It is assumed that the owner provides all available information. The scope of this work consists of a feasibility study for the installation of customer specific equipment on existing towers. The scope of work includes providing four sets of tower elevations drawings, four sets of tower calculations for the complete tower including the foundation, and four copies of the tower report summarizing the tower findings and recommendations.
The report includes tower overstresses if found but does not include the details of the modification to correct these overstresses. Once the owner decides to proceed with the modification, structural calculations are prepare, modification drawings are created, and an estimate of the steel require to modify the tower is produced. The above documentation will be sealed if the tower site is within the one of the states our engineers are licensed: California, Oregon, Arizona, Nevada, Washington, Utah, Texas, Idaho, New Mexico, and Alaska.
| Up to 100′ | Poles, Self-Support and Guyed Towers | $2,625 | ||
| 100′ -200′ | Poles, Self-Support and Guyed Towers | $3,360 | ||
| 200′ -300′ | Self-Support and Guy Towers | $3,990 and up |

Tower Inspection, Tower Mapping and Tower Condition Assessment Report:
- The scope of work for inspection, mapping, and documentation includes the following:
• Measuring of member sizes
• Documenting the antenna sizes
• Antenna elevation
• Antenna line sizes & location on tower
• Guy geometry
• Visual inspection of the tower w/ photos of the tower & field report
- The client receives a copy of the field inspection notes and photos if requested. The scope includes conducting field investigation and collecting engineering data.
Tower Foundation Plans (Standard Plans)
Standard Plans- Soils report is to be provided by owner or the foundation design will be based on normal soil. The scope of work includes the following:
• Providing four sets of calculations
• Drawings for the tower foundations (Including optimizations for the size of the tower)
• Reinforcement bars location, size, and weight
• Anchor bolt locations, in conformance with a customer provided soils report
- These standard foundation plans are for standard tower foundations types such as pads, drill and bell foundations, pad to Pier, and straight piers.
Custom Tower Foundation Design
Rock Anchor, Water, Etc.- The scope of work includes the following:
- • Providing four sets of tower foundation plans for custom tower foundation where rock, water, or other soil conditions other than normal soil conditions exists
Tower Design
- The design team has many years of experience in designing and modifying towers. The typical design cyclical includes layout, design review, fabrication details, submittal of sealed drawing package, and construction drawing package. The design team has completed a wide range of towers including custom crank up towers, self-supporting towers to 400, guy tower to 2000, tower trailer units, roof top mounts, stealth designs including water tanks, pine and palm trees, and windmill towers, custom equipment platforms, and custom antenna mounts.
- As a tower manufacturer, our design team is aware of the requirements of owners, fabricators, and contractors. Our drawing package are used for obtaining building permits, construction bid walks, construction documents, owners records, fabricator details including weld design, and managers who want their projects on time. We are experienced in weld design, galvanized structures, and their effect on warping structures.
- The design work is done using Cadkey or Solidworks cad software. Autocad formats and electronic files can be provided on completion. Full size prints are available on request while 11 x 17 is the normal format.
Tower Site Plans
Expenses Not Included- The scope of work includes the following:
• Taking survey information
• Customer supplied data
• Zoning information
• Creating a site plan showing all existing & proposed structures.
- An elevation drawing of the tower is shown on the site plan. Typically these plans are used in the zoning process.

$7,875/Each
This includes all items described in the typical geotechnical specifications. For your information, the price includes two borings, one direct shear test, one consolidation test, five each moisture samples, one chemical analysis, resistivity testing and sieve analysis. The resistivity test adds approximately $1,500 to the cost above. Four copies of the report will be provided.
Please note the above work does not include rock conditions, four-wheel access, or other abnormal soil conditions. Normal access is assumed in the above pricing.
Other engineering services available are lease exhibits, tower expert at zoning hearings, public works counter service in central California, minor electrical plans, communication building design, communication equipment slab design, review of manufactures drawings and sealing of plans, and tower specification writing. Fees may vary depending on complexities.
