C. RESTRICTIONS ON PROCESS, PIPING, AND EQUIPMENT OUTAGES

1. General:

Modifications to existing structures and connections between new work and existing facilities require certain processes, piping and equipment to be removed from service and will result in disruptions to plant operations. This section sets forth restrictions on the removal of the Rock Creek Wastewater Treatment Facility or any portion thereof from service. These restrictions must be adhered to and shall be taken into account during the preparation of the Construction Schedule as required in Section 01300.

01100 - 3 May 2011 Rock Creek Wastewater Treatment Facility Aeration Basin and Aerobic Digester Diffuser Replacement If the Contractor believes that longer disruptions than those set forth in this section will be required to accomplish the Work, it shall be the Contractor’s responsibility to provide additional temporary plant, piping, equipment and personnel necessary to comply with the requirements of this section.

Provide product and materials information for review by the Engineer to demonstrate that the materials and equipment to be furnished and the methods of work comply with the provisions and intent of the contract documents. Furnish manufacturers' fabrication drawings, specifications, descriptive data, certificates, samples, test methods and results, schedules, and manufacturer's installation and other instructions, operation and maintenance manuals, repair/replacement parts, maintenance supplies, requests for substitutions, and miscellaneous items specifically required in the contract documents

1.2 QUALITY ASSURANCE

A. ACCURACY AND COMPLETENESS

The Contractor shall be responsible for the accuracy and completeness of the information contained in each submittal and shall assure that the material, equipment or method of work shall be as described in the submittal. The Contractor shall verify that all features of all products conform to the specified requirements. Submittal documents shall be clearly edited to indicate only those items, models, or series of equipment, which are being submitted for review. All extraneous materials shall be crossed out or otherwise obliterated.

B. COORDINATION

Coordinate submittals with the work so that work will not be delayed. Coordinate and schedule different categories of submittals, so that one will not be delayed for lack of coordination with another. No extension of time will be allowed because of failure to properly schedule submittals.

C. CONFORMANCE WITH SPECIFIED REQUIREMENTS

Submittals are specified for those features and characteristics of materials, equipment, and methods of operation that can be selected based on the Contractor's judgment of their conformance to the specified requirements. Other features and characteristics are specified in a manner that enables the Contractor to determine acceptable options without submittals. The review procedure is based on the Contractor's guarantee that all features and characteristics not requiring submittals conform as specified. Review shall not extend to means, methods, techniques, sequences or procedures of construction, or to verifying quantities, dimensions, weights or gages, or fabrication processes (except where specifically indicated or required by the Contract Documents) or to safety

01300 - 1 May 2011 Rock Creek Wastewater Treatment Facility Aeration Basin and Aerobic Digester Diffuser Replacement precautions or programs incident thereto. Review of a separate item, as such, will not indicate approval of the assembly in which the item functions.

D. SUBSTITUTION REQUEST

Whenever an item of material or equipment is specified or described in the Contract Documents by using the name of a propriety item or the name of a particular Supplier, the specification or description is intended to establish the type, function, appearance, and quality required. Unless the specification or description contains or is followed by the words reading that no like, equivalent, or “or equal”, no substitution or “or equal” is permitted.

It is the Engineer’s sole discretion that a substitution or an “or equal” material or equipment is functionally similar, comparable quality, and equal performance to that specified. Contractor is responsible for any additional costs related to “or equal” items such as, but not limited to, construction methods, engineering design changes, electrical service changes, or equipment pad sizing. Submittal review of substitution or “or equal” items are at the Contractor’s expense. Cost to review a substitution or “or equal” item is 750 U.S. dollars per item.

E. EFFECT OF SUBMITTAL REVIEW

Review of drawings, methods of work, or information regarding materials or equipment proposed by the Contractor shall not relieve the Contractor of responsibility for errors therein. In reviewing submittals to confirm compliance with the provisions and intent of the contract documents, Engineer and Owner, and any officer or employee thereof, assume no risks or liability for construction. The Contractor shall have no claim under the contract on account of the failure, or partial failure, of the method of work, material, or equipment so reviewed.
