Project Overview
• $30 Million-Indefinite Quantity Contract-NAVFAC (Naval Facilities
Engineering Command )
• Utilities Design and Engineering
• Utility-repair, replacement & upgrade
• Each project had a separate “Mod”
• Transportation Projects:
– Road widening-Several corridors
– Traffic capacity analysis-Synchro
– Signal Design and ITS
Transportation Projects
• HP (Hadnot Point) Roads-Widening
– Louis Road
– Dogwood Street
– Holcomb & McHugh roundabout / traffic circle
• Piney Green Road-Widening
• Gonzalez Boulevard Extension
• Resurfacing of Streets

Resurfacing
Gonzalez Blvd Ext
HP Roads – Louis Road
• 2 existing signals• Sneads Ferry
• McHugh Blvd
• Heavy congestion
• Dogwood Street• Not a through
street today
HP Roads – Louis Road Recommendations
• Add two more signals
– Birch Street
– Dogwood Street
• Widen to three lanes
• Complete Dogwood Street• Provides new link to commissary
• FYA at 3 of 4 signalized intersections
Roundabout – McHugh at Holcomb

Roundabout – McHugh at HolcombRecommendation
Gonzalez Boulevard Extension
• New location
• Barracks under construction
• Mess hall under construction
• Would Provides link to French Creek between McHugh Blvd and Sneads Ferry Rd
• Two lane section recommended
• FYA at signalized intersection
Piney Green Road
• Alternative entrance into MCB Camp Lejeune
– Main commercial truck entrance
• Improvements at entrance control facility underway
Piney Green Road - Recommendations
• Widen to four lane section
• Add additional exiting lane at entrance control facility
• Non typical widening to avoid impacts to adjacent land uses
• Status: Piney Green was bid as an option which NAVFAC has not awarded yet.
Specs Intact
• Does not include signal specifications
– Signal specifications were added as needed to reflect NCDOT standards
• Other standards also must be included
– ASTM
– NEC
– NCDOT
• Example:
– Instead of referring to the NCDOT standards for foundations, detailed specifications were listed for excavation, concrete pouring, curing etc—Mast arm poles
Charettes
• Intense 2 day Design Charettes (20-25% design stage) between the Client and the Consultant
– First day:
• Initial discussion/Powerpoint presentation regarding the project
• Consultant presents initial design and recommendations/alignment options
• Client provides feedback/direction
• Consultant captures the feedback using “smart boards”
• Consultant analyzes the changes on that evening
– Second day:
• Consultant updates/modifies the presentation
• Consultant gets the “buy-in” on the design concept
• Client approves the concept
Challenges
• Flooding
• Very flat and adjacent to the ocean
• Steam vaults
• Vehicular types
• Cars
• Military trucks (MRAPs) - 30+ tons weight
• Tanks
• Trains
• Base access
• Projects in parallel--Review process
• High concentration of young drivers
Challenges Continued
• Vehicular patterns
• Everyone arrives at 6AM and leaves at 3PM
• No range for the peaks-It happens at once
• Considered reversible lanes:
– Piney Green
– 80/20 Traffic split
– Dropped because of operational challenges
Pleasant Surprises of Working at MCB Lejeune
• No ROW constraints as all Military property
• Traffic very predictable, congestion early AM, lunch and late afternoon
• Drivers stopping and allowing us to continue working
• No speeding drivers
• Review process was very formal
• All utilities were owned by the Military-Coordination was easier
