c. Debris Delays: Anticipate delays that may occur for removal and disposal of debris. The time to remove debris will not be the basis for a Contract time extension.

3.1.3 Layout of Work

The Contractor will be provided layout charts for all dredging areas based on the schedule of work, the Contractor's hydrosurvey requests, and/or the results of Government hydrographic survey monitoring. The most current Government hydrosurvey information will be displayed on the dredging layout charts and provided to the Contractor. All depths are measured from mean lower low water (MLLW) with the exception of reaches in CLW above RM 20 which is measured in Columbia River Datum (CRD) as shown. Other pertinent information to be included with each layout package will be: payment method, required and maximum dredging depths, coordinates for the material placement site, distance one-way from dredging location to placement site (CLW), specific placement site instructions, supplemental tide gauge information, horizontal control locations, and computed hydrosurvey quantities.

3.1.4 Dredging Requirements

a. Dredging Locations:

(1) HUM

(a) As determined by the results of a hydrographic survey monitoring, the Government will direct the Contractor to dredging areas within Humboldt Bay Entrance. The Government will provide a required dredging depth between -42 to -50 feet MLLW with a maximum pay depth 1- to 2-feet below that. Payment will be made by bin measure to required depth from mechanical ullage sensors. See 01 22 00.00 82, MEASUREMENT AND PAYMENT for additional information.

(b) Material placement will be HOODS site. See Section 01 22 00.00 82, MEASUREMENT AND PAYMENT for more details.

(c) It is possible that a Government dredge will conduct dredging operations at HUM prior to the arrival of the Contractor. Careful consideration of the timing of pre dredge surveys should be given.

(2) CLW (RM 3+00+00 to RM 105+00+00)

(a) As determined by the results of hydrographic survey monitoring, the Government will direct the Contractor to dredging areas within CLW between RM 3+00+00 to RM 105+00+00.

This direction will be provided in the form of a written direction to commence work and attached layout package as referenced in subitem (b). In chronic shoaling areas, the Contractor may be directed to dredge up to 100 feet outside of the navigation channel in the "advanced maintenance width" area.

(b) Anticipate the necessity to perform work at many CLW dredging areas during the performance period. The Contractor may be directed to multiple work areas in succession or may be directed to return to other projects after completing just one.

SECTION 35 20 23.00 82 Page 4

Dredging must commence at the first dredging area within 48 hours of receiving written direction and the applicable dredging area layout chart (if the dredge is transiting from MCR). In successive dredge areas, the layout chart will be provided within 24 hours prior to the start of dredging at a new area. The Contractor must provide notice 72 hours in advance of the anticipated completion of a work area, or immediately upon receiving the layout drawing if completion is anticipated in less than 72 hours.

(c) In Bin Measure work areas, the Government will provide a dredging pay depth between -40 to -48 feet. The required quantity will be a minimum of 50,000 CY, unless mutually agreed upon between the Government and the Contractor.

(d) In Pre/Post Dredge Survey work areas, the Government will provide a required dredging depth between -40 to -47 feet with a maximum pay depth one foot below the required depth. There will be greater than 75,000 CY available in the dredging pay prism, unless mutually agreed upon between the Government and the Contractor.

(e) In Bin Measure to Required Depth work areas, the Government will provide a required channel depth between -40 to -47 feet with a maximum pay depth one foot below the required depth.

Based on the CLIN from which payment will be made off of, namely CLINs 0013 and 0014, there will be either between 30,000 and 75,000 CY, or greater than 75,000 CY available in the dredging pay prism, unless mutually agreed upon between the Government and the Contractor. For information on specific CLIN structure, reference Sections 00010 and 01 22 00.00 82.

(f) Material placement areas will be within five Columbia River miles (one way) from the centroid of the dredging area to the centroid of the placement area. In the event that the material placement location is greater than five Columbia River miles (one way), an incremental cost will be applied as detailed in Section 01 22 00.00 82, MEASUREMENT AND PAYMENT.

(3) COO

(a) As determined by the results of a hydrographic survey monitoring, the Government will direct the Contractor to dredging areas within Coos Bay Entrance. The Government will provide a required dredging depth between -37 to -51 feet MLLW with a maximum pay depth 1 foot below that. The Contractor should take note of the transition zone between RM 0+20 and RM 0+40 where channel depths transition from -47 feet MLLW to -37 feet MLLW plus 5 advanced maintenance (see Plan Drawing WCH-COO-000 for details). Payment will be made by bin measure to required depth from mechanical ullage sensors. See 01 22 00.00 82, MEASUREMENT AND PAYMENT for additional information.

(b) Material placement will be Site F placement site. See Section 01 22 00.00 82, MEASUREMENT AND PAYMENT for more details.

(4) MCR
