A. RESULTS This analysis was performed by ERI to review the present structure’s condition and capability to comply with past and present design standards to determine the feasibility of modifying/repairing versus decommissioning. This report details the tower history, the present design code requirements and application, and the impact of the wind speed and appurtenances on the structure. The ERI analysis finds:

1. Severe corrosion was noted throughout the tower mast. A summary of the critical locations found during the climbing inspection conducted October 23-24, 2013, are summarized in Appendix II, Pictures 45-92, and in Appendix III. All locations highlighted in red in Appendix III should immediately be replaced or have temporary bracing installed due to the severity of material loss. In addition, ERI strongly recommends at least (6) additional replacement diagonals and at least (12) additional horizontal reinforcement assemblies be provided for bracing additional locations which may be noted once the structure is rigged. Also, all missing and corroded u-bolt assemblies used to secure the climbing ladder should be installed/replaced to provide safe climbing access and all unused equipment should be removed from the tower to reduce imposed loading until the tower is decommissioned.

2. Plans should be made to deconstruct the existing tower as soon as possible to ensure the

structure may be safely destacked utilizing “normal” construction practices without substantial risk of potential damage to adjacent properties. The level and extent of corrosion noted throughout the mast coupled with design limitations (i.e. pipe members experiencing internal corrosion which cannot be mitigated reliably) makes potential reinforcement of the structure complex and unreliable without bearing enormous financial expenditures.

3. Considering only the existing equipment as specified in Section F of this report and

assuming all structural members intact with no strength reductions considered due to current condition, the structure is NOT within compliance of the original EIA-RS-222, Structural Standards for Steel Transmitting Antennas, Supporting Steel Towers for Transmitting Antennas and Steel Microwave Relay System Towers (effective from 1959 to October 1966) for a constant wind pressure of 50 pounds per square foot. Please note, all structural analyzes and subsequent modifications performed should have been conducted in direct accordance with current design standards at the time the evaluations were conducted. The latest study provided to ERI for reference was done in 2008, and should have reviewed the structure in accordance with the ANSI/TIA-222-G standard.

4. In order to determine if structural upgrades should be pursued for the existing tower to

prolong the serviceable life, ERI also reviewed the tower in accordance with the current 2010 Florida Building Code and ANSI/TIA-222-G, Structural Standard for Antenna Supporting Structures and Antennas, for an ultimate design wind speed of 140 mph (Risk Category II, Exposure Category C, and Topographic Category 1). Results of this review confirm upgrading the existing tower to meet current Florida Building Code requirements is NOT a viable option.

B. METHOD OF ANALYSIS We have analyzed this tower based upon the following information:

1. ERI tower inspection conducted 10/23-24/2013 (no. 31728). 2. Structural Analysis by Stainless, LLC, dated 1/3/2008 (no. 174510).

3. Tower Erection Drawings by Stainless, Inc., dated 2/2/1966 (no. 1745).

4. Tower Calculations by Stainless, Inc., dated 1/19/1966 (no. 1745). 5. Written and oral communication with Max Sitero representing WUSF Public

Broadcasting. 6. Published data for antenna/appurtenance loading.

C. TOWER HISTORY The tower was originally designed and manufactured by Stainless, Inc., in 1966. The structure was originally designed under the EIA-RS-222, Structural Standards for Steel Transmitting Antennas, Supporting Steel Towers for Transmitting Antennas and Steel Microwave Relay System Towers (effective from 1959 to October 1966) for a constant wind pressure of 50 pounds per square foot. *In May of 1980, the tower was modified by Stainless per order number 174503, which included reinforcement of the vertical tower leg members in (4) bays from 817.1’-848.0’. *In November of 1994, the tower was modified by Stainless per order number 174507, which included replacement of the lower two guy levels, adjustments to guy tensions, and replacement of (4) bays of diagonal inner members from 133.8’-142.1’ and 267.1-292.1’. *In September of 2006, the tower was modified by Stainless per order number 174509, which included adjustments to guy tensions. The 2008 Stainless analysis considered the addition of the top Dielectric DCR-M8 FE87N10T5P, and ultimately recommended only adjustments to guy tensions in order to retain a uniform 50 psf wind load rating. As previously stated, ALL structural analyzes and subsequent modifications performed should have been conducted in direct accordance with current design standards at the time the evaluations were conducted. *NOTE: Historical information based upon the 2008 Stainless analysis report (no. 174510).

