Reason for the Change PCO No. 172 Railing In-fills at Anoxic Tanks PCO No. 156 required removal of 2 existing walkway bridges for the former Mechanical Aerators (of the old Aeration Tanks)which were not designated for demolition. In addition,per the original contract documents the two northern walkway bridges were designated for demolition by the Contractor. The documents made no provisions to furnish new in-fill railing sections at these four locations. The cost presented herein represents the cost to furnish and install various sections of 2 line aluminum railings at these locations at the Anoxic Tanks which were the converted Aeration Tanks. PCO No. 174 Low Flow Air Switch RFI No. 278 was presented to the Engineer requesting direction on the electrical wiring required for the low flow air switch on the Odor Control fans. Contract documents did not make provisions for this wiring. The cost presented herein represents the time and materials required to furnish conduit and wiring for the Odor Control system low flow air switch. PCO No. 175 SITYP High Pressure Switches RFI No. 275 was presented to the Engineer requesting direction on the SITYP pump manufacturers discharge high pressure switch for each pump. Contract documents did not make provisions for this conduit and wiring for the switch which was provided by the manufacturer. The cost presented herein, represents the time and material required to furnish conduit and wiring to provide a high pressure discharge alarm for each SITYP pump. PCO No. 176 Glass Replacement at Control Building The former laboratory was located on the first floor of the Control Building in the northwest corner. The upper west window elevation had contained . f i panes which did not have glass in them due to renovation work previous to this contract. Architectural drawings did not call for installation of new glass sections where pieces of plywood were currently installed. The Contractor was requested to provide a cost estimate to install four new glass sections at the west window elevation of the Control Building. PCO No. 177 Replace two Catch Basin Tops During reconstruction of an existing storm catch basin and repair of an existing 12" storm pipe at the west entrance gate,the Contractor submitted RFI No. 208 inquiring on the disposition of two existing catch basin tops west of the Administration Bldg and in the center of the entrance. The Owner directed the Contractor to replace the two existing catch basin tops. This was performed on a time and material basis and the costs are presented herein. PCO No. 178 Structural Repairs to Loading Docks Contract documents indicated to make minor structural repairs to the two concrete Loading Docks at the Headworks and Control Bldg. The Owner requested complete removal and replacement of these concrete docks. CDM Smith Structural Engineers visited the site in October and prepared a report on the condition of both docks. Their report did not warrant full replacement of the structures,however due to the time elapse between original design and construction, additional repair work and crack injection was required. The Contractor was directed to perform the additional repairs on a time and material basis. The overall total cost includes a credit for the original repair work which was included in the Contractor lump sum bid.

South Windsor Water Pollution Control Facility:Loading Docks Introduction On October 11,2011,the condition of three loading docks at the South Windsor Water Pollution Control Facility was assessed. One loading dock is located along the east side of the Headworks Building-and two loading docks are located at the Control Building, one on the east side and the other on the west side. The reinforced concrete loading dock at the Headworks Building was constructed around 1980 and is approximately 24 feet by 4 feet in plan. The concrete slab is of cantilevered construction and has a thickness of 8 inches at the face of the wall tapering to 4 inches at the edge. The two reinforced concrete loading docks at the Control Building were constructed around 1966 and are of cantilevered construction. The east loading dock is approximately 46 feet by 4 feet in plan,with a thickness of 8 inches at the face of the wall tapering to 4 inches at the edge. The west loading dock has plan dimensions of 16 feet by 3 foot-8 inches and a tapered slab thickness of 8 inches at the face of the wall to 4 inches at the edge. The loading docks were previously assessed in December 2007. Photographs from that assessment are used in this report as comparison to the present day condition. Visual observations and hammer sounding of the top and underside of the concrete slabs were the means used to determine the condition of the existing loading docks. Several photographs were taken for documentation. Observations Specific areas of deterioration were noted as follows: Headworks