City of Sioux Falls Water Maintenance Building

Parking Lot Improvements

Sioux Falls, SD

 

Owner:  City of Sioux Falls

Design:  2015

Construction: 2015/2016

 

The City of Sioux Falls planned to reconstruct the existing parking lot adjacent to the Water Maintenance Building located at 668 W. Algonquin Street.  The surfacing within the existing parking lot had met and exceeded its useful life and was in need of replacement.  The topography of the existing parking lot was very flat and the City looked to improve the overall drainage characteristics of the site by evaluating options of increasing the grades within the parking lot and installing storm sewer and inlets.  The City would also like to incorporate water quality improvements by treating the runoff where it is conducive to do so while at the same time maintaining the existing parking capacity and vehicular patterns.  Additional improvements included an enclosure for dumpsters and evaluation of parking lot layout.

Survey services included topographic, boundary, and utility surveys.  Civil Engineering services included parking lot layout, grading, erosion control, site utilities, and drainage analysis.

 

2014 Neighborhood Water Main Improvements

Sherman, Van Eps, Blauvelt, Wayland and Mable Avenues

 

Owner:  City of Sioux Falls

Design:  2013

Construction: 2014

 

InfrastructureDG was hired by the City of Sioux Falls to provide Project Management, Public Involvement, Design, Bidding, and Construction Administration services for this project.

Project consisted of water main installation across fifteen blocks of residential streets.  Design included phasing of the improvements to accommodate residential access and overall improvement sequencing.  There were a total of five phases to complete the project improvements.  Each phase included a separate calendar day count contract with an overall project completion date.

Temporary water was necessary on two of the five phases because the new main had to be placed in the same location as the existing main.  Replacement of the main within the same location was a result of bedrock being present within the two phases.

Additional improvements consisted of sanitary sewer repairs, water and sewer services, storm sewer repairs, grading, gravel, ADA sidewalk ramps, curb repairs and roadway paving.

 

Xcel Energy - Cadastral Survey

Brookings, SD to Big Stone, SD

 

Owner:  Xcel Energy

Date:  2013

 

This project included a full Cadastral Retracement Survey for a proposed 345kV transmission line corridor. The new transmission line starts in Brookings, SD and runs north to Big Stone, SD encompassing approximately 75 linear miles. The line crosses into three counties, Brookings, Grant, and Deuel. We started the project by ordering all of the original government survey notes and plats from the SD State Archives office and by conducting research at each of the three counties Register of Deeds offices. We obtained copies of all Certified Land Corner Records, Subdivision Plats and Boundary Surveys along the proposed route. We began the initial field survey by excavating with a tracked mini-excavator for original stone monuments set by the Government Land Office in the late 1800’s at the township corners. We then completed the search for all section and quarter sections corners along and adjacent to the route using computed locations from the record documents. After all computations were complete we re-monumented the missing corners with a rebar and surveyors cap. We also corner ties and drafted Certified Land Corner Records for all monuments that we set as well as all monuments that we accepted that did not have existing Corner Records. We recovered and/or re-established approximately 350 Public Land Survey System Corners.

Centerville Safe Routes to School

Centerville Economic Development

 

Owner:  City of Centerville

Design:  2013

Construction: 2014

 

The City of Centerville received grant funding through the Safe Routes to School (SRTS) program.   We coordinated with the City in identifying the proposed route and necessary improvement areas, completing preliminary cost estimates, and assisted with the grant application.  SDDOT Coordination was necessary throughout the entire project as funding was administered by the SDDOT and the project would be let by the SDDOT.  In addition to the design and plan production of the sidewalk and ADA improvements, the project also included topographic survey and an encroachment survey.

 

The City intends to assess the adjacent property owners for the new sidewalk to aid in funding the City’s portion of the project.  To assist the City, we completed an assessment schedule for the improvements.
