ProTeX was retained by ADW Communication Services, Inc. Services, Inc. to evaluate the surface and subsurface soil conditions. The content of this report contains the findings from the field exploration and laboratory testing, with supporting foundation and site preparation recommendations, for the proposed support structure and communications tower construction.
1.2 Proposed Site Development
This firm understands the proposed development will consist of:
• Self Support Communications Tower
• Support/equipment structure
The proposed structures are anticipated to have relatively light to moderate loads. Additional recommendations for spread foundations, drilled shafts, rock anchors and spread footings can be provided upon request.
1.3 Terms and Conditions
This report was prepared for ADW Communication Services, Inc. Services, Inc.. The contents of this report may not be relied upon by any other party without the expressed written permission of
ProTeX - the PT Xperts, LLC and the written permission of ADW Communication Services, Inc.
Services, Inc.. The report presents site conditions at the time of the investigation and for the aforementioned proposed development. The report should be updated prior to construction if a maximum of one year has elapsed from the issued date.
2.0 FIELD AND LABORATORY TESTING
2.1 Geotechnical Site Reconnaissance
The Landsend Tower Site is located near Grand Junction, in Mesa County, Colorado, at the coordinates of 39.090635°, -108.223753°. At the time of the field investigation on July 15, 2021 the following site conditions were observed:
• Rough graded mountain top yard area to the near an existing tower
• Light cover of vegetation consisting of highland grasses near the proposed construction area
• Surface cobbles and boulders were located in and around the proposed construction area
• The proposed tower site was relatively flat
2.2 Field Testing - Seismic Refraction Survey
A seismic refraction survey consists of introducing a pulse into the ground and recording the time of first arrival vibrations at different horizontal distances. The pulse was generated by manually striking a steel plate with a sledge hammer. The pulse is recorded on an engineering seismograph utilizing one or more sound vibration detection devices known as geophones. The waves recorded are called
P-wave’s.
The seismic refraction survey conducted at this site was performed along various seismic line trajectories in order to collect representative seismic data. The seismic refraction lines were conducted in the area of the proposed structures at overall lengths of 62.5 feet. Refer to Appendix B for seismic line locations and Appendix C for subsurface stratum analysis.
2.3 Laboratory Testing
Soil Subsequent to the field investigation, soil samples were submitted for laboratory testing. Tests were performed to determine the following:
• Sieve Analysis and Atterberg Limits- Used for formal classification of soils in general accordance with the Unified Soil Classification System (USCS) per ASTM Test Method
D2487. Sieve analysis is performed in general accordance with ASTM Test Methods D421, D422 and D-1140. The Atterberg Limits were determined in general accordance with
ASTM Test Method D-4318.
Laboratory Test Summary
3.0 GENERAL SITE CONDITIONS
3.1 Soil/Bedrock Stratigraphy
The seismic refraction survey is interpreted to indicate a subsurface profile consisting of two subsurface strata (Refer to Appendix C of this report for seismic field survey):
1. Layer 1 - This uppermost surficial layer has an approximate velocity range of 1500 to
2500 fps. The layer thickness and depth from existing site surface grade varies from the surface to approximately 1 to 6 feet from the existing ground elevation, and likely represents a layer of clayey sand with various amounts of gravel and cobbles.
2. Layer 2 – This is considered the transitional zone, between Layer 1 and Layer 3, where the surficial soil layer transitions from dense soil with high amounts of gravel and cobbles to very highly weathered/fractured. The approximate velocity range of this transition zone is 2500 to 3500 fps. The layer thickness is approximately 1 to 2 feet. This layer begins approximately 1 to 6 feet below existing surface and likely represents a layer consisting mainly of dense soils with high amounts of gravel and cobbles to very highly weathered/fractured rock.
3. Layer 3 - Interfaces with the base of Layer 2 and has an approximate velocity range of between 3500 fps to 5500 fps. This layer extends from approximately 2 to 8 feet below existing surface to the extent of the explored depth and likely represents a zone of highly to moderately weathered/fractured rock.

Layer 3 140 4000 1.25-2.00 0.228 4.40 40 Poor to Fair
ABC = Allowable (Design) Bearing Capacity
3.2 Excavation and Workability
Based on the seismic refraction survey, it is anticipated that conventional excavation equipment may be utilized for Layer 1, the clayey sand with various amounts of gravel and cobbles. Layer 2 is the transitional zone consisting mainly of very highly weathered/fractured rock will likely require heavier excavation equipment and may require hoe ram attachment to accomplish effective removal.
Layer 3 consists of highly to moderately weathered/fractured rock and will likely require heavier excavation equipment with hoe ram attachment, coring and/or possible blasting techniques to accomplish effective removal.
