Here's just a small sample of some awesome projects we've had the pleasure to work on over the years.

 Combined Sewer Overflow (CSO) Long Term Control Plan (LTCP)

Combined Sewer Overflow (CSO) Long Term Control Plan (LTCP) Seattle, WA

UrbanTech Systems became a sub consultant for CH2M Hill, who primed the project. We worked to address preliminary engineering design for CSO options, including offline storage pipes, offline storage tanks, offline storage micro/tunnels, and the conveyance between the storage facilities and existing utilities.  UrbanTech staff was responsible for creating maps (ArcGIS 9.3), hydraulic schematics (AutoCAD), cost estimates (King County Tabula and an in-house cost estimating tool), and written summaries to detail each option. In addition to organizing all the CSO options by drainage basin, we produced a deliverable for each basin which included a presentation of options and a quantitative comparison between the options available.

 

Council Crest Radio Tower

 Council Crest Radio Tower Replacement Project  Portland, OR

The City of Portland Bureau of Technology Services (BTS) determined that the 440 foot radio tower that supports 911 and other emergency communications at Council Crest Park needed to be replaced.  UrbanTech was the Prime Contractor of the engineering and project management work on this project.  We were responsible for tower and site design, land use permitting, A&E drawings, specs, and bid documents.  UrbanTech assisted the City during the bid process for the design-build project and provided construction administration support.  The Council Crest Tower Replacement began in June 2006 and was completed in December 2008 at a program cost of $1.8 M.  UrbanTech assisted with the design and implementation of the cutover for the 50 radios present at the site.

 

Brightwater Conveyance System

Brightwater Conveyance System, King County, WA

This project included the construction of approximately 13 miles of large diameter tunnels from the new Brightwater Treatment Plant to Puget Sound. It included the construction of a 130 MGD pump station, six reaches of micro-tunneling, facility upgrades for county distribution of reclaimed water and various odor control facility upgrades and new facilities.

  Hidden Lake Pump Station

Hidden Lake Pump Station

Hidden Lake Pump Station, King County, WA

The existing pump station was under capacity and required a conveyance upgrade to 5.4 million gallons per day. UrbanTech provided condition assessment and repair alternatives for five new sections of degraded concrete conveyance trunk. UrbanTech also provided preliminary design alternatives for the improvements to the influent, force main and overflow piping to the new pump station that would permit construction and start-up while keeping the existing pump station in service.  Our firm provided design plans, and specifications for traffic control and erosion sediment control for the new pump station, storage facility and new 6 miles of conveyance pipelines.
