Mr. Campbell has over 35 years of experience in the geotechnical/geostructural engineering profession. His advanced education includes a Master’s Degree in Geotechnical Engineering from Ohio State University. Prior to joining Burns Cooley Dennis, Inc. in 2009, he served at D’Appolonia Engineers for 23 years. Mr. Campbell is experienced in a wide variety of engineering projects including bridges, roadways, retaining walls, landslide remediation, earth dams, single and multi-story buildings, rock slopes, industrial facilities, levees, floodwalls, solid waste disposal facilities, towers and tanks. He has been responsible for all phases of geotechnical investigations and analyses.
Mr. Campbell has considerable experience in geotechnical investigations and design of various retaining wall types, ground improvement, pile systems and slope stabilization systems. His responsibilities have included: the planning and coordination of field and laboratory investigations; design of slope stabilization systems incorporating driven piles, micropiles, drilled shafts, and post-tensioned anchors; design of Deep Soil Mix (DSM) and stone column ground improvements systems to support storage tanks and other structures; and design of DSM and jet grout shear panels to provide stability to embankments founded on soft soils. Some projects on which he has worked include:
- Lost Lake Dredge Material Placement (DMP) Area. Levee Stabilization, Houston Galveston Navigational Channel, Harris and Chambers Counties, Texas. Designed Deep Soil Mixed (DSM) shear panels to allow for reconstruction of a 2000-ft length of levee surrounding a DMP area. The levee had previously experienced excessive settlements and rotational slope movements toward the shipping channel.
- LOOP Oil Storage Tanks, Cut Off, Louisiana. Design of ground improvements for three large diameter oil storage tanks constructed over very soft soils. The ground improvement consisted of 8-ft diameter deep soil mix (DSM) columns extended to an approximate depth of 70 ft. The design included a load transfer platform to distribute the tank loads to the DSM columns.
- Natchez Bluff Stabilization, Natchez, Mississippi. The project included soil nail walls, a mechanically stabilized earth wall, and beam and lagging walls with post-tensioned soil anchors to improve the stability of loess bluffs ranging in height up to 180 ft along the Mississippi River.
- Highway 80 Bridge over the Mississippi River, Vicksburg, Mississippi. Stabilization of the 110-ft tall slope below the east abutment of the Highway 80 Bridge. The design included reconfiguring the slope to remove soil accumulation against the bridge piers and a tiered soil nail wall to improve global stability.
- Ameristar Casino, Vicksburg, Mississippi. Designed three large anchored soldier pile and lagging retaining walls at the Ameristar Casino, one for the entrance road down the bluff, and the other two along the riverbank.
- Reticulated Micropile Walls – Various Sites throughout the USA. Designed reticulated micropile walls (RMP walls) to stabilize landslides below roadways at: a) the Blue Trail Landslide (U.S. Route 26/89), Lincoln County, Wyoming; b) Relocated Route 14/7, Wirt County, West Virginia; c) U.S. Route 43, Colbert County, Alabama; d) S.R. 136, Dade County, Georgia; and e) U.S. Route 76, Dalton, Georgia.
- Hickman Bluff Stabilization Project, Hickman, Kentucky. Designed a 150,000-sq. ft. wall to stabilize a steep bluff. The design included a row of large pre-stressed anchors to resist deep-seated slope movements.
- Blue Trail Landslide Stabilization, Lincoln County, Wyoming. Lead Design Engineer for three reticulated micropile (RMP) walls to stabilize the Blue Trail Landslide. RMP walls consist of battered micropiles with prestressed anchors all connected to a reinforced concrete cap. The landslide had been moving for the past 30 years requiring continual maintenance by the Wyoming Department of Transportation to relevel U.S. Route 26/89, which is located near the top of the slide. Since construction of the RMP walls in 1996, the slope movements have ceased. The Blue Trail Landslide stabilization project was presented with a National Grand Award for engineering excellence by the American Consulting Engineering Council (ACEC) in May of 1998.
- Signal Hill Landslide Stabilization, Vicksburg, Mississippi. Lead design engineer on design/build team for the Signal Hill landslide stabilization at U.S. Route 61 (Signal Hill) South of Vicksburg, Mississippi. The landslide remediation system incorporated prestressed rock anchors and precast reinforced concrete reaction blocks to stabilize a large landslide which had closed a portion of roadway.
- Lexington Apartments Landslide Stabilization, Belleview, Tennessee. Lead design engineer on design/build team for landslide stabilization at the Lexington Apartments. The landslide was threatening three large apartment buildings at the toe of the slope. The remediation consisted of constructing an anchored soldier pile and lagging wall at the toe of the slope, and two rows of anchors and precast reinforced concrete reaction blocks along the slope. Design also incorporated large French drains to control the groundwater table.
