REPORT TO: Honorable Mayor and City Commission

SUBJECT: Change Orders for the Story Mansion Renovation
MEETING DATE: March 9, 2009
RECOMMENDATION: Authorize the City Manager to sign Change Orders numbers 3
through 7 for the renovation of the Story Mansion in the amount of $23,343.44. Change Order
#003 in the amount of $5,049; Change Order #004 in the amount of $4,168.98; Change Order
#005 in the amount of $5,542.79; Change Order #006 in the amount of $4,834.19; Change Order
#7 in the amount of $3,748.48.
BACKGROUND: Work began on the renovation of the Story Mansion on January 5, 2009.
Work is progressing well on the project with the basement and main floor demolition complete.
The basement renovation and conversion is well under way. Plumbing and electrical rough in is
30 % complete. Mechanical ducting is being installed. The addition excavation, foundation and
footing walls are installed. The fire sprinkler system installation has started in the basement and
main floor. Installation on the second and third floors has been curtailed due to the identification
of additional asbestos containing materials.
Change Order #003 is for the conversion of the 2 inch fire line to a 1 '/2 inch domestic water line.
City Code requires that the line be sized down on the outside of the building. This work will
expose the line; neck it down to the appropriate size; connect the new 1 '/z inch line into the
building and the water meter; and reclaim the lawn area. This approach was chosen because the
impact fee fora 1 %2 water line, over a 2 inch line, is $12,000.00 less. This could be a net savings
of approximately $7,000.
Change Order #004 is for the cost of replacing the wood floor that was damaged by the asbestos
abatement contractor during the removal of the flooring materials in the kitchen and dining
room. This work is being charged to the project, but the cost has already been recovered from
the abatement contactor. Safetech, the abatement contractor charged $11,250.50 for the removal
of the asbestos flooring. The cost for the flooring repair was deducted from their bill and they
were only paid $7,081.52.
Change Order #005 items include a number of code required items that are required for the
proposed assembly uses. The plan review was done concurrent with bidding the project in order
to address the tight time line for the project. The revisions include a 60 minute fire rated door;
the installation of fire blocking at a number of ceiling and wall areas; and the replacement of
two glass units in windows south wall that abut the solarium. Floor levels were raised at this
location to address Americans With Disabilities Act requirements and the raised floors put the
window height closer to floor grade requiring that the glass be changed out to tempered glass for
safety purposes.
Change Order #006 addresses framing issues that were uncovered during the demolition phase
of the project. Past modifications to the building resulted in framing and flooring members being
cut away and not braced properly. The structural engineer evaluated the framing once it was
exposed and specified the proper method of attachment. These costs are for the hangers,
fasteners, and materials needed to properly brace the structural elements of the building.
Change Order #007 is for addition material changes to the kitchen prep area. There were many
modifications to this area of the building over the years. The solid wall board material was
installed using a heavy glued up over older wall materials. Upon removal of the solid wall
material, the older wall material could not be salvaged. Covering it with another layer of sheet
rock would have required changing the window and door j ams and have resulted in a good deal
of extra mud and tape work because of the uneven surfaces. Direction was given to remove the
wall finishes down to bare studs, insulate the wall cavities, (because there was no insulation in
the walls), and re-sheet rock the walls.
FISCAL EFFECTS: These five items will be assessed against the contingency fund for the
project. The contingency for the project is $83,210. The three changes approved on February 23
were for $9,088.38. This left a balance of $74,121.62 in the contingency budget. These five
changes are for $23,343.44, leaving a contingency balance of $50,778.18.
ALTERNATIVES: As suggested by the City Commission.
