Topographic Surveys Projects

Topographic survey - Federal Courthouse 300 Fannin St.– Shreveport, LA:

A&A was tasked with performing a topographic survey in 2023 of the complete parking lot showing any above ground features, as well as drainage patterns. Survey research was performed as well as older company records to find any relevant information. Because the subdivision of downtown Shreveport was established over a hundred years ago, it has gone through significant changes. Company survey records of maps from the 50s were utilized as well as other older surveys were incorporated into this job. Because it was a topographic survey top of curb and gutter elevations were obtained. Inverts of drains as well as temporary bench marks were established for a potential future construction project.

Topographic Survey - Union Train Station - Texarkana, Arkansas:

A&A was tasked with performing a topographic survey of the complete station on both sides of the state line, and a boundary survey for the station located on the Arkansas side. Survey research was performed and a local firm that had previously produced surveys of the station in the 90s was contacted so that copies could be obtained. Amtrak had a previous survey of the station from 2012, which was also used as a reference. The survey data from that survey was made available by Amtrak, and it was incorporated into our survey to increase its accuracy. An USGS Vertical Bench Mark on the face of the station building on the Texas side was also tied down. The USGS Bench Mark No. B-95 was the vertical basis for the survey. Railroad safety training and courses also were required for the project, both for Amtrak as well as Union Pacific.

Topographic Survey - Choice Neighborhood – Shreveport, LA:

A&A was asked to produce a detailed boundary & topographic survey of lots 53-70 of Boisseau Annex Subdivision, and lots 51-70 of Shepherd & Stuart Subdivision in Shreveport. The A&A survey crew data collected the entire 4.396 acre city block to generate & produce the topography for the finished survey. The survey was produced for SPAR to be used as the basis of a design project. The A&A crew found existing monumentation in the field, and set monuments as needed. Appropriate easements on the property were identified and shown, and it was identified whether or not they impacted the site. A&A performed all of the field work, drafting, and produced the final plat in house.

NAVFAC BAFB - Entrance Road & Gate Complex Phase I & II - Bossier City, LA:

A&A was tasked with performing a topographic survey for both phases of the construction portion of this project. The specific project is the extension of the Interstate 220 loop into Barksdale Air Force Base. Providing a new secure entrance for Base personnel to enter the air base off of Interstate 20. This complex is a sophisticated 21st century design, and needs first order accuracy due to project requirements. A&A tied into existing monumentation set previously on other surveys, USGS monument along Interstate-20, and base monuments. A&A performed topographic surveying to obtain and calculate cut & fill quantities to establish a comparison between the existing ground, what dirt was excavated, and finally the embankment fill that was placed on the site. The existing ground was low lying swamp land, the project design required an interstate roadway to be placed along the route. Thus there was a significant amount of embankment required for the project. This multi-year contract is currently ongoing.
