SECTION 1 INTRODUCTION
1.1 PROJECT OVERVIEW Edge Consulting Engineers, Inc. (Edge) has been engaged by the State of Wisconsin Department of Natural Resources (Client) to perform a structural condition assessment of the existing observation tower structure at the Peninsula State Park located in Fish Creek, Wisconsin. 1.2 PURPOSE OF REPORT The purpose of this assessment was to examine and comment on the condition of the structural components of the existing structure. The assessment is also intended to provide recommendations for repair of the structure. 1.3 SCOPE OF SERVICES The scope of services for this project included a field inspection of the existing observation tower to assess its current condition, core samples to visually inspect for signs of rot and decay, a structural model of the existing structure and a report to document our findings, opinions and recommendations. The project was completed in conformance with a client agreed upon scope of work, and utilizing the judgment of the structural engineer. The field review was limited to areas and elements that were determined to be accessible at the time of the inspection. Elements concealed by non-structural elements were not reviewed. A non-destructive approach was used throughout accessible areas; although some core samples were collected and observed as part of this project for the tower legs and timber support members. Recommendations and comments are based on the review conducted through the field inspection conducted on April 22, 2015. The following recommendations have been made as based on current standards and our accumulated knowledge and experience. This Structural Condition Assessment report has been prepared for the intended and exclusive use of Edge Consulting Engineers, Inc. and Client.

SECTION 2 INVESTIGATION
2.1 BACKGROUND The existing observation tower structure is located at Peninsula State Park on the bluffs over Lake Michigan. The current tower was built in 1932 to replace the structure originally constructed in 1914. Modifications believed to have been completed in the1980’s to the existing tower include replacement framing that has been installed for the first and third levels. Plans for the original construction of the tower could not be located and were not available for use in our assessment. All subsequent work on the tower has been limited to minor maintenance and repairs. 2.2 DESCRIPTION OF EXISTING STRUCTURES The existing observation tower structure is a 5 legged timber structure which is approximately 76 feet tall and includes 3 levels of lookout platforms (30’, 51’ & 72’). There is an interior stair system which wraps the interior support column. The interior support column is a series of timber members that decrease in size with elevation; 12x12” at the tower base to 10x10” at the third level. The stair stringers are supported with a series of 6x6” posts at the tower base and 4x4” hangers from platform levels above. No information was available regarding the concrete footings for the interior support column or stair support posts. The four exterior legs are continuous timber columns that taper with elevation; 18.5” dia. at the tower base and 11.5” dia. at the third level. All columns bear directly on concrete footings and are attached by steel hardware. The four exterior columns include steel tie rod X-bracing between each platform level to provide lateral support. The steel tie rod X-bracing for the first level, second level and third level were measured to be approximately 1 1/8”, 1” and 7/8” in diameter respectively. No information was available regarding the concrete footings for the exterior columns. The first level platform level is supported by (2) 8x8” treated timber beams spanning east-west (EW) connected to the exterior of the columns with steel hardware. Two (2) 8x8” treated timber edge joists spanning north-south bear on the EW timber beams and are connected are to the exterior of the columns in the opposite direction. Doubled-up 2x12” treated lumber joists spanning north-south bear on the EW timber beams on the interior of each platform and are spaced approximately 16-inches O.C. The joists are topped with 2x8” treated lumber deck boards. The second level appears to be part of the1932 tower construction. The second level platform level is supported by (2) 8x8” timber beams spanning east -west connected to the exterior of the columns with steel hardware. Two (2) 8x8” timber edge joists spanning north-south bear on the EW timber beams and are connected are to the exterior of the columns in the opposite direction. Additional 3”x8” joists bear on the EW timber beams on the interior of each platform and are spaced approximately 16-inches O.C. The joists located on the east side of the second level also have been modified with additional 2x6” joist members. The joists are topped with 3x8” timber deck boards. The third level platform level is supported by (2) 8x8” timber beams spanning east-west (EW) connected to the exterior of the columns with steel hardware. Two (2) 8x8” timber edge joists
8016-12_Condition Assessment Report_2015-05-20.docx Edge #8016-12 -3-
spanning north-south bear on the EW timber beams and are connected are to the exterior of the columns in the opposite direction. Single 2x12” treated lumber joists spanning north-south bear on the EW timber beams on the interior of each platform and are spaced approximately 16-inches O.C. The joists are topped with 2x8” treated lumber deck boards. The first level platform has a railing system consisting of 4x4” treated posts spaced approx. 5’ O.C. 2x8” treated rails and a 2x8” top rail. The second level platform has a railing system consisting of 4x4” timber posts spaced approx. 5’ O.C. and 3x6” timber rail members. The third level platform has a railing system consisting of 4x4” treated timber posts spaced approx. 6’ O.C. and 2x6” rail members. All three railing systems are approximately 44” in height. The stair system includes a series of landings which wrap the main interior column. The timber stair system consists of 3x12” stair treads approximately 29” wide supported by 3x8” stair stringers and 3x8” joists at stair landings. The stairs and landings are supported in three ways: main interior timber column, (2) additional 6x6” timber columns on either side of the stair system and hanging 4x4” supports from the platform levels above. 2.3 FIELD OBSERVATIONS Our field inspection was completed on April 22, 2015. Photos from this inspection have been included in Appendix A. At the time of the inspection the tower main structural components (columns, beams & deck), where visible, generally appeared to be in good condition. Some deck boards were deteriorated or otherwise damaged and needed replacement. A total of twelve (12) cores were taken on the tower structure; eight (8) from the tower legs and two (2) from 8x8” EW timber support members. A 2-1/2” void and a 4-1/2” void were detected at the base of the NE and SW tower columns respectively. An additional core was completed approximately 20’ above ground level on the NE tower leg just above an area with notable damage and a 2” void was detected. No voids were detected at the base of the NW and SE tower columns at the tower base. No voids were detected in the 8x8” treated timber member of the first level platform or 8x8” timber member of second level platform. In addition, several column members had checking cracks up to ½” in width but otherwise appeared to be in sound condition. It should be noted that our investigation of the column condition was based on visual inspection and a limited number of cores. Additional testing procedures including (radiograph and/ stress wave propagation testing) would be necessary to provide better insight as to the degree and severity of the deterioration of these support members. The tie rod X-bracing between columns was found to be extremely loose which is allowing the overall structure to move excessively in the wind and is causing hardware and fasteners throughout the structure to loosen. Overall structure movement was noticeable at the top level when utilizing weight shift of two individuals. The stair system and protective railings were generally found to be in fair to poor condition throughout the structure. These items included severely deteriorated and missing members, loose hardware and inadequate and inconsistent installation throughout. Several stair treads were severely deteriorated and in need of replacement. The 6x6” timber column stair supports have split down the middle and in need of replacement. The hanging 4x4 supports were all severely
8016-12_Condition Assessment Report_2015-05-20.docx Edge #8016-12 -4-
deteriorated/dry rotted and in need of replacement. The structural adequacy of the several modifications to the hanging 4x4 supports that have been installed is indeterminate. In addition, several railings had bowed/damaged members and many top rails did not have adequate support.

