Drawings and general provisions of the Construction Contract, including Specifications and bidding requirements apply to the work of this Section. B. Technical publications, standards, and reference documents as outlined in individual Technical Specification Sections and as indicated on Drawings. 1.2 RELATED SECTIONS A. The terms defined in this specification section are used throughout the Project Documents. 1.3 DEFINITIONS A. Certain terms used generally throughout the specifications (and drawings) are hereby defined as follows: 1. Indicated: A cross reference to details, notes or schedules on the drawings, other paragraphs or sections in the specifications, and similar means of recording requirements in the Contract Documents. Where terms such as "shown", "noted", "specified", "scheduled", and are used in lieu of "indicated", it is for the purpose of helping the reader accomplish the cross reference, and no limitation of location is intended except as specifically noted. 2. Directed, Requested, etc.: Unless otherwise explained, terms such as "directed", "requested", authorized", "selected", "approved", "required", "accepted", and "permitted" mean "directed by the Consultant", "requested by the Consultant", etc. However, no such implied meaning will be interpreted to extend the Consultant's responsibility into the contractor's area of construction supervision. 3. Installer: The person(s) or entity engaged by the Contractor or his Subcontractor for the performance of a particular unit of work at the project site, including installation, erection, application, and similar required operations. It is a general requirement that Installers be knowledgeable and experienced in the work they are engaged to perform. 4. Approve: Where used in conjunction with the Consultant's response to submittals, requests, applications, inquiries, reports, and claims by the contractor, the meaning of the term "approved" will be held to the limitations of the Consultant's responsibilities and duties. In no case will "approval" by the Consultant be interpreted as an assurance to the Contractor that the requirements of the Contract Documents have been completely fulfilled. 5. Furnish: Except as otherwise defined in greater detail, the term "furnish" is used to mean "...supply and deliver to the project site, ready for unpacking, assembly and installation". 01070 — Page 1 of 2 © 2013 Building Envelope Technology & Research Westfield Southcenter Mall -- Tukwila, Washington Reroofing Projectj — Roof Area B-2 Summer / Fall 2013 Section 01070 Abbreviations and Definitions BID & PERMIT SET 6.

Owners Representative: Westfield Southcenter Mall authorized Project Representative (i.e., Christian Faltenberger, Facilities Manager). 8. Project Consultant: Building Envelope Technology & Research's consulting personnel. 9. Guarantee and Warranty: "Warranty" is generally used in conjunction with products manufactured or fabricated away from the project site, and "guarantee" is generally used in conjunction with units of work which require both products and substantial amounts of labor at the project site. The resulting difference is that warranties are frequently issued by manufacturers for a product or products or systems, and guarantees are typically issued by contractors to cover their installed work. 1.4 DRAWINGS, DIMENSIONS, AND MEASUREMENTS A. Wherever a detail is referenced and developed for a specific condition, same or similar detail shall apply to identical or similar conditions elsewhere on project even though not specifically referenced. B. Wherever the word "similar" occurs on the drawings, it shall be interpreted in its general sense and not as meaning identical, and all details shall be worked out in relation to their location and their connection and/or relationship with other parts of the work. C. The figured dimensions on the drawings or notes indicating dimensions shall be used instead of measurements of the drawings by scale, and shall be strictly complied with. D. No scale measurements shall be used as a means to dimension work, except on "full size" drawings specifically for dimensioning purposes.

After completing painting operations, use workers skilled in the trades involved to reinstall items that were removed. Remove surface -applied protection if any. b. Do not paint over labels of independent testing agencies or equipment name, identification, performance rating, or nomenclature plates. 3. Clean substrates of substances that could impair bond of paints, including dirt, . oil, grease, salt, and incompatible paints and encapsulants. 09911 — Page 8 of 11 © 2013 Building Envelope Technology & Research Westfield Southcenter Mall -- Tukwila, Washington Re -Roofing Project — Roof Area B-2 Summer / Fall 2013 Section 09911 Exterior Painting BID & PERMIT SET a. Remove incompatible primers and re -prime substrate with compatible primers as required to produce paint systems indicated. 4. Painted Surfaces: Remove old paint not tightly and fully bonded to the surface. Prepare substrate using published methods and as recommended in writing by paint manufacturer. a. Test patches (minimum of 3 ea.) shall be conducted to determine compatibility of primer over unknown previously -applied coatings. 5. Solvent Clean and Wipe: Clean all metal surfaces scheduled to paint with non - petroleum based solvents so surface is free of oil and surface contaminants. If a solvent is used, allow solvent sufficient time to fully flash -off prior to application of initial primer coat of specified coating. B. Preparation of Cast Iron Internal Drain Bowl Assemblies: Prior to refinishing, remove all rust, dirt and other foreign materials by power and hand wire brushing, from the existing cast iron roof drain bowl and flange surfaces, serviceable undamaged clamping rings, and the accessible portions of the interior of the drain nipple and leader, as feasible. C. Steel Surfaces: Prepare substrate in accordance with SSPC SP10/NACE 2 "Near White Metal Blast Cleaning".