D. CURRENT DESIGN CRITERIA The current design criteria based upon the 2010 Florida Building Code and the ANSI/TIA-222-G, Structural Standard for Antenna Supporting Structures and Antennas, is summarized in the following table. Applicable design parameters were established through communication with the customer and a review of the local site topography.

Current 2010 FBC & ANSI/TIA-222-G Criteria Design Wind Speed 140 mph (Ultimate)

108.4 mph (Nominal) Service Wind Speed 60 mph (Nominal) Risk Category II Exposure Category Category C Topographic Category Category 1

The tower owner or their representative is required to contact state and/or local building officials to verify the design parameters comply with all local standards and codes. E. ASSUMPTIONS/LIMITATIONS This analysis is based on the theoretical capacity of the structure. It is not a condition assessment of the tower. In offering this report, the following assumptions/limitations apply due to insufficient provided documentation, and/or omission from the contracted scope of work:

1. Customer supplied information assumed accurate and correct. The Discrete (appurtenant) Tower Loads are shown on the following pages. Antenna and appurtenance loading is also portrayed on drawing E-1. These should be checked for accuracy and any corrections communicated to ERI.

2. Transmission lines assumed distributed on the tower as portrayed in Figure 1 and

drawing E-7. Feed distributions should be checked for accuracy and any corrections communicated to ERI, as deviation would result in wind-loading not considered in this analysis.

3. Analyzed steel minimum yield strengths (Fy) were based upon specifications provided in

the 1966 Stainless structural analysis and typical steel grades used by Stainless during the time this structure was manufactured. ERI can make no certain determination as to the actual steel grades used in this particular structure without reviewing individual steel mill certificates, and strongly recommends the customer contact the original tower manufacturer for verification. Steel strengths used in this analysis are as follows:

Description Minimum Yield Strength

(ksi) Tower Leg Members: Pipe (Wall Thickness < 3/8”) 50 Pipe (Wall Thickness > 3/8”) 60 Tower Inner Members: Solid Rod 60 Pipe 50 Angle/Channel 36 Structural Bolts: (A325)

4. Tower mast and supported pylons assumed plumb with no twist. As-built plumb and

twist should be checked and corrected as necessary to within the tolerances designated in Section 13.0 of the ANSI/TIA-222-G standard.

5. Guy wires assumed properly tensioned to the values specified in this report. Please note,

the initial tension settings have a significant impact on the overall stability and distributed stresses within the main lattice mast under design wind and ice loads. As-built guy tensions must be verified and adjusted as needed to validate the results of this study. Initial guy tension settings shall be within ±10% for guy cables up to and including 1”Ø, and ±5% for cables greater than 1”Ø.

6. This analysis assumes the structure was erected and maintained in accordance with the

manufacturer’s plans and specifications and those contained in the latest version of the ANSI/TIA standard. The tower and foundations are assumed to be in good condition and without defect.

