GUIDING PRINCIPLES
Complete the Harry W. Nice Bridge replacement project consistent with:
The context of MDTA’s statewide program and other future system priorities
Project Goals and Objectives (see next page)
Purpose & Need from Finding of No Significant Impact (FONSI)
19
PROJECT GOALS AND OBJECTIVES
Continue to maintain the existing 70+ year old bridge in Fair to Satisfactory Condition.
Undertake all pre-construction activities and eventual construction for the replacement structure and removal of the existing structure in an environmentally sensitive manner and consistent with the approved NEPA documents and applicable permits
20
PROJECT GOALS & OBJECTIVES (CONT’D.)
Design, construct, operate and maintain a cost-effective replacement structure that provides a safe, durable and efficient new Nice Bridge for at least 100 years, under the most financially advantageous toll structure that provides best-value for MDTA and our customers.

“Lessons Learned” Workshops (Cont’d.)
24
Value Adding Examples:
Procurement
• All panelists used a fixed price contract. Suggested to
advise the proposers of the project budget, so that the
award is based on the scope for the price in best value
procurement
Cost Estimates
• Risk assessments should be used to determine appropriate
contingencies. Contingencies should be reported in the
Financial Plan, and it is appropriate to include a
reasonable allowance item in the contract.
“Lessons Learned” Workshops (Cont’d.)
25
Value Adding Examples:
General Design & Construction
• Tie the materials acceptance criteria to the corrosion plan,
so that the project service life Design assumptions are tied
to actual Construction performance.
Bridge Types and Aesthetics
• Cable stay commonly used today for projects with main
span lengths 650' to 1,500'(+). The panel believed that
cable stay/extradose bridges are most economical type
for spans ≥ 500‘.
“Lessons Learned” Workshops (Cont’d.)
26
Value Adding Examples:
Construction
• Be careful with the provisions for weather delays. The risk
allocation needs to be clearly spelled out to prevent
claims.
Design-Build Quality
• Require Developer to include an independent road
safety inspection with punchlist corrections prior to
acceptance.
“Lessons Learned” Workshops (Cont’d.)
27
Value Adding Examples:
P3 Projects
• P3’s are not only used as a funding mechanism, but more
importantly to get fixed long-term costs, transfer risk, gain
innovation and efficiencies, and provide a multi-year
“warranty” through the concession period. Delivery
technique most focused on life-cycle costs and prevents
deferring maintenance.
Milestone Payments
• The panel recommended to use milestone payments for
mega-projects, while holding a significant final payment
to push for project completion.
“Lessons Learned” Workshops (Cont’d.)
28
Value Adding Examples:
Operations and Maintenance
• Handback requirements in O&M concessions are often
overly focused on pavement and bridges, while not
appropriately addressing barriers, ancillary structures, etc.
Project Delivery Selection
• Value for Money analysis is only one tool to assist with
selecting project delivery. The key factors that influence
the delivery decision should be: Finance, Risk, Public
Value, & Schedule.
PROJECT DELIVERY OPTIONS
DBB: Design-Bid-Build
CM/GC: Construction Manager/General Contractor
DB: Design-Build
DBOM: Design-Build Operate Maintain
P3/ Public-Private Partnership / DBFOM: Design-Build-Finance-Operate-and-Maintain

CONCEPTUAL WORKFLOW CHART

Evaluation of Delivery/Procurement Options
Develop Risk Register • identify • assess • assign
T&R Projections • toll policy decision (timing) • existing conditions • economics, demographics • traffic models • T&R projections • strengths/risks of projections Risk Workshop(s)
(includes Market Soundings)
Financial Analysis • Public Options • Private Options
Value for Money Analysis
Select Project Delivery Method (includes additional risk and delivery method workshops)
Prepare Financial and Project Management Plans
Federal Funding Analysis
Cost Estimates • construction • O&M • capital expenditures • timing escalation
Engineering/Bridge Concepts • toll policy decision (cash) • channel clearances • profile, typical section • safety, levels of service
RISK BASED PROJECT APPROACH Project Delivery method decision driven by evaluating the
party/parties in the best position to manage risks.
Typically the assuming party has a level of control over factors that affect risks and are positioned to:
minimize the adverse impacts of the risk on themselves, and
minimize the adverse impacts of the risk on others
31
PRELIMINARY ENGINEERING
TASKS UNDERWAY Comprehensive “due diligence” activities
Engineering Concepts and Cost Estimates
Traffic/Revenue Study
Advance Coordination with Stakeholders

Main Span Horizontal Clearance Reduction:
Existing Clearance = 700 feet Existing Clearance w/ sufficient Vert. Clearance = 480 feet
USCG Bridge Guide Clearance (Potomac River) = 250 feet Upstream bridges = 175 feet (max.) Downstream buoys = 450 feet
* Objective: Proposed bridge safely meets the needs of all stakeholders.

Geophysical investigation complete. Over 1,000+ anomalies detected.
Approximately 50 anomalies dive inspected; none indicated UXO.
Finding construction, fishing, & vessel debris.
Further diving planned for Spring 2015 to investigate another 100-125 anomalies.
Navy to complete more sophisticated Geophysical investigation Spring 2015.

Geotechnical Data Collection: Permits received for boring program.
Contract NB2849 for subsurface exploration
and laboratory testing is scheduled to Advertise Spring 2015.
JPA and NFMS coordination ongoing for foundation testing program. Working with Tappan Zee team for NFMS coordination
Contract NB2856 for foundation system testing is planned to Advertise Spring 2016, following receipt of boring data.
RIGHT-OF-WAY TASKS UNDERWAY 1. Developing ROW Mosaics and plats
2. Acquiring properties on the Maryland side within the NEPA limits of disturbance
3. Working with Virginia to clear ROW on the VA side

FINANCIAL QUESTIONS TO BE ADDRESSED
A Range of public and private Funding Options:
Operational options will include MDTA Staff vs. Private sector operation and/or maintenance
38
FINANCIAL QUESTIONS TO BE ADDRESSED CONT’D.
Two basic Toll Collection System options [affects T&R, O&M, Capital Expenditures, and Cost Estimates]:
Toll Schedule Structure/Sensitivity Analyses and other factors
39
AET (All Electronic Tolls) ORT (Open Road Tolling + Cash)
MD 200 FMT
ENGINEERING QUESTIONS
TO BE ADDRESSED
Prescriptive vs. Performance Design Criteria
Forecast long-term traffic needs and available capacity
Use Lessons Learned, Market Soundings, and Industry meetings to help inform sizing of construction packages and quality management plan.
40
NEXT STEPS
Continue Preliminary Engineering and ROW activities
Continue Financial and Funding analysis
Determine Project Delivery Decision (Est. End of CY 2015)
Develop the Financial and Project Management Plans
Although exact timing remains TBD, and will be driven by the final decision on the funding and delivery method, the assumed time frame for the start of construction is between 2020 and 2025
