SUBJECT: Pre-Design Cost Estimate for Public Works Expansion Project 99-1
In response to my recent request, Amcon Corporation has provided more detailed
information with regards to their pre-design cost estimate dated June 1, 1999, for
the proposed Chanhassen Public Works Facility Expansion Project.
The first item requested of Amcon was to break out the individual cost per square
foot ratios for the three primary areas: the West side building addition, which is
primarily comprised of vehicle, equipment and material storage space; the East
side building addition, which is comprised of the repair area and supporting parts
storage; and the existing building renovation area, which is comprised primarily
of the administrative and support space of the building. You may recall from the
cost estimate dated 6/1/99, that the total estimated hard cost of approximately 1.6
million dollars equated to an overall per square foot cost of nearly $65. The
attached Construction Cost Breakdown, dated 6/30/99, provides the detailed cost
information with regards to the three primary building construction spaces as well
as segregating some external costs in the columns entitled Misc. Items and
General.
The cost per square foot based on the hard cost for the West Addition, which
consists primarily of vehicle, equipment and material storage, amounts to
approximately $34 per square foot. The East Addition, which is primarily
comprised of the repair area and associated part storage equates to a cost of
approximately$56 per square foot. This higher ratio is expected due to
specialized equipment such as vehicle lift systems, etc. which are needed to be
incorporated into the two new repair stalls. The cost to renovate the existing
building area, which is comprised primarily of the administrative and employee
support space, is approximately$15 per square foot. From review of the per
square foot cost ratios, it is clear that all three are below the overall hard cost per
square foot ratio of$65 identified previously in the 6/1/99 cost estimate. The
explanation for this is rather straight forward.

The previously identified overall hard cost ratio of approximately $65 per square foot included
items which are now identified under the Misc. Items and General columns of the 6/30/99
Construction Cost Breakdown. These are additional work items or external elements not
typically included in the basic construction expansion elements, therefore, they have been
separated out. I will provide a more detailed explanation of these items later in this report. The
other major factor which comes into play to inflate the total hard cost per square foot ratio is the
renovation cost column, which totals nearly $300,000. This cost was included in the original
overall cost estimate, however, this effort in itself does not add any additional square footage to
the existing or proposed building area. Therefore, this too, has inappropriately inflated the actual
cost ratios for the proposed new space areas. Therefore, the per square foot cost ratio for both
the West Addition and the East Addition columns more accurately represents the estimated cost
for the increase in building space associated with these areas and is not inappropriately inflated by
the renovation cost which adds no additional square foot to the building nor the Misc. Items and
General Cost Items which are also not directly associated with the hard cost to construct the
additional space.
At this point it is probably due time to explain the items listed under the Misc. Items and General
columns. Under the Misc. Items column the first cost item listed is identified as "Metals" totaling
$45,626. This is the cost to provide the optional roof overhang on the south exterior wall of the
existing building. The next line item identified as "Roofing, Insulation, Caulking" in the amount
of$1 12,673 includes the $95,000 cost estimate to re-roof the existing building area, as was
discussed at a previous worksession, and an additional $17,000 option, as previously discussed, to
replace the front mansard area of the administrative section of the building. The $6,300 item
listed on the line "Glass Glazing Mirrors" is the estimated cost to replace the existing windows in
the front of the administrative area with non-opening energy efficient windows. Again, these
items are considered as external or additional elements, and are not part of the true cost to create
additional building square foot area.
There are two items listed under the General column of the construction cost breakdown. The
first line item is entitled "General Conditions" in the amount of$120,525. Amcon has also
provided an additional cost breakout detailing the items included in this line item estimate (see
attachment). The majority of the costs included in this line item are related to expenses associated
with having a construction management firm provide the on-site fulltime supervision of the
construction and also the support equipment associated with operating a field office. If a
construction manager is not used, the general contractor will be required to provide this
equipment and will incorporate the cost in his bid. It should be noted that the $18,000 cost listed
for the building permit and the $8,000 cost for the feasibility study can actually be eliminated from
the $120,525 total, since the City will not charge itself for the building permit, and the feasibility
study listed is actually the pre-design study which has been completed by Amcon and already paid
for. In effect, the General Conditions line item could actually be reduced by $26,000.
The other line item under the Genera] column was listed as "Miscellaneous." Basically, this line
item is a contingency for the architectural and engineering design phase and is intended to account
