PART 1 - GENERAL

1.01 OBJECTIVE

A. The objective of these specifications is to provide for the installation of a Rainbird or Toro irrigation system (or pre-approved equal system), which shall effectively irrigate all areas to be covered and shall be installed in a professional, workmanlike manner. The specifications, design details, and irrigation drawings are to be considered part of the

Contract and the Contractor shall follow the specifications precisely. The plans and specifications are intended to include everything requisite and necessary for the proper installation of the work whether each necessary item is mentioned herein or not. All labor, overhead, materials and profit for any and all tasks associated with the installation of this project shall be included in the bid price.

B. The plans and specifications are intended to be cooperative and any item called for in one and not the other shall be as binding as if called for in both. If a discrepancy exists between an item called for in the plan and the specifications, contact the irrigation designer and the Park Representative by email asking for a determination.

C. All work specified herein or called for on the drawings shall be executed in accordance with all governing ordinances, laws and regulations that meet all local conditions. If the Contractor performs any work contrary to such codes, laws or regulations, they shall assume full responsibility and bear all costs necessary to correct the work, without additional cost to the Park.
