1.3 Location

This project is located off New Dorp Lane, on the eastern shore of Staten Island, New York. The historic, former Seaplane Hangar #38 anchors the southeast corner of the Miller Field Unit of

Gateway National Recreational Area.

1.4 Background

Miller Field was established prior to World War I as part of a system of aerial coast defenses for

New York City. An early aviation building, Seaplane Hangar 38 was constructed at Miller Field in 1920 for the U.S. Army and is the sole survivor of a hangar group and base comprising approximately 40 buildings. Hangar 38 remains significant as one of the last extant examples of its type remaining on the eastern seaboard.

On October 29, 2012, Superstorm Sandy inundated Miller Field, bringing salt water, debris, and wave action to the Seaplane Hangar 38 and the rest of the site, triggering the need for mitigation of life-safety hazards and protection of the historic resource. Carrying contaminated mud and sludge into the hangar bays, the storm surge damaged features and exacerbated ongoing deterioration of interior and exterior finishes. The park is currently in the recovery phase and has been methodically repairing and rebuilding, making use of funds appropriated via the Sandy Recovery

Improvement Act. The purpose of this project is to mitigate hazards, increase resiliency and reduce the risk of damage from future flooding.

1.5 Description

Consisting of two adjacent hangar bays, the original Seaplane Hangar 38 building was extensively renovated in 1939 as a federal Works Progress Administration (WPA) project; the

WPA work included a two-story addition on the west and one-story additions on the south and east sides of the hangar. The two-story office/support facilities wing is reinforced concrete-framed with masonry infill, while the one-story utility, shop and support spaces are predominantly constructed of concrete piers and walls supporting wood roof framing.

The extant two-bay hangar structure is characterized by riveted trusses built up from steel angles and clear-spanning 110 feet in the east-west direction, over each hangar bay. Roof trusses and supporting columns are spaced 20 feet on center in the north-south direction.

Supporting columns are built up from four riveted steel angles and a web plate, all encased in terra cotta tile and stucco finishes. At each hangar bay, a pair of doubled roof truss added to the original hangar structure span the north-facing hangar door opening; tying together an assembly of pylons, pulleys cables and counterweights, the inner truss pair carries the massive hangar doors and the original trusses supports the gable end and roof deck above.

In general terms, the project entails removal of all additions and all original and subsequent enclosure elements, fixtures, finishes and appurtenances, leaving only the original structural steel framing and corrugated steel roof decking in place, followed by structural repairs, lateral reinforcement, surface preparation and application of a high-performance coating throughout, in order to create a stabilized steel “skeleton” with retained roof decking.

Include permit requirements and constraints.

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.

Project Schedule Updates

Monthly updates: The monthly updating of the project schedule shall be an integral part and basic element of the estimate upon which progress payments shall be made under this contract.

If, in the judgment of the Contracting Officer, the DBC fails or refuses to provide a schedule of values and a complete schedule update or revision as specified hereinafter, the DBC shall be deemed to have not provided the required information upon which the progress payment may be made, and shall be subject to retainage of a portion of the payment.

Time Impact Analysis for Contract Modifications, Changes, Delays, and Contractor

Requests Requirements: When contract modifications or changes are initiated, delays are experienced, or the DBC desires to revise the project schedule, the DBC shall submit to the

Contracting Officer a written time impact analysis illustrating the influence of each modification, change, delay, or DBC 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 DBC. 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

DBC. 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.

Modification Proposal Pricing Requirements

General:

1. Your proposal must be received in the format and within the time frame specified in the

Request for Proposal letter. Costs or delays resulting from failure of contractor to submit within the time frame specified will not be compensable.

2. The proposal must be detailed with itemized lists of equipment, materials, labor, production rates, overhead, profit, and bond markup for each item. Labor costs must be itemized by craft and hourly rate, including Fringe Benefits and Labor Burden. If the costs of

Fringe Benefits and Labor Burden are not itemized, it is assumed that that they are included in the hourly rate shown, or contractor is not requesting reimbursement. Contractor may utilize the government provided Contractor Estimate Form, or their own form, provided that it contains the same information and level of detail as the Gov’t provided form.

