Specifications include, but are not limited to: Indoor Air Quality During Construction Lessor must comply with the following requirements when renovations occur while any portion of the Premises is occupied by Lessee: The Lessor shall sequence the installation of finish materials so that materials that are high emitters of volatile organic compounds (VOCs) are installed and allowed to cure before installing interior finish materials, especially soft materials that are woven, fibrous, or porous in nature, which may adsorb contaminants and release them over time. Where demolition or construction work occurs in the leased space or adjacent to the Premises, the Lessor shall erect appropriate barriers (noise, dust, odor, etc.) and take necessary steps to minimize interference with the occupants. This includes maintaining acceptable temperature, humidity, and ventilation in the occupied areas during window removal, window replacement, or similar types of work. HVAC During Construction: If air handlers are used during construction, the Lessor shall provide filtration media with a minimum efficiency reporting value (MERV) of 8 at each return air grill, as determined by the latest edition of American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 52.2, Method of Testing General Ventilation Air Cleaning Devices for Removal Efficiency by Particle Size. The permanent HVAC system may be used to move both supply and return air during the construction process only if the following conditions are met: a. A complete air filtration system with 60 percent (60%) efficiency filters is installed and properly maintained. b. No permanent diffusers are used. c. No plenum type return air system is employed. d. The HVAC duct system is adequately sealed and isolated from the occupied area to prevent the spread of airborne particulate and other contaminants. e. Following the building “flush out,” all duct systems are vacuumed with portable high-efficiency particulate arrestance (HEPA) vacuums and documented clean in accordance with National Air Duct Cleaners Association (NADCA) specifications. Flush-Out Procedure: a. A final flush-out period of seventy-two (72) hours minimum is required after installation of all interior finishes and before occupancy of the space. The Lessor shall ventilate twenty-four (24) hours a day, with new filtration media at 100 percent (100%) outdoor air (or maximum outdoor air while achieving a relative humidity not greater than 60 percent (60%). b. After the three (3) day period the Premises may be occupied; however, the flush out must continue for thirty (30) days using the maximum percentage of outdoor air consistent with achieving thermal comfort and humidity control. c. Any deviation from this ventilation plan must be approved by the Lessee. d. The Lessor is required to provide regularly occupied areas of the Premises with new air filtration media before occupancy that provides a MERV of 13 or better. e. During construction, meet or exceed the recommended design approaches of the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) IAQ Guideline for Occupied Buildings Under Construction, 1995, Chapter 3. f. Protect stored onsite and installed absorptive materials from moisture damage. 3.2.2 Lessor Design/Construction Milestones Design and construction activities for the Premises shall commence upon Lease Execution. The Lessor shall include the following activities to achieve timely completion of the work required by this Lease: a. Develop preliminary floor plan and test fit for review by the Using Agency. b. Preliminary Design Site visit with Using Agency to verify design and existing conditions. c. Coordinate furniture plan, voice/data, and security/access control system with architectural plans prior to final design. d. Coordinate design review meetings, as needed. e. Prepare final architectural drawings/construction documents. f. Provide final architectural floor plan to Using Agency for final review and approval. g. Coordinate design review meetings as needed. h. Submit final architectural drawings for permit application process. i. Provide shop drawings/submittals to Using Agency for review. j. Prepare construction schedule identifying the critical construction progress milestones for each discipline. k. Coordinate pre-construction meeting with Lessee. l. Execute all phases of construction activities with all trades and/or vendors. m. Coordinate substantial completion inspection (punch list) with Lessee, architect, and contractors (thirty [30] days prior to acceptance inspection). n. Obtain Certificate of Occupancy. o. Coordinate final acceptance inspection with Lessee for Lease commencement (thirty [30] days after substantial completion inspection). p. Complete any remaining punch list items within thirty (30) days of acceptance inspection. 3.2.3 Construction Documents The Lessor's Construction Documents (CDs) shall include all mechanical, electrical, plumbing, fire protection, life safety, lighting, structural, security, and architectural improvements scheduled for inclusion into the Premises. The CDs shall be annotated with all applicable specifications. The CDs shall also clearly identify Tenant Improvements (TIs) already in place and the work to be done by the Lessor or others. Notwithstanding the Lessee's review of the CDs, the Lessor is solely responsible and liable for their technical accuracy and compliance with all applicable Lease requirements. The Lessor shall provide Computer Aided Design (CAD) drawings in DWG format of the architectural layout of the space to the Lessee upon request so that furniture layouts can be conducted.
