TxDOT – Statewide Bridge Clearance
About the Project
CLIENT
TxDOT
LOCATION
Statewide
PROJECT TYPE
Mobile LiDAR, GIS
G&AI acquired and processed 1,760 bridges in various locations around the State of Texas for the TxDOT Bridge Clearance project. Bridge elements were extracted to generate horizontal and vertical clearances for each bridge opening, in both directions. Clearance information was placed in an ArcGIS 3D geodatabase, where a datasheet with images of each bridge were generated. Deliverables included an ESRI geodatabase.

About the Project
Line J | Section 1 108-inch Diameter Pipeline
Tarrant Regional Water District commissioned the installation of this 108-inch steel pipeline between Kennedale Balancing Reservoir and Arlington Outlet with an attendant research program for the use of Controlled Low Strength Materials (CLSM) trench backfill.
Gorrondona & Associates, Inc. assisted TRWD through our contract with Freese & Nichols, Inc. (FNI) in order to evaluate the potential use of native excavated trench materials with various stabilizing agents for pipe bedding and backfill.
G&AI worked in tandem with the contractor, the contractor quality control laboratory and the University of Texas at Arlington to evaluate the compressive strength of the various design mixes for CLSM tested.
G&AI prepared numerous CLSM cylinder specimens in accordance with ASTM D-1633 Standard Test methods for Compressive Strength of Molded Soil-Cement Cylinders. Curing and testing was performed for 3, 7, 14 and 28-day breaks under tightly controlled strain-controlled tests. Comparative laboratory tests by the other parties were evaluated to select the best cement / admixtures ratios for production with native excavated soil.
G&AI prepared field CLSM cylinders, cured in the lab and performed compressive strength tests. G&AI instructed contractor personnel to prepare CLSM cylinder test specimens. G&AI witnessed CLSM blending in a pug-mill before placement.

About the Project
Komatsu worked with the City of Grand Prairie to plan and design their first branch library in 2001. The City returned to Komatsu in 2016 when they wanted to renovate and enlarge the original 10,000 sq. ft. facility to 16,550 sq. ft. This project was phased in order for the library to remain occupied for as long as possible. Added square footage is dedicated to technology and new concepts in library design allowing for more program space. Construction was completed on time and on budget.
CHARACTERISTICS:
– Children’s and Adult’s Programming Areas
– 6 Staff Work Stations
– 2 Manager Offices
– 10 Computer Stations
– Self-Checkout Stations
LOCATION: Grand Prairie, TX
PROJECT TYPE: Renovation and Expansion