3. Requests for extensions of contract time as a result of this change must be justified with a

Time Impact Analysis (TIA). Refer to Division 01 Specification, “Construction Schedule”, for time impact analysis requirements. TIA and associated costs must be received with the proposal by the date shown within the Request for Proposal letter. Contractor’s failure to submit within the specified time frame will be construed as the Contractor waiving the right for additional time and no time extension will be allowed.

4. All supporting documentation used to justify the proposed modification will be made available to the Contracting Officer upon request.

5. Contractor must review and approve all subcontractor/supplier pricing in detail for proper format, scope, production rates, and pricing prior to submission to the NPS. All delay costs associated with not reviewing and approving subcontractor/supplier pricing will be borne by the Contractor.

6. All pricing and production rates within the estimate must be based on fair and reasonable pricing and cannot include built-in contingency.

Labor:

1. Contractor shall estimate the cost of labor by itemizing each craft involved, indicating worker hourly rate (base rate + labor burden + fringe benefits) for each and itemizing the hours required for each craft that will be directly engaged in modification work. Any work proposed that will require overtime work or premium pay shall be itemized separately. All rates shall be in accordance with the Davis-Bacon Act as incorporated herein. Labor Burden may include payroll taxes, Social Security, unemployment insurances, workers compensation insurance, FICA, FUTA, and other direct costs resulting from Federal, State or local laws.

2. Itemize labor costs for equipment operators separate from equipment costs.

3. The labor cost for foremen shall only be costs for related work required for the modification.

Materials:

1. The estimated cost for materials shall include quotes from multiple sources. Material prices must include all applicable fees and credits, including but not limited to, sales tax, freight and delivery charges, and tax rebates.

2. No markup shall be applied to any material provided by the NPS.

Equipment:

1. Equipment used for the project must be appropriately sized for the work being performed.

2. Do not include costs for “miscellaneous tools and equipment”, in your proposal for a replacement value of $500 or less. Costs shown in excess of $500 must be broken out separately.

3. Regardless of ownership, the rates to be used in determining equipment rental costs shall be the lowest cost from one of the following sources:

a. U.S. Army Corps of Engineers , Ownership and Operating Expense Schedule (use latest edition and applicable region)

b. Construction Blue Book

c. Local equipment rental rates, documented by actual invoice charges, or itemized vendor quotes.

4. The estimated equipment rates shall include the operating costs of all fuel, oil, lubrication, supplies, small tools, necessary attachments, ground engaging components, tires

& tracks, routine repairs and maintenance (cost of major repair and overhaul is not allowed per FAR 31.105(d)(2)), depreciation, storage, insurance, and all incidentals. Mobilization, if applicable, may be included for equipment solely used on the modification work but must be listed separately.

5. Estimate the full rate for equipment only for the duration that the equipment will be utilized to accomplish the work of the modification.

6. Standby unit rates used are to be in accordance with paragraph 1.3, D, 2, above. If the US

Army Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then ½ of the equipment costs minus any operating costs, major repair and overhaul will be accepted.

7. If equipment is in standby mode due solely to a documented NPS delay, the established standby rate shall apply from the first day of the delay.

8. Equipment that is not used and on the jobsite for up to five consecutive days may be classified at standby rates, provided that the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work.

Equipment that is still on the jobsite but not in use after five consecutive days will not be considered in the modification pricing.

9. Requests for compensation for equipment stand by time must be justified, documented and itemized separately.

10. The estimated timeframe (daily, weekly, monthly) for use of the equipment must reflect the lowest cost to the Government.

