Survey Projects

 

SR 522/NE 195th Street Woodinville-Snohomish Road Topographic Survey, City of Woodinville

The City requested that Roth Hill Engineering Partners, LLC, provide surveying services for this project. The site horizontal datum was based upon existing WSDOT survey drawing and vertical datum was NAVD 88, tied to local WSDOT control with reference benchmarks established and used to provide topographic mapping. The deliverables included AutoCAD version 2005 hardcopy drawing and electronic file of same for topographic survey.

Sanitary Sewer System Aerial Mapping and Topographic Survey, City of Carnation

Survey_Projects1.jpgOur survey team provided a geodetic control survey of approximately 2 square miles for the aerial mapping of the City of Carnation. This survey was performed utilizing static GPS survey to establish over 30 control points for the aerial mapping, which serves as the base maps for a sanitary sewer collection system design. This precise control network allowed for 1-foot contour mapping. We also provided additional topographic survey (conventional total station and data collector) in addition to the digital orthophotography to support all applicable design elements.

Juanita Interceptor Sewer Project, City of Kirkland

Roth Hill performed topographic design survey on this major sewer replacement project. Several existing utilities were present in the main arterial roadway which required coordination with Northshore Utility District, King County, and other franchise utilities. Roth Hill provided surveying, feasibility study, design, permitting, management of wetlands biologist, geotechnical and structural engineering subconsultants, preparation of contract documents, full-time construction observation, construction administration, and construction record drawing preparation.

1998 - 2004 Water System Improvements, City of Kirkland

The City of Kirkland chose Roth Hill to provide surveying, design, preparation of contract documents, and full-time construction observation for their 1998, 2000, 2002 and 2004 Water System Improvement projects due to our track record of success with the prior water system improvement project. This project typically involves replacing over 4,000 linear feet of undersized and aging watermains with new 4- and 8-inch ductile iron pipe on several of the City’s residential streets. Roth Hill ran control down into the project areas, provided topographic maps and right-of-way delineation.

2004 Watermain Replacement “F” Project, City of Everett

Roth Hill provided topographic surveying, design, and public involvement for this watermain replacement project. As part of a bi-annual watermain replacement program for the City of Everett, 6,700 linear feet of existing asbestos cement (AC) watermains were replaced with 8-inch ductile iron (DI) pipe on three separate streets—Madison Street (from Beverly Lane to Fleming Street, Berkshire Drive and 63rd Street SE (from Evergreen Way to Beverly Boulevard), and West View Drive (from 52nd Street SE to 47th Street SE). Roth Hill ran control down into the project area, provided a topographic map and right-of-way delineation. Roth Hill also provided construction administration support and will prepare construction record drawings upon completion of the project.

Fairweather Park Boundary and Topographic Surveys, City of Medina

Roth Hill performed a boundary and topographic mapping survey for the City’s Fairweather Park. The park includes tennis courts, walking trails, grass fields and large wooded areas with steep slopes.

Geodetic Mapping Control, Soos Creek Water & Sewer District

Roth Hill conducted approximately 100 square miles of 2nd order mapping control survey. Geodetic control was established in this survey with GPS technology.

Sammamish River Mapping, City of Redmond

Survey_Projects2.jpgThe City of Redmond solicited the help of the Roth Hill survey group to map an 800-foot stretch of the Sammamish River channel. The project entailed topographic mapping of the banks, trails along the river and a hydrographic survey of the river's channel bed. The banks proved to be straightforward enough, though at times the blackberry bushes were pretty thick, but the channel bed was a little more challenging. The river was pretty wide through this stretch and not shallow enough to wade across, so a raft and two 100-foot lengths of rope were employed to get the channel bed shots. The procedure involved the rodman, or the person with the prism pole, in the raft and a person on either bank holding the raft in place with rope. The fourth member was at the instrument collecting the shots. Holding the raft against the slow current proved tougher than first thought, but the crew held on in the rain and by the end of the day, the channel bed shots needed for the cross sections were acquired. Roth Hill then generated a topographical map of the river in AutoCAD based on the City of Redmond's horizontal and vertical datum.

Foundation Staking, Chaffey Homes

Survey_Projects3.jpgSince 1998 Roth Hill has been providing foundation staking and layout services for Chaffey homes. We have provided services on multiple subdivisions throughout King and Snohomish Counties.

Storm Drainage System and Road Improvement Surveys, City of Medina

Roth Hill performed boundary and topographic mapping surveys and construction staking for the following City projects:

  • NE 24th Street Stormwater and Roadway Improvements
  • Overlake Drive Phase 1 and 2 Stormwater, Roadway and Pedestrian Improvements
  • Wheeler Avenue Drainage Improvements
  • NE 28th Street to 80th Avenue NE Storm Drainage Improvements
  • NE 12th Street, Evergreen Point Road Phase II Road and Drainage Improvements
  • 77th Ave NE and Evergreen Point Road Drainage and Street Improvements

Construction Staking, City of Redmond

Roth Hill provided construction staking for the Redmond Well No. 4 project that included storm improvements and building and piling locations. This project was the 2003 APWA project of the year for the $2M - $10M Environmental Category.

Topographic Surveys and Construction Staking, Soos Creek Water & Sewer District

Roth Hill has provided ongoing topographic mapping and construction staking for water and sewer system contract work and developer extensions throughout the District for the past 35 years. The following are some examples of larger projects:

  • 6 Million Gallon Reservoir
  • SW Sewer Service Extension
  • SE 256th Sewer Conveyance System
  • Lake Wilderness Trail Trunk Sewer

Topographic Surveys and Construction Staking, King County Water District No. 90

Our survey crews performed topographic mapping surveys and construction staking for more than 35,000 linear feet of watermain for the District. The following are some examples of larger projects:

  • SR 900 Watermain Replacements
  • May Valley Road Watermain Replacements
  • Licorice Fern 2 Watermains
  • Miscellaneous Watermain Replacements (5 locations throughout District)

Topographic Surveys, King County Water District No. 111

Roth Hill has completed topographic mapping surveys for watermain and reservoir projects throughout the District for the past 10 years.

Auburn Yard Topography and Construction Staking – Hanson-Wilson, Inc., and BNSF

Roth Hill performed 12,000 feet of cross-sections and topographic survey for BNSF Auburn Yard improvements near BNSF’s facility at 1315 A Street, Auburn. The topography included mapping of existing parallel tracks and cross sections for earthwork. The construction phase included staking construction baselines and several new parallel tracks, curves, and switches. Post-construction record data was also gathered to calculate new yard capacity.

Inspection Facility Access Road Survey, Hanson-Wilson, Inc.

Roth Hill performed surveying services on behalf of Hanson-Wilson, Inc., for the Inspection Facility Access Road in Swift, Washington. This project involved construction staking for approximately 1,900 linear feet of access road for the new U.S. Customs Inspection Facility on BNSF railroad right-of-way in Whatcom County. The Roth Hill survey crew worked directly with the general contractor in construction of the project. Hanson-Wilson staff provided input on the construction staking relative to the design plans.

Bridge No. 119 Topographic Survey, Hanson-Wilson, Inc.

Roth Hill also performed a topographic survey of Bridge No. 119 in Kittitas County, Washington, for Hanson-Wilson, Inc. This project was a detailed survey of an existing BNSF bridge over the Yakima River. Roth Hill provided mapping of the existing base rail, horizontal alignment, and profile for the bridge and adjacent track sections. This project required adherence to the safety standards of 49 CFR Part 214 for Bridge Worker Safety Standards. Any work in BNSF rights-of-way require all of Roth Hill’s field personnel to be certified for safety through the Contractor Orientation Course.