It should be noted that this is generalized assessment is not intended to be the sole basis for contractors preparing earthwork bids. Undiscovered/unexpected subsurface conditions may make excavation more difficult than expected. In addition, the relative ease/efficiency of excavation is heavily dependent on operator skill and the type of equipment assigned to the project. Thus, prospective earthwork contractors bidding on this project need to assess site excavation conditions for themselves.
Trench shoring, benching, or laying back of excavations greater than 3 feet in depth may be required to satisfy government safety regulations for personnel safety.
3.3 Potential for Soil Expansion (Swell Potential)
Based on laboratory testing the surface soils are comprised mainly of low-medium plasticity clayey sand with various amounts of gravel and cobbles; thus, the expansion potential of the native soils is anticipated to be low at the surface.
3.4 Seismic Characteristics
The subject site is located in an area of seismic activity. Values have been developed based on knowledge of the local geological conditions, soils/ weathered rock encountered during the site investigation of the subsurface soils, and the 2018 International Building Code (IBC). The 2018 IBC references the American Society of Civil Engineers (ASCE) 7-16 standard. Based on knowledge of the geology of the area a 100 feet boring was not advanced, however, based on seismic survey analysis weathered rock is anticipated to a depth of 100 feet.
4.0 RECOMMENDATIONS
The recommendations contained herein are based on the findings of the site visit and field investigation and engineering experience.
4.1 Foundations
It is highly recommended that the design of foundations be done under the direction of a registered professional engineer with structural expertise. It is recommended that foundation excavations be inspected prior to placement of concrete to ensure they are free of debris and loose soils.
4.2 Spread Foundations
Conventional spread footings can be considered for tower and support structures. Due to the properties of the native soils as indicated by field classification and seismic refraction survey, it is recommended that foundations bear on a firm subsurface stratum of weathered rock with a minimum frost depth of 54 inches minimum.
Site Class C (very dense soil and soft rock)
Central Latitude 39.090635°
Central Longitude -108.223753°
Ss Spectral Acceleration for Short Period 0.269g
S1 Spectral Acceleration for a 1-Second period 0.068g
Fa Site Coefficient for Short Period 1.3
Fv Site Coefficient for a 1-second Period 1.5
Resistance to uplift loads may require that spread footings for this project be supported at depths significantly greater than 54 inches. A minimum footing width of 2 feet is recommended for this site.
Allowable bearing pressures for the recommended support conditions would be as indicated below into rock stratum 54 inches below finish grade:

Very Highly to Highly Weathered and Fractured Rock (Layer 2)
2500 psf
1.0 Highly to Moderately Weathered and Fractured Rock
(Layer 3) 3500 psf
Tower footing uplift resistance can be provided by the weight of soil lying above the footing block. The soil can be assumed to be a wedge-shaped solid have a moist unit weight of 130 pcf acting within a zone bounded by a plane inclined at 20º to the vertical rising up from the top of the footing to the ground surface. A minimum factor of safety of 1.5 is recommended to be applied against transient uplift loads. Sliding resistance to lateral loads can be provided by passive pressure and frictional resistance at the footing/soil interface. Passive resistance can be developed by utilizing an equivalent fluid pressure. Frictional resistance can be considered an interface friction factor. See lateral earth pressures section for equivalent fluid pressure and interface friction factor.
Preparation of the site to raise or lower the building pad should be done in accordance to the
Section 5 - Site Preparation.
4.3 Lateral Earth Pressures
The following design parameters are presented for lateral stability analysis:
Foundation Toe Pressures: 1.33 X Max. Allowable
*Lateral Backfill Pressures:
Unrestrained Walls 33 psf/ft
Restrained Walls 51 psf/ft
Lateral Passive Pressures:
Layer 1 462 psf/ft
Layer 2 546 psf/ft
Layer 3 616 psf/ft
Coefficient of Base Friction:
Independent of Passive Resistance
Layer 1 0.35
Layer 2 0.50
Layer 3 0.75
*The backfill pressures stated do not include temporary forces imposed during compaction of the backfill, swelling pressures developed by over-compacted clayey backfill soils, hydrostatic pressures from inundation of backfills, and/or surcharge loads. Walls should be suitably braced during backfilling to prevent damage and deflection.
Design of below grade structures should account for or prevent potential hydrostatic buildup. In addition, any below grade structure penetrations to facilitate drainage may allow piping of soil and water if not addressed properly in the design of the structure.
