NCDOT Project Scoping Process

Derrick Lewis, P.E., Unit Head, Feasibility Studies Unit, NCDOT

Description: The feasibility studies process has undergone changes in the past few years. We will look into current Express Design and Project Scoping Report processes implemented for feasibility studies.

Questions: 10-15 minutes


NCDOT Integrated Project Delivery (IPD)

Derrick Weaver, P.E., CPM, Unit Head, Environmental Policy Unit, NCDOT

Description: A update on the IPD process will be provided. We will also explore tools for streamlining the process from concept through construction using the latest technology and information available.


• Break: 2:45 pm


Project ATLAS Updates

Eric Wilson, GISP GeoDecisions, A Division of Gannett Fleming

Ryan Arthur, Data Analyst, NCDOT

Description: We will provide an update on the Project ATLAS program and provide latest new and information regarding deployment of this screening tool.



2D Hydraulic Modeling and Visualization

What is a Feasibility Study?


A Feasibility Study is a preliminary engineering and funding evaluation of a

candidate State Transportation Improvement Program (STIP) Project. It is the initial step in the planning and design process and not the

product of exhaustive environmental or design studies.

4

What is the Purpose?


The purpose of the feasibility study is to describe the proposed scope of improvements, provide the associated costs and impacts, and identify potential concerns or problems within

the project area.

5

How is it different from a

STIP Project?


A Feasibility Study is a high-level engineering study that develops conceptual designs of potential improvements in order

to determine the anticipated costs and impacts for programming purposes.

Once programmed it becomes a STIP project in which the department performs exhaustive environmental and design

studies as well as comprehensive public involvement to satisfy the National/State Environmental Policy Act (NEPA/SEPA) planning process and complete the ultimate design to be

implemented in the construction phase.

6

What are the Pros & Cons of a

Feasibility Study?


Pros: Provides preliminary cost and design data without the expense of a full study. A Feasibility Study gives enough

information to make an educated decision on prioritizing and programming a project.

Cons: It is only a conceptual design with minimal public input and without environmental field studies. The cost estimates are

preliminary and not a definite answer of what it will cost as other issues may arise during later planning and design stages.

7

STI Law

As a result of the Strategic Transportation Investments Law (STI) prioritization process, a majority of new project requests are to upgrade existing facilities

A substantial increase in the volume of candidate project requests being submitted with little to no formal evaluation or support documentation

In order to accomplish the efficient review of these candidate projects, a new methodology was required to clarify the scope of projects and provide more accurate cost estimates

A new two-step process has been created to fulfill these needs: Express Design Evaluation and Project Scoping Report


Overview

8


OverviewWhat the process IS:

Initial step in the planning and design process for a candidate project

Describes the project, estimates preliminary costs, and identifies any potential problems

Investigates conceptual design option(s) and prepares costs needed for the prioritization process (SPOT)

9AN alternative, not THE alternative


Overview

What the process is NOT:Detailed engineering

In-depth data collection or field studies

NEPA/SEPA compliance documentation

10


11

DISCLAIMER:

The Project Scoping Process is NOT intended to satisfy NEPA/SEPA requirements for a project, nor

be an exhaustive investigation of design and environmental issues. Appropriate NEPA/SEPA

documentation must be completed during the project development phase of a project before the project

will be approved for right-of-way acquisition or construction.

Natural Environment

• Areas of Environmental Concern–An AEC* is an area of natural importance: It may be

easily destroyed by erosion or flooding; or it may have environmental, social, economic or aesthetic values that make it valuable to our state.

–Areas of Environmental Concern (AECs) are the foundation of the Coastal Resources Commission's permitting program for coastal development.

I've wasted so much of my time in the past searching for files; this

will save time!

It was far better than I expected. The search, screening, and workbench tools are an absolutegame changer!

Exceeded expectations

Great tool! Thank you for listening to suggested updates/improvements for 2.0.

The software is user friendly.

I think Atlas is a great idea and

long overdue.Thank you for your efforts, communication between agencies is key! Please share with SCDOT too!

I was blown away by the organization and fully covered process.

This is one-stop shopping for preconstruction and streamlineswhat I need to prepare before going in the field.

ATLAS Feedback

I was nervous because I am not tech savvy, but thiswas very simple.

As a consultant PM, this system will be greatto track progress and to provide screening.

Atlas will be a highly effective method of delivering projects more efficiently.

Fantastic tool,

can't wait to use.

I see myself using this daily.

Great interactive, useful tool!

SRH 2D (SMS) vs. HEC-RAS2D Modeling Overview

6

SRH-2D2D Modeling Overview

• Major capabilities of the SRH-2D flow solve include:• 2D depth-averaged dynamic wave equations (the standard St. Venant equations) are solved with the finite-

volume numerical method;• Steady state (with constant discharge) or unsteady flows (with flow hydrograph) may be simulated;• An implicit scheme is used for time integration to achieve solution robustness and efficiency;• An unstructured polyhedron mesh is used, which includes the structured quadrilateral mesh, the purely triangular

mesh, or a combination of the two. Cartesian or raster mesh may also be used. In most applications, a combination of quadrilateral and triangular meshes is the best in terms of efficiency and accuracy;

• All flow regimes, i.e., subcritical, transcritical, and supercritical flows, may be simulated simultaneously without the need for special user intervention;

• Modules to simulate on-stream structures such as weir, gate, culvert, bridge, obstruction, internal boundary, and 2D pressurized zones;

• Robust and seamless wetting-drying algorithm; and• Solved variables include water surface elevation, water depth, and depth averaged velocity. Output variables

include the above, plus Froude number and bed shear stress.
