SUMMARY OF CHANGES
SECTION 00100 - BIDDING SCHEDULE/INSTRUCTIONS TO BIDDERS
The following have been added by full text:
AMENDMENT 0001
Question #1:
We are in receipt of the plans for Wood Island Harbor, Biddeford, Maine Project. Our experience from the 1992 USACE Project at this site tells us that the channel should be engaged by way of a barge mounted hydraulic excavator, unlike in 1992 when it was engaged with a hydraulic cutterhead dredge. The channel sand is extremely hard and not engageable as a practical matter. The specifications call for a mechanical bucket for material removal by open and closed style bucket. The channel work demands a hydraulic extractor with open-toothed bucket to suitable engage the material. Your South Pool anchorage area as shown on contract drawing sheet C-102, is requesting the use of a “closed bucket”, this makes it difficult as we would likely have to swap an excavator for a crane on the same dredge platform. We request the use of a ditching style non-tooth bucket be allowed for use with a hydraulic excavator to engage this silty anchorage area as shown on contract sheet C- 102.
Government Response: Per Specifications Section 35 20 23 Subpart 3.1.1b, the "closed bucket" requirement only applies to the silt material area of the anchorage indicated on the contract drawings (Sheet C-102). For all of the 10-foot channel work and the majority of the anchorage, the open bucket (Open toothed, non- toothed, etc.) is allowed for engaging the hard packed sand material. During construction, if the contractor encounters hard sand refusal using the closed bucket within the silt zone shown, the Contracting Officer's Representative (COR) will make a field determination on whether the open bucket may be used for that specific location. The closed bucket requirement is based on environmental impact and turbidity control considerations. It cannot be replaced by an open bucket for the entirety of the silt area, only in such instances as described above.
Closed bucket equipment is commercially available for hydraulic excavators.

NATIONAL DREDGING QUALITY MANAGEMENT PROGRAM
SCOW - MONITORING PROFILE
30 August 2019
PART 1 GENERAL
1.1 DESCRIPTION
The work under this contract requires use of the National Dredging Quality Management Program (DQM) to monitor the scow's status at all times during the contract and to manage data history. For the purpose of these specifications, a scow is defined as any non-self-propelled vessel used to transport dredged material. This includes, but is not limited to, split-hull scows, pocket scows, hopper barges, and deck barges.
This performance-based specification section identifies the minimum required output and the precision and instrumentation requirements. The requirements may be satisfied using equipment and technical procedures selected by the Contractor.
1.2 SUBMITTALS
Government approval is required for submittals with a "G" designation;
submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office responsible for review of the submittal for the Government. The following shall be submitted in accordance with Section 01 33 00, "SUBMITTAL
PROCEDURES":
SD-01 Preconstruction Submittals
Dredge Plant Instrumentation Plan Revisions or Addendum;
G, SJ
SD-07 Certificates
Letter of National Dredging Quality Management Program Certification; G, RO
1.3 PAYMENT
No separate payment shall be made for installation, operation, and maintenance of the DQM-certified system as specified herein for the duration of the dredging operations; all costs in connection therewith will be considered a subsidiary obligation of the Contractor and covered under the contract unit price for dredging in the bidding schedule.
1.4 NATIONAL DREDGING QUALITY MANAGEMENT PROGRAM CERTIFICATION
The Contractor is required to have a current certification from DQM for the scow instrumentation system to be used under this contract. Criteria for certification shall be based on the most recent specification posted on the DQM website (http://dqm.usace.army.mil/Specifications/Index.aspx).
Compliance with these criteria shall be verified by onsite quality
SECTION 35 20 24 Page 3 assurance (QA) checks conducted by the DQM Support Center Data Acquisition and Analysis Team and by periodic review of the transmitted data. If a system is installed specifically for this contract, in order to ensure that it is capable of transmitting quality data to the DQM database, the QA checks should take place either prior to the start of the contract or, with prior approval of the local USACE District, as soon as practical after dredging commences. DQM certification is valid for one year from the date of certification and is contingent upon the system's ability to meet the performance requirements as outlined in Paragraph 3.3, "Performance Requirements." If issues with data quality are not corrected within 48 hours, the system certification shall be revoked and additional QA checks by the Data Acquisition and Analysis Team may be necessary.
