About this file
This is a specification section (Section 10 75 16) for ground-set flagpoles required for the Montezuma National Wildlife Refuge & New York Ecological Services New Multipurpose Facility project (Beardsley No. 23052).
The specification requires cone-tapered aluminum flagpoles fabricated from seamless extruded tubing complying with ASTM B 241/B 241M, Alloy 6063, with a minimum wall thickness of 3/16 inch and an exposed height of 30 feet. Acceptable manufacturers include American Flagpole (a Kearney National Inc. Company), Concord Industries Inc., Ewing Flagpoles, or an approved equal. Flagpoles must be obtained as complete units from a single manufacturer and include all fittings, accessories, bases, and anchorage devices. The flagpoles must withstand wind loads determined according to NAAMM FP 1001 with a basic wind speed of 90 mph. Flagpoles should be constructed in one piece if possible; if multiple pieces are necessary, they must use flush hairline joints with self-aligning internal sleeves without fasteners or screw collars. The specification includes requirements for a metal foundation tube with corrugated steel construction, fiberglass or PVC pipe foundation sleeves, finial balls with gold anodic finish, and an internal halyard winch system with manually operated controls and stainless-steel cable. Installation requirements specify preparation of foundations through cast-in-place concrete work, placement of the flagpole in the foundation tube with steel centering wedges, compaction with sand, and sealing with elastomeric joint sealant and flashing collar. Submittals must include product data, shop drawings with construction details and foundation system plans, and operation and maintenance documentation. Flagpoles must be spiral-wrapped with heavy paper and enclosed in protective containers for delivery.

PART 3 - EXECUTION
3.1 PREPARATION
A. Prepare uncoated metal flagpoles that are set in foundation tubes by painting below-grade portions with a heavy coat of bituminous paint.
B. Foundation Excavation: Excavate to neat clean lines in undisturbed soil. Remove loose soil and foreign matter from excavation and moisten earth before placing concrete. Place and compact drainage material at excavation bottom.
C. Provide forms where required due to unstable soil conditions and for perimeter of flagpole base at grade. Secure and brace forms to prevent displacement during concreting.
D. Foundation Tube: Place foundation tube, center, and brace to prevent displacement during concreting. Place concrete. Plumb and level foundation tube and allow concrete to cure.
E. Sleeves: Locate and secure sleeves in forms by bracing to reinforcement and forms.
F. Anchor Bolts: Locate and secure anchor bolts in forms with templates and by tying to reinforcement.
G. Place concrete, as specified in Section 03 30 00 "Cast-in-Place Concrete." Compact concrete in place by using vibrators. Moist-cure exposed concrete for no fewer than seven days or use nonstaining curing compound.
H. Trowel exposed concrete surfaces to a smooth, dense finish, free of trowel marks, and uniform in texture and appearance. Provide positive slope for water runoff to perimeter of concrete base.
3.2 FLAGPOLE INSTALLATION
A. General: Install flagpoles where indicated and according to Shop Drawings and manufacturer's written instructions.
