Description: This is a performance based scope of work (SOW). The contractor is encouraged to use Value Engineering in developing the necessary evaluation methods, inspection, corrective action and recommended approach to ensure the complete operation and functionality of all AHUs system components and DDC devices for the efficient use of economizers. 2 DESCRIPTION OF SERVICES Refer to Section 3 of this scope of work for the minimum requirements for each line item below. Item Description 001 AHU System Baseline Assessment and Evaluation 002 Engineering Evaluation Report and Design Approach 003 Architect and Engineering (A&E) Services 3 SPECIFIC PROJECT REQUIREMENTS The specific requirements in this section are intended to be used as a guide to note the minimum requirements to be evaluated for the system correction and proper operation. It is the contractor ™s responsibility to conduct a throughout review and evaluation of each AHU system components to meet necessary code inspection requirements and ensure full automatic modulation and operation. The contractor is encouraged to use Value Engineering in developing the necessary evaluation methods, inspection, corrective action and recommended approach to ensure the complete operation and functionality of all AHUs system components and DDC devices for the efficient use of economizers. 3.1 Item 001 - AHU System Baseline Assessment and Evaluation The objective of this item is to identify and verify operation of current AHUs system components and to document and establish all deficiencies to be corrected. Refer to attached AHUs list provided as reference. This item shall include at a minimum: 3.1.1 Outside Air (OA) grills and return air dampers shall be inspected for obstructions and all recommendations for cleaning, repair or replacement shall be noted in the scope line item 002. 3.1.2 The existing AHU field electronic control devices shall be verified that they are receiving a signal from the EMCS system. The components shall be checked to verify the unit is sending an output signal (electric or pneumatic) when commanded. 3.1.2.1 Main control valves, alarms and signals shall be remotely connected to the EMCS system. Existing DDC system is Andover and controls shall be able to directly communicate with this system without the use of any intermediary software interface. 3.1.3 The damper actuator (DDC or pneumatic) shall be checked for air leaks or hunting. The stoke of the device shall be verified for the full range of motion. 3.1.4 Linkages shall be inspected for wear, broken and loose connections. 3.1.5 The dampers shall be inspected for smooth operation and full closure. Conditions of binding or bent louvers shall be noted and recommendations for repairs also noted as part of scope line item 002. 3.1.6 The amount of outside air (CFM) and return air shall be measured and logged to determine the % outside air to ensure the minimum amount is being supplied. 3.1.7 Verify and validate AHU schematic configuration to be provided. Note and correct discrepancies with provided information. 3.1.8 Verify presence of actuators, current condition and identify if they are pneumatically operated, electronically operated, mechanically operated, and/or fixed. 3.1.9 Evaluate modulation capacity of dampers and condition. 3.2 Item 002 - Engineering Evaluation Report and Design Approach The objective of this item is to document the AHUs system components deficiencies found as part of scope line item 001 as well as the methodology used. In addition, this item shall include all recommendations and necessary approach to correct, repair and restore operation of these for energy efficiency devices. This report shall establish a baseline of current system condition and components (to be included, but not limited to AHUs, dampers, DDC, actuators, wiring, signals, etc). The report shall include a comprehensive narrative description of current system operation, report findings and recommendations. It shall also provide the necessary supporting documentation, associated site plan, checklists and pictures. This item shall include at a minimum: 3.2.1 Assessment approach and methodology used to evaluate all AHUs components 3.2.2 Outcome of scope of work paragraphs 3.1.1 thru 3.1.9 with proposed corresponding corrections and recommendations 3.2.2.1 Explain deficiencies found 3.2.2.2 Detail corrections and/or repair/replacement 3.2.2.3 Note and indicate the absence of system components, electrical and pneumatic connections necessary for the operation of economizers in the surveyed units. 3.2.3 Include schematic verification of existing AHUs ™ system configuration and components. 3.2.4 Include schematic verification of proposed AHUs ™ system configuration and components, if merited for some units, for the efficient use of economizers. 3.2.5 Establish clear design approach and any phasing requirements as per VA Medical Center master plan 3.3 Item 003 - Architect and Engineering (A&E) Services 3.3.1 This item shall comply with Section 4, Selected A/E Requirements. This item shall include at a minimum: 3.3.1.1 Detailed SOW and requirements for system correction, repair or replacement 3.3.1.2 Project Specifications 3.3.1.3 Certification requirements 3.3.1.4 Warranty requirements 3.3.1.5 Contract Drawings 3.3.1.6 Phasing requirements 3.3.1.7 Deductive alternates 3.3.1.8 Cost Estimate 3.3.1.9 Deduct Alternates (in both scope and cost estimate) 3.3.2 The final document submission shall bear the seal of the Registered Architect and Professional Engineer responsible for the final report. 3.3.3 Mechanical and electrical tie-ins shall be clearly shown on the construction documents if full damper replacement is recommended. The A/E shall perform careful mechanical, electrical, structural, environmental, etc. analysis to avoid any possible change order during construction. 4 SELECTED A/E REQUIREMENTS 4.1 Selected A/E firm shall visit the site before submitting his final proposal. Visits to the site shall be made by appointment with the Contracting Officer. A/E firm shall have a comprehensive knowledge, experience, facilities, instruments, expertise, equipment and personnel to develop all required documents for this study. 4.2 The A/E is required to perform all necessary inspection, survey and evaluation of the existing project site and related utilities, systems and associated distribution systems to produce a correct, complete and fully coordinated report, including data obtained, results, evaluations, design approach and Cost Estimate. 4.3 Site survey work shall consists of existing drawing verification, comprehensive research, investigation, evaluation and study of the existing systems, equipment, structure and utilities that will be tied to the AHUs and EMCS. 4.3.1 VA may provide an architectural as-built in DWG, FCD or DXF format as per A/E request, but does not warrant the 100% accuracy of the same.
