Agenda 03/13/2012 Item #16D23/13/2012 Item 16.D.2. EXECUTIVE SUMMARY Recommendation to approve and authorize structural pilings inspection to the Clam Bay Draw Bridge, approve a budget and a budget amendment of $15,000 to complete this work, and make a finding that improvements to this beach park facility promotes tourism. OBJECTIVE: To inspect the structural pilings of the Clam Bay Draw Bridge CONSIDERATIONS: Annual inspection of the Clam Bay Draw Bridge has identified additional structural inspections that need to be performed. Authorization of this item will allow staff to proceed with the inspection and identify piling repair work if needed. A piling inspection report will be issued as a result of this inspection. Description of work I Estimated Budget Perform Submerged Piling Inspection with Structural Engineer 1 $15,000.00 This item does not include any piling repairs that may result from the submerged piling inspection. In addition it does not include any repairs to the super - structure cleats, blocks, braces or clips; the electrical control unit; hardware; and any work to un- torque the lift /drawbridge section. FISCAL IMPACT: Funding for this project will be from Tourist Development Tax Fund 183 - Beach Park Facilities reserves. A budget amendment in the amount of $15,000 creating the initial Clam Bay Draw Bridge Maintenance budget will be required. The inspection results will be used to develop the balance of the Draw Bridge Maintenance budget. The proposed inspection is a cost of maintaining an existing asset. Additional Clam Pass Draw Bridge maintenance activities that have been identified to date but not yet funded are: Bridge repairs to the super- structure cleats, blocks, braces and clips - $25,000; Un- torque the lift/drawbridge section - $7,500; Replace electrical control unit - $10,000; Replace gates, hardware and reseal wood - $10,000; Engineering /permitting for lift device - $10,000.

We also intended to perform the miscellaneous non - structural, non - critical timber and bolt replacements at the same time. The price for this inspection exceeded $100,000 and the structural engineer indicated that a very adequate in -water structural inspection could be performed at significantly reduced costs. During an inspection of the operations of the boardwalk it was discovered that the bridge mechanism at the span could not be open. This was verified by staff along with damage to the electrical motor that raised and lowered the bridge section. Currently scope is being developed that will address not only the inspection but also the bridge racking and the electrical /mechanical repairs. The scope and budget should be completed next week. Based on what we know now, We expect the cost of the inspection and repairs to be from $75,000 to $100,000. This does not include any significant bridge piling repair and /or replacement. This item will need to go to the TDC for approval later this month and depending on the budget price the BCC in February. Hank Jones from Facilities has also agreed to head this project up and get it accomplished in a timely manner. Gary Under Florida Law, e-mail addresses are public records.

Would require you to arrange for a boat. Would need some kind of water jet. Need to go 3' -4' below mudline and look at piles. My costs would be $250 hour engineer PE diving+ expenses scuba equipment. Not sure number hours involved. Assume 1 -2 piles per 8 hour day.

In our discussion, you indicated that the only way to positively inspect these piers was to open them up and do a physical inspection. We talked about a cofferdam, remove 3 feet of material and do a physical inspection. 9 piers are in the water. Working with Kelly Brothers and PBS, we discussed a 5 or 6 foot diameter metal culvert split in the middle for a cofferdam and access from the top of the bridge because of the shallowness of the water. We would use a mud pump to pump it out and do the inspection. Your firm would do the inspections and recommendations. Problem is permits and the cost. Since this is just an inspection, do we need any permits if we truck the muck from the cofferdam to the landfill and backfill the hole with rock? Packet Page -1293- 3/13/2012 Item 16.D.2.

Fax: (239) 593 -8820 OVERVIEW AND LIMITS OF INSPECTIONIREPORT Cronin Engineering, Inc. conducted an inspection of the above wood tramway /walkway on March 22, 2011. Collier County Coastal Management provided nautical transportation to the tramway to evaluate the existing condition of the wood framing of the tramway. We have not conducted a structural analysis of the tramway at this point in time. VISUAL AND PHYSICAL INSPECTION OBSERVATIONS A visual inspection of the wood framing and hardware of the tramway was conducted. The existing wood framing is approximately 10 years old. Below is a list of the bridge /tramway structural components and the assessed condition. 1. The vertical columns supporting the tramway were pressure treated wood piles. Due to the apparent high grade of pressure treatment of the piles that was visible to the naked eye and physically tested with a knife were found to be in decent condition. See attached photo's numbers 1 -2 on page 3. 2. In the drawbridge area the 4 x 14 pt board knee brace appeared to be in good condition and structurally sound. These members are showing signs of weathering which is common for exterior wood members. The 6 x 6 p.t. members attaching the knee bracing to the 4 x 14 p.t. cross support member appeared to be in good condition and structurally sound. The 3/4" HDG {hot- dipped galvanized} bolts with flat washers and nuts were found to be loose due to the lack of lock nuts and the constant vibration of vehicle and foot traffic. See attached photo's numbers 3- 7 on pages 4 -6. 3. The 3 x 8 p.t members on the west side of the drawbridge waterway were found to be easily penetrated with a knife and appeared to have some degree of rot. See attached photos number #8 on page 6. 4. 4 x 4 p.t. post attaching the tramway beams to the support beams has a split. See attached photo number #9 on page 7. Packet Page -1298- 3/13/2012 Item 16.D.2. 5. The 4 x 14 p.t. board beams that support the tramway appear to be in good condition and structurally sound. See attached photo number #9 on page 7. 6. The p.t. cross - bracing members between the piles appear to be in good condition with the exception on the span on the west side of the drawbridge area. Splitting has occurred where they are attached to south piling. See attached photo number #10 on page 7. 7. The {4} 6" x 6" x 3/8" angle steel connecting the top portion each of the p.t. knee braces appears to be in good condition. See attached photo number #11 on page 8. CONCLUSIONS The existing bridge /tramway wood members appear to be in decent condition for their age. We only require the replacement of the following: 1. All the existing steel hardware such as bolts, nuts, flat washers should be replaced with HDG (hot - dipped galvanized) bolts, nuts and flat washers. Recommend adding HDG lock washers to each of the bolts, nuts, and flat washers. 2. Replace the steel angle clips at the top of the knee braces with one steel angle clip with (3) 3/4" x 8" HDG bolts, nuts, lock washers and flat washers at the top and side attachment points. 3. Replace split cross bracing and add blocking to middle of cross bracing and attach with 3/4" x 12" HDG bolt, nut, lock washer and flat washer. 4. Replace all 3 x 8 p.t. members. 5. Replace all 4 x 4 p.t. posts and hardware. The implementation of a maintenance program of the wood structure such as the addition of a stain every 2 to 3 years will increase the life span of most of the wood components used in the construction of the tramway/bridge. Periodic maintenance of the hardware such as checking for tightness at all the attachment points would cut down on the vibration. Sincerely, Derek P.
