PROFESSIONAL SURVEYING
Our survey department has a broad base of experience on topographic, boundary, hydro-graphic, roadway, levee, coastal marsh and other types of surveys. Our survey data is obtained using electronic total stations/data collector sets, Real Time Kinematic (RTK) GPS systems, conventional levels and hydro-graphic (Fathometer) equipment. Data is typically saved in electronic files for direct download into Auto-CAD, Micro-Station or other mapping software. Survey projects are carefully planned to utilize proper vertical benchmarks, horizontal reference marks and appropriate datum.
US 61 /Scenic Hwy Corridor Enhancement Project
For MOVEBR
As part of MOVEBR's Enhancement Program, GOTECH was selected to perform surveying and preliminary engineering services for US 61 / Scenic Highway from LA 408 / Harding Boulevard to Swan Avenue. The scope of work includes a topographic survey, traffic study, existing drainage map, drainage design, green infrastructure report, typical sections, plan and profile sheets, a design study, and preliminary design report. GOTECH interfaces with various stakeholders within the community (e.g. Build Baton Rouge, Southern University, Scotlandville Neighborhood Advisory Committee, the MOVEBR Program Management T earn, and LADOTD representatives while producing technical concepts to address the purpose and need of the project. Project concepts are constrained by existing Right-of-Way and limited local dollars but will include ADA compliant sidewalks, on-street bike lanes, traffic calming countermeasures, transit stop improvements, and green infrastructure (e.g. biofiltration swales and curb extensions).
Louisiana International Terminal Site Plan Topographic Surveys & Utility Mapping
For the Port of New Orleans
Working as a Subconsultant to C.H. Fenstermaker, LLC, GOTECH conducted a topographic and utility survey of the Port of New Orleans facility at Violet, Louisiana. The project site is located on the east bank of the Mississippi River at River mile 84 in St. Bernard Parish. The sites are bordered by the Mississippi River on the west and LA Hwy 39 (E. Judge Perez Drive) on the east. The GOTECH survey crews verified control points that were established at the site. GOTECH also established other primary and secondary GPS control points that were used as reference points for the work. GOTECH investigated the existing utilities on site and received information on utility companies with lines in the area:
Gulf South Pipeline - Atmos Energy - AT&T Distribution - MCI Communications - Cox Communication - Entergy Louisiana, LLC
Upon completion of the field survey, the data files were processed, and a final AutoCAD Civil 3D drawing file was computed. The base drawing file containing the data collection points attribute data and connecting linework was delivered to Fenstermaker for review and final processing. The data file included utility survey points showing the location of overhead electric lines, utility poles, overhead communication lines, meters valves, manholes, telephone pedestals, electric transformers, drainage culverts, guy wires, pipeline markers, and low wire points.
Nicholson - Plank Bus Rapid Transit Corridor Project
For MOVEBR
As part of MOVEBR's Enhancement Program, GOTECH was selected to perform surveying and mapping services for the Nicholson-Plank Bus Rapid Transit Corridor Project. The project footprint extends from Nicholson Drive (LA 30) at Skip Bertman Drive to Plank Road (LA 67) at Airline Highway (US 61 / US190). The scope of work includes a topographic survey, cross section survey, right-of-way survey, utility survey, and mapping services. This 8.2-mile-long corridor survey includes different design elements such as subsurface utilities, subsurface drainage, median cross sections, urban and suburban contexts, pedestrian and transit facilities, and a significant amount of data overall.
Louisiana Watershed Initiative (LWI) Modeling Contract Region No. 2 & No. 3
GOTECH was a member of the Freese & Nichols (FNI) Team for the Louisiana Watershed Initiative Modeling Master Drainage Plan Project. Region 2 was an area generally located between Monroe and Alexandria in North Louisiana. Topographic and bathymetric surveys were completed in the lower Ouachita basin. GOTECH crews collected field data on the lower Ouachita River and the lower Red River areas. Control surveys were completed by way of GPS observations in the field. A minimum of three control points were set at each structure. The Ouachita River surveys covered a stream length of approximately 130 river miles, including 46 cross sections. There were over 100 structures surveyed in the Ouachita River watershed and 35 structures surveyed in the Red River basin. The structures were classified into 5 categories: Bridge Major, Bridge Large, Bridge Small, Culvert Large and Culvert Small. River surveys (hydrographic) were completed using single beam fathometer equipment to produce stream cross section data. Survey data was compiled into electronic spreadsheets for use by the FNI modelers.
GOTECH, Inc. was a survey team member for the LA Watershed Initiative Region 3 Project. Serving as a subconsultant to WSP Consultants for the drainage master plan project. GOTECH field crews collected survey data in the Bayou Macon Basin. Located in the Momoe area of North Louisiana, the work included 105 stream cross sections and 164 structure surveys. Control surveys were conducted at each structure site. GPS observations were made to establish northing, easting and elevation data for each control point. GOTECH crews obtained specific data on bridges (pier locations, low chord elevation, deck information, railing shots, cross sections) and at culvert structures (invert, geometry, cross sections, etc.). The data was submitted to WSP for their modeling effort.
Acadian Rd Roundabout, Route LA 20 (Canal Blvd) & Local Routes (Back Street, Jackson Street, Thompson Place)
For LADOTD
GOTECH, Inc. provided a complete topographic survey required for the design of a roundabout at the existing intersection located in Thibodaux, LA. The survey was completed in accordance with LADOTD Standards and included all utilities with depths, all drainage structures, and DTM for the survey area. The project survey control and horizontal alignment was based on the Louisiana State Plane Coordinate System, (NAD-83-92) as determined by G.P.S. observation. The project also included right-of-way surveys and the preparation of right-of-way maps .
