GATE 308184

SECTION 01 11 00 - SUMMARY OF WORK

PART 1 - GENERAL

1.1 SUMMARY

A. Section includes the following:

1. Work Covered by Contract Documents

2. Construction Contractor Use of Site

3. Public Use of Site

4. Occupancy Requirements for Buildings

5. Conduct of Operations

6. Work Restrictions

7. Resource Preservation

B. Project Location: Fort Tompkins, a part of Fort Wadsworth, Gateway NRA Staten Island Unit, Staten

Island, NY.

C. Project Background: Fort Tompkins Quadrangle (1859 – 1876) was individually listed in the

National Register of Historic Places in 1974, and is also identified as a fundamental contributing structure to the proposed Fort Wadsworth National Register Historic District. It is in current use for both park operations and visitor use. Water infiltration through the earthen-filled roof structure of

Fort Tompkins has been an on-going problem for many years. With the increased frequency and intensity of rain events due to climate change, it is critical to begin a comprehensive approach to the waterproofing and repair of the earthen roof structure of Fort Tompkins, to reduce water infiltration and protect the historic resource from further material deterioration or loss of important character-defining features.

D. Be advised, Gateway National Recreation Area (GATE) is home to former active military sites and there could be unexploded ordnance (UXO) contained within the ground and/or waters of the park. If a UXO is discovered, extreme caution is warranted, and it should be treated as a live/active munition until proven otherwise. If a UXO is discovered or suspected, immediately cease operations and notify the GATE Dispatch Center (24/7) by calling 718-354-4700. Advise all personnel to clear the area and do not touch the item(s). Emergency response officials will respond and investigate.

E. The Work consists of:

1. The project is Phase 1 of the earthen roof restoration at Fort Tompkins. Fort Tompkins is a Third Period Fortification dating to the 1850s. Its roof consists of earthen fill over masonry vault structures with a depth of fill ranging from 3’ to 20’. There is an original roof drainage system consisting of a culvert and leader at each valley between the vaults.

The function of this system is highly compromised, as is the overall waterproofing system, allowing significant water infiltration into the structure of the fort. This project will

GATE 308184 01 11 00 - 2

investigate and address one bay at the south range of the fort, and undertake additional probes in other areas of the fort. All work shall be performed in accordance with the Secretary of the Interior's Standard for the Treatment of Historic Properties

2. Work includes:

a. Provide archaeological monitoring and investigation as work progresses.

b. Hand-excavate and remove earthen fill above the masonry structure, with archaeological investigation of the fill.

It shall include the dates in the contract, phases, milestones, occupancies, holidays, weather consideration, a critical path, and the requirements of this section.

1.2 DEFINITIONS

A. Activity: A discrete part of a project identified for planning, scheduling, monitoring, and controlling the construction project. Activities included in a construction schedule consume time and resources.

1. Critical activities are activities on the critical path. They start and finish on the planned early start and finish times.

2. Predecessor Activity: An activity that precedes another activity in the network.

3. Successor Activity: An activity that follows another activity in the network.

B. Cost Loading: Allocation of the Schedule of Values for completion of an activity as scheduled.

The sum of costs for all activities must equal the total Contract Sum, unless otherwise approved by the Contracting Officer.

C. Critical Path Method (CPM): Method of planning and scheduling a construction project where activities are arranged based on activity relationships. Network calculations determine when activities can be performed and the critical path of Project.

D. Critical Path: Longest connected chain of interdependent activities through the network schedule that establishes minimum overall Project duration and contains no float.

E. Float: Measure of leeway in starting and completing an activity.

GATE 308184 01 32 16 - 2
