RUNWAY MAINTENANCE
AUTHOR Walker Jaroch
A New Approach
to Runway Repair
THE SAN Luis Obispo County Regional Airport (SBP)
completed its Runway 11-29 Rehabilitation Project in
October 2021. It's the first significant rehabilitation of
the runway since 1997, although it had been extended
twice - most recently in 2007.
" The joint separations, we had a lot of
longitudinal cracking going on in sections.
And really, a large portion of the
runway had not received much attention
for quite some time, " said Craig Piper,
deputy director, Department of Airports,
County of San Luis Obispo.
" The driving factor on it was that the
runway was showing significant signs
of deterioration due to the age of the
asphalt surface. We determined the
runway was structurally fine, it was just
that the surface was starting to deteriorate, "
added Scott Van Gompel, department
manager, aviation, Mead & Hunt.
At the same time, the runway lighting
was found to be beyond its useful
lifespan and the spacing no longer compliant
to FAA standards.
" The project included the full replacement
of that existing infrastructure, as
well as a mill and overlay of the surface
of the runway to get a new surface on
top, " said Van Gompel.
What made the project unique was
its use of Construction Manager at Risk
(CMAR), a move not often taken with
projects of this nature.
" We start working as a contractor
with a designer in the airport. In this
case, at the 60% plan level, we were
brought in to start analyzing plans and
specs and value engineering type work
and cost analysis, " described Adam
Souza, construction manager, Granite
Construction.
" Then when it comes down to the
100% plan phase, we put together a price,

a GMP price, which is called guaranteed
maximum price. We sat down with the
owner and the engineer and reviewed
it and agreed upon that it was fair. And
we were awarded the contract to do the
construction phase. Whereas a traditional
project, a bid-build project, plans are
put out. You have plus or minus 30 days
to put together a price, and you turn it
in. At that point, the contractor has no
input in how to make the project better
at that point, " Souza continued.
Piper said it is the county's first
CMAR project.
" I believe it's the first one that has
been done at least in California, under
AIP grant, " Piper added.
Phased for Success
CMAR was crucial to the success of
the project, especially when it came to
phasing the work and minimizing the
construction's impacts to the airlines'
and airport's operations.
" We have a single runway that the
air carriers use. The phasing and the
