Activities Observed:
1. Structural and Waterproofing Repairs
Kimley -Horn conducted a site visit to observe structural and waterproofing repairs on the Best Western
Hotel – Balcony Restoration project . Upon arriving on site, progress work was observed on the South
building. The following observations were noted:
a. Shoring shall be installed in all areas where repair work is taking place following the approved
shoring shop drawings. Some balcony areas on the SE block had not been shored at the time
of the visit. Kimley -Horn requested the contractor to stop the repair work in these areas
immediately until shoring posts have been properly installed. Contractor installed additional
shoring in some areas and the remaining areas will be check ed by Kimley-Horn during the
next site visit . (Reference Photos 1 & 2)
b. Progress was observed on the spall areas where delaminated concrete had been removed
and concrete edges sawcut at 90 degrees. Concrete removal and surface preparation were
observed to be in accordance with the restoration plans and technical specification in most
locations, with the exception of some areas, keeping concrete removal configurations with
rectangular shapes and square corners. Edges that are damaged shall receive a second
sawcut beyond the damaged area and the section of concrete between the original sawc ut
and the second sawcut shall be removed. Locations with lack of concrete removal around
reinforcement were id entified by Kimley-Horn and marked by the contractor in the field.
Concrete around the reinforcement shall be removed to provide a minimum clearance of ¾”
around the entire perimeter of each bar. Reinforcement shall be cleaned and reviewed by
Kimley -Horn before applying bonding agents and patching material. Contractor shall notify
Kimley -Horn where significant amount of material has been lost due to corrosion. Kimley -Horn
will check pending areas on the next site visit to verify compliance with the drawings.
(Reference Photos 3 & 4)
c. Structural identified an overhead area with concrete honeycombing at the center stair slab of
the SE block. Also, it was noticed that partial -depth repairs are being performed on the surface
above. Kimley -Horn recommended a full-depth type of repair along the honeycombing area.
d. Kimley -Horn observed reinforcement slightly damaged by saw cutting the slab with loss of
cross -sectional area in multiple locations. Contractor shall notify Kimley-Horn where significant
cross -sectional area has been lost . Where section loss of reinforcing bars is more than 20% of
the cross -sectional area, splice replacement bars to existing bars as directed by Kimley-Horn.
Remove additional concrete as necessary to provide at least a 0.75 in clearance beyond
existing and replacement or supplemental bars. Sawcuts depth shall not be greater than the
depth of concrete cover to avoid cutting of the existing reinforcing steel. (Reference Photos 5-

e. Corroded or damaged electrical conduits were observed and shall be repaired/replaced before
applying the patching material. Damaged conduits are being repaired/replaced by an
electrician hired by Best Western. Kimley-Horn requested Structural to provide a letter from
the electrician taking all the responsibilities for the repair/replace procedure performed on the
damaged electrical conduits. It’s not the responsibility of Kimley-Horn to inspect nor approve
any electrical work performed in this project. (Reference Photos 7 & 8)
f. Post pocket repairs were in progress. Kimley-Horn requested in some areas to level the repair
epoxy material with the existing floor to avoid potential water ponding around railing posts.
Excess of epoxy and aggregate shall be grinded. Additionally, all deteriorated or damaged
concrete must be removed from the repair area to provide sound concrete for bonding of the
repair material. Remove any weakened or microfractured surfaces resulting from the initial
concrete removal. (Reference Photos 9 & 10)
g. Existing railing metal connections were damaged in two locations. Kimley-Horn recommended
to connect railing members using met al angles and self -drilling screws . (Reference Photos 11
& 12)
h. Floor crack repairs were in progress. Most of the crack repairs in the east block were found
acceptable except in some locations where Kimley-Horn found that the gravity feeding epoxy
material was not leveled with the floor after surface was grinded. Contractor marked the
locations and Kimley -Horn will review the infill and pending crack repairs during the next site
visit. (Reference Photos 13 & 14)