4.4 Drainage
Establishment and long-term maintenance of proper lot post-construction surface drainage is also critical. It is recommended that structural foundation/floor slab bearing soils not be exposed to moisture infiltration/fluctuations. Roof runoff should be collected and discharged away from the structures. Drainage of surface water away from the structures should be provided during construction and maintained by the owner throughout the life of the structure. In no case should long-term ponding be allowed near structures.
4.5 Slope Stability
Stability of cut and fill slopes are dependent on soil properties such as density, cohesion, moisture content, etc. Site specific laboratory testing and experience indicates that these properties can vary significantly across the site. Temporary slopes for installation of underground utilities or structures should follow OSHA guidelines.
The following minimum excavation/cut slopes were determined by the subsurface stratums analyzed from the seismic refraction survey lines:
Subsurface Stratum Depth
(ft)
Temporary Cut Slope
(H:V)
Layer 1 0-6 2:1
Layer 2 – Transitional Layer 6-8 1:1
Layer 3 >8 1:2
-Observation should be performed by a ProTeX engineering representative, due to variation of subsurface stratums, during excavations to determine final layer depths and allowable slopes
5.0 SITE PREPARATION
The following recommendations are presented for site grading. It is recommended that a ProTeX geotechnical engineer’s representative observe and test the earthwork and foundation portions of this project to ensure compliance with this Soil Investigation report.
Prior to placement of fill a representative of ProTeX should observe the clearing process. Clearing will include removal of site vegetation and any mature vegetative root systems. The areas cleared should be inspected prior to and during scarification for evidence of organic material or loose areas that may require additional removal or processing.
After clearing, the exposed soils (layer 1) in building areas and where fills are to be placed, should be scarified a minimum of 8 inches, moisture conditioned and compacted as specified below. The surface should be free from ruts, or other uneven features that would tend to prevent uniform compaction by the equipment used. If layer 2 or layer 3 is encountered a representative of
ProTeX should be contacted to observe and confirm rock layer stratums prior to concrete placement.
Excavations into rock should be inspected to be clear all debris.
Sloping areas steeper than 5:1 (horizontal: vertical) should be benched to reduce the potential for slippage between slopes and fills. Benches should be level and wide enough to accommodate compaction and earth moving equipment.
Fill material should be free of organics, vegetative matter, deleterious or foreign material, rocks, and lumps having a nominal diameter of 6 inches. Native soils may be used as fill material provided; they are compacted as specified. If needed, imported fill material should be approved low expansive potential soils.
Fill material should be placed in layers, that when compacted, do not exceed 6 inches. Each layer should then be placed evenly and thoroughly mix during spreading to ensure uniformity of moisture throughout each layer. Each fill layer should be compacted to specified density and moisture content.
Compaction equipment should be able to compact the fill to the specified density. Compaction of each layer should be continuous over its entire area and the compaction equipment should make sufficient passes to ensure that density has been obtained.
Soil compaction is recommended to the following densities and moisture contents as determined in accordance with ASTM D-698, AASHTO T-99 or applicable equivalent:
Compaction Specifications for Conventional Foundations
For Native and Approved Import Soils
Material Compaction Percent Moisture
Below Foundation Level and Flat Work 95% Min Optimum to +4 of Optimum
Fills at Depths 5 to 10 Feet Below Finish Grade 98% Min -2 to +2 of Optimum
Fills at Depths 10 Feet or Greater Below Finish Grade 100% Min -2 to +2 of Optimum
A ProTeX geotechnical engineer’s representative should observe the grading operations to verify that all cut and fill areas are in accordance with the specifications. This office should be notified prior to earthwork operations so that appropriate observation and materials testing can be provided.
When work is interrupted by heavy rains, fill operations should not be resumed until the geotechnical engineer’s representative indicates that the moisture content and density of the previously placed fill are as specified.
If building pads are altered or portions excavated as a part of construction activities, fill soils should be compacted as specified.
6.0 CLOSURE
6.1 Limitations
The recommendations contained in this report are based on the assumption that the subsurface conditions do not deviate appreciably from those disclosed by the test holes. Should unusual material or conditions be encountered during construction, the ProTeX geotechnical engineer should be notified to make supplemental recommendations should this be required? This report is issued with the understanding that it is the responsibility of the owner to see that its provisions are carried out or brought to the attention of those concerned.
The scope of services for this project does not include any environmental assessment of the site or identification of contaminated or hazardous materials or conditions.
The findings of this report are considered valid as of the present date. However, changes in the conditions of the site can occur with the passage of time, whether due to natural events or to human activities on this or adjacent sites. In addition, changes in applicable or appropriate codes and standards may occur, whether they result from legislation or the broadening of knowledge.
Accordingly, this report may become invalidated wholly or partially by changes outside our control.
Therefore, this report is subject to review and revision as changed conditions are identified.
