Excavation, in areas where 2 inch and larger roots occur, shall be done by hand. Roots 2 inches or larger in diameter, except directly in the path of pipe or conduit, shall be tunneled under and shall be heavily wrapped with burlap to prevent scarring or excessive drying. Where a mechanical trencher is operated close to trees having roots smaller than 2 inches in diameter, wall of trench adjacent to tree shall be hand trimmed, making clean cuts through roots.

If issued, they will be mailed or "FAXED" to all prospective Bidders no later than 3 calendar days prior to the bid date. Failure of any bidder to receive any such addendum or interpretation shall not relieve such Bidder from such obligation under his bid submitted. All addenda issued shall become part of the Contract Documents.

1.13 LIST OF MATERIAL FOR APPROVAL

A. The materials chosen for the design of the sprinkler system have been specifically referred to by manufacturer so as to enable the irrigation designer to establish the level of quality and performance required by the system design. When terms "or equal", "equal to", "or approved equal", "or accepted equivalent" and other similar terms are used, provide only the specific product or products specified, or approved by written Addendum. Approved substitutions may, because of different size, weight, configuration or other characteristics, require modifications to other elements of the work. If such substitutions are used, all such modifications to other elements of the work must be shown by shop drawings or other submittals as appropriate, and approved by the Irrigation designer. Any costs associated with such modifications will be at the Contractor's expense. For consideration of proposed equal equipment, the Contractor shall submit to Larry Rodgers Design Group not less than 7 calendar days prior to the bid opening a list of material under consideration.

B. Requests for review substitute items of material and equipment will not be accepted by Irrigation Designer from anyone other than Contractor. If Contractor wishes to furnish or use a substitute item of material or equipment, Contractor shall make written application to Irrigation Designer for acceptance thereof, certifying that the proposed substitute will perform adequately the functions called for by the general design, be similar and of equal substance to that specified, and be suited to the same use and capable of performing the same function as that specified. The Application shall state whether or not acceptance of the substitute for use in the Work will require a change in the Drawings or Specifications to adapt the design to the substitute and whether or not incorporation or use of the substitute in connection with the Work is subject to payment of any license fee or royalty. All variations of the proposed substitute from that specified shall be identified in the Application and available maintenance, repair and replacement service will be indicated. The Application shall also contain an itemized estimate of all costs that will result directly or indirectly from acceptance of such substitute, including costs of redesign and claims of other contractors affected by the resulting change; all of which shall be considered by Irrigation Designer in evaluating the proposed substitute. Irrigation Designer will be the sole judge of acceptability and no substitute will be ordered or installed without Irrigation Designer’s prior written acceptance. Owner may require Contractor to furnish at Contractor’s expense a special performance guarantee or other Surety with respect to any requests for review of substitute. The Irrigation Designer will record time required by Irrigation Designer and Irrigation Designer’s consultants in evaluating substitutions proposed by Contractor and in making changes in the Drawings or Specifications occasioned thereby. Whether or not Irrigation Designer accepts a proposed substitute, Contractor shall reimburse Irrigation Designer for the charges of review time and any of the Irrigation Designer’s consultants for evaluating any proposed substitute.

C. The Contractor shall submit (4) copies of a material list, complete with manufacturer's name and product numbers, (4) lists of comparable installations in operation under similar operating conditions, including customer address and location of installation. Any engineering drawings that would alter the system design of the proposed changes will be the responsibility and expense of the Contractor to provide.

Revised July 17. 2026 Page 15

D. Notification of the submitted data for consideration of "as-equal" to the equipment specified herein will be by Larry Rodgers Design Group three days prior to the bid opening. The “Or Equal” judgment has been addressed at the Federal 1st Circuit Court in the case of Whitten Corp. vs. Paddock Inc. April 12, 1974.

The case noted 4 major rulings regarding specifications: 1) the court ruled that “proprietary specifications are not a violation of anti-trust laws”. Further, the court stated that “trained professionals”, i.e. specifiers, “make informed judgments on products which they feel best serve the clients needs”. 2) The court ruled that other suppliers or manufacturers can qualify as “Or Equal” only when the specifier chooses to waive specifications or permit those suppliers or manufacturers to bid. It clearly states that the specifying source is charged with the responsibility and judgment for determining whether a proposed substitution is an “Or Equal”. 3) The specifier “may waive specifications in order to obtain a more desirable product for the client”. 4) “The burden is on the supplier or manufacturer who has not been specified to convince the specifier that their product is equal or better for the purpose of a particular project.”

E. The specific materials to be used will be as designated on the plan or in the bid schedule of Unit Prices. All materials to be incorporated in this will be new and of the best quality, meeting the requirements for such materials and for the purpose intended.

F. After the product has been approved, the contractor will use the same brand equipment consistently throughout the contract.

1.14 SUBMITTALS

A. (4) material lists of all products and materials to be used on the project shall be submitted to Larry Rodgers Design Group for review and approval. Then sent to the Owner's representative by Larry Rodgers Design Group for written approval prior to the installation of the irrigation system. The Owner's representative and Larry Rodgers Design Group reserve the right to reject any and all materials that have been installed but have not been approved. Four material list sets will be required, one of which will be returned approved or not approved to the Contractor for corrections.

B. The source for such products shall be submitted to Larry Rodgers Design Group, with detailed descriptions in the form of samples, shop drawings, specifications, tests or other means necessary to adequately describe the items submitted.

C. If it is found that the sources of supply have not furnished products meeting the intent of the contract documents/specifications, the Contractor shall thereafter replace from the approved source and shall remove completed work incorporating products, which do not meet contract requirements.

D. If rejected materials, equipment or work is not removed within (48) hours from the date of letter of notification, and the Owner shall have the right and authority to stop the Contractor and his work immediately, which will not extend the completion date. The Owner shall have the right to arrange for removal of said rejected materials, equipment or work at the cost and expense of the Contractor.

E. The failure of the Owner or Larry Rodgers Design Group to condemn improper materials and/or workmanship shall not be considered as a waiver of any defect which may be discovered later, or for work actually defective.

F. Coordinate the preparation and processing of submittals with the performance of the work so that work will not be delayed by submittals. No extension of time will be allowed because of failure to properly coordinate and sequence submittals.
