Sectional Monopole Tower Foundation & Installation Manual, Revision A
PRIOR TO INSTALLATION
Introduction
This manual provides information for the construction of a foundation suitable for installing Southwest Windpower’s Skystream 3.7 on one of the following
Southwest Windpower towers:
• 33.5 ft (10.2 m) Monopole Sectional Tower, part number 3-CMBP-3218
• 45 ft (13.7 m) Monopole Sectional Tower, part number 3-CMBP-3219
Information for four different “styles” of foundation is provided. The choice of foundation will depend on local building conditions, available construction
equipment, and local regulations. The four styles of foundation include:
• Pier Foundation – A “column” shaped foundation; diameter and depth vary depending on soil conditions and maximum wind speed.
• Mat Foundation [33.5 ft (10.2 m) tower only] – A “square” shaped foundation; length, width and depth vary depending on soil conditions and maximum wind
speed.
• Pad and Pier Foundation [45 ft (13.7 m) tower only] – An alternative to the Pier foundation – may be easier to construct than Pier foundation if an auger is
not available.
• SMarT Foundation™ - manufactured by AnemEronics Inc. , this foundation utilizes a “kit” that is specially designed to construct a foundation for
Southwest Windpower’s Monopole Towers.
For the Pier and Mat foundations, the information in the manual is sufficient for individuals knowledgeable in working with concrete to construct the founda-
tions. The manual provides useful tips about critical areas of construction, however it does not provide “step by step” instructions for these
foundations. It assumes constructor is has the knowledge and experience to complete the foundation.
Detailed instructions are provided for the SMarT Foundation in Appendix C. The SMarT Foundation kit was designed specifically for Southwest Windpower’s
Monopole towers and may be utilized by both experienced and amateur installers. The unique design of the SMarT foundation provides material and construc-
tion time savings compared to a conventional foundation.
Directions for raising, leveling, and lowering the tower are provided in this manual, refer to the Skystream Owner’s Manual for instructions for installing
Skystream on the tower.
IMPORTANT NOTE:
The foundation drawings contained in the Appendices of this manual present foundations designed in accordance with the 2006
INTERNATIONAL bUILDING CODE (IbC 2006) and ASCE 7-05 MINIMUM DESIGN LOADS FOR bUILDINGS AND OTHER STRUCTURES. These
drawings may therefore not be appropriate in localities with construction requirements that differ from these standards.