Building-East Loading Dock Steve Kasle 10/25/11 Page 2 Top Side of Slab: ■ There was a new 1-ft by 3-ft area of spalled concrete approximately 3-in deep along the edge of the south end of the dock. Within the spall,there were two exposed reinforcing bars with surface rust,approximately 3-ft long. There was a new 2-ft by 1-ft area of hollow sounding concrete adjacent to this spall. ■ Adjacent to the column at line 3,there was a new area of spalled concrete approximately 3-ft by 3-ft by 1 Ya-inches deep. There was an existing spall, 12-in by 8-in by 1-in deep, directly across from the column at line 3 as previously indicated in 2007. ■ Adjacent to the column at line 6,there was an area approximately 3-ft 8-in by 4-ft 6-in by 1 Y2-inches deep (maximum) of spalled,hollow sounding concrete. There was an area within this spall that had been previously repaired;however,the repair was not bonded to the underlying concrete. ■ The north-east corner of the dock had a new spalled area of loose concrete approximately 6-in by 10-in by 2-in deep. ■ There were two new cracks toward the north end of the dock approximately 3-ft apart running in the short direction. One crack was 3-ft long by%-in wide and the other crack was approximately 4-ft long by 1/8-in wide. Both cracks were continuous through the concrete slab to the underside. Under Side of Slab: ■ There were three new areas of spalled concrete,totaling approximately 7 square feet by 1-in deep,located along the east edge of the loading dock. Within these spalls,there were approximately 9 linear feet of exposed reinforcing bars with surface rust. t There were 5 new cracks (approximately 1/8-in wide)totaling approximately 10 linear feet running in the short direction of the slab span. There was a rust stain on the underside of the slab along the crack and efflorescence was visible in all cracks. Control Building-East Loading Dock Top Side of Slab: ■ There were three areas of spalled concrete totaling 4 square feet by 1-in deep located on the top slab. One of the areas, 10 inches by 8 inches in size,was a new spall which developed after the 2007 assessment. Under Side of Slab: ■ There were three new areas of spalled concrete,totaling approximately 5 square feet by 1-in deep,located along the east edge of the loading dock. Within these spalls,there were approximately 9 linear feet of exposed reinforcing bars with surface rust. ■ There was 1 new crack(approximately 1/8-in wide)totaling approximately 2 linear feet running in the long direction at the east side of the dock. There was a rust stain on the underside of the slab along the crack and efflorescence was visible in all cracks. Steve Kasle 10/25/11 Page 3 ■ The bottom flange of the channel was rusted. Control Building-West Loading Dock Top Side of Slab: ■ No deterioration on the top of the slab. Under Side of Slab: ■ There was one new area of spalled concrete approximately 6-in by 6-in by 1-in deep located 4-ft from the south end of the dock.There were 2 reinforcing bars with surface rust totaling 1 linear foot within the spall. Discussion and Recommendations Headworks Some attempt has been made to repair the loading dock since the inspection in December 2007. These have broken up and the loading dock shows signs of further deterioration. Photographs 1 and 2 were taken of the top side of the loading dock during the first inspection in 2007. The previous repairs and additional spalled concrete areas are visible.in Photographs 3, 4, and S taken in October 2011 at the same location. CDM recommends repairing the top and underside spalls and cracks as follows: 1. Remove the loose,previous repairs down to intact concrete. 2. Remove the spalled concrete as specified. 3. Where reinforcing steel is exposed within the spalled concrete,the reinforcing steel should be cleaned and incorporated into the new repair mortar as specified. 4. Repair the cracks by injecting epoxy adhesive. S. Roughen and clean the substrate concrete as specified. 6. Install new polymer modified repair mortar to restore the concrete members to their original configuration as specified. Application of the anti-skid coating indicated on the architectural drawings will prevent further ingress of moisture and salt,and should stabilize the condition of the loading dock. Control Building Observations of the top side of the East loading dock indicated only one small additional area of deteriorated concrete since the 2007 assessment. Deterioration was not noted in the 2007 assessment on the underside of the dock,however,the recent site inspection indicated a few Steve Kasle 10/25/11 Page 4 areas of spalled concrete. The concrete cracks and spalls noted on the underside of the slab should be repair as stated above. The West loading dock at the Control Building indicated one area of spalled concrete on the underside of the slab. This spall should be repaired as stated above.
