17、desired, and budgetary constraints. The area factors will be determined by a registered landscape professional. Reference is made to UFC 3-210-05FA. While the design of a system with pop-up heads may be justified in some geographic areas, bubbler type systems may be required in areas where water con

The amount of water required is determined from the type of turf to be irrigated, climate, terrain, and soil conditions. System piping layout, pipe sizes, and selectio

20、n and spacing of heads and emitters must provide the required amount of water and complete coverage of the irrigated areas. Provide valves to allow irrigation of each area separately.*1.1 REFERENCES*NOTE: This paragraph is used to list the publications cited in the text of the guide specification. T

Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the subm

44、ittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the subm

45、ittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office.
