The Contractor-supplied systems will only be required to produce the human readable e-mail message with the required data items.

3.4 SENSOR SPECIFICATIONS

The Contractor shall furnish, operate and maintain all hardware and software to meet the following specifications for the Tracking, Monitoring and TDS profiles.

3.4.1 Dredge Scow Sensor Specifications

Horizontal Positioning: Horizontal dredging equipment positioning shall be provided in State Plane coordinates based on North American Datum 1983 when possible. Horizontal positioning shall be obtained using either differential Global Positioning System (DGPS) equipment operating with a minimum accuracy level of 1-3 meters horizontal Circular Error Probable (CEP) or with GPS equipment using the Wide Area Augmentation System. This accuracy level requirement is optional for the tracking profile. Differential Correction broadcasts will be furnished 24 hours/day by the Government in standard RTCM SC-104 version 2.0 output. Horizontal positioning shall be recorded to the nearest whole foot when provided in State Plane coordinates. Datum may vary according the local geodetic coordinate system in common use at a USACE District.

Date and Time: The date and time shall be reported to the nearest second in the format shown in these specifications. The time shall be referenced to Coordinated Universal Time (UTC).

Hull Status: Open/closed measurements of hopper status shall be obtained.

These data correspond to the split/not-split condition for a scow. An OPEN value refers to when the hull is split or bottom doors open. A CLOSED value refers to when the hull is not split or the bottom doors closed.

Scow Heading: Vessel headings shall be provided using industry standard equipment described in written form and approved by the Government prior to dredging. Calibration will be performed according to manufacturer's specifications prior to commencement of work and documented in the DPIP. The scow heading should be accurate to within 5 degrees and the Contractor shall report the heading to the nearest whole degree with values from 000 (true north) to 359 degrees referenced to a clockwise positive direction convention.

Scow Course: Vessel course over ground he shall be provided using industry standard equipment described in written form and approved by the Government prior to dredging. The Contractor shall provide scow course over ground (to the nearest whole degree) with values from 000 (true north) to 359 degrees referenced to a clockwise positive direction convention.

Scow Speed: Vessel speed over ground shall be provided using industry standard equipment described in written form and approved by the Government prior to dredging.

Scow Draft: Draft measurements shall be obtained to the nearest 1/10 foot from the scow's keel. Industry standard pressure sensors or an equivalent system approved by the Government or his/her representative prior to dredging may be used by the Contractor. The Contractor must provide in writing as part of the DPIP how to relate measured draft values to external draft markings on the scow. The Contractor will verify draft sensor calibration according to manufacturer's specifications prior to commencement of work and document the calibration in the DPIP. A single draft sensor may be used as part of the monitoring profile. The TDS profile will require two draft sensors one fore and one aft.

Scow Bin Level: Fore and aft bin material level measurements shall be obtained to the nearest 1/10 foot. A minimum of two sensors are required, one fore and one aft. If only two sensors are used, they should be mounted in a location as close as possible over the bin centerline. If more than one fore or one aft sensor is used, then they should be placed near the corners of the hopper and the average value of the fore sensors and the average value of the aft sensors shall be reported. A spare sensor shall be maintained for replacement during dredging. The Contractor will install and calibrate the sensors according to manufacturer's directions and guidelines.

3.5 PERFORMANCE REQUIREMENTS

3.5.1 The Contractor shall replace or repair of sensors and other necessary data acquisition equipment needed to supply the required data. Repairs shall be completed within 48 hours after a sensor failure occurs or the Contractor fails to report required data within the specified time window for scow measurements.

3.5.2 System Performance Requirement: Data return shall be greater than or equal to 95 %. Data return is defined as the total number of records sent divided by the total possible number of records if the system worked normally.

3.5.3 Data Reporting Interface: The Contractor may use any available means to transmit the data to the COE via the Internet in the required mail message format (Data Upload Reports). The data may be sent directly from the scow or from a shore based computer.

Data Measurement Interval: All profiles require a history of the time of events and report data as a series of events. Data should be measured frequently enough by the scow system to resolve the events to the accuracy specified in the following table:

Event Description Event Time Resolution Event Position Resolution

An elapsed time of 1 hour since the last event 1 minute

1 minute NA

Scow transition across a map grid cell.

1 Second 10%

An elapsed time of 1 hour since the last event 1 minute

When the scow hull is closed, each map grid cell shall have a maximum dimension of 1km square. This event can also be interpreted as when the distance from the last position equals or exceeds 1km. When the scow hull is open the grid cell dimension shall be 10m square and a sampling interval of 6 seconds is typically used. Each event report shall include the event time, position, and the hull open status. The system will have the capability of storing at least 1000 event reports.

3.5.4 Contractor Data Backup: The dredging Contractor shall maintain an archive of the data sent via SMTP for the length of the dredging project. The Contractor shall include a complete archive of project data on PC format CD-R disks with the project close out documentation.

3.6 QUALITY ASSURANCE TESTS

3.6.1 Scow QA Tests

Scow Water Test: The Contractor shall provide up to six water tests for the initial calibration associated with the TDS profile. Each water test will consist of pumping the bin out to its lowest level and then filling the bin to capacity with water. At each of the stages of the test (empty and full state), a time duration of at least two minutes will pass before going to next stage. After the first three water tests, the Government will evaluate the data for accuracy. If the data indicates an unsatisfactory calibration, a re-calibration of the sensors and review of Contractor-supplied displacement and hopper volume may be necessary before completing the final three water tests. During dredging operations, one water test per week shall be conducted.

Scow Bin Level: The Contractor shall provide a clearly readable steel weighted tape for Government use. The tape measure shall have measurements shown in foot-and-tenths and be capable of measuring the full depth in the scow bin from bin coaming. The weight for this tape will be a 6-inch diameter disk weighing between 2 and 3 pounds.

Scow Position Checks: The Government will periodically check the reported position of scows. Independent position measuring equipment will be used to verify locations. Sailing points with known locations may also be used to verify position information.

Draft measurements shall be in feet with an accuracy of 0.1 foot, and reported with a resolution to the nearest 0.01 foot relative to the fore and aft draft marks.

Each sensor shall be placed at an optimum location on the scow. Industry standard pressure sensors, or an equivalent system, may be used. Two draft sensors, one fore and one aft, will be required. At the discretion of the SI support Center, a system may use other means of measuring drafts if accuracies and resolution are maintained relative to the draft marks.

3.1.10 Scow Displacement

Scow displacement shall be reported in long tons, based on the most accurate method available for the scow. The minimum standard of accuracy for displacement is interpolation from the displacement table, based on the average fore and aft draft readings.

3.2 DATA REPORTING REQUIREMENTS

Contractor collected information shall be transmitted to the SI Database. The parameters which shall be reported to the SI Database include: trip number, date and time, hull status, scow course, scow speed, scow heading, scow draft and displacement.

3.2.1 Data Reporting Interface

The Contractor may select any commercial satellite, cellular phone, or other data communications systems available to transmit the data to the SI Database via the Internet in the required mail message format. The data transition process from the scow to the SI database must be automated. The data may be sent from the scow directly to the SI database or to a shore based computer. Data transmitted to the SI Database shall be raw data; any processing of the data conducted shore side shall be done using an automated software or programming routine. A description of this process shall be included in the DPIP.

3.2.2 Data Measurement Frequency

Data shall be logged as a series of events. Each set of measurements (e.g. time, position, etc…) will be considered an event. Data shall be measured with sufficient frequency by the scow system to resolve the events to the accuracy specified in the following table.
