JAMES COLEBY GIBSON
CAD Design including Civil 3D
A.S. – Applied Science, Pellissippi State Community College Specialized in Computer Aided Drafting and Design
Coleby has been with LDA for 12 years. He has experience as a survey crew chief, CAD designer, computer and information technician, and field resident project representative throughout his time at LDA. In addition, Coleby is experienced with data collection and the importance of gathering utility location data necessary for accurate database information.
The time had come for City of Memphis to update some of their old sanitary sewer lines. One in particular was a 36-inch interceptor line which ran in and around the Rodney Baber Park area. The line had become extremely deteriorated. Added with the unstable ground within the park the decision was made that this was an engineering emergency and plans had to be made quickly. Coleby was the lead CAD designer on the project. He worked side by side with engineers and collaborated with personnel from the City of Memphis to create a detailed design package including a realignment and upsizing of the old interceptor line.
The City of Oak Ridge had sanitary sewer issues mostly caused by ground water leaking into the old pipes and manholes. Coleby served as the project representative during the construction services of the project. Everyday, he collaborated with the project engineer and contractor to discuss the status of the project, address any concerns, and make sure the contractor stayed true to the specifications of each rehabilitation process. He was responsible for keeping a daily log of the progress the contractor made and updating field map information which assisted in the creation of record drawings.
Survey Crew Leader and CAD Designer, Tannery Knob Water Tank Replacement, Johnson City, Tennessee (2016-PRESENT)
LDA Engineering was selected to aid with the design and planning of replacing the Tannery Knob water tank. Studies showed that the present water tank was deteriorating and showing signs of leaking. Not only were plans needed for the new water tank but there needed to be plans for demolishing and removing the old tank. Coleby was crew chief of the survey team responsible for collecting the existing utility and topographic data necessary for the engineers to evaluate and construct an elaborate plan for the removal and replacement of the old tank. Volumes of the existing and finished grounds were needed to calculate how much earth would have to moved or brought in for this project. Coleby was able to aid the engineers with these calculations by creating 3D models of the existing and proposed surfaces. By comparing these surfaces the volumes needed could be derived.
Survey Crew Chief and CAD Designer, Pigeon Forge Beneficial Reuse Distribution Line Phase I, Pigeon Forge, Tennessee (2014)
The City of Pigeon Forge came to LDA Engineering seeking help with designing a new 12- inch effluent reuse line that would service the new Ripken Experience baseball park and surrounding area businesses. Coleby had the task of surveying/field inspecting the designated route for existing utility data and topography of the areas included. He then generated drawings from the survey information with which combined with the engineer’s design, an easily interpreted planning package was developed.
An evaluation of the City of Maryville’s facilities needed to be performed to determine if they were ADA compliant. Data collection for the evaluation was conducted using the GeoDOT program, which produced forms displaying the facility information gathered including sidewalks, curb ramps, pedestrian signals and onstreet parking. Coleby is leading a team responsible for obtaining the necessary information in order to obtain an accurate evaluation of all facilities in question.
