s <br /> URS <br /> As of Friday,January 20,2012,we have spent$214,303.31. With the current contract amount at <br /> $219,200.00 this leaves$4,896.69. Chuck Hunsinger has told me that EGM will.be submitting <br /> an invoice to URS for$4,871.69,so that will take most of the remaining budget.However BGM <br /> still has$31,083.02 remaining in their budget per their agreement with URS. <br /> According to Chuck Hunsinger,some of the remaining fee will be required to develop the <br /> electrical power scheme for the residential pumping station.BGM needs to see the electrical <br /> panel at#54 South Shores.Their budget also included fee for the bidding and construction <br /> phase.URS also included fee for the construction phase,however that budget was used to <br /> address issues that developed during the final design. <br /> The budget for many of the tasks was exceeded in December as we worked to complete the <br /> plans for a January 6, 2012 prefinal submittal.Reasons for the over-run include: <br /> 1) Scope for the final design also included work to complete Phase I,however Phase I <br /> comments had not been received when scope and budget were developed. Comments <br /> regarding 4(f) impacts and noise analysis required additional work to complete Phase I. <br /> 2) After starting the final design,we discovered that the sewer to remain in place on the <br /> west side of the bridge would interfere with proposed guardrail posts adjacent the 10' <br /> shoulders.Guardrail posts had to be relocated to miss the sewer and this resulted in a <br /> wider shoulder with more fill being placed in Lake Decatur. <br /> I <br /> 3) With the sewer now located under the shoulder on the west side of the bridge,we <br /> discovered that the sewer did not have adequate cover;since it will now be exposed to <br /> vehicular loads.The profile was adjusted to provide additional cover over the sewer <br /> pipe. <br /> 4) The adjustment to the profile resulted in the project limits being extended to the west and <br /> another property(Vancil)is now affected. <br /> 5) Manhours and fee were established assuming that the new sewer pipe on the east side of. <br /> the bridge would be buried in the roadway embankment.It was determined that this <br /> option would be difficult to construct, considering that the sewer.pipe needs to be i <br /> constructed in advance of other activities.The pipe also interfered with drainage.For <br /> these reasons, the pipe was moved to the north to be in line with the new manhole and <br /> the pipe on the proposed sewer bridge.Pipe piers were then designed so support this ' <br /> portion of the pipe.Design of the pipe piers was not in the scope. <br /> 6) The original borings were taken when there were no plans for a sewer bridge or a center <br /> pier on the roadway bridge. Although not in the scope,URS requested SKS to obtain an <br /> additional soil boring.The soil boring was taken in Lake Decatur, adjacent to the <br /> existing structure.The results were used to design the substructure units for the sewer <br /> bridge and the center pier of the roadway bridge. <br /> i <br /> 2 <br />
