Authorize the City Manager to sign Change Order #10, for a credit of ($4,803.40). Authorize the City Manager to sign Change Order #11, for a credit of ($333.36). BACKGROUND: Work is still progressing and on schedule for the renovation of the Story Mansion. Interior finishes are being applied. Plaster is complete in the entry foyer, office, dining room, and library. Painting has started. The floors are sanded and ready for finish. The ceiling areas on the porch are completed. The mechanical equipment is being installed. Doors and wood trim finishes are underway in some parts of the building. The new additional is framed and sheathed and the roof is installed. Work will start in the next week on site improvements. Change Order #9 includes 7 items: Proposal Request #007 is for material changes to the kitchen prep area. The materials in this area were similar to the solid wall board in the exit corridor outside the kitchen, Rooms 114 and 116. The materials would not accept sheet rock due to uneven conditions once the solid board was removed, (too much glue used to attach the plastic wall board). Once the wall was stripped the owner directed that insulation be installed in the walls, (none was in the wall cavity). The change in the sheet rock will require some modifications to the window and door trim. Final figure after negotiation and clarification is $4,691.98. Proposal Request #08, (Change Order #8), is a revision to the last change order that was presented for approval. It was pointed out to the dry wall finishers that consideration was not given for work that would have already had to be done prior to the specified change. The result is a credit of ($1,780.80) for work in Servery 113. 6 Proposal Request #09 is an owner requested item. The second floor deck on the east side of the building is a solid floor. Since the exterior renovations were done to the building two years ago, drainage from the porch deck caused the paint to peel from one of the entry columns on the main floor porch. Ice build-up on the deck and a frozen drain pipe caused the water to drip down the column. Staff will need to shovel accumulated snow off the deck as a maintenance practice. This change order will install electrical outlets for a heat tape circuit that will keep the gutter from freezing and control the run-off. Cost for this change is $1,140.98. Proposal Request #10 addresses the tie in from the new addition and the existing foundation wall of the building. Upon excavation it was found that the stone wall near the handicapped ramp was not structural. A foundation area had to be added and new supports installed for the ADA handrail on the west side entrance ramp. Total change $4,158.11. Proposal Request #13A is for hardware in the Library. Some of the drawer pull hardware for the cabinets in the library was missing. The proposed hardware in the original bid submittal was considered and rejected because it was not a good match. The missing covers will be custom manufactured to match what is still attached, $210.00. The second part of this is owner initiated. There have been requests for the last few years for holiday lighting on the building. Two electrical outlets were added in the porch ceiling to accommodate Christmas lighting on the building, $766.40. Total change is $1,034.98. Proposal Request #14 is for the cost of 4 additional sprinkler heads in the Port-Cochere near the north entrance to the building. Four heads were originally shown on the drawings to cover this area. When the ceiling area was opened to install the heads, it was determined that the construction methods used in this roof area would require additional heads. These heads would be installed on top of the four shown in the drawings, pointed up to cover the combustible materials in the roof Cost for the head is $408.31. Proposal Request #16 is an owner requested change for door hardware. After reviewing the door schedule with the Parks Department changes were made to the type of locks used so that areas of the building could be closed off. This will allow some areas of the building to be rented out, according to the proposed fee schedule and keep other parts of the building locked off. These changes amounted to $1,506.05 Change Order #10 is a credit for a change to the type of windows that will be installed in the solarium on the west side of the building. The windows were originally identified in the bid documents were specified as a commercial metal window assembly. At the direction of the Historic Preservation overview people windows will be installed in wood. The change will result in a credit of ($4,803.40). Change Order #11 is for three items. There were architectural changes to some of the light fixtures that resulted in credit of ($1,542.00). The light fixture on the main stair was previously fed by an exposed conduit that was hidden under a dropped grid ceiling. Because the ceiling was scheduled to be removed, the electrical feed for the lighting fixtures was re-directed above the finished ceiling and a new service was provided for the light an increase of $774.00. The new addition that was added to accommodate the handicapped accessible restroom was framed as 7 new construction. The tie in with the original building exaggerated the fact that the building was out of plumb. In order to match the new and the old elements, some additional trim work was added to visually tie the two rooms together, $279.84. The result of these three changes is a credit of ($333.36). ASBESTOS: In 2003, the Mansion was tested for asbestos in preparation for any future work that might be considered. At that time our contractor determined the presence of asbestos under the flooring in the dining room area but found no other indications asbestos was present in other areas. In April 2009, and as a part of the regular construction process, workers unknowingly exposed asbestos insulation during the removal of plywood from the porch ceiling. This asbestos insulation fell out of the ceiling area onto the floor inside and outside of the building and resulted in additional asbestos remediation on the first, second and third floors. Additional clean up and testing costs for this remediation work are $34,665.23 and will be charged to the project contingency as indicated below. We have met with the asbestos cleanup contractor and testing contractor to voice our dissatisfaction with some of their service and have asked for price reductions from their original invoices. We have not yet paid all of the their invoices as those discussions are ongoing. FISCAL EFFECTS: These three changes will be charged to the project contingency. The contingency for the project began at $83,210 and has $4,700 remaining. The following table lists the change orders and other project elements that will be charged to the contingency. It includes work that we have had completed that is not a part of the construction contract, professional services (testing/inspection), and adjustments to original work bid for landscaping (future change order #12.)
