Interviews with each of these firms were conducted Tuesday after-
noon, February 17. It became apparent during the interviews
that the City does not have a sufficient budget to do the job.
Two firms estimated that covering the courtyard area would cost
between a million and one-half and two million dollars. The
other firms were all in the vicinity of a million dollars.
There are three basic types of enclosure that were considered.
roof. It was the consensus of the con -
One, a conventional typesultants that a conventional roof would require its own separate
support system; that is to say that the conventional roof could
not be supported from the berm walls or from the existing Audi-
torium walls and because Dinner Key is filled land the entire
structure probably would require a pile foundation.
The air -supported type roof, or the tension type roof, could uti-
lize the existing berm walls as part of the system. Where this
type roof would join the Auditorium would require supplemental
support.

One of the factors involved in the high cost is the fact that
the existing flooring is asphalt. Asphalt is flammable and
not allowed under the Building Code in an enclosed structure.
as= No one present was aware of any covering that could be applied
to overcome this problem. It was the general consensus that
the asphalt would have to be removed and a new floor installed.
Another factor was drainage. It was felt that a new roof would
— have to have a positive drainage system. To allow the water
from a permanent roof to dump either into the berm or onto the
adjacent roof would not be acceptable.
There are other technical roblems which would have to be re-
solved as part of the des gin. These problems are highlighted to
indicate why the cost will be in excess of a million dollars.
The present budget is $348,000. The Committee felt that the Com-
mission should be presented with this information before a de-
cision is reached to hire a consultant. Unless the City is
willing to provide additional funds, the ability to provide a
roof is :Hoot.
During the Commission meeting the Commission also requested that
the roof be completed by September 1. When this question was put
1 to each of the possible consultants, their basic answer was that
if you give us a contract today we could accomplish it; however,
no one would guarantee that statement.
The first shows in the Auditorium that require the roof are sched-
uled in October and November. Another critical date is March of
1982 when the Lnternational Trade Fair will be in this facility.
Should the Commission elect to provide the additional funds a
more practical schedule would be to select the architect, request
that he investir,ate the three alternative types of roof,(i.e.,
conventional, tension and air supported),analyse the cost, make
sure the roof structure meets the requirements of the potential
users, receive bids, award a contract in advance of December 1,
1981, so that necessary materials could be ordered and delivered
to Miami, with the idea that construction would start on December 1
and be through before the end of. February, 1982. It is suggested
that this be scheduled as a discussion item for the City Commission
at the meeting of February 26.