Annual DQM certification shall be based on the following:
A series of QA checks as outlined on the DQM website (https://dqm.usace.army.mil/Certifications/Index.aspx
Verification of data acquisition and transfer as described in Paragraph3.3, "Performance Requirements")
Review of the Dredge Plant Instrumentation Plan (DPIP) as described in Paragraph 1.5, "Dredge Plant Instrumentation Plan (DPIP)"
The Dredging Contractor shall have personnel who are familiar with the system instrumentation and who have the ability to recalibrate the sensors on site during the QA process. The Dredging Contractor shall coordinate pickup times and locations and provide transportation to and from any platform with a DQM system to team personnel in a timely manner. The Dredging Contractor shall also have on site for the QA checks a tug capable of towing the scow. As a general rule, DQM Data Acquisition and Analysis Team personnel will come with personal protective equipment (PPE) consisting of hardhats, steel toe boots, and life jackets. If additional safety equipment is needed - such as eye protection, safety harnesses, work gloves or personal location beacons - these items shall be provided to the team while on site. The Contractor shall submit a test data package to the DQM database from the system on each scow and have it accepted by the DQM Support Center prior to scow compliance checks. The Contractor shall also submit data collected during the QA checks from the scow monitoring system to the DQM database and the Data Acquisition and Analysis Team personnel while on site. It is the Dredging Contractor's obligation to inform the QA team if the location designated for the QA checks has any site-specific safety concerns prior to their arrival on site.
The owner or operator of the scow shall contact DQM at DQM-AnnualQA@rpsgroup.com on an annual basis, or at least three weeks prior to the proposed beginning of dredging, to schedule QA checks. This notification is meant to make the Data Acquisition and Analysis Team aware of a target date and the contract on which the plant will be used. At least one week prior to the target date, the Dredging Contractor shall contact the Data Acquisition and Analysis Team and verbally coordinate a specific date and location. The Contractor shall then follow up this conversation with a written email confirmation. The owner/operator shall coordinate the QA checks with all local authorities including, but not limited to, the local USACE Contracting Officer's Representative (COR).
Recertification is required for any yard work which produces modification to displacement (for example, a change in scow lines, or repositioning or
SECTION 35 20 24 Page 4 repainting hull marks), modification to bin volume (change in bin dimensions or addition or subtraction of structure), or changes in sensor type or location; these changes shall be reported in the sensor log section of the DPIP A system does not have to be transmitting data between jobs; however, in order to retain certification during this period, the system sensors or hardware should not be disconnected or removed from the scow. If the system is powered down, calibration coefficients shall be retained.
1.5 DREDGE PLANT INSTRUMENTATION PLAN (DPIP)
The Contractor shall have a digital copy of the DPIP on file with the DQM Support Center. While working on site, the Contractor shall also maintain on the dredge a copy of the DPIP which is easily accessible to Government personnel at all times. This document shall describe the sensors used, configuration of the system, how sensor data will be collected, how quality control on the data will be performed, and how sensors/data reporting equipment will be calibrated and repaired if they fail. A description of computed scow-specific data and how the sensor data will be transmitted to the DQM database shall also be included. The Contractor shall submit to the DQM Support Center any addendum or modifications made to the plan, subsequent to its original submission, prior to the start of work.
A complete list of the required DPIP contents is provided on the DQM website (https://dqm.usace.army.mil/Certifications/Index.aspx).
The Contractor shall submit to the DQM Support Center any addendum or modifications made to the plan, subsequent to its original submission, prior to the start of work. Any changes to the computation methods shall be approved by the DQM Support Center prior to their implementation.
