CONTRACTOR will transport and dispose of contaminated material at an approved disposal/treatment facility.

CONTRACTOR shall provide the ENGINEER with a copy of the contaminated soil disposal receipt.

3. Handling of Contaminated Soil

After approval from the ENGINEER, excavate the soil in a manner that prevents commingling of contaminated and non-contaminated soil. ENGINEER will make determination (based on soil saturation) if contaminated soil can be directly transported to a treatment or disposal facility, or if soil needs to be stockpiled to reduce water content. ENGINEER will determine when stockpiled soil can be transported off-site.

CONTRACTOR will be responsible for stockpiling contaminated soil in containers or on impervious surface to prevent the spread of contamination. Any water runoff from the contaminated soil stockpile area(s) must be contained by CONTRACTOR and handled as contaminated water.

Minimize movement of excavation equipment over or through contaminated soil to prevent movement of contaminated soil into areas where no contaminated soil exists.

Stockpiles will be created on an approved site and shall be surrounded by a fence to limit access. The stockpiles must be covered and bermed during periods of rainfall to prevent run-on and run-off. The stockpiles shall be covered with a minimum 10-mil high density polyethylene (HDPE) plastic during periods of strong winds, nightfall, over the weekends, or during extended work stoppages. If dust is

20-2888 01 10 00 - 15 observed coming from the stockpiles, the stockpiles shall be either covered or the dust controlled with water.

Maintain excavation equipment in good working order. Prevent spillage of oil, fuel, or hazardous substances from equipment. In particular, promptly repair oil leaks from equipment and clean up any contaminated soil.

4. Transport of Contaminated Materials

CONTRACTOR shall comply with all applicable Federal, State, or local laws, codes, and ordinances that govern or regulate contaminated substance transportation.

Contaminated soils placed in stockpiles shall be loaded into trucks in a manner that prevents the spilling or tracking of contaminated soil into areas of the site with uncontaminated soil. Loose material falling onto the exterior of the truck during loading shall be removed before the truck leaves the loading area. Any material collected in the loading area shall either be placed back into the truck or back into the stockpile. If loading areas are unpaved, the surface soil shall be sampled at the conclusion of the loading activities to confirm that contaminated soil is not present.

If loading areas are paved, any loose soil shall be cleaned from the pavement at the conclusion of the loading activities.

SECTION 01 22 20

UNIT PRICE MEASUREMENT AND PAYMENT

PART 1 GENERAL

Measurement and payment will be on a unit price basis in accordance with the prices set forth in the proposal for individual work items. Where work is required but does not appear as a separate item in the proposal, the cost for that work shall be included and absorbed in the unit prices named in the proposal. CONTRACTOR shall make a careful assessment when preparing the bid.

1. Mobilization, bonds, insurance and demobilization: Payment for mobilization, bonds, insurance and demobilization will be on a lump sum basis. The amounts paid for mobilization in the contract progress payment will be based on the percent of the original contract amount that is earned from other contract items, as follows:

A. When 5% is earned, either 100% of the amount for mobilization or 5% of the original contract amount, whichever is the least;

B. When all work is completed, amount of mobilization exceeding 5% of the original contract amount

This schedule of mobilization progress payments will not limit or preclude progress payments otherwise provided by the contract.

2. All work required to construct two 7.5 MG prestressed concrete tanks: Measurement and payment for all project work required to construct two 7.5 million gallon (MG) prestressed concrete tanks, complete, other than as provided for under separate unit prices, will be made on a single lump sum basis. For purposes of evaluating monthly partial payments, this lump sum is broken down as follows:

d. Site preparation including minor preliminary site grading, backfill and finish grading

e. Tank construction (2 EA 7.5 MG) including foundation, structure, interior piping, mixing system, interior stairs, hatches and appurtenances.

f. Tank testing, disinfection and start-up

20-2888 01 22 20 - 2

g. Valve vault

h. Water piping including pipe, valves, fittings, restraints and flexible expansion joints.

i. Testing, flushing and disinfection of water mains

j. Site stormwater facilities, complete

k. Tank overflow & drain facilities start-up and testing

l. Tank monitoring manhole

m. Water quality monitoring facilities including enclosures, piping and valves

n. Site access road, parking area and tank access roads with surfacing, drainage ditches and features noted and as shown in the Drawings

o. Electrical, instrumentation & control, and telemetry improvements

p. Maintain owner-provided temporary site fencing

q. Final site grading, surface restoration and site clean-up

r. Site access gate and bollards

s. Traffic control

t. As-built drawing preparation and post-construction survey

Lump sum payment under this item shall cover all particular elements of the project as above generally outlined, whether or not specifically identified, as specified herein and as shown on the Drawings, except for work included separately under other unit price bid items.

3. Tank leak detection system (30-mil PVC liner): Payment for installation of the PVC liners, associated geotextiles, enclosed drain rock and HDPE piping will be made on a lump sum basis.

4. Rock excavation: Payment for rock excavation will be made at the unit price per cubic yard of rock excavated and rock excavation will be paid for in addition to the lineal foot price for pipe, trench excavation and backfill and site excavation for structures. The pay limits for pipe trench shall be 12 inches below the pipe invert and the width shall be the nominal pipe diameter plus 1 foot on each side of the pipe. Pay limits for vaults and other structures shall be to the depth necessary to install the structure and to a maximum of 18 inches beyond the outside walls of the vault or structure. No payment will be made for rock excavation beyond these limits.

20-2888 01 22 20 - 3

Rock excavation is defined in Section 31 23 18, Rock Removal and as determined by the Engineer. Rock excavation will be measured by surveying coordinates and elevations of the solid rock surface prior to and following excavation of the rock; the total quantity of rock excavated will be calculated from these measurements. Rock measurement will be subject to approval by the Engineer. Cost of surveying rock measurement shall be the responsibility of the Contractor. No additional payment will be made for common excavation beyond these limits to remove solid rock and/or boulders nor will payment be made for select backfill beyond these limits placed to fill voids left by removing solid rock and/or boulders.

Contractor’s attention is directed to Section 01 10 00, Summary of Work, which disallows Contractor’s use of explosives in the excavation and removal of rock.

5. Additional cost for overexcavation and select backfill material for unsuitable conditions:

Payment for overexcavation and select structural backfill material for unsuitable tanks structure foundation conditions, unsuitable site stormwater detention facility and unsuitable site piping soil conditions will only be considered as approved by the Engineer in writing.

When such pre-approval is obtained, payment will be made on a per cubic yard basis for the backfill material. Unsuitable material is assumed to be common excavation. Measurement will be agreed upon by CONTRACTOR and ENGINEER prior to overexcavation.

6. Construction Water and Sediment Management Plan. Payment for the construction water and sediment control plan meeting the City of Eugene 1200-CN permit conditions will be made on a lump sump basis. Work includes preparation of a management plan by a licensed engineer, submission of the plan to City of Eugene for review, and installation and operation of temporary measures as needed to meet the permit conditions until permanent site stormwater runoff is accepted. Work includes installation and maintenance of all erosion control measures such as silt fencing, inlet protection and sheeting of exposed cut slopes.
