhibit D).
Fusion MEP is not listed as an AABC-certified or approved member. Therefore, they were required to designate an approved and AABC - certified Air Balance subcontractor in their bid submission.
The air balance scope of work represents a significant portion of the mechanical system commissioning and testing effort, and its value clearly exceeds one-half of one percent (0.5%) of Fusion MEP’s total bid amount (see Exhibit E).
As Fusion MEP is neither certified to perform this specialized work nor listed an AABC -certified subcontractor to perform it, their bid fails to meet both the City’s bid requirements and the mandatory provisions of the California Public Contract Code §4100 et seq.
Accordingly, Fusion MEP’s bid must be deemed non-responsive.
Given the reason above and the city limited time and the complexity of this project, we believe the city should reject MEP Fusion bid as non- responsive as they did comply with the bid documents and the public code, and award the contract to the second low bidder, AC Pros Inc.
Thank you for your attention to this letter.
Sincerely,
Noam Ziv

3.5 PROCEDURES FOR CONSTANT-VOLUME AIR SYSTEMS
A. Adjust fans to deliver total indicated airflows within the maximum allowable fan speed listed by fan manufacturer.
1. Measure total airflow.
a. Where sufficient space in ducts is unavailable for Pitot-tube traverse measurements, measure airflow at terminal outlets and inlets and calculate the total airflow.
2. Measure fan static pressures as follows to determine actual static pressure:
a. Measure outlet static pressure as far downstream from the fan as practical and upstream from restrictions in ducts such as elbows and transitions.
b. Measure static pressure directly at the fan outlet or through the flexible connection. c. Measure inlet static pressure of single-inlet fans in the inlet duct as near the fan as possible, upstream from the flexible connection, and downstream from duct restrictions. d. Measure inlet static pressure of double-inlet fans through the wall of the plenum that houses the fan.
3. Measure static pressure across each component that makes up an air-handling unit, rooftop unit, and other air- handling and -treating equipment.
a. Report the cleanliness status of filters and the time static pressures are measured.
4. Measure static pressures entering and leaving other devices, such as sound traps, heat-recovery equipment, and air washers, under final balanced conditions.
5. Review Record Documents to determine variations in design static pressures versus actual static pressures.
Calculate actual system-effect factors. Recommend adjustments to accommodate actual conditions.
6. Obtain approval from Architect for adjustment of fan speed higher or lower than indicated speed. Comply with requirements in HVAC Sections for air-handling units for adjustment of fans, belts, and pulley sizes to achieve indicated air-handling-unit performance.
7. Do not make fan-speed adjustments that result in motor overload. Consult equipment manufacturers about fan- speed safety factors. Modulate dampers and measure fan-motor amperage to ensure that no overload will occur.
Measure amperage in full-cooling, full-heating, economizer, and any other operating mode to determine the maximum required brake horsepower.
B. Adjust volume dampers for main duct, submain ducts, and major branch ducts to indicated airflows within specified tolerances.
1. Measure airflow of submain and branch ducts.
a. Where sufficient space in submain and branch ducts is unavailable for Pitot-tube traverse measurements, measure airflow at terminal outlets and inlets and calculate the total airflow for that zone.
2. Measure static pressure at a point downstream from the balancing damper, and adjust volume dampers until the proper static pressure is achieved.
3. Remeasure each submain and branch duct after all have been adjusted. Continue to adjust submain and branch ducts to indicated airflows within specified tolerances.
C. Measure air outlets and inlets without making adjustments.
1. Measure terminal outlets using a direct-reading hood or outlet manufacturer's written instructions and calculating factors.
D. Adjust air outlets and inlets for each space to indicated airflows within specified tolerances of indicated values. Make adjustments using branch volume dampers rather than extractors and the dampers at air terminals. 10-27
PBK/250303 TESTING, ADJUSTING, AND BALANCING FOR HVAC 230593 (6)
1. Adjust each outlet in same room or space to within specified tolerances of indicated quantities without generating noise levels above the limitations prescribed by the Contract Documents.
