<br />We have reviewed the low bid information submitted by the Corval Group and requested,
<br />received and reviewed additional information in regards to the Quality Assurance requirements of
<br />Section 131811.1.02.A.1 that states the following.
<br />
<br />1. As evidence and assurance of the contractor’s ability to construct the project and support the
<br />Owner’s system with service the contractor installing and constructing the primary and
<br />secondary refrigeration systems must have successfully installed and constructed AMMONIA
<br />refrigeration systems for five (5) ice rink construction projects that are similar to this project
<br />and completed within the past five (5) years. Submit information on each project. Submittal
<br />shall be on company letterhead, signed by an authorized representative of the company and
<br />include project description, portion of project completed by the company, location,
<br />construction cost, completion date, owner's name, owner's representative, phone number
<br />and completion date of work.
<br />
<br />The Corval Group listed one ice rink project, constructed seven (7) years ago, where they stated a
<br />new compressor room and rink floor were installed for $196,726. They listed four (4) other ice
<br />rink facilities where they had maintenance and service contracts ranging in total value from
<br />$50,000 to $200,000 each for a 3-5 year period between 2017-2022. It was confirmed with the
<br />Corval Group that the work listed for these four (4) ice rink projects was maintenance and service
<br />type work and not new equipment installation. They provided information on other industrial
<br />grade ammonia projects completed in the last five (5) years that are not ice rink related projects.
<br />Based on the information that the Corval Group has provided, it does not meet the requirements
<br />or intent of Section 181811.1.02.A.1.
<br />
<br />We have also reviewed the bid information submitted by Total Mechanical Services, Inc. and find
<br />no irregularities that would cause us to be concerned with their bid. They have experience with
<br />this type of specialty work, and they are using experienced subconsultants.
