The goal of this project is to return the cultural landscapes and trail system to good condition while addressing chronic drainage issues. All elements of this project shall be completed by October 15, 2024.

1.2 LOCATION

This project is located at Minute Man National Historical Park (MIMA).

A seven-mile linear park with four distinct units, the Minute Man NHP spans three towns -- Concord, Lincoln, and Lexington, Massachusetts -- and attracts more than one million visitors a year. The park’s mission is to preserve the historic sites, structures, properties, and landscapes associated with the opening battles of the American Revolution. The park also preserves resources related to America’s literary tradition, including The Wayside, 3170529 RFP-TRAILS 09/09/2022 | Page 7 of 96 home of three nineteenth century American authors. The park maintains some 200 assets, including about 1,000 acres of maintained landscape and twelve witness structures that were present at the time of the Battles of Lexington and Concord on April 19, 1775.

Work included in this project lies within two of the four units which make up the park: the Battle Road and North Bridge.

1.3 BACKGROUND

In 2025, MIMA will commemorate the 250th anniversary of the opening battle of the Revolutionary War with numerous special events. To prepare for these commemorations, the National Park Service has prioritized work which will improve the condition of park amenities and assets and create a safer environment for park visitors and staff.

The Great American Outdoors Act (GAOA) has provided funds necessary to complete several projects within the park. These projects will address deferred maintenance issues in park environs and bring several residential properties into a condition which will allow rental and collection of needed funds for future park maintenance.

Concurrent with this RFP, the park has solicited work which will repair 18 structures over 15 sites for leasing and park ancillary use. The park will also address wayfinding and interpretive signage along the trail and conservation of the park’s monuments and statues through separate projects. The work within this RFP will require coordination with contractors or crews during construction at various structures as well as during the repair or installation of signage along the trail.

Due to the work’s proximity to designated wetlands and a complicated pattern of ownership and control, the work within this project will require oversight by local conservation commissions and coordination with various municipalities. The sensitive archeological nature of the park will require coordination with NPS archeological staff, and all work will be completed through consultation and agreement with state and local preservation organizations.

Fast track construction: 100% Complete DB Construction Documents affecting work to be constructed.

Currently, both the Reroute of Battle Road (PMIS 170863) and Boardwalk Repairs (PMIS 322882) are approved and ready to begin construction. Construction may begin as soon as possible for these parts of the project.

Purpose: Project schedule ensures adequate planning, coordinating, scheduling, and reporting of DB Contractor’s design and construction activities. Project schedule will assist DB Contractor and Contracting Officer to monitor work progress, evaluate proposed changes, and process DB Contractor's monthly progress payment requests.

Schedule Development: Project schedule shall cover entire contract period. Late finish date is same as contract’s established completion date.

DB Contractor shall use Critical Path Method (CPM) with limited use of lead or lag durations between schedule activities. DB Contractor's project schedule shall consist of procurement activities (including mobilization, submittal, and fabrication and delivery of key and long-lead procurement items) and construction activities.

DB Contractor's project schedule shall consist of, but not be limited to, the following for each activity:

Identify activities and numbers numerically (maximum 5-digit). Number activities in increments of 10.

Concisely describe work represented by activity (maximum 48 characters). Avoid using non-standard abbreviations. Limit work related to each activity to one work trade.

Activity duration shall be in whole working days with maximum duration 15 work days each, unless otherwise approved by Contracting Officer, except for non-construction activities including mobilization, shop drawing and sample submittals, fabrication of materials, delivery of materials and equipment, and concrete curing.

DB Contractor shall ensure project schedule includes own work and Subcontractor work.

3170529 RFP-TRAILS 09/09/2022 | Page 18 of 96

Project schedule shall show sequence and interdependence of activities required for complete performance of work and shall be cost and resource loaded. DB Contractor shall ensure work sequences are logical and project schedule shows a coordinated work plan. Proposed durations assigned to each activity shall be DB Contractor's best estimate of time required to complete activity, considering scope and resources planned. Resource loading of each activity shall list personnel by labor category and equipment type, and capacity proposed to complete activity in duration shown. Include permit requirements and constraints. Schedule shall include possible suspension of activity or closures related to Park events, as well as closures necessary for construction. Consider and include seasonal weather conditions in planning and scheduling of work influenced by high or low ambient temperatures and wind and/or precipitation, to ensure completion of work within contract time.

Project Schedule Updates

Monthly updates: Monthly updates of project schedule shall be an integral part and basic element of estimate upon which progress payments shall be made under this contract. If, in judgment of Contracting Officer, DB Contractor fails or refuses to provide schedule of values and complete schedule update or revision as specified hereinafter, DB Contractor shall be deemed to have not provided required information upon which progress payment may be made and shall be subject to retainage of a portion of the payment.

Narrative

Include in report:

Brief description actual progress made during update period Actual and potential delaying activities Impediments to progress Issues related to inclement weather Progress toward established milestones.

Upcoming partial or full closures of park facilities Anticipated timing of reopening of park facilities Project float Brief description of work anticipated to be performed in next month Identify minor revisions to schedule for evaluation and accepted or rejected

As work progresses, indicate Actual Completion percentage for each activity. If schedule update shows late finish date after contract completion date, at a minimum, include the following in narrative with submission:

Known delays Actions taken to get back on schedule Pending modifications Impediments or constraints affecting progress

3170529 RFP-TRAILS 09/09/2022 | Page 19 of 96

Progress Payments: Update currently accepted construction schedule monthly. If DB Contractor fails to provide monthly updates or revisions to currently accepted construction schedule, a portion of monthly payment may be retained until updates/revisions made.

Time Impact Analysis for Contract Modifications, Changes, Delays, and Contractor Requests Requirements: When contract modifications or changes are initiated, delays are experienced, or DB Contractor revises project schedule, DB Contractor shall submit to Contracting Officer a written time impact analysis illustrating influence of each modification, change, delay, or DB Contractor’s request on the contract time.

Time Extensions: Activity delays shall not automatically mean an extension of contract time is warranted or due to DB Contractor. It is possible that modification, change, or delay will not affect existing critical activities or cause non-critical activities to become critical. A modification, change, or delay may result in only absorbing a part of available total float that may exist within an activity chain of the project schedule, thereby not effecting the contract time. Time extensions will be granted according with terms of contract.

Float: Float is not for exclusive use or benefit for NPS or DB Contractor. Extension of contract time is granted only to extent the equitable time adjustments to activity or activities affected by modification, change, or delay exceeds total (positive or zero) float available on a particular activity.
