PROJECT SCOPE

1.0 BACKGROUND

The Old Fort Rosalie Gift Shop is the only remaining remnant of a 1939 tourist attraction constructed on the original site of the 18th-century French Fort Rosalie. The death of its entrepreneur-developer during World War II brought an end to the operation of this attraction, and the site has been home to a variety of functions since that time. This structure is best known locally at the 17-year home of Fat Mama’s Tamales prior to construction of their new location further down Canal Street.

Though historic photos show that the structure’s roof was originally wood shingles, the existing metal roof has been in place for many years.

Natchez NHP plans call for the structure to be rehabilitated for visitor services use as a venue for robust exhibits on the north end of the Fort Rosalie site. The NPS has completed HABS drawings and a Historic Structure Report for the building.

2.1.5 Project Schedule

General: The Contractor shall provide a written summary construction schedule with important milestones before the pre-construction meeting or any work begins.

Purpose: The purpose of the project schedule is to ensure adequate planning, coordination, scheduling, and reporting during execution of the work of the contract.

The project schedule will assist the contractor and the Contracting Officer in monitoring the progress of the work and evaluating proposed changes.

The project schedule shall consist of procurement activities (including mobilization, submittal, and the delivery of key and long-lead procurement items) and construction activities.

The project schedule shall consist of, but not be limited to, the following for each activity:

· Concise description of the work represented by the activity. Avoid the use of non-standard abbreviations. The work related to each activity shall be limited to one work trade.

· Activity duration in whole working days including non-construction activities such as mobilization, shop drawing and sample submittals, delivery of materials and equipment.

In developing the project schedule, ensure that subcontractor work at all tiers, as well as contractor’s own work, is included in the project schedule.

Proposed durations assigned to each activity shall be the contractor's best estimate of time required to complete the activity considering the scope and resources planned for the activity.

Seasonal weather conditions shall be considered and included in the planning and scheduling of all work influenced by high or low ambient temperatures, wind and/or precipitation to ensure completion of all work within the contract time.

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

Time Extensions: Activity delays shall not automatically mean that an extension of the contract time is warranted or due the contractor. It is possible that a 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 the available total float that may exist within an activity chain of the project schedule, thereby not causing any effect on the contract time. Time extensions will be granted in accordance with the terms of the contract.

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

2.2 Environmental Requirements

Environmentally friendly products shall be used where possible. Conduct work operations with sensitivity to the natural surroundings.

Select materials that can be reused or recycled or materials with a significant percentage of recycled content. Avoid recycled content materials that are difficult to recycle. Use products with an extended lifecycle.

· Waste Management Goals: Employ processes that ensure the generation of as little waste as possible due to over-packaging, error, poor planning, breakage, mishandling, contamination, or other factors. 0f the inevitable waste that is generated, as many of the waste materials as economically feasible shall be reused, salvaged, or recycled. Waste disposal in landfills shall be minimized.

· Materials: Use resources efficiently. Select materials and use construction practices that achieve the most efficient use of resources and materials.

Recycling is not a requirement of this project. Local recycling is unavailable. All material unsuitable for recycling must be disposed of, in a legal manner, at public or private dumping areas outside the park.
