B. Summary of work includes the definition found in Section 01 27 00 Definition of Contract Line

Items.

C. Generally, Work consists of the following for the Primary Treatment Facility:

1. Primary Wastewater Treatment System Rehabilitation at Cedar Grove Primary

Treatment Facility.

a. Headworks rehabilitation with the installation of a new concrete structure and overhead open cover housing waste grinding equipment, Palmer-Bowlus flume with electronic ultrasonic level sensor measuring device.

b. Septic tank cleaning, exterior surface repair, and interior of the tank reconfiguration

(baffle walls, piping, penetration coring, and patching) including additional access hatch installations for improved maintenance capability and safety railing installed around the top of the tank perimeter.

f. Install a new, larger water line connection into the pump/control building

g. Replace the main electrical disconnect at the transformer.

h. Install electrical and monitoring systems.

i. Install embed support in the septic tank cover for a portable davit crane to remove filters or pumps from the septic tank.

j. Install embed support in the headworks concrete structure for a portable davit crane to remove the effluent grinder from the headworks effluent channel for maintenance and replacement purposes.

E. For any work components wherein, the component specifications are not expressly included in these Contract Documents, the Contractor is to field verify the existing work component and then include each component as ‘like in-kind to the existing work component in the appropriate bid item in the Contract Price Schedule. The Contractor must submit a technical data sheet for the ‘like in-kind component specifications to the Contracting Officer for review and approval as part of the submittal requirements.

1.3 WORK PHASES AND SEQUENCING

A. The work shall be conducted to minimize interruptions to the Cedar Grove Wastewater

Treatment Plant (CGWWTP) processes. It is anticipated that CGWWTP will be operational during the construction period for this portion of the project. Typically, the lowest wastewater flows are observed during the months from October through April.

B. Cedar Grove WWTP: All work within the primary treatment area of the Cedar Grove Treatment must be performed following the staging plans for the site construction.

The septic tank, headworks, and pump station will be rehabilitated first during the primary treatment rehabilitation. A bypass tank and pumping configuration shall be installed near the existing headworks and be connected to the force main to completely bypass the headworks, septic tank, and pump station. Stage 1 also includes the replacement of all the electrical gear, piping, valves, generator, cabinetry, and pumps inside the control building.

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 shall be broken out separately.

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

a. United States (U.S.) Army Corps of Engineers, Ownership and Operating Expense

Schedule (use the latest edition and applicable region)

b. Construction Blue Book

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

4. Estimated equipment rates shall include operating costs of all fuel, oil, lubrication, supplies, small tools, necessary attachments, ground engaging components, tires and tracks, routine repairs, and maintenance (cost of major repair and overhaul is not allowed per Federal

Acquisition Regulation (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.

SEKI – 200843 01 26 01 - 5

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

6. Standby unit rates are used in accordance with paragraphs 1.3, D, 2, above. If the U.S.

Army Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then 1/2 of 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, an established standby rate shall apply from the first day of the delay.

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

E. Establishment and Application of Overhead and Profit Percentages:

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 31which 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………………8%

Profit………………..…8%

2. The 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 the allocation of percentages between contractors and subcontractors at any tier.

3. If Contractors form a partnership, the partnership may only receive home office overhead and profit in the same amount as an individual Contractor (refer to paragraph 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, overhead and profit mark-ups are required on 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.
