963 Code of Massachusetts Regulations 2.04 General Site and School Construction Standard
The Eligible Applicant shall make all reasonable efforts to ensure that an Approved Project, including those for the expansion or renovation of an existing building, meet all applicable federal, state, local and regional building code requirements. It shall be the responsibility of the Eligible Applicant to ensure compliance with all such building code requirements, and the Authority shall bear no responsibility for an Eligible Applicant's failure to comply with said requirements. (2) Design and Construction Standard: Indoor Air Quality. An Eligible Applicant shall make all reasonable efforts to ensure suitable indoor air quality in an Approved Project. Without regard to any other contract provisions, an Eligible Applicant shall meet the following indoor air quality requirements, to the extent that they apply to an Approved Project, as determined by the Authority. (a) New heating, ventilating and air conditioning systems shall meet the minimum ventilation rate requirements of American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Standard 62.1, Ventilation for Acceptable Indoor Air Quality, in effect at time of project approval. (b) New heating, ventilating and air conditioning systems shall comply with ASHRAE standard 55 for thermal comfort within established ranges per climate zone, in effect at time of project approval, except that winter humidification and summer dehumidification shall not be required. (c) Eligible Applicants shall implement containment procedures for dusts, gases, fumes, and other pollutants created during construction of an Approved Project if the building is occupied by students, teachers or school department staff while such renovation and construction is occurring. Such containment procedures shall be consistent with the IAQ Guidelines for Occupied Buildings Under Construction published by the Sheet Metal and Air Conditioning Contractors National Association, Inc. (SMACNA), in effect at time of project approval. All bids and proposals received for an Approved Project shall include the cost of planning and execution of containment of construction/renovation pollutants consistent with such SMACNA guidelines. (d) On all Approved Projects involving the installation of new ductwork, HVAC supply and the return openings shall be sealed to protect them from dust infiltration during construction. Procedures shall be consistent with the Duct Cleanliness for New Construction Guidelines published by SMACNA, in effect at the time of project approval relative to advanced levels of cleanliness which provide in part that ductwork shall be sealed when transported to the construction site; ductwork shall be stored in clean, dry conditions and kept sealed while stored; internal surfaces of ductwork shall be wiped-down immediately prior to installation to remove dust; open ends on completed ductwork and overnight work-in-progress shall be sealed; and uninstalled ductwork shall be protected from construction dust using surface wrapping. (e) Filtration media in ventilation equipment shall be replaced with new media immediately prior to occupancy. Filtration media shall have a Minimum Efficiency Reporting Value (MERV) such that mold spores and similarly sized particles are excluded from supply air intakes.
