1.2 WORK COVERED BY CONTRACT DOCUMENTS

A. Project Location: Boott Mill #6, 115 John Street, Lowell National Historical Park, Lowell, MA.

B. The Work consists of:

1. The work is for a cooling tower replacement on the roof of the fifth floor of the Boott

Cotton Mill #6. The project involves removing the existing rooftop cooling tower by crane

(placed at adjacent Bridge Street, requiring police detail for traffic control) and installing a new low-rise cooling tower on new vibration rails on a steel structure without disturbing the newly installed EPDM roof. Piping connections are to be made at the roof level and replace degraded connecting valves. This is one of two cooling towers for the building.

The roof does not have a parapet, so emphasis will be placed on the safety plan for the work. Work will include replacing variable frequency drives to the cooling tower system.

2. Work also includes replacing one 384 gpm 90’ head condenser pump and two 500 gpm 70’ head circulatory pumps that connect Chiller #1 (the chiller is not in this scope of work, but a separate contract will be implemented to rebuild it, and work could overlap) to the

Cooling Tower #1. Work also includes replacing degraded 6 two-way control valves, approx. 24 ball valves and flexible joints, 1 automatic control valve, 4 butterfly valves, approximately 16 lf of pipe and connections necessary to complete the connections, 3 sets of vibration springs and mounting to existing concrete pads. Electrical work shall include new conduit and wiring as necessary to tie in the new motors.

3. Option #1 is to replace one circulatory pump in the adjacent building basement mechanical room. Work will include adding variable frequency drive to the pump. Work includes replacing degraded 2 two-way control valves, 8 ball valves, 1 automatic control valve, 2

LOWE - 337427 01 11 00 - 2

butterfly valves, approximately 8 lf of pipe and connections necessary to complete the system, 1 set of vibration springs and mounting to existing concrete pad; and program the cooling tower and the pump to the Trane Building Management System. Electrical work shall include any new conduit and wiring.

MODIFICATION PROPOSAL PRICING REQUIREMENTS

A. 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.

LOWE - 337427 10 26 01 - 6

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:

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.

Overhead…………10%

Profit………………8%

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.

1.5 ALLOWANCES

A. Allowance Adjustment: To adjust allowance amounts, base each Change Order proposal on the difference between purchase amount and the allowance, multiplied by final measurement of work-in-place. If applicable, include reasonable allowances for cutting losses, tolerances, mixing wastes, normal product imperfections, and similar margins.

1. Include installation costs in purchase amount only where indicated as part of the allowance.

2. If requested, prepare explanation and documentation to substantiate distribution of overhead costs and other margins claimed.
