Previous Projects
We partner with our clients to understand their unique project requirements and help them identify the right equipment for the job. Here are just a few examples of how ROC has been able to support our clients.
UTILITY TOWERS
Client Heavy Marine Metal Ltd.
Project Heavy Marine Metal Ltd. relocated BC Hydro transmissions towers. They installed 2032mm diameter permanent cased foundation caissons.
ROC Equipment Utilized BUMA H1800B Hammer Grab, 2032mm Casing
RAILWAY CONSTRUCTION
Client Shimmick-Traylor-Granite (STG) JV
Project STG managed the drilled shaft and shoring installation for the HART airport guideway project. The team successfully drilled one shaft 350-feet deep, the deepest shaft of its kind in recorded history.
ROC Equipment Utilized BUMA Casing Rotator CR3000, BUMA 2.2 & 3.6m Crane Mount Oscillators, Power Packs, Hammer Grabs, Chisels, Casings and Tremie Pipe
ROC Technical Expertise ROC helped design a trestle that would withstand the weight and torque of the foundation drilling equipment needed to install the project’s massive oscillated shaft.
BRIDGE REPLACEMENT
Client Walsh Construction
Project Walsh Construction replaced the Kennedy Mill Bridge in Kentucky. The new 826-foot-long bridge required unique engineering and constructability methods due to the 200-foot depth and behaviors of the lake.
ROC Equipment Utilized BUMA Reverse Circulation Drilling Rig BM-R3030 with 104” Casing Clamp and Cutting Diameter of 96” (2440mm).
RAILROADS
Client Malcolm Drilling
Project Malcolm Drilling helped replace a century-old BNSF Railway bridge over the Sabine River in Easton, Texas.
ROC Equipment Utilized BUMA C2200T 2.2M Drill Mount Oscillator, BUMA Power Pack, BUMA 2200/1800 Reduction Inserts
FOUNDATIONS
Client Alliance Diversified Enterprises
Project Alliance Diversified utilized a drill mount oscillator to install foundation piles for a custom residence. This allowed them to dig through groundwater and limited space conditions on beach front property.
ROC Equipment Utilized BUMA 1500 Drill Mount Oscillator, BUMA Power Pack, 1500 MM Casing, BUMA Hammer Grab & Spherical Grab
TREASURE HUNTING
Client ”The Curse of Oak Island” on The History Channel
Project ROC provided the equipment and staff used to drill for treasure on The History Channel show “The Curse of Oak Island.”
ROC Equipment Utilized BUMA C1500T Oscillator, P5318C Oscillator Power Pack, H2000B Hammer Grab, S2310 Spherical Grab, 2500mm Casing
WATER SYSTEMS
Client Southland/Mole Joint Ventures & ATS Drilling
Project Installed 3000mm permanent casing up to 500ft deep for the Kaneohe-Kailua Sewer Tunnel. The gravity conveyance tunnel was designed to increase the reliability and capacity of the community’s sewer system and provide temporary wastewater storage capacity to help prevent sewage overflows and spills, in particular during heavy rainstorm events.
ROC Equipment Utilized BUMA C3000G Casing Oscillator, BUMA P5318C Power Pack
SLOPE STABILIZATION
Owner Sound Transit
Project As part of the Federal Way Link Extension Project in Kent, WA. ROC’s equipment was utilized to place shafts for slope stabilization. Stabilization efforts were designed to address a liquifiable layer of soil that had been identified fairly deep below the light rail alignment.
ROC Equipment Utilized BUMA C3600G Casing Oscillator, BUMA P6128V Power Pack, 3600mm OD Segmental Casing, BUMA 3300 Spherical Grab
FOUNDATION REPAIR
Client Legacy Foundations
Project Foundation mitigation repair of the 301 Millennium Towers building located in downtown San Francisco. Legacy installed 52 perimeter piles, each 24 inches diameter by 300 feet deep, around the building to prevent the building from sinking further.
ROC Equipment Utilized BUMA C1300T Casing Oscillator, BUMA C1000T Casing Oscillator, BUMA P3818V Power Pack, 914mm OD Segmental Casing, BUMA HRC914 Casing Clamp, 610mm OD Segmental Casing, BUMA HRC610 Casing Clamp
LAX People Mover
The Automated People Mover (APM) at Los Angeles Airport (LAX) is a 2.25-mile elevated guideway train that delivers passengers between LAX and new offsite parking, car rental, and transit facilities. Legacy Foundations was selected as the driller for the railway’s foundation piles.
To mitigate dust, vibration and sound impacts during construction, Legacy used the oscillator method for large diameter Cast-In-Drilled-Hole (CIDH) pile construction. There were five oscillators on the project at one time ranging in size from 1300mm- 3352mm. The team installed 265 piles along the APM route, the largest CIDH piles measuring up to 11 feet wide and the deepest measuring 99 feet down.
