Main Avenue Reconstruction

SRF prepared project scoping, environmental documentation, preliminary and final design, and engineer of record services for the reconstruction of Main Avenue (US Hwy 10) from University Drive to 2nd Street in the City of Fargo. The purpose of this project is to mitigate identified system deficiencies (utilities, traffic operations), safety issues (access and crash), and capacity constraints (deficient roadway geometry and right-of-way) and also provide opportunities for an enhanced business environment, improve safety and convenience for pedestrians, and create a safe and efficient transportation corridor that supports regional and local traffic needs.

The project included the full replacement of the street section and underground utilities from right-of-way line to right-of-way line. During preliminary design, SRF evaluated five different lane configuration alternatives and six options to add on to the alternatives. In addition, the drainage system was found to be significantly undersized by today’s design standards.  The myriad of underground utilities to avoid also complicated the design.  We used XP-SWMM hydrologic and hydraulic modeling software to evaluate the existing system and incorporate changes to provide a higher level of flood protection. Coordination with other projects in the area, including a new lift station, was also critical to the ultimate design.

Public engagement was central to selecting the preferred alternative, and visualizations were used to clearly show members of the public what each alternative would look like.

SRF’s project controls team developed a critical path method (CPM) design schedule and a contractor-style CPM schedule to determine construction staging and time. We created a 4D schedule using Synchro Pro 4D to tie the construction time schedule to the project 3D model, which allowed the construction sequencing to be reviewed in relation to the work effort and construction time. The 4D schedule was critical in assessing construction staging and illustrating space constraints of the work area to justify full closure by segment.

“On behalf of the City of Fargo, I want to thank everyone involved with the Main Ave project. I honestly don’t think the project could have gone much better and the credit goes to everyone involved; the design team, prime contractor, subcontractors, utility companies, project management and project inspection staff. Thank you all for the great work that you did!”
