3.3.2 Quantity Surveys

a. Wahkiakum Ferry Crossing: The Government will determine cubic yard quantities for payment and acceptance by utilizing electronic depth sounding and horizontal positioning equipment. Sounding depths used for determination of pay quantity volumes will generally be derived from surveys utilizing 208 kHz single-beam acoustic methods. For computations of pay volumes, survey lines will be run cross channel every thirty feet. Volumes will be calculated using the all file.

b. Longview Turning Basin: The Government will determine cubic yard quantities for payment and acceptance by utilizing electronic depth sounding and horizontal positioning equipment. Sounding depths used for determination of pay quantity volumes will be derived from surveys utilizing multi-beam methods with HYPACK's Advanced Channel Design for volume calculations. For computations of pay volumes, multi-beam survey data will be processed using a median depth sort with a 5 by 5 foot Matrix.

NOTE: Due to unexpected ship traffic at the dock in the Longview Turning Basin work area the Government may be required to run multiple surveys in order to gather all needed data for pre-dredge and post-dredge surveys of the area. Once all data has been collected the survey data will be compiled into one data set. The data sets will be compared before compiling and overlapping validated data would be edited to bias towards the sounding that would result in the calculated volume computations to be the greatest possible value (Ex: default to a shallower sounding on the compiled pre-dredge survey and default to a deeper sounding on the post-dredge survey.)

c. As required, data from land surveys will be obtained and incorporated into the volume computation.

d. The dredging pay area is defined by intersection of the maximum dredging pay depth and the dredging pay slope. The number of cubic yards calculated as being payable will be the difference between the most recent pre-dredge and post-dredge surveys of the dredging pay area or applicable acceptance area. Any material removed from outside the maximum dredging prism will not be considered for payment.

e. Accuracy(ies) will be in accordance with stated quality control values in EM-1110-2-1003. Upon request, the Government will provide the survey line files by which surveys are run.

f. Government Equipment: The following survey equipment will be used by the Government Survey Crew during the collection of sounding data and will be considered the standard for which data is obtained:

Positioning: Applanix Wavemaster or Applanix POS MV 4 Multibeam: RESON T-50 MB Singlebeam: ODOM CV100 ECHOSOUNDER with an 3 degree 200khz transducer AML Velocity Probe AML Sound Velocity Profiler

Note: The Government will be available by request to run check
