| Tashjian Tower is pleased to
submit this introduction letter that details some of our services. We
have over eighteen years of experience in the tower industry. We had
prepared analysis, documentations and drawing packages for Crank-Up
Towers, Self Supporting Towers, Guyed Towers and Monopoles. The
combination of high qualification and low overhead allows Tashjian Tower
to offer you and your client unparalleled services, we have the ability
to effectively addresses a wide range of structural, defined their
nature and significant and develop cost-effective solution.
Tashjian Tower is a firm with an extra ordinary determination to
provide superior customer services; we specialize in tower Engineering,
Inspection, Mapping, Documentation, Analysis, Co-Location, Foundation
Design and Geotechnical services. For your review, we have enclosed a
partial list of our services along with associated costs.
Tower Certifications
It is assumed 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 six each tower elevations drawings, four sets of
tower calculations for the complete tower including the foundation, and
three 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 prepared; modification drawings are created,
and an estimate of the steel require to modify the tower. The above
documentation will be sealed if the tower site is within the one of the
states that we are licensed. Our engineers are licensed in Ca., Oregon,
Arizona, Nevada, Virginia, Pennsylvania, Georgia, Massachusetts,
Louisiana, and Idaho. Reports are completed within 5 to 10 working days
depending on backlog.

Tower Inspection, Tower Mapping, and Tower Documentation
$800 per site
The scope of work for inspection, mapping, and documentation includes
the measuring of member sizes, documenting the antenna sizes, antenna
elevation, antenna line sizes and location on tower, guy geometry,
visual inspection of the tower, photos of the tower, and 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 (Pad, Pier, Drill and Bell, Pad
and Pier)$500 per Tower
Soils report is to be provided by owner or the foundation design will
be based on normal soil. The scope of work includes providing 6 sets of
calculations and drawings for the tower foundations including optimizing
the size for 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) $2,500
The scope of work includes providing six sets of tower foundation
plans for custom tower foundation where rock, water, or other soil
conditions other than normal soil conditions exists.
Tower Design $50/ per hr
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 crosses and stealth panel walls, 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 experience in weld
design, galvanized structures, and their effect on warping structures.
The design work is done using Cadkey or Solidworks cad software.
Autocad formats can be provided on completion. Full size prints are
available on request while 11 x 17 is the normal format.
Tower Site Plans: $2,500 per plus all expenses
The scope of work includes taking survey information, customer
supplied data, zoning information and creating a site plan showing all
existing and proposed structures. An elevation drawing of the tower is
shown on the site plan. Typically these plans are used in the zoning
process.
Site Surveys at Grade: $2,000
The scope of work includes staking the property lines, surveying the
grade, and providing a topography map.
Drainage and Grading Plan: $2,000
The scope of work includes providing a grading and drainage plan for
typical communication sites.
Electrical Plans: $1,000
Includes electrical plans for typical communication site with 200-amp
service, generator, transfer switch, building, and light.
Soils Engineering
Customers scope of work for Geotechnical
Services.
$2,600/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