7. The extent of work for the subject structural analysis is limited to the overall stability and

adequacy of the main lattice tower structure. A rigorous analysis was specifically not conducted on the following items due to lack of provided information, and/or omission from the scope due to the level of overstress found in the primary structural elements:

a. Bolted joints (assumed to carry the full capacity of the connected members) b. Welded joints (assumed to carry the full capacity of the connected members) c. Supporting foundations and soil conditions d. Supported antennas and mounts

G. INSPECTION NOTES The following list identifies the maintenance issues noted during ERI’s site climbing inspection done October 23-24. 2013, along with the proposed corrective actions (CA):

1. ISSUE: Primary structural tower members exhibit moderate to severe corrosion throughout the tower mast. Active corrosion is most prominent in the orange banded sections in the upper 3/4’s of the lattice structure. The following table summarizes the locations throughout the tower mast where structural members have experienced significant material loss which would require reinforcement/replacement should the structure be modified for continued use:

LOCATION NO. OF COMPROMISED LOCATIONS Top RCA TV Pole (Base Flange Bolts Severely Corroded)

Wedding Cake Interface (Material Loss Noted on Leg/Inner Members) Top FM Support Pole (Isolated Rust Locations on Pole Mast & Rusted Index Plate) Tower Section Legs (2) Locations With Corrosion & Dent Noted in Section 34 (Has Reinforcement)

Tower Section Diagonals (196) Members of Which (7) Require Immediate Replacement Tower Section Girts Approx (97) Members of Which (27) Require Immediate Reinforcement

REF. PICTURE(S): 45-89 PROPOSED CA: The noted (7) diagonal inner members and (27) horizontal girts should be replaced/reinforced immediately due to their severely degraded condition. In addition, ERI recommends at least (6) additional replacement diagonals and at least (12) additional horizontal reinforcement assemblies be provided for bracing additional locations which may be flagged once the structure is rigged. If the serviceable life of the structure is to be extended beyond the next year, all remaining structural members with moderate corrosion should be replaced or reinforced, and ERI strongly recommends ALL pipe horizontal inner members be replaced due to their inherent thin steel walls and questionable integrity.

2. ISSUE: Approximately (4) Ø1/2”x3-1/8” u-bolts used to secure the ladder angle brackets to the pipe horizontal girts are severely corroded, and approximately (40) Ø3/8”x1-1/2” u-bolts used to secure the ladder rails to the ladder angle brackets are missing or severely corroded. REF. PICTURE(S): 90-92 PROPOSED CA: All missing and severely corroded u-bolt assemblies should be replaced.

3. ISSUE: The existing Ø3/8” safety cable is moderately corroded. REF. PICTURE(S): 93 PROPOSED CA: A new safety cable should be installed.

4. ISSUE: The existing paint in many areas throughout the mast and the upper orange bands have blistered/peeling paint which is holding moisture and accelerating the corrosion rate of the structural members. In addition, numerous partial to complete blockages were noted at drilled weep holes in the pipe horizontal girts which prevents moisture drainage and positive air ventilation. REF. PICTURE(S): 94-95 PROPOSED CA: The structure should be thoroughly cleaned to remove loose/peeling paint and rust, cold-galvanized at locations experiencing active corrosion, and repainted in accordance with ASTM A780 and FAA regulations.

12

5. ISSUE: Loose wrap locks used to secure the diagonal crossover points were noted

throughout the structure. REF. PICTURE(S): 96 PROPOSED CA: All wrap locks should be removed and replaced with new stainless steel hose clamps to properly tie the diagonals.

6. ISSUE: Grease on all guy cables is degraded and wires in levels 3-6 show signs of surface rust and initial pitting where grease has worn off (primarily at tower end) REF. PICTURE(S): 97 PROPOSED CA: All guy cables should be adequately cleaned and re-greased.

7. ISSUE: Guy anchor fan plates are partially buried at the inner and outer NE anchors and moderate rust was noted on the underneath side of the plates from being in direct contact with the ground. REF. PICTURE(S): 98-99 PROPOSED CA: Anchor fan plates should be cleared and affected rust areas treated and cold galvanized in accordance with ASTM A780.

