B, 3rd Floor Office 10 <br />Hillsborough, NC 27278 <br /> <br />Attention: Angel Barnes, Capital Projects Manager <br /> <br />Reference: Southern Human Services Center Roof and HVAC Renovations <br />Proposal for Additional Commissioning Services <br /> <br />Dear Ms. Barnes <br /> <br />From January of 2024 through June of 2024, MBP performed on-site functional performance testing <br />(FPT) and conducted TAB verification for the primary and secondary HVAC systems at the facility. <br />Stephen Cressionnie, CBCP, conducted and witnessed these tests. <br />Several issues have led to significant delays in testing and verification, prompting the need for a change <br />order. The core problems center around challenges with personnel proficiency and a lack of internal <br />quality control. Below is a summary of the causes for the delays: <br /> <br />1. Lack of Personnel Proficiency: It appears that the personnel provided for FPT support lacked the <br />necessary expertise. On multiple occasions, the contractor was not able to demonstrate (in a <br />timely manner) various features or functions of the system. Additionally, outside support was <br />required to resolve some of the issues identified during testing. These shortcomings have <br />resulted in a delay in the planned completion of the RTUs and VAVs. <br />2. Lack of Internal Quality Control: It appears that no quality control checks have been performed <br />to verify functionality of equipment and sequences prior to MBP’s arrival on-site. <br />3. Errors and inconsistencies in documentation with results that were not repeatable given the <br />same conditions. <br />4. Issues Log Updates: Issues in the Cx Issues Log have been updated to “Complete – Ready for <br />Review,” but were found to be unchanged or have only been partially addressed. MBP has had <br />to revisit issues multiple times to achieve closure. <br /> <br />REQUESTED AMENDMENT 2 <br /> <br />For the increased amount of time required to complete testing and verification on this project, MBP <br />requests an amendment to our contract on an hourly basis at a rate of $205.50. Estimated time to <br />complete testing and back checks for the remaining systems 34 hours. Total requested contract <br />modification for these additional services is as follows: <br /> <br />• Budgeted hours to complete FPT: 58 hours <br />• Budgeted hours to review TAB reports: 14 hours <br />• Budgeted hours to complete TAB verification: 20 hours <br />Docusign Envelope ID: FA1878AB-D9A0-437D-AAAB-A7D33A96CC56
