  • Deep Foundation Solutions, PresidentPresident and Founder of Deep Foundation Solutions. We are consulting engineers with expertise in the construction of deep foundation systems. These systems include drilled shafts, secant piles, micropiles, tiebacks, soldier pile and lagging, and soil nails. We offer pre-construction services, including estimates, feasibility studies, and value engineering. We help mitigate excessive cost and quality issues during construction. We assist with the most cost-effective choice of equipment to use and the best method to install the specified deep foundation system with minimal quality control issues. If disputes arise between subcontractors, general contractors, engineers, or owners we help resolve the issue before litigation is necessary. We provide expert witness services if litigation is required.
  • Becho Inc., President
    Management of a Deep Foundation Contractor, with an annual budget of approximately $30 Million in revenue. Responsible for estimating and managing a wide variety of geotechnical projects. Responsibilities include interaction with the general contractor, owner representatives, and engineers. This would include submittals, QC programs, scheduling, and resolving issues that developed on the project. Managing project cost and meeting budget constraints while still meeting all quality requirements and schedule milestones. Projects include Drilled Shafts, Secant Piles, Micropiles, Earth Retention, Tiebacks, Soldier Piles, Soil Nails, and Slope Stabilization.

Notable Projects

• PL3 - Tunnels, Los Angeles, CA - $4,400,000Furnish and install 100 secant piles and 20 tangent piles to provide a watertight access shaft 100-ft in diameter for 2 Tunnel Boring Machines (TBM) to start the Phase 3 and 4 tunnels. The secant piles and tangent piles were 4-ft diameter and 85-ft deep. The reinforcing bars used across the tunnel openings were glass reinforced fiber (GRFP).
• Henry Hudson Parkway, Bronx, NY - $18,600,000Furnish and install 160 battered micropiles with a design load of 1200 KIPS and 168 vertical micropiles with a design load of 250 KIPS. The micropiles were drilled through about 70 feet of existing reinforced concrete with a rock socket of about 20 feet. The micropiles were constructed with 13.375-inch casing, 2 #28 Grade 75 KSI reinforcing bars, and 6000 PSI grout. The piles were installed off limited access platforms with less than 18 feet of overhead clearance. A portion of the work was done from a 20 feet wide platform suspended over the Harlem River. The alignment for the piles was very critical, with less than 4 inches of deviation allowed in 50 feet.
• East Side Access, CH061A, Queens, NY - $3,200,000Furnish and install 66 secant piles, 3.3-foot diameter, 35-feet deep. The piles were installed under a bridge with 26 feet of overhead clearance. In order to provide 26 feet of overhead clearance the 39th Street bridge footing was underpinned to allow the excavation to proceed below the bottom of footing for Track A. The geotechnical conditions made drilling very difficult due to lose caving sand, and numerous cobles and boulders. Every other pile required a 24-inch-wide steel beam that need to be spliced.
• East Side Access, CH057, Queens, NY - $2,900,000Furnish and install 80 secant piles, 3.3-foot diameter, 40-feet deep. The piles were installed under a bridge with 26 feet of overhead clearance, and allowed for the excavation of Track D. The geotechnical conditions made drilling very difficult due to lose caving sand, numerous cobles and boulders, and groundwater in the bottom 10 feet. Every other pile required a 24-inch-wide steel beam that need to be spliced. The concrete was tremie poured in 10 feet lengths.
• City Island Bridge, Bronx, NY - $3,500,000Furnish and install 8 drilled caissons, 4-foot diameter, 40-feet to 50-feet deep. These piles were the foundations for two new bents located in the middle of the bay. The piles all had permanent casing with a rock socket in 15,000 PSI granite. These piles were also installed though the existing bridge bent foundations, creating a challenge when seating the permanent casing in rock. The piles had 42-inch rock sockets. We conducted an Osterberg load test on one of the production piles. We will also install 52 micropiles with a 13.375-inch casing and 12-inch rock socket. These piles were load tested to 606 KIPS with about 0.25 inches of total movement.
• Hudson Yard Platform, NY, NY - $42,000,000Furnish and install 250 drilled caissons, 3-foot to 5-foot diameter, 40-feet to 80-feet deep. The piles all had permanent casing with a rock socket in 15,000 PSI granite. The piles were installed in an active rail yard in Manhattan with 30 rows of tracks. The piles were located between the tracks and inside existing buildings making access issues with equipment a major obstacle. The piles supported a deck over the tracks for a 10-story retail center or up to a 100-story office tower. Approximately 20 piles were drilled 1-foot to 5-foot away from an active subway or rail tunnel. These piles were installed with a gyro and were located within an inch of the design location. We installed two test piles and did Osterberg load test to determine the capacity of the rock. The results of these test were more than triple the estimated rock capacity used in the design. The rock sockets were reduced by about a third of the length, saving millions of dollars for the project. We also installed 20 Micropiles inside a building with 17 feet of overhead clearance that had a design load of 1200 KIPS
• Hudson Yard Amtrack Tunnel, NY, NY - $14,000,000Furnish and install 630 secant piles, 3.0-foot diameter on a 2.5-ft spacing, creating a secant pile wall approximately 1,600 feet long averaging 35 feet in height with 3 rows of tiebacks. All the piles were embedded 2-foot to 5-foot into granite. The water table was about 5 feet below existing grade, so it was imperative to have a watertight system. Active rail tracks were within 15 feet of the secant pile wall. Some of the piles were installed on a 5–10-degree batter to avoid an overhead bridge.
• Atascadero City Hall, Atascadero, CA - $1,800,000Design build underpinning of a 3-story concrete structure built in 1917. The system used 200 micropiles installed in the basement with approximately 9-feet of overhead clearance. The micro piles were load tested to about 400 KIPS.
• La Plaza De Cultura, Los Angeles, CA - $2,200,000Design build underpinning of a 2-story structure built in 1870 using unreinforced masonry. The system used 250 micropiles installed in the basement with approximately 9-feet of overhead clearance. The micro piles were load tested to about 220 KIPS.
• Cranks and Telefson, Culver City, CA - $3,500,000The repair of a 100-foot high 1:1.5 slope in a densely populated hillside community. The repair was over a 10-foot diameter active sewer. This repair utilized 70-feet deep drilled piles, a 5-foot-thick reinforced concrete matt, epoxy coated steel soldier piles and wood lagging.
• Alameda Corridor, Los Angeles, CA - $14,000,000An earth retention system for a 30-foot-deep railway trench crossing approximately 5 cities in southeast Los Angeles. The earth retention system consisted of approximately 11,000 tangent piles 3-foot diameter creating walls about 44,000 feet long.
• Cold Spring Bridge, Santa Barbara, CA - $2,100,000Furnish and install 2000 KIP permanent anchors to support a steel arch bridge foundation. The anchors were 48 strands and 125 feet long.
• Seven Oaks Dam, Highlands, CA - $2,300,000Furnish and install 16 rows of anchors 8 feet apart in a vertical concrete face. The top row of anchors was about 150 feet above the existing grade below. The permanent anchors were 1000 KIP and approximately 100 feet long.
• Railroad Canyon Dam, Lake Elsinore, CA - $1,700,000Furnish and install 30 epoxy coated anchors through the concrete thrust block of an existing dam. The 1500 KIP anchors were installed by coring 11-inch diameter shafts through 80-feet of concrete and then drilling a rock socket 50 feet deep in granite.
