CITY OF SAN BERK .RDINO - REQUEST L )R COUNCIL ACTION STAFF REPORT Page 1 of 2 The plans for street improvements on Norton A.F.B. directed that a service line for the irrigation system be connected to an existing water main along the west side of Tippecanoe Avenue. However, during construction it was dis- covered that there was no main in this area. A service connection was made to an existing water main, in "A" Street, about 200 feet east of Tippecanoe Avenue, and a 4-inch PVC water line installed to serve the irrigation system installed by this project. Installation of the service connection was done for the negotiated price of $ 5 ,500 .00 , and the 4-inch pipeline was done on a time and materials basis, since the extent of the work was indeterminate. The total additional cost for this item of work is $11 , 832 . 25 . After the sidewalk along the east side of Tippecanoe Avenue was constructed, it was found that the elevation was about 3 feet below the elevation of the ground in the vicinity of the flagpole. A retaining wall was previously constructed by change order to support the flagpole. After the retaining wall was built, it was determined that a rail was needed to provide a warning of the differential in elevation. A hand rail was in- stalled by the Contractor on a time and materials basis. The curbs and gutters that were installed, at the southeast corner of Mill Street and Tippecanoe Avenue by the project had to be removed and replaced, in order for the street to drain properly. The new curbs and gutters were installed at a higher elevation, as required to achieve adequate drainage. The traffic signal poles and controller had previously been installed by the Contractor at the grade shown on the contract plans, which placed them below the grade of the replaced curbs and gutters. These poles and controllers were necessarily raised to match the new curbs and gutters. The Contractor performed this work on a time and materials basis. IVDA staff requested that additional signage, such as "NO PARKING" and "NO ENTRY, " be installed. The Contractor performed this extra work for a negotiated price. It was determined during construction that additional traffic signal inductive loops were needed, in order for the three signals installed by this project to operate at optimum efficiency. The Contractor performed this extra work on a time and materials basis. A buried tree stump was found to be in conflict with in- stallation of a 4-inch irrigation line, and had to be removed. Electrical service to the street lights on Del Rosa Drive, from Third Street to the security gate, was disrupted by the Contractor' s work. The plans did not direct the Contractor to restore service to these lights. IVDA requested that the Con- tractor perform the necessary work to restore service to these 11-27-95 75-0264 CITY OF SAN BERK ,RDINO - REQUEST l JR COUNCIL ACTION STAFF REPORT Page 2 of 2 lights . The recommendation was made that conduit be installed in Del Rosa Drive, from Harry Sheppard Boulevard to Third Street, in order to allow these traffic signals to be interconnected. The Contractor performed these items of work on a time and materials basis. After the public sidewalks along Tippecanoe Avenue Harry Sheppard Boulevard and Del Rosa Drive were installed, it was found that some of the on--site sidewalks, leading to adjoining buildings, were not accessible. The sections of existing sidewalk, not in conformance with the new improvements , were removed and replaced as required to provide handicap access. The Contractor performed this extra work on a time and materials basis . The total additional cost for Change Order No. 14 is $46 , 620 . 28 , which will increase the contract price from $4 , 974 , 327 . 51 to $5 , 020 , 947 . 79 . The total estimated project cost included an amount of $845 , 687 . 00 for contingencies. The total accumulative cost for Contract Change Orders No. 1 through 13 is $859 , 474 . 60 . Approval of Change Order No. 14 will increase this amount by $46 ,620 .28 to $906 , 094 . 88 . Even though the line item for contingencies has now been exceeded, the project is well within the amount approved in the grant. The Economic Development Administration will allow funds to be transferred between like items. All costs incurred for this change order will be charged to Account No. 242-362-5504-1993 . Funds to finance the addition- al cost for Change Order No. 14 will be provided from the following sources: Federal Economic Development Administration Grant - 75% Inland Valley Development Agency -- - - - - - - - - 250 140 City funds will be used to finance the cost of this extra work. 11-27-95 75-0264 Sim FEDERAL PROJECT NO. 07-49-02680 CONTRACT CHANGE ORDER CHANGE ORDER NO. 14 DATE: 11/15/95 Agreement Date: 2/7/94 NAME OF PROJECT: NORTON AIR FORCE BASE STREET IMPROVEMENTS OWNER: CITY OF SAN BERNARDINO CONTRACTOR: MATICH CORPORATION The following extra work is to be performed, as directed by the Resident Engineer, and the following changes are hereby made to the CONTRACT DOCUMENTS: (1) Hot Tap into an existing water line located on "All Street, east of Tippecanoe Avenue, and install approximately 200 lineal feet of 4-inch PVC pipe, at a total cost of $ 11,832 .25. 2) Installation of handrail on the concrete wall constructed adjacent to the sidewalk at the existing flagpole, at a total cost of $ 1,164.88. 3) Modification of the new Traffic Signal poles, pull boxes and controller at the southeast corner of Mill Street and Tippecanoe Avenue, at a total cost of $ 5,436. 12 . 4) Provide and install additional traffic signage on Tippecanoe Avenue, 1'C" Street(Harry Sheppard) and 6th Street(Del Rosa) , as directed by the Resident Engineer, at a total cost of $ 1,755.13. 5) Installation of pull boxes, traffic signal loops and wiring and connect to the existing controllers on Tippecanoe Avenue, Mill Street, and Del Rosa, as directed by the Resident Engineer, at a total cost of $ 5,605.17. 6) Removal of an existing tree stub in conflict with the installation of a 4-inch water tap at the corner of "All and Tippecanoe, re-energize the entry lights at Del Rosa and 3rd Street, and installation of conduit for traffic signalization at Del Rosa and 3rd Street, at a total cost of $ 12,268.78. 7) Perform additional concrete fill-ins throughout the project to tie into existing facilities, at a total cost of $ 8,557 .95. Page 1 ei■r 0 Federal Project No. 07-49-02680 Contract Change Order No. 14 Justification: (1) In order to provide adequate water flow for the landscaping improvements on Tippecanoe Avenue it was necessary to install a hot tap into an existing 10-inch water main and increase the irrigation line from 2 to 4-inches in size. (2) When the grading was performed on Tippecanoe Avenue, it was realized that an existing Flag Pole was at the edge and 3-feet above the elevation of the new sidewalk. A wall was placed around the flag pole, additionally, a handrail needed to be placed at the top of the wall due to the height differential between the top of wall and the sidewalk. (3) The elevation indicated on the plans for the installation of the Traffic Signal Pole and controller, located on the southeast corner of Tippecanoe Avenue and Mill Street was in error. To correct this problem the new facilities at that corner had to be raised from 6 to 8 inches. (4) The plans did not provide for adequate traffic signage on the project, after the street improvements and traffic striping was completed, a problem with the traffic signage was identified and additional signage was needed. (5) The plans did not provide for adequate traffic signal loops on the project and additional traffic signal loops were needed in order for the traffic signalization to perform properly. (6) An existing tree stub was removed so that the 4-inch hot tap could be installed on "All Street. Additionally, in order to reconnect the existing entry lighting system at the entrance on Del Rosa, the contractor needed to install additional pull boxes, conduit and wiring. (7) After the improvements were completed, the contractor had to regrade and pour additional concrete throughout the project to tie the new sidewalk into the existing improvements on the adjacent properties throughout the project.
