ITEM TITLE: Resolution /4 °2 f Approving Change Order 41 for the Town
Centre Parking Structure
. A,
SUBMITTED BY: Director of Building & Housi t %�� 5ths Vote: Yes No X )
REVIEWED BY: City Manager,
On December 21 , 1982, the Redevelopment Agency awarded a contract to C. E.
Wylie Construction Company in the amount of $2,468,000 to construct the Town
Centre Parking Structure. Work began in April 1983. As a result of the bond
issue to underwrite the construction, the City Council took over the
responsibility to oversee the parking structure construction and subsequent
use. The structure is estimated at 96% complete.
RECOMMENDATION: That the Council adopt the attached resolution approving
Change Order 41 in the amount of $6,196.
BOARDS/COMMISSIONS RECOMMENDATION: Not applicable.
DISCUSSION:
In a typical construction using brick as a facing to concrete block, it is up
to the owner to decide if the brick should have a constant new appearance or a
used brick look. A constant new appearance is accomplished by sealing the
brick with a waterproof sealant immediately after a light sandblasting to
clean off mortar remnants, discolorations and other consequences of
installation. On the other hand, if the brick were left untreated after the
light sandblast cleaning, the brick surface would eventually show lime
deposits from the mortar that leak through the porous brick material . This
"whitening" or efflorescence gives brick that used look that is sometimes
highly valued for its appearance, especially on older buildings.
Staff's opinion is that the structure has a crisp, contemporary look to it.
The brick facing was applied in such a manner as to enhance that crisp look.
Therefore, staff recommends that the brick would show best if the color were
kept uniform and not appear to age. That is, the whitening effect on the
brick would tend to blend in with the light gray color of the concrete portion
of the structure; thus losing line and form of the brick accent especially
when viewed at a distance. By applying the sealant, the color will be left on
the brick for approximately 10 years before another coat of sealant must be
applied.