PART 2 PRODUCTS (Not Applicable)
PART 3 EXECUTION
3.1 REQUIREMENTS FOR REPORTED DATA
The Contractor shall provide, operate, and maintain all hardware and software to meet these specifications. The Contractor shall be responsible for the replacement, repair, and calibration of sensors and other necessary data acquisition equipment needed to supply the required data.
Repairs shall be completed within 48 hours of any sensor failure. Upon completion of a repair, replacement, installation, modification or calibration the Contractor shall notify the Contracting Officer's Representative (COR). The COR may request recalibration of sensors or other hardware components at any time during the contract as deemed necessary.
The Contractor shall keep a log of sensor repair, replacement, installation, modification and calibration in the onsite copy of the DPIP.
The log shall contain a three-year history of sensor maintenance including the time of sensor failures (and subsequent repairs), the time and results of sensor calibrations, the time of sensor replacements, and the time that backup sensor systems were initiated to provide the required data. It shall also contain the name of the person responsible for the sensor work.
Sensors installed shall be capable of collecting parameters within
SECTION 35 20 24 Page 5 specified accuracies and resolutions indicated in the following subparagraphs.
With the exception of position and any value calculated, reported sensor values should represent a weighted average with the highest and lowest values not included in the calculated average for the given interval. The averaging routine used should be consistent across all event triggers.
This information should be documented in the DPIP sections that say "Calculations done external to the instrumentation."
These data-reporting requirements cover the collection of electronic data on a scow through the entire dredging cycle. Disposal events can consist of both open-water disposal and offloading. Open water-disposal is the placement of material via bottom doors or split hull. Offloading is the placement of material via either hydraulic or mechanical means.
3.1.1 Scow Name
Each scow shall be assigned a unique name that will remain constant from one dredging operation to the next.
3.1.2 Contract Number
The USACE-assigned contract number for the project will be reported.
3.1.3 Load Number
A DQM load number shall document the end of a disposal event for a given scow.
3.1.4 Horizontal Positioning
Horizontal positioning shall be recorded as the geographic coordinates of the vessel as indicated by the location of the Global Positioning System (GPS) antenna. All locations shall be obtained using a positioning system operating with a minimum accuracy level of 1 to 3 meters horizontal Circular Error Probable (CEP). Positions shall be reported as Latitude/Longitude WGS 84 in decimal degrees. West Longitude and South Latitude values are reported as negative.
3.1.5 Date and Time
The date and time shall be reported to the nearest second and referenced to Universal Time Coordinated (UTC) based on a 24-hour format; yyyy-mm-dd hh:mm:ss.
3.1.6 Hull Status
Hull status is meant to reflect a condition when material could be removed or released from the scow.
For this contract, hull status shall register closed prior to leaving the disposal area.
3.1.6.1 Open-Water Disposal
An open split hull or open bottom door of a scow shall be indicated by reporting an "OPEN" value. A closed split hull or closed bottom door of a scow shall be indicated by reporting a "CLOSED" value. An open status
SECTION 35 20 24 Page 6 shall be indicated as the bin starts to open, and a closed status shall be indicated only once the bin is fully closed. For pocket scows, the open/closed status shall correspond to the compartment which is first to open and last to close.
3.1.6.2 Offloading
For non-dumping scows, an "OPEN" value shall indicate that the bin is in the process of being unloaded, either by pumping or mechanical means.
3.1.7 Course
Scow course-over-ground (COG) shall be provided using industry-standard equipment. 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.
3.1.8 Speed
Scow speed-over-ground shall be provided in knots using industry-standard equipment with a minimum accuracy of 1.0 knot and resolution to the nearest 0.1 knot.
3.1.9 Heading
Scow heading shall be provided using industry standard equipment. The scow heading shall be accurate to within 5 degrees and reported to the nearest whole degree, with values from 000 (true north) to 359 degrees referenced to a clockwise positive direction convention.
