The concrete blocks shall have alignment keys in the vertical faces that resist movement between the blocks upon post-tensioning.

Each block will have integral conduits perpendicular to each vertical face to accommodate the post-tensioning rods.

Each block shall not exceed 15,000 lbs.

The concrete shall have a minimum compressive strength of 5,000 psi @ 28 days matching the strength used in the engineering calculations.

The top surface of each block shall be fully level with the top surface of each of the adjacent blocks, once the blocks are post-tensioned. A cumulative variance not to exceed ½” across the entire foundation in any direction will be acceptable. Variance from block to block shall not exceed ¼”.

The design of the post-tensioning cables or threaded rods shall bind together the requisite number of blocks in a manner that can resist the tower loads. The block and post-tensioning design shall ensure that there will be no movement between blocks once they are post-tensioned. The contractor shall provide post-tensioning values and calculations for each site.

Stacking of blocks is acceptable as long as the design is approved and wet stamped by a qualified

Professional Engineer (P.E.) in the state of the installation site.

The design shall allow for increase in load capacity by adding additional blocks without disrupting the integrity of the existing foundation.

The spacing of the post-tensioning cables or rods shall accommodate the placement of three (3) sets of cast anchor bolts (one for each tower leg) spaced 21’ apart. The bolt center for each leg shall be 18”. See paragraph “s” for alternate tower mounting possibilities.

The foundation drawings and calculations shall be prepared in accordance with the specific state of installation standards. All drawings shall be certified wet stamped by a licensed P.E. in the state of the installation site.

The design and engineering analysis of the precast block foundation shall be in accordance with the American Concrete Institute’s ACI 318-08: Building Code Requirements for Structural

Concrete (and Commentary).

All post-tensioning cables or rods must be coated in a manner that will preclude corrosion due to prolonged exposure to the elements.

The conduits in the blocks are not required to be filled, following post-tensioning.

The exposed hardware used with the blocks shall be hot dip galvanized (HDG).

Each block shall have a minimum of three (3) lifting points that shall not protrude beyond the outer surface of the block. The top surface shall allow for drilling to a depth of 5”, which will allow for equipment anchoring at additional locations.

The block configurations shall be designed to the listed reactions and provided soil reports. The blocks shall be designed to accommodate 3-legged towers with 21′ face widths. Additionally, the bolt pattern for each leg shall consist of six (6) 2″ diameter bolts equally spaced in a bolt circle of

18″ diameter, centered on the 21′ face corners. The orientation of the bolts shall be aligned such that all bolts on opposite sides of the bolt circle are parallel with the faces of the tower.

Alternate tower mounting interface solutions (e.g. mounting plates that can be drilled in the field for precise alignment with the tower bolt pattern) can be proposed. Upon government approval, proposed mounting interface solutions may be utilized in lieu of precast bolts.
