If there is a separate Measurement and Payment Section, edited versions of these paragraphs should be inserted in that section.If the quantitie
20、s of contaminated soils are well defined, payment may be based upon a lump sum structure. However, it is usually more cost-effective to use a unit price structure when there is a significant degree of uncertainty in the amount of contaminated material. When specifying a unit price structure for trea
21、tment, separate items should be provided in the Contract Price Schedule to cover any other work required. Other work items include, but are not limited to: preparation of submittals, mobilization and demobilization, site preparation, construction of the treatment cell and run on/runoff controls, wat
22、er storage facilities, contact water treatment and disposal, sampling and testing, implementing health and safety requirements, and utilities. Inclusion of separate items in the Contract Price Schedule for the above work tasks should result in a lower unit price for treatment.*1.1.1 Bench-Scale Test
23、ing*NOTE: Lump sum pricing is recommended for this item. The lump sum should include the cost for testing for chemical data. However, bidders should also be required to provide a unit cost amount for testing for chemical data. This will provide a basis for payment for additional analytical costs, if
24、 it is determined that more testing will be SECTION 02 54 20 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-required.*Payment for bench-scale testing will be a lump sum price for completion of specified tests. The price shall include the cost
25、of labor, materials, equipment usage, utilities, and fuel for: preparation of the Bench-Scale Test Plan collecting samples, sample shipment, pre-processing, process monitoring (including testing for chemical data), disposal of treated material, ancillary waste treatment and disposal, preparation of
26、the Bench-Scale Test Report, and _. Costs for procurement and handling of amendments shall be included in the unit price for treatment.1.1.2 Field Demonstration*NOTE: Prior to planning the field demonstration, bench-scale testing should be performed to determine if the contaminants of concern are am
27、enable to landfarming in the site-specific soil matrix. The field demonstration may either be conducted prior to the construction of the full-scale facilities, or conducted using the full-scale facilities and equipment. Payment for the field demonstration should be covered by a separate lump sum ite
28、m, or by a unit price that is separate from the unit price for full-scale treatment. Because more intensive monitoring is usually required during the field demonstration, the unit price for the field demonstration will usually be higher than the unit price for full-scale treatment. Testing for chemi
29、cal data is not included as a component of the price in this paragraph. The contract price schedule should include separate, unit price items for testing for chemical data.If the results of the field demonstration indicate that an extended treatment period (or other special measures) will be require
30、d to meet cleanup goals, it may become necessary to modify the bid item that covers treatment pricing for full-scale operations.*Payment for the field demonstration will be by the contract unit price schedule for each cubic meter yard _ treated during the field demonstration a lump sum price for com
31、pletion of approved tests. The price shall include the cost of labor, materials, equipment usage, utilities, and fuel for: excavation, hauling, stockpiling, pre-processing, operation, maintenance and process monitoring (not including testing for chemical data), disposal of treated material, ancillar
32、y waste treatment and disposal, preparation of Field Demonstration Report, and _. Costs for procurement and handling of amendments shall be included in the unit price for treatment.1.1.3 Contaminated Soils Treatment Unit Price*NOTE: Testing for chemical data is not included in the unit price. The co
33、ntract price schedule should include separate, unit price items for testing for SECTION 02 54 20 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-chemical data.Unit price payment may either be based on weight or volume (in-place or ex-situ). Thi
34、s paragraph uses ex-situ volume as the default unit.If unit price payment will be based on weight, dry weight should be specified and requirements should be included for moisture content testing so that dry weight can be determined. However, surveys are usually required before and after excavation o
35、f contaminated material, so that excavation and backfilling can be paid for on the basis of in-place volume. Thus, in some cases, it may be advantageous to pay for processing and treatment of soils using in-place volume as the pricing unit. Payment may also be based on ex-situ volume, after the over
36、size materials have been separated from the soil. Because of the bulking which usually occurs during excavation of soil, ex-situ volume will usually be about 30 percent greater than the in-situ volume. If there is a substantial volume of oversize material, or if a substantial volume of excavated mat
37、erial will not require treatment, it may be advantageous to use ex-situ volume as the basis for payment.This paragraph should be coordinated with the treatment criteria and sampling requirements paragraphs so that it will be possible to distinguish between soil that passes, and does not pass, treatm
38、ent criteria.*Payment for treatment of contaminated soil shall be by the contract unit price schedule for each cubic meter yard _ based on ex-situ volume, after separation of oversize material _. This unit price shall include the cost of labor, materials, equipment usage, utilities, and fuel for: ex
39、cavation, hauling, stockpiling, pre-processing, operation, maintenance and process monitoring (not including testing for chemical data), disposal of treated material, ancillary waste treatment and disposal, preparation of operations reports, and _. Costs for procurement and handling of amendments sh
40、all be included in the unit price for treatment. After each lift of soil has been treated, the quantity of soil that does not meet treatment criteria shall be reported and subtracted from the quantity of soil comprising the lift, when determining payment for treatment. See paragraph Treatment Cell S
41、izing below, for a definition of “lift of soil“. Payment will not be made for soil that does not meet treatment criteria. If additional tests, or additional processing and testing, are necessary to show that material meets treatment criteria, the additional costs shall be borne by the Contractor.1.1
42、.4 Oversize Materials from Contaminated Areas*NOTE: This paragraph should be deleted if payment for treatment and disposal of oversize materials will be included as part of the unit price item for SECTION 02 54 20 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without lic

Oversize materials may include brush, trees, roots, rocks, rubble, and construction debris.*Payment for and disposal treatment of oversize material separated from contaminated soil will be by the contract unit price schedule for each kilogram pound _. Soil, free water and other extraneous materials shall be separated from oversize materials prior to measuring quantities.1.2 REFERENCES*