3.1.10 Draft
All reported draft measurements shall be in feet, tenths. and hundredths with an accuracy of +/- 0.1 foot relative to observed physical draft readings. The measurements shall be reported at a resolution of two decimal places (hundredths of a foot). The reported forward draft value shall be equal to the sum of the visual forward port and starboard draft mark readings divided by two. The reported aft draft value shall be equal to the sum of the visual aft port and starboard draft mark readings divided by two. Forward draft, aft draft, and average draft will be reported. Sensors shall be placed at an optimum location on the scow to be reflective of observed physical draft mark readings at any trim or list.
Minimum accuracies are conditional to relatively calm water. The sensor value reported shall be an average of at least ten samples per event, with at least one maximum value and one minimum value removed, and the minimum eight remaining values averaged. When the average draft is calculated for the purpose of determining displacement, significant digits for average draft shall be maintained such that if forward draft were 0.15 and aft draft were 0.1, then the average draft would be 0.125.
3.1.11 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 draft. For this contract the density of water used to calculate displacement shall be 1027-1030 kg/m3 (1.027-1.03g/cm3) and shall be used for an additional interpolation between the fresh and salt water tables.
SECTION 35 20 24 Page 7
3.2 NATIONAL DREDGING QUALITY MANAGEMENT PROGRAM SYSTEM REQUIREMENTS
The Contractor's DQM system shall be capable of collecting, displaying, and transmitting information to the DQM database. The parameters which shall be reported to the DQM database include trip number, date and time, hull status, scow course, scow speed, scow heading, draft, and displacement. An easily accessible, permanent visual display on the scow shall show in real time the parameters collected by the system in the same units as are used for data submitted to the DQM database. In the event a reported parameter is calculated based on multiple sensors, the sensor values as used in the equation shall be able to be viewed in addition to the required parameter. If a hardware problem occurs, or if a part of the system is physically damaged, then the Contractor shall be responsible for repairing it within 48 hours of determination of the condition.
3.2.1 Telemetry
The Contractor may select any commercial satellite, cellular phone, or other data communications systems available as long as it is capable of transmitting real-time data as well as enough additional bandwidth to clear historically queued data when a connection is reobtained. If connectivity is lost, unsent data shall be queued and transmitted upon restoration of connectivity. Delays in pushing real-time data to the DQM database should not exceed four hours. Exceptions to these requirements may be granted by the DQM Center on a case-by-case basis with consideration for contract-specific requirements, site-specific conditions, and extreme weather events.
The data transition process from the scow to the DQM database must be automated. The data may be sent from the scow directly to the DQM database or to a shore-based system. Data transmitted to the DQM database should be raw data; any processing of the data conducted shoreside shall be done using repeatable automated software or programming routine. A description of this process shall be included in the DPIP.
3.2.2 Data Reporting Frequency
Disposal activities shall be logged with high temporal and spatial resolution. Data shall be logged as a series of events. Each set of measurements (time, position, etc.) will be considered an event. Any required information in Paragraph 3.1, "Requirements for Reported Data," that is not an averaged variable (that is, draft and ullage) shall be collected within 1 second of the reported time. Data shall be measured with sufficient frequency by the scow system to resolve the events to the accuracy specified in the following table. Any averaged variable must be collected and computed within this sampling interval. Event types "Sailing," "Loading/Stationary," "Offloading," and "Open Water Disposal" are triggered by a time criterion; the criterion should be consistent across the "Sailing" and "Open Water Disposal" event types and should not change for the data collected on a given scow. This criterion should be documented by the Contractor in the DPIP.
Event Event Event Time Position Type Event Trigger Descriptions Resolution Resolution Loading/ No change in position with hull status closed 1 minute N/A Stationary An elapsed time of 1 hour since the last event.
SECTION 35 20 24 Page 8
No change in position with hull status open
-------------NONCLOSURE-------
In the event a scow has completed an open water disposal and transited back to a holding station without closing the hull, the sampling shall be changed to once per hour.
Sailing Change in position with hull status closed 1 second +/-10 ft
Time from the last sample equals 1 minute.
Open Hull status open 1 second +/-10 ft Water A position must be recorded within 1 second of
Disposal the hull status going from closed to open and again within 1 second of the hull status going from open to closed. The position shall be reported at any equal interval from 6 to 12 seconds. This interval shall always remain consistent for the dredge plant.
