His experience includes working with both municipal and state agencies. Within the previous 36 months, Mr. Allen has been responsible for over $800,000 in successful engineering planning and design service projects with a total construction value of more than $7,500,000. All of the following projects were completed on schedule and within budget:

  • 2006     Little Elm Lift Station, City of Cedar Park
  • 2006     Glenlake Water system Improvements, Lower Colorado River Authority (LCRA)
  • 2005     Webster Pump Station Sound Enclosure, City of Cedar Park
  • 2005     Liberty Hill Regional Wastewater Facilities, LCRA
  • 2005     Buttercup Creek Cured-In-Place Pipe Project, City of Cedar Park
  • 2004     Buttercup Creek Interceptor Tunnel Construction Administration, City of Cedar Park
  • 2003     Liberty Hill Regional Wastewater Feasibility Study, LCRA
  • 2003     Marble Falls ISD Water Line Extension, LCRA
  • 2002     Eubank Acres Project A, City of Austin
  • 2001     Williamson County Justice Center Off-Site Utilities, Landmark Construction

Example Project Descriptions:

  • Project Manager/Design Engineer for the City of Liberty Hill Pressure Sewer System. Approximately 100,000 feet of 2-8 inch pressure sewer, two lift stations, 9,000 feet of force main, metering stations, and odor control facilities. Total construction costs ~ $4,000,000.
  • Project Manager for the Liberty Hill Regional Wastewater System. Approximately 10,500 feet of 21- and 18-inch interceptor, 2,400-gpm influent lift station and 16-inch force main, 400,000 gallon per day Sequencing Batch Reactor, effluent equalization, tertiary filtration, ultraviolet disinfection, cascade aeration, effluent pump station and effluent force main. Construction cost ~ $4,700,000.
  • Project Manager/Design Engineer for the Glenlake Water System Improvements (2006). Water system modeling and design of a water transmission lines, ground storage tank, and booster pumping facilities for the LCRA.
  • Project Manager/Design Engineer for the Marble Falls ISD Waterline Improvements for the LCRA (2003). This project consisted of designing a new water well system including pumps, piping, and electrical and designing approximately 23,000 linear feet of 8-inch ductile iron waterline. The total construction cost of the project was approximately $850,000. The design was completed on time and within budget. (Reference: David Smith, PMP, with LCRA for reference, 473-3200.)
  • Project Manager/Design Engineer Buttercup Creek Interceptor Tunnel/CIPP Project . The project consisted of approximately 2,000 feet of 52-inch diameter tunnel for a 36-inch diameter interceptor sewer. The preliminary opinion of probable cost for the work was within approximately 2 % of the final project construction costs. The project had a construction cost of $2,000,000.
  • Project Manager for the City of Round Rock East Transmission Main (2004). This was a 16-inch waterline that was designed on a fast-track basis so it could be included with the bidding of a road construction project. The design included approximately 8,400 linear feet of 16-inch restrained joint ductile iron waterline and a 16-inch pressure reducing station. The construction cost of the project was approximately $750,000. (Reference: Don Rundell, P.E., Chief Utility Engineer, for the City of Round Rock for reference, 218-5554.)
  • Project Manager/Design Engineer for 3,400 linear feet of 8-inch diameter sewer in South Congress Avenue for the City of Austin (2003). The project was particularly challenging because we encountered soil contaminated with hydrocarbons in a portion of the work. The construction cost of this project was approximately $700,000. (Reference: Rose San Miguel, Project Manager with the City of Austin for reference, 974-5612.)
  • Project Manager/Deign Engineer for 13,000 lineal feet of wastewater line and 8,700 lineal feet of waterline for the Eubank Acres subdivision (2002). The project had a construction cost of approximately $3,500,000 and was completed with less than 1 percent change orders. The City of Austin used the plans and specifications as a model for other similar projects for the City of Austin. (Reference: Susan Janek, P.E., City of Austin Project Manager for reference, 974-7291.)
  • Construction Phase Engineer for the Southwest Round Rock Regional Interceptor for LCRA (2003). The project consisted of approximately 3,800 linear feet of 30 and 24-inch wastewater interceptor with a construction cost of approximately $1,000,000. The project included an extremely long bore of approximately 500 linear feet and included many post design modifications requested by the City of Round Rock.
  • Project Manager/Design Engineer for the Williamson County Justice Center Expansion (2001). This project consisted of the civil design and site work for the $35,000,000 jail and courthouse expansion. (Reference: David Munk, P.E. with the City of Georgetown for reference, 930-3582.)
  • Project Manager/Engineer for a water and wastewater master plan for the City of Round Rock (2001). The Northeast Water and Wastewater Masterplan analyzed over 20 square miles for water and wastewater future needs. This included extensive water modeling of the City of Round Rock system.
  • Design Manager and Resident Construction Engineer for all utilities (raw water, drinking water, wastewater, electric, communications manhole and ductbank, chilled water, and irrigation water) at a community designed to house, office, and provide work shops for the maintenance of a remotely located oil field in Saudi Arabia (1991-1994). The project included two submersible pump lift stations and an effluent irrigation pumping system.
