Transcription

1 PART 1 - GENERAL 1.1 SUMMARY A. Section includes: Execution requirements. B. Related Requirements: 1. Specification Sections 2 through 49. PART 2 - PRODUCTS (Not Used). PART 3 - EXECUTION 3.1 SAFETY A. Safety and supervision of construction procedures are Contractor's responsibility as stated in the General Conditions. Neither the Associate Architect nor his consultants claim expertise in, and take no responsibility for, construction means and methods or job site safety during construction. Processing and approving submittals made by Contractor which may contain information related to construction methods or safety issues, or participation in meetings where such issues might be discussed must not be construed as voluntary assumption by the design professional of any responsibility for safety procedures. 3.2 EXAMINATION A. Existing Conditions: The existence and location of site improvements, utilities, and other construction indicated as existing are not guaranteed. Before beginning work, investigate and verify the existence and location of mechanical and electrical systems and other construction affecting the Work. 1. Before construction, verify the location and points of connection of utility services. B. Existing substrates: Examine the substrate or structure to which a product is to be applied or installed. Do not proceed until unsatisfactory conditions have been corrected. Starting the Work indicates acceptance of conditions and the installer assumes full responsibility for results. 1. Check the substrate or structure for proper clearances and tolerances. Tolerances may be listed under individual Sections. 2. Verify compatibility with and suitability of substrates, including compatibility with existing finishes or primers. 3. Examine roughing-in for mechanical and electrical systems to verify actual locations of connections before equipment and fixture installation. 4. Examine walls, floors, and roofs for suitable conditions where products and systems are to be installed. 3.3 PREPARATION A. Field Measurements: Take field measurements as required to fit the Work properly. Recheck measurements before installing each product. Where portions of the Work are indicated to fit to other construction, verify dimensions of other construction by field measurements before fabrication. Coordinate fabrication schedule with construction progress to avoid delaying the Work. B. Space Requirements: Verify space requirements and dimensions of items shown diagrammatically on Drawings

2 C. Substrates: Where products are applied to an existing or new substrate, prepare the substrate as recommended by the product Manufacturer, generally as follows: 1. Bring substrate to a uniform surface by smoothing uneven surfaces and filling holes, cracks and low places with recommended filler or parent material. 2. Depressed Slabs: Bring substrate to required elevation to receive finish materials where finish materials cannot completely fill depression. Use approved cementitous filler or parent material. Coordinate depressed slab locations with finish material locations. 3. Remove substances, such as dust, oils and other foreign matter, not compatible with the product. 4. Surfaces shall be dry, unless a moisture content or wetting is specified. D. Floor preparation for installation of finish flooring materials: The General Trades Contractor shall provide all major floor preparation for floor finishes, including preparation for resilient flooring and carpet floor finishes furnished and installed by the University. Floor preparation shall include the following: 1. Following removal of the existing flooring materials and adhesives, clean, repair and prepare subfloor surfaces to receive new floor finishes. Remove surface irregularities that would telegraph to the finish floor surface. Grind ridges and raised areas. Fill holes and depressions and repair cracks. Subfloor surfaces shall be clean, smooth, level with not more than 1/8" in 10'-0" variation, free of holes, depressions and cracks and suitable to receive resilient and carpeting finish flooring materials. 2. Filling all holes in existing and new concrete floor slabs. 3. Filling and patching trenches in existing and new concrete floor slabs after the trenches are cut and filled. 4. Cleaned and repaired subfloor surfaces will be inspected and shall be acceptable to the University before installation of finish flooring materials. E. Inserts and Anchorages: 1. Anchorages where not detailed are the responsibility of the installer to design a suitable connection, structurally sound, and aesthetically acceptable to the Associate. Furnish calculations, drawings, product data when requested by Associate Architect. 2. It is the responsibility of the installer to furnish built in fastening devices for their product to the proper trade for installation as the Work proceeds. 3. In the event such devices are not furnished in time to be built in, it is the installer's responsibility to provide other methods for attaching their product. Submit Drawings and other required data to the Associate Architect. F. Templates: Provide templates, diagrams and other coordinating documents to the proper Contractor, Manufacturer, or supplier of related items affecting the Work. G. Dimensions: 1. If the exact location of an item is not indicated by dimension on the Drawings or noted in the Specifications, the Associate reserves the right to determine such location in the field prior to roughing in. 2. If the exact dimensions of a product are not indicated or shown, the Associate Architect reserves the right to determine dimensions prior to ordering or fabricating the product. 3. Such dimensional changes shall not be a basis for changes in the Contract Amount. 4. Where miscellaneous devices, such as thermostats, switches, controls, grilles, pipes, or outlets of any nature are not exactly located by the Contract Documents, request such location or obtain approval of the location prior to installation. If approval has not been obtained, the Associate may direct the relocation of such devices at the expense of the installer. 3.4 CONSTRUCTION LAYOUT A. Verification: Before proceeding to lay out the Work, verify layout and work point information shown on Drawings, in relation to the property survey and existing benchmarks. If discrepancies are discovered, notify Associate Architect promptly

3 B. Building Lines and Levels: Locate and lay out control lines and levels for structures, column grids, and floor levels, including those required for mechanical and electrical work. Transfer survey markings and elevations for use with control lines and levels. 3.5 INSTALLATION A. Install products in accordance with the Manufacturer's recommendations or the requirements of trade associations, listed standards, approved Shop Drawings, and Contract Documents. 1.
