Executive Summary

The Construction (CON) Phase of the project formally begins after construction plans, specifications, and estimates (PS&E) are submitted and authorization is granted. This phase concludes when all construction work is completed and the resulting asset is accepted by the Federal Highway Administration (if Federal funds are used) and the New Jersey Department of Transportation (NJDOT) Operations.

This phase includes the work required to advertise and award the contract, set up construction management systems and processes, mobilize for construction, execute and control the construction, complete contract work, and close out the project.

The phase is closed when all construction work and as-builts are completed, the final change order is processed, final payment is made and the records are stored. There is no further closeout work done beyond the CON Phase.


The primary objectives of the CON Phase are to execute a contract and build the project using the contract documents developed during the Final Design (FD) Phase. The project should be delivered within the approved schedule, authorized budget, and with minimal changes. Projects are to be completed in according to the quality standards described in contract documents. The work is to be accomplished without safety incident or negative environmental impact and with minimal traffic impact.


Funding for the CON Phase may involve state and/or federal funding sources. It requires funding authorizations for construction, material inspection and related costs. Depending on the project’s specific scope, funding authorizations may be needed for the construction contract, construction inspection, construction engineering, construction management and construction schedule management. Funds are also set up for contingencies.

Key Stakeholders

Completing the construction of transportation projects requires coordination with numerous internal and external stakeholders.  Major internal stakeholders include the Division of Construction Services and Materials, the Division of Project Management, the Division of Accounting and Auditing and, depending on project requirements, Subject Matter Experts (SME) in design, risk management, environmental and landscape architecture offices as well as government and community relations personnel.

Outside agencies may include the construction contractor, state and federal transportation agencies, state and federal environmental resource agencies, offices and organizations affiliated with any counties and municipalities affected by the project, the motoring public, pedestrians, and any affected residences and businesses. 

Early in the CON Phase, a pre-construction meeting is held to bring key stakeholders together to present the overall project plan and begin to address any issues and concerns. These key stakeholders include the Division of Construction Services and Materials, the contractor, and the municipalities and counties.