Offloading Offloading material, hull status reported as 1 second +/-10 ft open A position must be recorded within 1 minute arrival at the offload location and within one second of the material starting to be removed from scow. The time from the last sample equals 1 minute.
--------STANDBY OFFLOADING-----
In the event a scow is not being actively 1 minute offloaded at the offload location for a time equal to one hour, the sampling interval shall be equal to once an hour.
Example: The scow is stationary for 1 hour and 15 minutes, and then it sails to the disposal area. You should have a "Loading/Stationary" event at time 0 time 1 hour, and time 1 hour and 15 minutes. Then, for "Sailing," within 1 second of an elapsed time of 1 minute from the 1 hour and 15 minutes event, another event occurs.
3.2.3 Data Transmission to the Web Service
A Simple Object Access Protocol (SOAP) web service shall be used to report sensor data to the DQM database. Data shall be transmitted as it is collected in real time and pushed to the DQM web service. If the web service is not available or returns an error message, the data shall be stored in a queue and transmitted upon re-establishment of the connection, starting with the oldest data in the queue and continuing until real-time transmission is restored. Delays in pushing real-time data to the DQM database should not exceed four hours. Exceptions to these requirements may be granted by the DQM Support Center on a case-by-case basis with consideration for contract-specific requirements, site-specific conditions, and extreme weather events.
Contact dqm-support@usace.army.mil to obtain the web service URL and the appropriate key credentials and communication protocol.
The data transmission method call takes two arguments: a string containing the plant identifier assigned by the DQM Support Center and a second string containing the JSON-formatted sensor data. The method returns the
SECTION 35 20 24 Page 9 string "OK" if the data is received. If the data is not received, either the web service or the client application throws an error.
3.2.4 XML-Formatted Sensor Data String
Each scow event shall be passed as a string on one continuous line of data.
The example below is broken up by variable for ease of reading:

DATE_TIME values shall be formatted as YYYY-MM-DD HH:MM:SS, as shown above.
If, for any reason, a field has no value, the enclosing XML tags should be sent with nothing between them (for example, <DRAFT_AFT></DRAFT_AFT>). The web service cannot handle a "null" value or any other indicators of no value collected.
3.2.5 Contractor Data Backup
The Contractor shall maintain an archive of all data sent to the DQM database during the dredging contract. The Contracting Officer's Representative (COR) may require, at no increase in the contract price, that the Contractor provide a copy of these data covering specified time periods. The data shall be provided in the HTML format which would have been transmitted to the DQM database. Data submission shall be via storage medium acceptable to the COR.
At the end of the dredging contact, the Contractor shall contact the DQM Support Center prior to discarding the data. The DQM Support Center will verify that all data has been received and appropriately archived before giving the Contractor discard permission. The Contractor shall record in a separate section at the end of the scow's onsite copy of the DPIP the following information:
- Person who made the call
- Date of the call
- DQM representative who gave permission to discard
3.3 PERFORMANCE REQUIREMENTS
The Contractor's DQM system shall be fully operational at the start of dredging operations and fully certified prior to moving dredge material on the contract (see Paragraph 1.4, "National Dredging Quality Management Program Certification"). To meet contract requirements for operability, in addition to certification, the Contractor's system shall provide, at a minimum, a data string with values for all parameters while operating, as described within the specifications. Additionally, all hardware shall be compliant with DPIP requirements Paragraph 1.5, "Dredge Plant Instrumentation Plan [DPIP]"). Quality data strings are considered to be those providing values for all parameters reported when operating according to the specification. Repairs necessary to restore data return compliance shall be made within 48 hours. Failure by the Contractor to report the required data within the specified time window for scow measurements (see Paragraph 3.2.2, "Data Reporting Frequency," and Paragraph 3.2.3, "Data Transmission to the Web Service") and failure to receive DQM certification prior to dredging will result in withholding of up to 10% of the contract progress payment per clause 52.232-5.
