Each Surety executing this instrument agrees that its obligation is not impaired by any extension(s) of the time for acceptance of the bid that the Principal may grant to the Government.

SCOPE OF WORK

A.1 Description of Project

The 18-mile Mount Vernon Trail (MVT) is a paved, multi-use trail corridor stretching from George Washington’s Mount Vernon Estate to Theodore Roosevelt Island, linking Fairfax County and the City of Alexandria, to Arlington County and major Potomac River bridge crossings into the District of Columbia. The MVT is a popular recreation resource and a critical regional transportation connection. The trail hosts over one million pedestrians and bicyclists annually. During peak periods, the MVT north of Alexandria is one of the most heavily used multi-use trails in the country. The National Park Service originally constructed the MVT in the 1970s and 1980s. The trail is relatively narrow by modern standards and characterized by meandering curves, timber bridges, and in some areas, dense vegetation.

The trail is a critical regional transportation connection and recreational amenity set within the cultural landscape of the planned design of the Mount Vernon Memorial Highway and the George Washington Memorial Parkway (MVMH/GWMP). This project may affect the character of the landscape which is a contributing feature to the National Register of Historic Places significance of the MVMH/GWMP.

Many of the built facilities along the MVT need immediate attention. The bridges, trail tread (condition and width), trail alignment, drainage, signage, and trailhead features (i.e. benches, drinking fountains, bike racks, etc.) are all in need of varying levels of rehabilitation due to their age and deferred maintenance.

This project is intended to address deferred maintenance, accommodate changes in use, improve accessibility, functionality, longevity, and safety of the trail along the northern section of the MVT. The approximate limits of construction are from the City of Alexandria (Milepost 11.0) to the northern terminus at Theodore Roosevelt Island (Milepost 17.5).

The project is located in Arlington County and the City of Alexandria, Virginia and the District of Columbia, Washington, D.C.

The project also includes preparing any required documents for design waivers and exceptions and obtaining all permits required to construct the project.

The work is split into bid schedules as follows:

Base Contract (Schedule A):

The base contract is for the design of the Mount Vernon Trail reconstruction and construction of the Mount Vernon Trail in Arlington County and the City of Alexandria, Virginia.

Option 1 (Schedule B):

Option 1 contract is for the construction of the Mount Vernon Trail on Columbia Island in the District of Columbia, Washington, D.C.

The project design shall be completed and approved by the Contracting Officer (CO) prior to construction. Temporary traffic control, erosion sediment control, and other non-earth disturbing measures can be implemented in advance of the start of construction to facilitate project design, fieldwork, and time of year restrictions such as survey, staking, tree cutting, and design submittals.

A.2. Roadway Design

A.2.a. General

In accordance with the National Environmental Policy Act (NEPA), the National Park Service (NPS) and Federal Highway Administration (FHWA) are preparing an analysis of potential environmental effects and corresponding regulatory consultations. The Contractor shall design and construct the project within the Limits of Disturbance (LOD) described in the NEPA documentation. The Contractor has flexibility to produce benefits or savings to FHWA and/or the Contractor, without impairing essential project functions and characteristics such as safety, maintainability, environmental protection, drainage, and other permitted constraints.

Develop a horizontal alignment, vertical profile, and bridge design conforming to applicable design codes and using the provided Conceptual Plans as a guide to commencing the design.

Design the Project using CAD files format compatible with OpenRoads Designer (ORD) or OpenSite Designer software.

A.2.b. Scope of Work

Site Access. The primary construction access to the project site is the Northbound lanes of the George Washington Memorial Parkway (GWMP). Additionally, there is limited space for staging throughout the project site. Staging areas can be located in the parking lots (Columbia Island Marina, Gravelly Point, and Daingerfield Island) adjacent to the Mount Vernon Trail (MVT) within the project limits and/or at the southern end of the Arlington Memorial Bridge (AMB). Localized “off-trail” staging areas will be permitted outside of any sensitive archaeological and environmental sites. Develop an Access Plan that describes the means to stage and store equipment, materials, etc. at the project site. Describe the means and methods that will be required to access the site and construct the proposed bridges. Propose methods of access that minimizes adverse impacts to environmental resources.
