Unit pricing should also be considered for replacement of granular activated carbon (GAC), if GAC vapor stream treatment will be required.These par
4、agraphs should be coordinated with Sections 43 13 13.13 VAPOR PHASE ACTIVATED CARBON ADSORPTION UNITS, 01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL, and 43 11 00 FANS/BLOWERS/PUMPS; OFF-GAS.The bid sheet should include separate, optional items for tasks such as: training, pneumatic flow meter testin

Payment will be at the respective contract prices in the bidding schedule.SECTION 02 01 50 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-1.1.1 Unit
6、Pricing*NOTE: Incentives for the Contractor to complete remedial action in a timely manner should be incorporated into the pricing structure, if possible. Unit pricing alternatives for payment include: hours of operation, volume of air extracted, and mass of contaminants removed.Although pricing by
7、mass of contaminants removed creates incentive, mass of contaminants removed is more difficult to accurately measure than time or air volumes. Also there is typically a high degree of uncertainty in predicting mass removal rates, which will make it difficult for bidders to assign reasonable prices w
8、hen preparing bids.Another performance based payment option is to make periodic payments to the Contractor based on the degree of reduction in contaminant levels. For example, partial payment to the Contractor is made based on the percentage reduction in contaminant levels. However this type of paym
9、ent scheme should be used with caution, since removal rates typically decrease as contaminant levels decrease; e.g., it may take 3 times as long to go from 25 to 10 mg/kg as it takes to go from 100 to 25 mg/kg.Lump sum pricing, with performance requirements (see paragraph Operation of the SVE System
10、), is generally recommended for Operations, Maintenance and Process Monitoring. Under this pricing structure, the Contractor receives periodic payments (e.g., monthly) so long as performance requirements are being met. If performance requirements are not met, then the Contracting Officer may withhol
11、d payment until the Contractor demonstrates that performance requirements are being met.If it is expected that large volumes of condensate will be generated, and that treatment or offsite disposal will be required; then a separate paragraph should be added to cover treatment and disposal of condensa
12、te. A unit pricing structure would be appropriate to pay for treatment or offsite disposal of condensate.*Compensation shall be a lump sum price for Operation of the SVE System, Maintenance, and Process Monitoring. Costs for Contaminated Material Storage and Disposal shall also be included in this p

30、list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval.

39、ese paragraphs. The designer should also bear in mind that any SVE system operated as part of site remediation under CERCLA authority does not require federal, state or local permits. This includes all NPL and non-NPL sites being remediated under CERCLA authority such as DERP, IRP, FUDS, or BRAC pro
40、gram projects. Permits that have already been acquired should be attached to the specifications and referenced.These paragraphs should be coordinated with Sections 01 57 20.00 10 ENVIRONMENTAL PROTECTION and 43 13 13.13 VAPOR PHASE ACTIVATED CARBON ADSORPTION UNITS (if used).*Obtain required federal
41、, state, and local permits for operation of the SVE system.1.5.2 Air Emissions*NOTE: An air pathway analysis should be performed during design to determine if air monitoring will be required. Guidance on air pathway analyses is provided in EP 1110-1-21 - Air Pathway Analysis for the Design of Hazard
42、ous, Toxic, and Radioactive Waste (HTRW) Remedial Action Projects Appropriate federal, state, and local permits should be identified in this paragraph, and site specific permit requirements should also be provided. For projects where a permit is required, usually the State agency will issue an air p
43、ollution control permit (or permit equivalent) that will specify emissions control requirements. The following requirement is an example from a State air pollution control permit equivalent, “The maximum emission rate of total VOC shall not exceed 0.092 lbs/hr“.*Air emissions shall be monitored, controlled, and reported in