Establishment of Overhead and Profit Procedures:

1. Home Office Overhead and Profit (OH&P) shall be applied to direct costs only. Profit shall not be applied to overhead amounts; and overhead shall not be applied to profit.

Home office overhead shall contain only allowable, allocable, and reasonable costs per the contract documents and FAR Part 31. Profit percentages are based on risk factors found in FAR Part 31 which have been applied to the specific type of work included in this project. Negotiated rates shall not exceed the following percentages for OH&P for contractor self-performed work:

Overhead………………10%

Profit………………..…8.0%

2. Total aggregate limit of markup (OH&P) for contractor and subcontractors on modification work shall not exceed 25%. The NPS will not be responsible for allocation of percentages between contractor and subcontractors at any tier.

3. If contractors form a partnership, than the partnership may only receive home office overhead and profit in the same amount as an individual contractor (refer to par 1.3,E,1 above). It is the responsibility of the partners to decide on the division of revenue.

4. Combined Increases and Decreases: On proposals involving both increases and decreases in the Contract Price, the overhead and profit mark-ups are required on the net increases and deducted on net decreases.

5. At no time can profit be calculated on Overhead or itself, it must be calculated on direct costs of work only.

2.2.2 Environmental and Sustainability Requirements for Design

The National Park Service has established environmental and sustainability requirements for the project. Notify the CO if conflicts arise between performance of the work and environmental and sustainability requirements. The National Park Service does not intend to limit alternative means of achieving these requirements.

Specific sustainability requirements for design may be found in Part 3, Performance

Requirements, of this document and the NPS Project Sustainability Checklist, http://www.nps.gov/dscw/publicforms.htm#psc. Complete this checklist by concisely explaining how each credit/requirement will be met.

2.3 Construction Requirements

2.3.1 Environmental and Sustainability Requirements

Specific sustainability requirements generated in design will dictate more stringent environmental requirements for this project. Refer to part 3, Performance Requirements, of this document and the NPS Project Sustainability Checklist. The following are general requirements:

Air: Employ construction practices that minimize dust production and combustion byproducts.

Water: Avoid materials that can leach toxic chemicals into the ground water. Do not allow toxic chemicals to enter sewers or storm drains.

Soil: Protect against erosion and topsoil depletion.

Habitats: Protect natural habitats and ecological systems on facility site.

Noise: Minimize noise generation during construction. Operate power equipment in accordance with local noise restrictions.

Waste Management: Employ processes that ensure the generation of as little waste as possible. Waste disposal in landfills shall be minimized. Recycling is a requirement of this project. Specific recycling goals were established in the NPS Project Sustainability

Checklist. All material unsuitable for recycling must be disposed of, in a legal manner, at public or private dumping areas outside the park.

All material unsuitable for recycling must be disposed of, in a legal manner, at public or private dumping areas outside the park.

The DBC shall designate an on-site party (or parties) responsible for instructing workers and overseeing the environmental requirements of this project. Distribute copies of the environmental requirements to the Job Site Foreman and each Subcontractor.

http://www.nps.gov/dscw/publicforms.htm#psc

Storm Water Pollution Prevention Plan (SWPPP) or Under-An-Acre Pollution Prevention Plan

(UPPP): Plan shall describe pollution prevention control methods at Contractor staging areas, material storage areas, hazardous material abatement areas, etc.

Waste Management Plan: Prior to the scheduled Preconstruction meeting, the Contractor shall submit a draft Waste Management Plan to the Contracting Officer for approval. Develop and implement in accordance with ASTM E1609 and as required in the contract documents. The plan shall include (but not be limited to) the following:

List of the recycling facilities, reuse facilities, municipal solid waste landfills, and other disposal area(s) to be used. Include name, location, and phone number.

List of materials that cannot be recycled or reused with explanation or justification.

Storage and collection methods of waste and recyclables, handling procedures, and means of keeping recyclables free of contamination.

Revise and resubmit Plan as required by the Contracting Officer. Approval of the

Contractor’s Plan will not relieve the Contractor of responsibility for compliance with applicable environmental regulations.

