Phase The Work
When full repair is unaffordable, prioritize by safety.

hile large is a relative term,
sometimes a concrete repair job
is financially too large for an owner
to undertake in one bite. And yet
rather than performing the repairs in
manageable, more economical pieces
over an extended period of time, the
repairs are too often put off until the
situation becomes intolerable, as well
as much more expensive.
RCM Construction Corporation
often suggests to owners that the
repair of delaminating and spalling
concrete be performed in phases.
Here are two such projects:
Project 1
RCM recently completed Phase I
of lanai repairs on a three-story
apartment building. Owned by a
family whose father had built the
building 43 years ago, no concrete
repairs had previously been done. Due
to Hawaii’s salt-laden environment, the
roof edge and the 10 concrete lanai in
five vertical stacks were in bad shape
with rusting rebar. Pieces of concrete
had fallen from the edges. While the
extent of repairs at individual lanai
varied, some lanai required 75 percent
of their surface area to be completely
removed by pneumatic chipping tools
and replaced.
After providing a ballpark figure
for the repair, we were immediately
informed by the client that such
funds were unavailable. With some
encouragement, the owner told us
that they were financially capable of
paying for four or five lanai repairs.
We discussed various options aimed
to maximize the owner’s return. It was
agreed that for Phase I we’d perform
repairs on the lanai that were in the
worst condition with cracked and fallen
concrete, namely the third and fourth
vertical stacks and roof edges. Upon
completion the owner would start saving
for Phase II repairs that would include
the remaining lanai and roof edge.
A life-safety condition at these
locations would have existed for several
more years had the owner not take this
approach. Phase II is forthcoming.

Project 2
A second project involved a
much larger, 40-year-old, four-story
concrete and concrete block building
in Makiki. The concrete lanai, corridor
and concrete block walls were
evidencing spalling. The owner had
insufficient funds to undertake all
of the repairs. Again, we suggested
using an affordable, two-phase
approach, giving the family a few
years to recoup for the Phase II work.
Although both the front and rear
of the building required extensive
repairs, the space under the rear
lanai was rarely used. Because the
front of the building presented the
greatest chance of falling concrete
actually hitting a person or vehicle,
we suggested that Phase I address the
front and Phase II could take care of
the rear of the building.
Both Phase I and Phase II have
been successfully completed.
