Omitted words and phrases shall be supplied by inference. Similar types of provisions may appear in various parts of a section or articles within a part depending on the format of the section. The Contractor shall not take advantage of any variation of form, format or style in making claims for extra Work.' 3.2.2. The cross referencing of specification sections under the subparagraph heading "Related Sections include but are not necessarily limited to:' and elsewhere within each specification section is provided as an aid and 00805-4 convenience to the Contractor.

Add a paragraph immediately after paragraph GC-6.4. which is to read as follows: 6.4.1. Where the Work requires equipment be furnished, due to the lack of standardization of equipment as produced by the various manufacturers, it may become necessary to make minor modifications in the structures, buildings, piping, mechanical work, electrical work, accessories, controls, or other work, to accommodate the particular equipment offered.

Amend the sixth sentence of paragraph GC-6.7.1.2. by deleting the word "Substantial." Add a new paragraph after paragraph GC-6.15., which is to read as follows: 6.15.1. Recent legislation has removed the sales tax exemption previously provided by Section 151.311 of the Tax Code covering tangible personal property purchased by a contractor for use in the performance of a contract for the improvements of City-owned realty. It is still possible, however, for a contractor to make tax-free purchase of tangible personal property which will be incorporated into and become part of a City construction project through the use of a "separated contract" with the City. A "separate contract" is one which separates charges 00805-10 for materials from charges for labor. Under such a contract, the contractor becomes a 'seller' of those materials which are incorporated into the project, such as bricks, lumber, concrete, paint, etc. The contractor issues a resale certificate in lieu of paying the sales tax at the time such items are purchased. The contractor then receives an exemption certificate from the City for those materials. (This procedure may not be used, however, for materials which do not become a part of the finished product. For example, equipment rentals, from materials, etc. are not considered as becoming 'incorporated' into the project). Utilization of this "separated contract" approach eliminates the need for bidders to figure in sales tax for materials which are to be incorporated into the project. The successful bidder's bid form will be used to develop the 'separated contract' and will determine the extent of the tax exemption. Upon execution of the construction contract, the contractor shall furnish a breakdown (per item) of 1) materials incorporated into the project; and 2) labor, equipment, supervision and materials not incorporated into the project. SC-6.19. Add the following language at the end of the first sentence of paragraph GC-6.1g: CONTRACTOR shall include accurate locations for buried and imbedded items. SC-6.ZO. Amend the last sentence of paragraph 6.20 to delete the word "Substantial.' SC-6.24. d 'required" to the first sentence of paragraph immediately after the words 'CONTRACTOR shall submit." At the end of paragraph GC-6.24.1., add the following paragraphs: 6.24.1.1. Shop Drawings submitted as herein provided by CONTRACTOR and reviewed by ENGINEER for conformance with the design concept shall be executed in conformity with the Contract Documents unless otherwise required by OWNER. 6.24.1.2. When Shop Drawings are submitted for the purpose of showing the installation in greater detail, their review shall not excuse CONTRACTOR from requirements shown on the drawings and Specifications. 00805-11 6.24.1.3. For-Information-Only-For-Future-Use submittals upon which the ENGINEER is not expected to conduct review or take responsive action may be so identified in the Contract Drawings. Add the word 'required' to the first sentence of paragraph GC-6.24.2., immediately after the words 'shall also submit.' At the end of paragraph GC-6.24.2., add the following paragraphs: 6.24.3. If a Shop Drawing or Sample, as submitted, indicates a variation from the Contract Requirements as set forth in the Contract Documents and ENGINEER finds same to be in the interest of OWNER and to be so minor as not to involve a change in the Contract Price or time for performance, ENGINEER may approve the Shop Drawings or Samples; provided however, such departure is slight in nature and does not affect the design concept of the Work. CONTRACTOR shall submit all Shop Drawings and Samples sufficiently in advance of construction requirements to allow ample time for checking, correcting, resubmitting and rechecking and to avoid any delay in progress of the Work. Add a new paragraph immediately after paragraph GC-6.24.3. which is to read as follows: 6.24.4. See Section 01340. SC-6.25. At the end of paragraph 6.25.3., delete 'Variation.' and add: "Variation; otherwise CONTRACTOR will not be relieved of the responsibility of executing the Work in accordance with the Contract Documents, even though such Shop Drawings or Samples have been otherwise reviewed.' Add the following paragraph at the end of paragraph GC-6.25.3: 6.25.4. Shop Drawings and Sample submittals not conforming to requirements of this paragraph 6.25 and Section 01340 will be returned to CONTRACTOR without action for resubmittal and the resulting delay shall be entirely the responsibility of CONTRACTOR. Add the following paragraph at the end of paragraph GC-6.25.4: 6.25.5. See Section 01340. SC-6.26.

Add the following paragraph at the end of paragraph GC-6.27: 6.27.1. ENGINEER's check and review of Shop Drawings and Samples, Specifications and descriptive literature submitted by CONTRACTOR will be only for general conformance with design concept, except as otherwise provided, and shall not be construed as: 6.27.1.1. permitting any departure from the Contract Requirements; 6.27.1.2. relieving CONTRACTOR of the responsibility for any error in details, dimensions or otherwise that may exist in such submittals; 6.27.1.3. constituting a blanket approval of dimensions, quantities, or details of the material or equipment shown; or 6.27.1.4. approving departures from additional details or instructions previously furnished by ENGINEER.

Add the following new paragraph 7.5 immediately after paragraph 7.4: 7 Should CONTRACTOR cause damage to the work or property of any separate Contractor at the site, or should any claim arising out of CONTRACTOR's, OWNER, ENGINEER, Consulting Engineer or any other person, CONTRACTOR shall promptly attempt to settle with such other Contractor by agreement, or to otherwise resolve the dispute by arbitration or at law. CONTRACTOR shall, to the fullest extent permitted by Laws and Regulations, indemnify and hold OWNER, ENGINEER, and Consulting Engineer harmless from and against all claims, damages, losses and expenses (including, but not limited to, fees of engineers, architects, attorneys and other professionals and court and arbitration costs) arising directly, indirectly or consequentially out of any action, legal or equitable, brought by any separate Contractor against OWNER, ENGINEER, or Consulting Engineer to the extent based on a claim arising out of CONTRACTOR'S performance of the Work. Should a separate Contractor cause damage to the work or property of CONTRACTOR or should the performance of work be any separate Contractor at the site give rise to any other claim, CONTRACTOR shall not institute any action, legal or equitable, against OWNER, ENGINEER or Consulting Engineer or permit any action, legal or equitable, against any of them to be maintained and continued in its name or for its benefit in any court or before any arbiter which seeks to impose liability on or to recover damages from OWNER, ENGINEER, or Consulting Engineer on account of any such damage or claim. If CONTRACTOR is delayed at any time in performing or furnishing Work by any act or neglect of a separate Contractor and OWNER and CONTRACTOR are unable to agree as to the extent of any adjustment in Contract Time attributable thereto, CONTRACTOR may make a claim for an extension of time in accordance with Article 12.

ARTICLE 11 - CHANGE OF CONTRACT PRICE SC-11.g Add the following language at the end of paragraph 11.9.2: Work described in the Contract Documents but not identified in the listing of unit price items shall be considered incidental to unit price work listed and the cost of incidental work included as a part of the unit price. SC-11.9.3. Paragraph 11.9.3. is hereby deleted in its entirety and the following, including new paragraph 11.9.3.1. through 11.9.3.4., is substituted in lieu thereof: 11.9.3.