SECTION 3 REMARKS
3.1 MODELING & DESIGN LOADS Using measurements obtained at the time of our inspection, the existing observation tower structure was modeled and evaluated to determine its adequacy. The original design loading criterion was not available for the tower structure and is unknown. As a result, loading conditions in accordance with current building code requirements (IBC 2009/ASCE7-05) were utilized. The following are the superimposed loads utilized in our analysis:

Capacity - Results
It should be noted that the modeled members were assumed to be in a new, non-deteriorated condition. The weathered and deteriorated condition of the tower timber members will indeed reduce their overall capacity; however we are not able to definitively determine how much of an effect this plays based on current information. Additional testing procedures including (radiograph and/ stress wave propagation testing) could be done to provide better insight as to the degree and severity of the deterioration. The original tower foundation designs were not provided at the time of this investigation. Therefore, no analysis was performed and no recommendations were formulated in regards to the adequacy of the towers foundations. See Appendix C for structural calculations.
8016-12_Condition Assessment Report_2015-05-20.docx Edge #8016-12 -7-
3.2 RECOMMENDATIONS Based on our field inspection and analysis, it is our opinion that the existing observation tower structure is not structurally adequate to support the superimposed loading conditions and should not be utilized in its current condition. The original design loading criterion was not available for the tower structure and is unknown. As a result, loading conditions in accordance with current building code requirements (IBC 2009/ASCE7-05) were utilized. From analysis, the tower structure could handle a live load of approximately 30-40 psf. However, the lateral bracing provided by the steel tie rod X-bracing would still be inadequate for the design code related wind loading. After speaking with members of the park staff regarding the volume and magnitude of traffic from the public for the tower structure, a live load of 100psf is more appropriate to depict the expected loading the tower structure would experience. Given the age of the tower structure, condition of the structural members and inadequate connections, modification of the existing tower structure is not recommended as a viable option to address the structural deficiencies identified. We recommend that the tower structure be closed to the public, razed and a new tower be constructed that will adequately support the expected loading conditions.
