Re: Sylvan Beach Pavilion Floor System Dear Mr. Kneupper. .'" This is to record my visual observation of the condition of the floor system of the referenced building. I've also included recommendations for repairs. EXECUTIVE SUMMARY Visual observation of the underside of the elevated floor structure revealed that the reinforcing steel in the beams and joists has begun to corrode from exposure to salt air. The corrosion is causing the steel to expand and spall the concrete cover off of the reinforcing. This of course leads to acceleration of the process. The area under the building needs to be barricaded until all loose concrete can be removed to prevent a hazard from falling debris. The structure needs to be thoroughly deaned to remove all loose concrete and expose all cracks. The cracks must be sealed by injection of urethane sealant; the reinforcing steel must be thoroughly cleaned of corrosion and coated with an anti-corrosion bonding agent and the spalJs must be replaced with a cement and sand aggregate mortar to restore the cover on the reinforcing steel. All the exposed surfaces of the concrete must be coated with an elastomeric waterproof coating to seal them against salt air intrusion. It may be necessary to clean and recoat the exposed surfaces approximately every five years. REPORT The Sylvan Beach Pavilion was visited on April 23, 1998 in the company o( Mr. Doug Kneupper and Mr. Reagan McPhail. The visit was made at the request of Mr. Kneupper. The purpose of the visit was to observe and report on the condition of the floor structure and to make recommendations for repairs. The weather was clear, sunny and the temperature was in the eighties. The building is elevated above the ground and the soffit of the main floor is about 8 or 9 feet above the.ground. The structure is positioned immediately behind the seawall in very dose proximity to the bay. The building is constantly exposed to salt air. The structure is reinforced concrete pan joist and beam framing supported on reinforced concrete columns. The foundation system is not known but it is probably driven piles. No indications of excessive deflection, foundation settlement or overstressing of the structure were visually apparent. AFFILIATE OFFICES IN: ROClCVlu.e. MAFM.ANO . PHILACE1.PHIA. PENNSVUlANIA o . ': . .., . American Consulting Englnee,.. Council Member - . .SYlva~ ~each Pavilion Floor .Sy8 e 2 Spalls on the bottom of joists and beams were observed as well as horizontal cracks near the bottom of joists were observed at many locations. The concrete appears to be lightweight aggregate and normal weight sand, Portland cement concrete. No vertical or diagonal tension cracks were observed. Diagonal cracks were seen in a spandrel at the ends of some cantilevered joists but these are thought to be related to corrosion of the reinforcing where a wood deck was bolted to the spandrel. One or two areas of spalling concrete were removed but many had fallen prior to this visit. The attached photographs illustrate the distress il)Jhe-concrete that was observed. The bottom reinforcing bars in the joists and at the bottom edges of beams are exposed 'at the concrete spa lis. The bars are surface corroded but it appears that there has been very little lose in the cross section of the steel, so far. The steel has definitely corroded enough however to cause the concrete spalls from the expanding oxidized metal. The present conditions are dangerous to pedestrians that can walk beneath the b'uilding. The spalling concrete is about 1'% inches thick and appears to fall In pieces 6- wide by lengths varying from 1 to 2 feet. These pieces could definitely cause minor injury at best and major injuries if a person was hit in the eye. We recommend that the area under the building be barricaded immediately to prevent persons from ~alking beneath it until repairs are completed. . The repairs should be completed as soon as possible to mitigate the deterioration of the structure before it jeopardizes the structural integrity of the building. RECOMMENDED REPAIR The repairs should include the following procedure: 1. Remove loose concrete from spalls. 2. Sand blast the entire exposed surface of th~ concrete and remove all loose concrete. 3. Repair any diagonal tension cracks that may be found with injection of low viscosity epoxy (SIKA OUR HIMOO LVL). 4. Sand blast and remove all corrosion from exposed reinforcing steel to biight metal. 5. Immediately coat the clean steel and the clean spalled concrete surfaces with SIKA ARMA TEe 110 for inhibiting corrosion and to provide a bonding agent for the patch described'below. 6. Apply a mixture of sand/cement grout and micro silica by the shot-crete method to rebuild the concrete to the original dimensions. Finish the shot-crete by troweling it to the original dimensions and to close and densify the surface of the patch. The patch must be applied within 8 hours of the sand blasting of the steel. Therefore, the repairs must be done in sections of sizes that can be started and completed in one day of work. The work must be protected from wind and moist cured until the patch is sufficiently cured and has gained strength to 3000 psi minimum. The 28 day strength of the grout must be 4000 psi minimum. 7. After the patching has cured the entire cleaned surfaces of the concrete structure must be coated with an elastomeric coating waterproof membrane. This will mitigate the corrosion of the reinforcing and resulting cracking and spalling of the concrete by sealing out the moist salty air. The surface coating should be inspected periodically and repaired as required to maintain the integrity of the seal. CAGlEY. CONn & ":UMPER Structural Engineers 3949 Bralton Houston.

We recommend that you contact Epoxy Design Systems at (713) 461-8733. They are currently doing similar repairs to a pier at Todd Ship Yards in Galveston. This would give you the opportunity to see this type of repair work in process. Very truly, CAGLEY CONTI & JUMPER ~~/-$~... 8i1\ S. Jumper ~E~ - .,.---..- 98167 .-' CAGlEY.