Prior to the commencement of the Work, schedule and conduct a meeting with the Contracting

Officer to discuss the proposed Waste Management Plan and to develop mutual understanding relative to details of environmental protection.

Minimize Construction Impacts

The following mitigation measures shall be implemented to minimize the impacts of construction activities:

Soil Erosion

Protect against erosion and topsoil depletion. Storm Water Pollution Prevention Plan / Under-

An-Acre Pollution Prevention Plan required.

Air and Water Pollution Control

Air quality impacts are expected to be temporary and localized. To minimize these impacts, the following actions shall be taken:

To reduce tailpipe emissions, construction equipment shall not be left idling any longer than is necessary for safety and mechanical reasons.

To reduce construction dust, water shall be applied to problem areas. Equipment shall be limited to the fenced project area to minimize soil disturbance and dust generation.

Take all necessary reasonable measures to reduce air and water pollution by any material or equipment used during construction. Keep volatile wastes in covered containers.

2.3.2 Schedule of Values

After contract award and before the Design Meeting, submit a schedule of dollar values based on the Contract Price Schedule. Breakdown each lump-sum item into component parts of design deliverables or construction work for which progress payments may be requested. The total costs for the component parts of work shall equal the contract line item amount for that lump-sum item. The Contracting Officer may request data to verify accuracy of dollar values. Include mobilization, general condition costs, overhead and profit in the total dollar value of unit price items and in the component parts of work for each lump-sum item, as described below. Do not include mobilization, general condition costs, overhead or profit as a separate item.

Do not break down unit price items. Use only the contract line item amount for unit price items.

The total cost of all items shall equal the contract sum. The Schedule of Values will form the basis for progress payments.

An acceptable Schedule of Values shall be agreed upon by the Contractor and Contracting

Officer before the first progress payment is processed. A cost loaded project schedule is an acceptable substitute for a schedule of values.

2.3.3 Construction Support

Staging Areas

Construction staging sites will be limited to the smallest feasible area and located on the concrete apron adjacent to Hangar 38. Staging areas must be adequately fenced for public safety and security. Ground disturbance and site management will be carefully controlled to prevent undue damage to vegetation, soils, and archeological resources and to minimize air, water, soil, and noise pollution.

All staging areas shall be returned to pre-construction conditions once construction is complete.

Standards for this, and methods for determining when the standards are met, shall be developed in consultation with the CO.

Construction access shall be via New Dorp Lane at Cedar Grove Avenue.

Structures: Trailers, Storage, Field Offices, Staging Area and Sheds: Location to be approved by the Contracting Officer.

DBC's Field Office: Field office shall be structurally sound construction, and weather tight. The location will be determined by NPS prior to issuing a Start Work Notice.

Storage Sheds: If used, provide weather tight sheds or other covered facilities for storage of materials subject to weather damage.

If used, all temporary water, sewer, sanitary facilities and electric utilities, shall be completely removed upon project completion. Remove temporary utility connections.

The location of the Staging Area for construction equipment will require CO approval.

Construction Camp: Establishment of a construction camp will not be permitted.

Construction Zones

Construction zones shall be fenced with CO approved construction barrier fencing, plastic or portable fencing, before any construction activity. The fencing shall define the construction zone and confine activity to the minimum area required for construction. All protection measures shall be clearly stated in the construction specifications, and workers will be instructed to avoid conducting activities beyond the construction zone as defined by the construction zone fencing.

Protection of Public: Fence, barricade, or otherwise block off the immediate work area to prevent unauthorized entry. Erect and maintain fencing, barricades, lights, signals, and warning signs in accordance with MUTCD-2003.

Vines and “volunteer trees” growing on wall and roof surfaces can and should be removed to facilitate execution of the work. The DBC shall protect other tree trunks and root systems of trees adjacent to the work area.
