3. Iterative planning: Today’s right-of-way, utilities relocation, environmental protection or-
dinances, and construction codes are complex. As many as 15 agencies representing right-
of-way, local government, citizen review committees, fire department, health department,

police, utilities, zoning, land use, highway, historical preservation, environmental protection,
etc. are likely to be involved.

7.3.2 Use of Application Modules

1. Employ a separate Web site for each project, where all documents will be posted and trans-
actions will take place.
2. Employ electronic white boards to facilitate interactions and on-the-spot markups of plans
by plan reviewers and design professionals.
3. Allow automatic updates of submissions.
4. Enable field inspectors to use wireless communications tools to access project drawings

online and transmit their inspection results right away.
5. Automatically route all documents to appropriate review agencies.
6. Enable applicants to monitor the progress of reviews carried out by each agency.
The system will use application modules that can be downloaded on an applicant’s personal
computer. Modules will include the road map of the permitting process and resources needed
for permit approval. An inventory and checklist will be maintained for status and any missing
details in documents submitted. It will identify violations of air quality, water quality, fauna and

flora and adverse environmental impacts. Based on technical information submitted, computer
programs may suggest remedies and request an alternate design or construction method. The
new system will:
An education and training process for the new computer software will be required for ap-
plicants and design professionals. Agencies will suggest ways and means to iron out any inherent

procedural difficulties. It will save man-hours for both applicants and agency officials and will

ensure an early start of construction.
7.3.3 Project Management Aspects for Widening or Replacement

All major repairs or retrofit will fall under general rehabilitation as distinct from replace-
ment. These guidelines are intended to be used during project scoping. The following important
factors need to be addressed for any superstructure and substructure rehabilitation issues:
1. Funding and cost.
2. Development of rehabilitation schemes.
