About this file
This is a set of construction design plans and specifications for the Colorado River Irrigation Project (CRIP) Lateral 73-36 Check 1 Replacement project located in La Paz County, Arizona. The project, prepared by DOWL engineering firm and issued for construction in March 2025, involves replacing an existing water control check structure on the irrigation lateral system serving Native American trust lands managed by the Bureau of Indian Affairs Office of Trust Services Division of Water and Power.
The project scope includes construction of a new check structure with cast-in-place concrete base slab, weir wall, headwall, and cross walls; installation of two 36-inch cast iron canal gates and one 60-inch stainless steel slide gate; temporary bypass construction with sheet pile checks and embankments to maintain water flow during construction; and a precast concrete headgate structure for Sublateral 73-36-7. Key design elements specified include concrete with f'c = 4,000 PSI minimum, Grade 60 reinforcing steel, hot-dip galvanized structural steel components, steel bar grating walkways with pipe railings, and wood weir top boards anchored to concrete ledges. The design incorporates construction and contraction joints with hydrophilic waterstops, pressure relief holes in the base slab, and provisions for future equipment installations. Site preparation involves excavation, compacted structural fill placement, and riprap erosion protection. The construction drawings include detailed plans, sections, elevation views, reinforcement schedules, material specifications, and inspection requirements compliant with ACI 318, AISC 360, and ASCE 7 design standards.

1. 'AS' = ADDITIONAL BARS EQUAL IN TOTAL NUMBER TO REGULAR
REINFORCEMENT CUT BY THE OPENING. PLACE ONE-HALF TOTAL BARS TO
EACH SIDE OF OPENING & IN THE SAME TRANSVERSE POSITION AS THE
REGULAR REINFORCEMENT.
2. 'AS' BAR SIZE TO BE SAME AS REGULAR REINFORCEMENT IN EACH DIRECTION.
3. THIS DETAIL APPLIES UNLESS ADDITIONAL REINFORCEMENT SPECIFICALLY
INDICATED AT OPENINGS ON DRAWINGS.
4. ADDITIONAL BARS IN SINGLE OR DOUBLE LAYER/CURTAIN MATCHING REGULAR.
5. ADDITIONAL HORIZONTAL AND VERTICAL BARS ARE NOT NECESSARY FOR
OPENINGS UP TO 9 INCHES. USE ONLY THE DIAGONAL BARS. FOR OPENINGS
SMALLER THAN 9 INCHES DO NOT CUT BARS, POSITION NORMAL REINFORCING
AROUND OPENING.

PRECAST HEADGATE STRUCTURE (INLET)
1 1 2 scale feet
0 76543
3/8" = 1' - 0"
ISOMETRIC NOTES:
I1. ISOMETRIC VIEWS OF THE STRUCTURE ARE INTENDED TO
PROVIDE AN OVERALL GRAPHIC OF ARRANGEMENT AND
KEY ELEMENTS - SOME FEATURES DETAILED IN THE
PROJECT PLANS AND SPECIFICATIONS ARE NOT SHOWN
HERE.
I2. GROUND SURFACES ARE NOT SHOWN. CANAL INVERT IS
TOP OF BASE SLAB, CANAL BANK NEAR WALL TOP.
PLAN NOTES:
1. SEE SHEET S01 FOR GENERAL STRUCTURAL NOTES.
2. SEE SHEET S02 FOR STRUCTURAL MATERIALS AND INSPECTION SCHEDULES.
3. SEE CIVIL SHEETS FOR STRUCTURE LOCATION ON PROJECT SITE, EARTH WORK DETAILS, AND RIPRAP.
4. HEADGATE INLET AND OUTLET STRUCTURES ARE INTENDED TO BE PLANT PRECAST CONCRETE ELEMENTS.
5. HEADGATE HEADWALL AND FOOTING TO BE SHIPPED ONE PIECE. WINGWALL AND FOOTING SEGMENTS TO BE SHIPPED ONE PIECE - TWO IDENTICAL SEGMENTS MIRRORED ABOUT FLOW CENTERLINE. OUTLET WALL AND FOOTING TO BE SHIPPED ONE PIECE.
6. CONSTRUCTION JOINTS AT HEADGATE HEADWALL / WINGWALL SEGMENT CONNECTION SHALL INCLUDE INTERNAL REINFORCEMENT/CONNECTIONS AND BE FIELD GROUTED TO A FLUSH CONDITION - EXPOSED STEEL CONNECTION HARDWARE IS
PROHIBITED.
7. WALL THICKNESS, FOOTING THICKNESS AND WIDTH, BASED ON DESIGN CRITERIA AND MATERIALS OUTLINED IN STRUCTURAL GENERAL NOTES ON SHEET S01, ARE SHOWN FOR BID BASIS. THE PRECAST SUPPLIER MAY REDUCE MEMBER THICKNESS AND PROPOSE ALTERNATE REINFORCEMENT DETAILS PROVIDED THE SECTIONAL STRENGTH AND STABILITY SHOWN IN THE BID BASIS IS PROVIDED AND DOCUMENTED BY CALCULATIONS ORIGINATED BY THE PRECAST SUPPLIER. REINFORCEMENT CONTENT CALCULATIONS MUST INCLUDE A
20% INCREASE FOR ENVIRONMENTAL DURABILITY.
8. THE PRECAST SUPPLIER IS RESPONSIBLE FOR THE DESIGN AND INSTALLATION OF LIFTING HARDWARE, CONSIDERATION OF SHIPPING RELATED LOADS/STRESSES ON PRECAST SEGMENTS, AND PRECAST INSTALLATION INSTRUCTIONS.
9. PRECAST CONCRETE COVER TO BE 1 1/2" REGARDLESS OF REINFORCEMENT SIZE.
