Winter 2015
Flying High
Salt Lake City International Airport, Utah

The $1.8 billion terminal redevelopment of the airport in Salt Lake City will require over 7,000 stone columns ranging in depth from 30 to 45 feet. The stone columns are intended to mitigate static and seismic settlements beneath the new terminal and south concourse. Malcolm's design-build work is expected to begin in March 2016 and will require more than 400 shifts to complete. Up to four bottom feed stone column units will have to work concurrently to satisfy the accelerated schedule for the work.

Additional shoring and dewatering work includes over 95,000 SF of soldier pile and lagging and 20,000 SF of triple auger soil mix shoring for the proposed 2,500 feet long cut and cover utility/baggage handling tunnel. The shoring will include extensive dewatering and depressurization systems to combat the anticipated artesian pressures and shallow groundwater table.

A project of this magnitude will further solidify the presence of Malcolm's Ground Improvement Division within the Great Basin.

Trenching Along II
Alameda Corridor East, San Gabriel, California
The San Gabriel Trench Project is a 2.2 mile grade separation project that will lower a 1.4 mile section of railroad track into a 35 foot deep open trench that will run through the City of San Gabriel. The project also runs along the historic San Gabriel Mission, a historic landmark dating back to 1771 and often referred as the "Godmother of the Pueblo of Los Angeles". Upon completion of the project, traffic congestion, possible train collisions and train horn noise will be eliminated. We have been working on this trench since 2014 and have already installed 86% of the 7,407 piles and 62% of the 2,639 permanent tiebacks. The project is finally becoming a trench with the start of excavation, where over 400,000 sf of secant pile wall will be exposed.

Cut Accross
Cathedral Hill Pedestrian Tunnel, San Francisco, California

Malcolm recently finished construction on a design-build pedestrian tunnel connecting the new Cathedral Hill Hospital and medical office building. The tunnel is 25-ft. below San Francisco's Van Ness Avenue; one of the city's busiest thoroughfares and a main North-South route connecting the city to the Golden Gate Bridge. The design required the installation of shoring piles and pre-cast road deck panels during a series of weekend road closures, allowing mining and tunnel construction to be performed on a regular work schedule beneath active traffic lanes. Malcolm's Hayward office completed excavation of the tunnel and removed over 1,600 cubic yards of sand through a sidewalk opening. A custom ventilation system was developed for the project and maintained throughout construction of the cast-in-place tunnel. Detailed planning and efficient execution resulted in early completion of all closures, with streets re-opening ahead of schedule.

Good Vibe
IKEA, Renton, Washington


The existing IKEA store in Renton is currently under a full redevelopment and upgrade. The 15 acre site which IKEA has occupied was repurposed from pre-existing structures purchased from Boeing several years ago. The current project will see demolition of a parking garage to build a new 300,000 sf retail store while the directly adjacent IKEA store remains open. The building site sits upon soft alluvial deposits which require improvements in order to support the new building and mitigate seismic liquefaction. Malcolm's design-build efforts included over 3,750 each 3 feet in diameter stone columns to an average depth of 25 feet. Two equipment units will work double shift in order to complete this work within a 10 week timeframe. The ground improvement work is expected to be complete before the end of this holiday season.

New Family Member

Philip Paolelli joined Malcolm in our new Milwaukee office earlier this year. He will help the Malcolm team to expand its growing presence in the Mid-West region. Phil brings nearly 10 years of experience in specialty foundations to the Malcolm Team. He was born and raised on Chicago's South side and graduated from Purdue University. He started his work life with Aldridge Electric and moved to Long Foundation Drilling as project manager in the Southeast, where he experienced the challenges of large diameter drilled shafts in hard rock. He is also heavily involved with Carolina's local ADSC chapter. Now back in the Milwaukee area with his fiancée Samantha, he is excited to be a part of the growth and expansion in the Mid-West.
