Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: James Goehrung, Director of Facility Services
Chuck Winn, Assistant City Manager
Anna Rosenberry, Director of Finance
SUBJECT: Change Orders for the Story Mansion Renovation
MEETING DATE: May 11, 2009
RECOMMENDATION: Authorize the City Manager to sign Change Order #9 in the amount
of $11,159.61 for the renovation of the Story Mansion. 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.

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.)
