Tower Engineering Professionals (TEP) is pleased to provide this executive summary for the Phase I Scope of Work, which included a Maintenance and Condition Assessment, Capital Expenditure Table, Steel and Appurtenance

Mapping, and Structural Analysis for the above referenced site.

Maintenance and Condition Assessment

Overall Tower Condition (Excellent/Good/Average/Fair/Poor): Average*

Tower Type: 80-ft self supporting tower

Tower Age: Approximately 20-30 years**

Number of Guy Wires: N/A

Tower Access Road Condition: Poor, extremely rocky terrain, all-wheel drive vehicles with high ground clearance necessary

A periodic inspection for the above referenced site was performed by Kyle C. Edwards, P.E., C.W.I. and Andrew E.

Propst of TEP during the July 13, 2016 site visit. The inspection was in accordance with the ANSI/TIA-222-G-2005, Annex J: Maintenance and Condition Assessment (Normative). TEP observed the following checklist items requiring some measure of possible or required corrective action: 1) Structure Condition, 2) Finish, 3) Grounding, 4) Antennas and Lines, 5) Concrete Foundations, and 6) Non-TIA Related Items. Refer to the Maintenance and Condition

Assessment Report for specific details.

*TEP defines the tower conditions as follows:

Excellent - The tower has sufficient capacity to carry the existing loads. No modifications are required at this time. In addition, the tower has no maintenance issues of note and doesn’t require maintenance repairs at this time.

Good - The tower has sufficient capacity to carry the existing loads. No modifications are required at this time. However, the tower has some maintenance issues of note that require attention.

Average - The tower does not have sufficient capacity to carry the existing loads. Modifications will be required to bring the tower into compliance with the

ANSI/TIA-222-G standard for the existing loading. In addition, the tower may have minor maintenance issues of note that require attention.

Fair - The tower does not have sufficient capacity to carry the existing loads. Modifications will be required to bring the tower into compliance with the

ANSI/TIA-222-G standard for the existing loading. In addition, the tower has maintenance issues of note that require attention. Based on the itemized estimate in our Capital Expenditure Table, modifying the existing tower may be the most cost effective solution.

Poor - The tower does not have sufficient capacity to carry the existing loads. Modifications will be required to bring the tower into compliance with the

ANSI/TIA-222-G standard for the existing loading. In addition, the tower has maintenance issues of note that require attention. Based on the itemized estimate in our Capital Expenditure Table and/or the condition of the tower, a full tower replacement may be the best solution.

**Tower Age was estimated based on tower identification tags, tower manufacturer information, tower research, type and condition of tower components, and/or historical site images

Condition Assessment of Non-Tower Assets

During the site visit, TEP conducted a visual inspection of all Non-Tower Owned Assets. TEP did not find any non-tower assets that require urgent corrective repairs. However, TEP recommends regular inspection and maintenance by licensed professionals based on manufacturer specifications. Refer to Section L of the Maintenance and Condition

Assessment Report for any applicable additional information.

Capital Expenditure Table

A cost estimate of $24,950 was provided to cover repairs and additional inspections as recommended in the

Maintenance and Condition Assessment Report and the Structural Analysis Report. The recommended repair schedule ranges from 6 months to 5 years. Also note that this estimate does not include any foundation reinforcements that may be required. TEP cannot say with certainty that modifying the existing tower would be more cost effective than a replacement without completing a Structural Modification Design Analysis. Refer to the

Capital Expenditure Table for details. For itemized repairs, refer to the Capital Expenditure Table for details. TEP estimated a ROM cost for full tower replacement would range from approximately $160,000 for a 100-ft self supporting tower to $250,000 for a 200-ft self supporting tower. These estimates do not include pricing for site specific costs related to zoning, permitting, environmental studies, etc.

Steel and Appurtenance Mapping

The original design criteria were unavailable for review. A Steel and Appurtenance Mapping was performed in order to obtain the necessary tower and appurtenance loading information needed to conduct the Structural Analysis for this site. The antennas recorded during our Steel and Appurtenance Mapping are depicted in the table below. TEP denoted the owner of the equipment under the “Owner/Tenant” column based on information available on site.

Structural Analysis

The Structural Analysis report outlines overstresses in the tower diagonal bracing from 0’ to 39’ elevations. TEP believes that the majority of the overstresses can be attributed to the more stringent loading and analysis criteria as required by the latest ANSI/TIA-222-G-2-2009 Standard, as compared to previous versions of the TIA Standard for which the tower was originally designed. Based on our analysis we have determined the tower stress level for each controlling component, under the following load case, to be:

Dear Mr. Fiskum, Tower Engineering Professionals (TEP) completed a periodic inspection for the above referenced site. The onsite investigation was performed by Kyle C. Edwards, P.E., C.W.I. and Andrew E. Propst of TEP during the July 13, 2016 site visit. The inspection was in accordance with the ANSI/TIA-222-G-2005, Annex J: Maintenance and Condition Assessment

(Normative), including all addendums (addendums TIA-222-G-1 2007 and TIA 222-G-2 2009); the checklist can be found on pages 3 thru 8 of this report.

Observations and recommendations are listed herein. The inspection included observation of the tower components and CBP owned assets. For the purpose of this inspection, the tower legs were named by letter according to the magnetic azimuth defined by a line from the center of tower to the leg. “A” leg is the leg closest to magnetic north, followed clockwise by “B” and “C.”

Thank you for the opportunity to provide this service for you. If you have any questions or comments, please contact our office.

SUMMARY

Photograph Observations and Recommendations

A.4. Climbing facilities, platforms, catwalks (all secure)

Observation:

Missing nut locking device on ladder hardware at 59-ft.

Safety climb cable cap is missing.

Recommendation:

Install a nut locking device. If necessary, re-install a longer bolt to accommodate the use of a nut locking device. Tighten all nuts per the AISC "turn of the nut" method.

Replace safety climb cable cap.

Site Data: N. Tower Road, Buckeye, Maricopa County, AZ 85326 Lat., Long.: 33.575406, -112.578769 (N 33° 34' 31.46'', W 112° 34' 43.57'') 80 Foot ± - Self Supporting Tower Dear Mr. Fiskum, Tower Engineering Professionals is pleased to submit this “Structural Analysis Report” to determine the structural integrity of the above mentioned tower.

The purpose of the analysis is to determine acceptability of the tower stress level. Based on our analysis we have determined the tower stress level for the structure and foundation, under the following load case, to be:

LC1: Existing + Proposed + Reserved Loading Insufficient Capacity Note: See Table 1 for the existing, proposed, and reserved loading

The analysis has been performed in accordance with the ANSI/TIA-222-G-2-2009 Structural Standard for Antenna Supporting Structures and Antennas – Addendum 2 and the 2012 International Building Code.

All modifications and equipment proposed in this report shall be installed in accordance with the appurtenances listed in Table 1 for the determined available structural capacity to be effective.

We at Tower Engineering Professionals appreciate the opportunity of providing our continuing professional services to you and HGA Architects and Engineers. If you have any questions or need further assistance on this or any other projects please give us a call.