6.2 Recommended Additional Services
The recommendations provided in this report are based on the assumption that a testing plan will be implemented with an adequate schedule of testing to ensure that the construction process meets the recommendations/specifications presented in this report. The testing and observation should be performed under the direction of the ProTeX Geotechnical Engineer/representative and should include, but not necessarily be limited to the following:
1. Observe and document that the existing surface and subsurface structures, vegetation and abandoned utilities are removed from the site as required in the earthwork section.
2. Approve and document that fill material used as engineered fill in building and pavement areas meets the specifications.
3. After clearing the site; monitor the over excavation, scarification and removal of any soft/loose conditions down to firm native soils.
4. Monitor and test placement of fill soils in building and pavement locations to verify and document conformance with project specifications.
5. Inspect foundation excavations to plans and specifications and to be free of loose soils and debris.

ANALYSIS ASSUMPTIONS AND LIMITATIONS
1. The Structural Analysis Report (report) is the property of ISE Services and must not be reproduced, modified or copied in whole or in part without our written permission.
2. The customer must accept all liability and responsibility for the use and application of ISE's review.
Additional services of other Professional Engineering Specialists may be required.
3. The subject tower/Self-Support Tower (structure) is assumed to be installed in accordance with the drawing/s and documents referenced in the report unless otherwise noted. ISE assumes that the structure has been properly maintained and that no portions of the structure have corroded or have been mishandled, overloaded, damaged or substituted with other members. No reduction in capacity has been considered to account for the effects of cyclic loading over the life of the structure. Unless noted otherwise in the report ISE has not inspected or surveyed the loading currently supported by the structure. Unless otherwise indicated in the reviewer's comments, the structure review has been solely based on information listed or referenced in the report.
4. Assumptions made by ISE concerning antenna and appurtenance loading were based on ISE's understanding of the information provided by the customer for the review. Only the antennas and appurtenances listed or referenced in the report were considered for the review unless otherwise noted.
The results of the review are not intended nor represented to be applicable to any other loading conditions.
ISE has not investigated possible interference between existing and proposed antennas, mounts, appurtenances, etc., unless otherwise indicated in the reviewer's comments.
5. ISE has not reviewed the load carrying capability of existing or proposed mounts supplied by others, or of mounts not identified in the report. ISE also has not evaluated members of the structure for local stresses resulting from the attachment of such mounts. ISE can provide this service if requested by the customer.
6. ISE does not accept responsibility for the accuracy or completeness of the information supplied to ISE or for the assumptions made for this review. ISE assumes thorough field investigations have or will be performed by others to verify all information and assumptions used for ISE's review.
7. ISE's review has been based on the wind and ice loading as specified in the ANSI/TIA/EIA-222-H, "Structural Standard for Antenna Supporting Structures and Antennas". The review is limited to the load carrying capacity of the structure for the wind and ice load indicated. Unless otherwise noted in the report, ISE assumes the structure is installed on level grade. Unless otherwise noted in the report, ISE has not reviewed the structure for conformance to local, state, or federal requirements or for site specific requirements concerning wind load, ice load, grounding, obstruction lighting requirements, obstruction marking, climbing or working facilities, etc.
8. Foundation designs have not been reviewed unless reactions exceed the original structure design reactions. Unless otherwise indicated, ISE has assumed that foundations have been installed in accordance with the original foundation drawings and that the original soil parameters provided and/or assumed were adequate based on the conditions encountered at the site. ISE assumes these parameters were verified by geotechnical investigations at the time of installation.
9. ISE's structure and/or foundation review has been performed utilizing ISE's current review methods. ISE does not accept responsibility to provide a new or revised report due to revisions of standards, codes or review methods.
10. ISE does not accept responsibility for work performed on the structure, for persons doing the work, or for the safety and adequacy of the procedures, equipment, temporary guying, scaffolding, or other work aids.
ISE has assumed that all work performed will be by competent and qualified personnel.

11. Materials for proposed additions/alterations are assumed to be manufactured or supplied by reputable manufacturers or as specified in the report. Bolts, nuts, and palnuts for all new/replacement materials must be new. ISE shall be held harmless of any liability when other materials are substituted.
12. If proposed additions/alterations to the structure are implemented, it shall be the responsibility of others to maintain the stability of the structure and to prevent overloading of any component. ISE's review has not considered stresses due to erection since erection conditions were unknown.
13. ISE does not accept responsibility for informing insurance carriers, regulatory officials or other concerned parties of the results of this review or for any proposed alterations.
14. If any of the above assumptions are not valid or have been made in error, this analysis may be affected, and ISE should review any new information to determine its effect on the tower's structural capacity.
