CIPP AND TUNNELING CONTRACTOR SAK CONSTRUCTION COMPLETES
CHALLENGING
$10.875 MILLION MSD LEMAY TUNNEL
SAK
Digs In to Complete Stalled Excavation Work
For
Lemay Wastewater Treatment Plant
Wet Weather Expansion Outfall Sewer Project
ST. LOUIS (June 5, 2012) – When
unexpected ground conditions put a sudden halt to initial efforts to excavate a
new 558-foot-long, 16-foot-diameter tunnel leading from the Lemay Wastewater
Treatment Plant, the Metropolitan St. Louis Sewer District reissued the project
for bid to find a contractor equipped for the challenge. The project award, which included pipe
installation as well as tunneling, then went to SAK Construction, a national
pipeline rehabilitation, CIPP
and tunneling services
contractor headquartered in O’Fallon, Mo. SAK began work in December 2010 and completed
the $10.875 million project, formally named the Lemay Wastewater Treatment
Plant Wet Weather Expansion Outfall Sewer project, in approximately 16 months. The completed outfall sewer line is now in
service, providing a new effluent discharge line from the Lemay Wastewater
Treatment Plant to a structure on the west bank of the Mississippi.
The scope of work on this project included an extensive tunnel
excavation of 381 linear feet. A tunnel boring machine excavated the tunnel to
just over 11 feet; crews then went in using non-explosive and explosive rock
methods to further widen the tunnel to a 16-foot-diameter horseshoe shape to accommodate
the installation of concrete pipe segments that were 12 feet long and 132
inches in diameter. In addition to
difficult ground conditions, challenges encountered and resolved by the SAK
team included the discovery of a previously unknown and unmarked sanitary
tunnel, which caused flooding during tunnel excavation and required the erection
of a temporary bypass pumping operation.
The project was designed by Black
& Veatch. The construction management team representing MSD on this project
was KAI Design & Build.
SAK is one of the fastest
growing, privately held pipeline rehabilitation, CIPP and tunneling contractors
in the U.S., with 300 employees working on projects in 28 states. SAK

to the full spectrum of current trenchless or “no dig” technologies, including CIPP (cured-in-place pipe) pipeline
rehabilitation for sanitary and storm sewers and Aqua-Pipe® for drinking

licensee for Aqua-Pipe in an 11-state region and a contract partner of three cooperative
purchasing organizations based in Texas. The organizations, which serve government
entities nationwide, include Choice Facility Partners and The Cooperative
Purchasing Network, both in Houston, and BuyBoard in Austin. SAK clients
include a variety of city, county and state agencies; industrial sectors; the
federal government and municipalities; and water and sewer cooperatives
coast-to-coast.
In the most recent annual ENR
(Engineering News Record) survey of national specialty contractors, SAK Construction was named to two separate
lists, ranking 7 on “The Top 20 Firms in Utility” and 214 on “The Top 600