8. ISSUE: Grounding systems at the tower base and all guy anchor points (with the exception of the outer NW anchor) are in poor condition with inadequate electrical connections and many locations read open loops. REF. PICTURE(S): 100 PROPOSED CA: New grounding systems should be installed exhibiting a maximum ground resistance of 10Ω at the tower base (5Ω or less is preferred) and 25Ω at each guy anchor location (10Ω or less is preferred) to provide adequate protection from potential lightning currents. New ground system leads at the tower base should utilize all exothermic welds, and additional leads should be provided from the guy anchor fan plates to the driven electrodes again utilizing exothermic welds in addition to the drop leads connected to the guy cables.

9. ISSUE: Very little take-up is available for adjusting guy tensions in level 3 at the NW anchor point, and no take-up is available in level 3 at the S anchor point. REF. PICTURE(S): 102-103 PROPOSED CA: No CA is warranted unless guy tensions need to be increased in guy level 3 which would necessitate installing new end terminations at the NW and S anchors.

10. ISSUE: Loose, disconnected, and/or missing transmission line attachment hardware was noted throughout the structure. REF. PICTURE(S): N/A PROPOSED CA: All active lines should be thoroughly inspected and attachment repaired or replaced as needed.

11. ISSUE: The tower currently supports several unused/nonoperational pieces of equipment including antennas, transmission lines, etc. REF. PICTURE(S): N/A PROPOSED CA: All inactive equipment should be identified and removed from the structure to relieve unnecessary loading on the tower.

13

12. ISSUE: The top TV antenna is out-of-plumb. REF. PICTURE(S): 29-30 PROPOSED CA: The top Ch.16 RCA antenna is inactive and should be removed, or plumbed if it is to remain on the structure.

I. CONCLUSIONS 1. Severe corrosion was noted throughout the tower mast. A summary of the critical

locations found during the climbing inspection conducted October 23-24, 2013, are summarized in Appendix II, Pictures 45-92, and in Appendix III. All locations highlighted in red in Appendix III should immediately be replaced or have temporary bracing installed due to the severity of material loss. In addition, ERI strongly recommends at least (6) additional replacement diagonals and at least (12) additional horizontal reinforcement assemblies be provided for bracing additional locations which may be noted once the structure is rigged. Also, all missing and corroded u-bolt assemblies used to secure the climbing ladder should be installed/replaced to provide safe climbing access and all unused equipment should be removed from the tower to reduce imposed loading until the tower is decommissioned.

2. Plans should be made to deconstruct the existing tower as soon as possible to ensure the

structure may be safely destacked utilizing “normal” construction practices without substantial risk of potential damage to adjacent properties. The level and extent of corrosion noted throughout the mast coupled with design limitations (i.e. pipe members experiencing internal corrosion which cannot be mitigated reliably) makes potential reinforcement of the structure complex and unreliable without bearing enormous financial expenditures.

3. Considering only the existing equipment as specified in Section F of this report and

assuming all structural members intact with no strength reductions considered due to current condition, the structure is NOT within compliance of the original EIA-RS-222, Structural Standards for Steel Transmitting Antennas, Supporting Steel Towers for Transmitting Antennas and Steel Microwave Relay System Towers (effective from 1959 to October 1966) for a constant wind pressure of 50 pounds per square foot. Please note, all structural analyzes and subsequent modifications performed should have been conducted in direct accordance with current design standards at the time the evaluations were conducted. The latest study provided to ERI for reference was done in 2008, and should have reviewed the structure in accordance with the ANSI/TIA-222-G standard.

4. In order to determine if structural upgrades should be pursued for the existing tower to

prolong the serviceable life, ERI also reviewed the tower in accordance with the current 2010 Florida Building Code and ANSI/TIA-222-G, Structural Standard for Antenna Supporting Structures and Antennas, for an ultimate design wind speed of 140 mph (Risk Category II, Exposure Category C, and Topographic Category 1). Results of this review confirm upgrading the existing tower to meet current Florida Building Code requirements is NOT a viable option.

J. RECOMMENDATIONS

1. All assumptions made in this analysis should be carefully reviewed and any discrepancies or corrections communicated to ERI for comprehensive assessment.

