Services We Provide
Teran Group provides services in surveying and mapping, 3D scanning, civil engineering and project management as both a primary and subcontractor.

Surveying and Mapping

Teran Group provides Survey and Mapping Services including Boundary Surveys, Topographic Surveys, Hydraulic and River Crossings, Aerial Mapping, Commercial Sites, Construction Layout and 3D Laser Scanning. Teran Group takes pride in offering the most reliable and state-of-the-art land surveying services to all of our clients. As a means of providing this excellent quality, Teran Group is proud to be among the few who fully utilize the Global Positioning System (GPS) – a constellation of 24 highly specialized satellites. GPS has revolutionized the way surveyors perform their essential functions by combining dramatic productivity gains with remarkable accuracy. Also used are Leica robotic and reflectorless total stations, TDS Ranger data collectors and processing through LGO and TGO into ASCII, AutoCAD and MicroStation Format.

3D Scanning

Our newest addition, 3D Laser (LIDAR) Scanning, provides Teran Group with surveying and design capabilities unimagined just a few years ago. The terrestrial laser scanner system, the RIEGL LMS-Z390, consists of a highly accurate and fast 3D scanner, associated operating and processing software RiSCAN PRO, and a calibrated and definitely orientated high-resolution digital camera. The system provides data which lend itself to automatic or semi-automatic processing of scan data and image data to generate products such as textured triangulated surfaces or orthophotos with depth information to an accuracy of ¼”. In addition to RISCAN PRO, post processing of scanned data is performed with PHIDIAS AND TERRASOLID which also run in MicroStation.

Subcontracting Services

Since the founding of Teran Group, we have provided subcontracting services to a multiple number of companies in the land surveying area. Our company is registered as a HUB with the State of Texas and other governmental agencies in Texas. Our major clients include consulting firms and contractors. We have performed surveying services doing topographic and boundary surveys and preparation of plan and profile drawing for consulting firms. For contractors we have performed construction staking services for different types of projects such as METRO rail, building layout, runways and aprons for airports, roadways, utility lines and other types of structures. Another service we can provide as sub consultant. We also can provide inspection services as a subcontractor to other Construction Management firms.

Another area of subcontracting that we can perform is with our terrestrial 3D scanning with photogrammetry. We can perform the topographic survey and use the data for preparation of topographic survey with delivery of photography all incorporated in Google map helping the designers in performing their design work more efficient. The same information can be used during construction for risk management.

Teran Group brings more than 27 years of experience as subcontractor through the experience of its CEO Mr. Orlando Teran, P.E., R.P.L.S.
