Triple Constraints
What does the project development process look like?
Planning: Define the project by identifying funding options and requirements, including the neighborhoods served, anticipated impacts and benefits, mode of travel and station locations.
Environmental Review: A formal, regulated process in which Metro meets specific criteria outlined by the state and federal government in order to clear the project for construction.
Engineering: Determine the overall budget, how the project is to be built and what additional resources, like required improvements to adjacent utilities, are needed for construction and operation of the project.
Design: Define the look, shape and feel of the project to ensure that all that was planned for the project, including providing services to the neighborhoods, is delivered with minimized negative impacts and maximized benefits.
Construction: Activities may include utility relocation, development of the alignment and installation of communication systems. Operations: Implementation of the planned project. Maintenance: Ensuring Metro capital facilities maintain a state of good repair.
What are the interrelated factors?
The triple constraints of a project are scope, schedule and budget.
- Scope: The tasks required to meet the project goals. These are formed in early planning and engineering, and continue through design and construction.
- Schedule: The time for a project to reach completion. The schedule is defined in environmental review and design and can continue to change throughout construction.
- Budget: The financial constraints of a project. The budget is determined in environmental review, engineering and design.
