E. Wylie Construction Company in the amount of $2,468,000 to construct the Town Centre Parking Structure. Work began in April 1983. As a result of the bond issue to underwrite the construction, the City Council took over the responsibility to oversee the parking structure construction and subsequent use. Now the structure is estimated at 90% complete and there are several changes that are determined necessary to the ultimate goal of a well- structured facility. RECOMMENDATION: That the Council approve the attached resolution approving Change Orders 26, 28, 30, 31, 33, 35 and 36 in the amount of $27,314. BOARDS/COMMISSIONS RECOMMENDATION: Not applicable. DISCUSSION: Change Order No. 26 The architect completed his plans prior to finalization of the easterly property line between Lots 4 and 7. Consequently, the pedestrian bridge that connects the structure to the Village needed to have an additional 6 ft. length added to adequately span an area that is intended for additional parking. This work had been done to assure the structural integrity of the bridge. $2400.17. Change Order No. 28 Additional catch basins are required to ensure adequate drainage for the facility based upon recommendation of the consultant engineer. $2,160 Change Order No. 30 The consultant soils engineer has recommended the reinforcing of the ground level slab within the structure and in the service road to the east of it. Originally, the reinforcing wire mesh was not shown in the construction drawings as an unintentional omission. The large mass of concrete, which includes the ground floor level of the parking structure, service road and approaches from "F" Street and Third Avenue, will develop hairline cracks due to contraction and expansion; and without reinforcing wire mesh, the cracks will open up causing separation of the concrete and differential settlement. This should be remedied by the addition of such wire reinforcing in the service road. $11,004 Page 2, Item 6 Meeting Date 1/10/84 Change Order No. 31 Because of the recent rains and the allowable use of the service road by more than one contractor, the service road grade had been significantly altered. It is necessary to bring back the grade to the level at which the slab for the service road can be poured. $1,067 Change Order No. 33 Excavations for concrete bases for the light standards must occur to a certain minimum depth. The architect did not show a footing detail for the lighting in the landscaped area. Such excavating will cost $1,147. Change Orders No. 35 and 36 The elevator shaft on the parking structure is not enclosed. This is not an uncommon practice. It was the architect's original intent to not enclose the shaft. However, several concerns were raised by staff as to vandalism and safety of the equipment that led the architect to suggest a tempered glass enclosure that will allow the occupant of the elevator to look out towards the Village and the theatre. It should be noted that the rear wall of the elevator cab is all glass. $9,516 It should also be noted that the City is receiving credits for: Change Order No. 23 - Credit of $630 for subcontractor errors in constructing a shear wall near the west camp. Change Order No. 37 - Credit of $6,328 for the elimination of 11 bollards to be placed along the service road as proposed in the original design. By changing the rolled curb orginally called for to a typical raised 6 ft. curb, the purpose for the bollards was eliminated, and these monies were saved. The total of change orders requested to be approved is $27,314. FISCAL IMPACT: A contingency amount of $125,000 was set aside from the parking structure bond proceeds for the express purpose of funding change orders. The amount of these change orders including the current requested change orders is $97,991 , leaving a balance of $27,000 unexpended.
