FRO"- , BII I Doran SUBJECT San BernardIno Central LIbrary Bid Pack 114 - Sltework Change Order 12 Subject Change Order Is attached along with copIes of applIcable bulletins; the reasons for and explanations of these changes are as follows: File I RFQII . . Description This Is to compensate the contractor for the cost of Importing and placIng 534 cy of fill material required to -brIng the sIte to final grade. The unIt price of SIGley for this work was established at bid time and was Incorporated Into the contract as the amount to be paid for ell Imported material. When the sltework package was actually put out fqr bId. ell prospectIve bidders were Instructed toassum~ that the cut and fill would balance as origInally engineered and to quote a unit prIce for Imported material and a unit prIce for any exported material. This approach was taken to, evold any delay or unnecessary expense to the project that mIght arIse out of a claim for extra work due to en unbalanced condition. That the site did not actually balance Is due to several factors. the most significant of which are listed below: I. When the earthwork quantities were orglnally calCUlated, an eight Inch (8") paving section was assumed (Refer to Note 2, Sheet C-3). After actual soIl testing however. the total section was revised to seven Inches over the majority of the paved area, thus, requiring additional fill. August 7, 1985 BII I Post Page Two ' > / '. File I . RFQ 15 RFQ 16 o o o Description 2. During the reconstruction of Sixth Street, the curb elevation was raised two Inches. This required additional fill In the front lawn areas to provide the correct slope for drainage to the sidewalk. 3. During the course of construction, soil was lost to SUbsidence. ~Iearlng and demolition and other work. 4. General construction tolerances such as earth shrinkage, which are difficult to predict exactly, make earthwork quantities subject to some error. Given that the limited area of the library site would not provide an area for disposing of, or obtaining additional fill material and that no site will exactly balance for the reasons above, the unit prices were Included In the bid to provide a speedy and equitable solution to this problem. The quantity of 534 cy was computed from a truck coun-/-.} I ,. _',' verified by Ledge and Ole Hamblen. "~I Thls,ls to compensate the contractor for the cost of provIdIng concrete monuments for several dedication placques adjacent to the war memorial. the sidewalks around the placques and the foundations for the bronze canon. This Is the cost for changing the point of connection for the water service. This Is per Bulletin 12. We have revIewed these Items and the associated costs and have fou~d them to be acceptable. We, therefore. recommend approval of this change order. WFD:mm Attachment Cop les to: , .
