Proposal for Façade Consulting The Gateway Center 228 Churton St. Hillsborough, NC 27278 BECS #20250551 August 27, 2025 BECS is now a Lerch Bates Company Firm License Number: P-2493 WeAreBECS.com · LerchBates.com locations through the Management office to occur during normal business hours (Monday through Friday, 9:00 AM to 4:00 PM). If required, the Owner or property manager may arrange for an escort to accompany us during our site visit. • We will perform a forensic leakage investigation to determine the causes and pathways of water intrusion and air infiltration. During this investigation, we will use calibrated testing equipment to create a pressure differential between the interior and exterior; utilizing a blower door. This will effectively create a wind-driven rain event, which will provide for more efficient means of leakage detection. Isolation techniques described in ASTM E2128 will be utilized to isolate certain joints and conditions. This will help us to determine more specific pathways of water and air intrusion. This can help to rule out certain repairs that may not be necessary. An Aerial Lift will be required to access elevated areas of concern. Bulk exterior smoke testing will also be used to evaluate potential excessive air infiltration. • Investigative probes requiring exterior brick removal in three locations will be performed by a subcontracted contractor. In addition, a section of parapet metal coping will be removed and replaced by the contractor. The probes are to identify potential deficiencies in the construction of the backup wall and transitions i.e. windows, shelf angle etc. • We will take interior temperature and humidity measurements and perform a hygrothermal WUFI computer simulation if necessary to assist in our analysis. • We will follow up on our study with a detailed report Our findings will include recommendations, practical repair solutions to address the observed conditions, risk factors associated with the observed conditions, and recommendations for additional testing or exploratory openings (if necessary) to better und erstand the reported conditions. A stamped and sealed report can be provided upon request for an additional cost . • We will attend one in-person or virtual meeting during regular business hours (Monday through Friday, 10:00 AM to 3:00 PM) with the Client and Client’s representative following delivery of our findings to review conditions and recommendations and answer questions related to the study. If, during our work, we discover conditions that require immediate attention/repairs or additional access to perform detailed observations and intrusive investigation, we will inform you of our findings and provide a budget for the additional work. We will not proceed with additional work without first receiving written approval from the Client. Upon review and discussion with the Owner’s representative, BECS can provide a proposal for preparing design and specification documents, permitting assistance, performing bidding, and providing quality assurance services for the project remediation. TASK 2 – DESIGN DOCUMENTS • BECS will complete a Building Code Analysis for the project. This will establish the regulatory criteria for the project and develop our design in compliance with local Permit Authority requirements. Our analysis will be limited to only those portions of the Building Code applicable to the scope of our design work. • BECS will prepare technical Specifications and Drawings (together referred to as the “Project Manual”) to scope and describe repair or replacement needs for the components in question in sufficient detail for competitive bidding or pricing by the Client’s pre-selected Contractor. The content, Level of Detail, and Design Intent of the Project Manual will be based on the scope agreed to by the Client. Docusign Envelope ID: FC887B74-13D0-4575-BB1C-E4A9D8E29E85
