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 Subcontractors 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(d): 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". 010700 — Page 1 of 2 © 2014 Building Envelope Technology & Research Westfield Southcenter Mall - Tukwila, Washington Reroofing Project - Roof Area J-3A Fall 2014 Section 010700 Abbreviations and Definitions PERMIT SET 6.

Owners Representative: Wesffield Southcenter Mall, authorized Project Representative: 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. In some instances Manufacturers use the term Guarantee to describe no dollar limit full system coverage. 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.
