BACKGROUND During the process of completing the, construction of the third floor, serious defects were discovered in the main structural beams and roof system above the City Council Chambers. Further examination revealed significant deficiencies in the capacity of the structure to support its required loading. As a result, numerous meetings were held between staff and consultants, who are already assigned to services in support of the third floor project, to determine the magnitude of the problem and to explore several options to resolve it. Due to the large number of defects uncovered, consultants and staff were reluctant to recommend any solution other than the complete removal of the defective structural elements and replacement with a new light-weight structural steel roof system. Although this solution is complex to design and to actually perform, it will provide the soundest structure and assure the overall integrity of the entire structure when completed. Throughout the evaluation period, consultants and staff have stressed safety as their rn imary concern in correcting the structural defects and in the finished DATE REFERENCE SUBJECT AWARD OF CONTRACT - EMERGENCY PAGE NUMBER REPAIRS TO CITY HALL ROOF STRUCTURE 2 2 7-14-87 C-10410 ar building, as well as the safety of employees and citizens whose business re- quires them to come to City Hall. The demolition process is of paramount concern, as the main structural beams measuring 84 feet in length and about 7,000 square feet of roof must be cut into smaller sections for removal. Each of these sections will weigh approximately 21,000 pounds, and, should one accidentally fall during demolition., considerable damage could affect both the work in progress and the floors below. We have therefore begun reshoring of the roof structure at the north end of the floor. At least initially, demolition work will only be permitted when City Hall is closed, between 6.00 P.M. and 6 00 A.M. City employees and the general public will be prohibited from using the entire north end of the City Hall under the construction area during these construction hours. Further, the security guard station and after-hours entrance to City Hall has been moved to the southwest entrance of the building until the work is complete. Because of the emergency nature of this work, consultants and staff have been working closely with contractors and industry representatives to determine the safest and most effective manner in which to remove the defective beams and roof. Staff is recommending that the City enter into an emergency contract with Bob McCasl in Anchor Co. to provide the complete demol i`tion and reconstruction of the affected beams and roof structure. The work includes the fabrication of a temporary weather shed which will protect the north end of the building from inclement weather once the work begins and the roof has been removed. Bob McCaslin Anchor Co, has proposed to perform the work described herein as a general contractor for a cost of $1,518,860, including $50,000 for con- tingencies, for any necessary change orders in the event that further problems are encountered during the removal and replacement of the beams and roof. In addition to the the cost of the general contractor, the following costs are known to be necessary at this time to correct the main structural beams, roof and related damages Architect and engineer's fee $104,540.00 Construction manager's fee $105,000.00 Inspection services $ 60,000.00 Materials testing laboratory fee $ 25,000.00 The overall total for the emergency work to remove and replace the main structural beams and roof is estimated to be $1,813,400. In view of the conditions that the work must be performed under and the hours of operation, seven d ays per week, staff considers the prices proposed by all prospective participants in this endeavor to be fair and reasonable. FINANCING A s-up~ental appropriation in the amount of $1,814,000 will be necessary to fund this project. A transfer to the Municipal Service Improvements Fund 33, Project 004102, Emergency Structural Repairs will then be necessary. The General Fund Unreserved, Undesignated Fund Balance will be $21,784,591 after this supplemental appropriation. APPS®V~D ~~ DAI d N ~~~~ ° oa .
