The firm has a strong background in public infrastructure, especially in New Braunfels and Comal/Guadalupe Counties. HMT Engineering & Surveying is the only firm to have assessed and inventoried every City street within the City, and after the completion of the New Braunfels Utilities System Mapping project, HMT Engineering & Surveying will be the only firm to have surveyed all of NBU’s sewer manholes, fire hydrants and water valves.

HMT Engineering & Surveying knows the City of New Braunfels infrastructure better than any other firm.

Katy Street Drainage Project - S. Craig Hollmig Inc. (SCH) was retained by the City of New Braunfels and New Braunfels Utilities to provide professional engineering and surveying services for the Katy Street Drainage project. The project included approximately:

• 2900 linear feet of street reconstruction with curbs, drives and associated street appurtenances, 470 linear feet of 5’x4’ and 850 linear feet of 7’x4’ concrete box culverts, 1800 linear feet of 18” to 30” RCP storm drain, with associated inlets, channels, and drainage appurtenances, 2800 linear feet of 8” and 400 linear feet of 12” sewer replacement and associated appurtenances, 320 linear feet of 6” and 3100 linear feet of 8” water main replacement, fire hydrants, valves, and associated water appurtenances.


• SCH’s responsibilities included, topographic surveys, ROW locations, engineering design for streets, drainage, water and sewer, preparation of bid documents, attendance at public meetings/workshops, construction administration and construction staking. Total project bid was just over $2.4 million.

Other City of New Braunfels projects with similar requirements:

• Walnut Avenue Extension – IH 35 to County Line Road, City of New Braunfels
• Forest Drive Street and Drainage Improvements
• 2006 Street Rehabilitation Phase 3-06
• HEB Soccer Fields Parking Lot for Parks Department
• Cypress Bend Park Parking
• Ridge Hill Culvert Improvements
• Goodwin Lane Culvert & Sewer Improvements

Pavement Assessment – City of New Braunfels - HMT Engineering & Surveying was a sub consultant on a team retained by the City to develop a pavement management program for all the city streets owned within the corporate boundaries of the City of New Braunfels. HMT’s role was to visually assess the entire street network. HMT assessed just over 285 miles of City streets to determine street surface conditions. In addition to street conditions, other information gathered included drainage, curbs, lane widths and number of lanes and sidewalks. All of the information gathered was input into an Infrastructure Maintenance and Management Program (IMMP) database. HMT utilized AutoCAD, IMMP and ESRI GIS software to perform the work.

Walnut Widening Project – Sewer and Water - HMT Engineering & Surveying has been retained by New Braunfels Utilities to provide professional engineering and surveying services for the design of new water and sewer mains in connection with the City’s Walnut Widening project. The project is a joint bid project with the City of New Braunfels. The limits of the project consist of approximately 8400 linear feet of Walnut Avenue, from Landa Street to I.H. 35. Approximately 16,000 linear feet of 6”-8” sewer line will be evaluated and possibly replaced and approximately 16,000 linear feet of 6” to 12” water mains will be evaluated. HMT’s responsibilities include, topographic survey, design of water and sewer lines, coordination with the City and their design consultant, attendance at public meetings, and construction administration.

• New Braunfels Utilities Water & Sewer Asset Inventory - HMT Engineering & Surveying has been retained by New Braunfels Utilities to develop an updated GIS database of all sewer manholes and water valves within their system. The data will be closely tied to the pavement management database to enable the City and NBU to better manage their assets. HMT responsibilities include using survey grade equipment to locate the x, y, z position of all manholes and valves. Additional field investigations will be made to determine manhole inverts and conditions. All the data collected will be “dumped” to a GIS database. It is estimated approximately 6500 manholes and 8000 water valves will be located and placed into the database.


• Cibolo Creek Municipality Authority- Olympia-Retama Sewer Rehabilitation Study - HMT Engineering & Surveying was retained by CCMA to provide professional engineering and surveying services to analyze the collection system rehabilitation needs from the M.K.T. Railroad downstream to the Olympia lift station. The project consisted of assessing the condition of the manholes and flow characteristics within the pipe. The assessments efforts were supplemented by an inspection contractor, who provided manhole and pipe assessments for approximately 90% of the sewer collection system. The project was expanded from the Olympia-Retama section, to include the Maske Rd and Schertz sewer lines from FM 1518 and Maske Rd downstream to the Schertz lift station. HMT also submitted the Preliminary Engineering Report that was included in the application to the Texas Water Development Board. The application and Preliminary Engineering Report were approved and the project has moved forward into the Planning and Design Phases.
