Executive Summary:
Sonoma County Public Infrastructure is seeking Board award of a construction contract in the amount of $164,788, to Matrix HG, Inc., for removal and replacement of high-efficiency boilers within the Central Mechanical Plan located at the County of Sonoma County complex. If approved, the replacement of the high-efficiency boiler at the Central Mechanical Plant will reduce operational costs and improve heating efficiencies across the county complex. The existing equipment is offline and decommissioned.
Discussion:
The Central Mechanical Plant (CMP) is located within the Sonoma County Administration campus. It plays an important role in providing conditioned water to forced air units across the central complex. The CMP utilizes a combination of chillers and boilers to generate conditioned water for temperature regulation within the central complex. While the chillers efficiently cool water, the boiler system is responsible for heating water when necessary.
However, the efficiency of the boiler system is compromised due to a defunct boiler that provides heating during moderately cool days. The unit operates at the lower end of the heat-demand curve, preserving the larger boilers for days when the demand is more significant. The replacement unit operates within a range of 6,000 to 6,000,000 Btu per hour. The other larger units operate at 30,000 to 10,000,000 Btu per hour. Efficiency is paramount in HVAC systems like those in the CMP, as it directly impacts operating costs and environmental sustainability. High-efficient boilers consume less fuel to produce the same amount of heat, leading to lower operational expenses and decreased carbon emissions. Therefore, replacing the defective unit and upgrading to a more efficient boiler will yield significant cost savings and environmental benefits.
Benefits of Replacing the High-Efficiency Boiler:
1. Reduced Fuel Costs: High-efficiency boilers utilize advanced technologies such as condensing heat exchangers and modulating burners to maximize fuel utilization. By replacing the broken boiler with a more efficient unit, fuel consumption can be significantly reduced, leading to substantial cost savings over time.
2. Improved System Efficiency: A more efficient boiler not only reduces fuel consumption but also enhances the overall efficiency of the CMP's heating system. By delivering consistent and precise heat output, the upgraded boiler ensures optimal performance of forced air units, thereby improving occupant comfort and system reliability.
3. Environmental Impact: Reducing fuel consumption through boiler upgrades results in lower greenhouse gas emissions, contributing to Sonoma County's sustainability goals. By embracing energy-efficient technologies, the County can mitigate its carbon footprint and promote environmental stewardship.
A procurement solicitation was issued on June 17, 2024, and proposals were publicly opened on July 23, 2024. Three (3) bids were received and deemed responsive: from Stephens Construction, Inc, Peterson Mechanical, Inc., and Matrix HG, Inc., in the amount of $329,750, $231,800, $164,788 respectively. MatrixHG was determined to be the lowest responsive and responsible bidder and accordingly is recommended for award of this important project.