2. All structural changes made to the tower should be performed by professionally trained

individuals in tower erection and post-erection modifications.

3. This analysis does not consider localized stresses on tower members resulting from the use of lifting equipment, rigging, or modifications which may be necessary during the course of installing new appurtenances on the structure. For maximum concern to safety and tower service life, ERI recommends an engineering review for all proposed lifting plans and/or special construction considerations prior to the commencement of work.

4. An ongoing tower maintenance program should be implemented for this site until the

structure can be decommissioned. Ground inspections should be conducted at least weekly, and thorough climbing inspections should be conducted after any significant tower loading event associated with moderately high winds (i.e. above 60 mph), heavy rigging, vandalism, etc. A complete list of the standard maintenance and inspection procedures is contained in Annex J of the ANSI/TIA-222-G standard.

TOWER INSPECTION SUMMARY Based upon the ERI inspection performed August 29, 2014, and previous inspection and analysis conducted in October/November of 2013 (ERI project 31728/A), the current condition of the tower warrants complete replacement as soon as possible. It is imperative the structure be decommissioned while it is still safe to rig to allow the tower to be destacked utilizing “normal” construction practices without substantial risk of potential damage to adjacent properties. Until the tower is safely deconstructed, an ongoing maintenance program should be implemented. General ground inspections should be conducted at least weekly, and thorough climbing inspections should be conducted after any significant tower loading event associated with moderately high winds (i.e. above 60 mph), heavy rigging, vandalism, etc. A complete list of the standard maintenance and inspection procedures is contained in Annex J of the ANSI/TIA-222-G standard. The following items highlight the main structural issues noted during the recent onsite climbing and ground inspections (reference previous ERI analysis report 31728 dated November 1, 2013, for additional information):

ISSUE 1. Primary structural tower members exhibit moderate to severe corrosion throughout the tower mast. Active corrosion is most prominent in the orange banded sections in the upper 3/4’s of the lattice structure. A total of (39) horizontal braces and (13) replacement diagonals were previously installed in February of 2014. An additional (18) horizontal braces and (8) replacement diagonals are needed due to progressive material loss since last year. The following table identifies the noted locations requiring reinforcement:

ISSUE 2. Tower members in many areas throughout the mast and the upper orange bands

have blistered/peeling paint which is holding moisture and accelerating the corrosion rate of the members. In addition, numerous partial to complete blockages were noted at drilled weep holes in the pipe horizontal girts which prevents moisture drainage and positive air ventilation. REF: Pic 41

ISSUE 3. Loose wrap locks used to secure the diagonal crossover points were noted

throughout the structure. REF: Pic 42

ISSUE 4. Loose, disconnected, and/or missing transmission line attachment hardware was

noted throughout the structure. REF: N/A

ISSUE 5. The tower currently supports several unused/nonoperational pieces of equipment

including antennas, transmission lines, etc. REF: N/A

ISSUE 6. The existing Ø3/8” safety cable is moderately corroded.

REF: Pic 43

ISSUE 7. Grease on all guy cables is degraded and wires in levels 3-6 show signs of surface rust and initial pitting where grease has worn off (primarily at tower end) REF: Pic 44

ISSUE 8. Guy anchor fan plates are partially buried at the inner and outer NE anchors and

moderate rust was noted on the underneath side of the plates from being in direct contact with the ground. REF: Pic 45-46

ISSUE 9. Grounding systems at the tower base and all guy anchor points (with the

exception of the outer NW anchor) are in poor condition with inadequate electrical connections and many locations read open loops. REF: Pic 47

ISSUE 10. Very little take-up is available for adjusting guy tensions in level 3 at the NW anchor point, and no take-up is available in level 3 at the S anchor point. REF: Pic 48-49

ISSUE 11. The top TV antenna is out-of-plumb.

REF: Pic 50

ISSUE 12. Anchor fencing and entry gate at the inner SE anchor point is damaged. REF: Pic 51-52
