Executive Summary

The United States Army Corps of Engineers, New York District (USACE-NAN) and the New Jersey Department of Transportation Maritime Division (NJDOT-MD) are deepening the Port Jersey Channel to an elevation of -52ft MLW. The Passaic Valley Sewerage Commission (PVSC) Tunnel crosses the Port Jersey Channel at an elevation of -64±2ft. The channel deepening, from -37ft to -52ft, removed half of the sediment overburden that confined and protected the PVSC tunnel. The USACE-NAN and NJDOT-MD designed the S-PJ-4 contract to dredge the channel and construct the protection for the tunnel. The protection consists of over four hundred and twenty-nine steel plates placed with the top face between an elevation of -52.0ft and -52.5ft. The PVSC tunnel was not to be damaged.

The USACE-NAN selected Weeks Marine Incorporated (WMI) to construct the project.

The plates are 30ft x 4ft x 0.42ft (5”). The allowable gap between the plates was 0.33ft (4”), except in the area where the contractor encountered hard rock. The top of the plates was to be placed below -52.0ft and above -52.5ft. The tilt of each plate must be less than ±2%, with less than ±9.6% confidence interval. The ramp of each plate must be less than ±1%. The contractor placed plates of different sizes (e.g., 15ft x 4ft x 0.42ft) to accommodate changes

The overall construction achieved the objective of protecting the PVSC without damaging it. The four hundred and twenty-nine plates were placed within or near the specified tolerances. Of these four hundred and thirteen were full-sized plates and sixteen were half-sized plates. Some remediation was required throughout the construction. Five remediation plates were added all within the Bayonne triangle. The construction took longer than planned. The complementary report addresses the overall quality control and quality assurance on a 100-plate.1

The USACE-NAN assigned e4sciences (e4) to perform quality assurance. e4 monitored and reviewed the project throughout the construction. For this Task Order #0001 in Contract W912DS-12-D-0002, e4sciences performed the following tasks:

1. Meet regularly with team to discuss progress and issues

2. Review the WMI quality-control surveys

3. Submit USACE-NJDOT quality-control reviews

4. Produce the quality-assurance surveys

5. Submit the quality-assurance report

6. Back check of WMI response

Table ES-1 lists the twenty-one plate groups. A few issues occurred during the construction: (a) disagreement regarding the as-built placement in Bayonne triangle and Global berth, (b) a dropped plate, (c) excavator fell over, (d) rock diggability, (e) a lost plate, and (f) a large boulder outside the protection zone.

In the Bayonne triangle, WMI placed P001-P012. e4 measured these plates with two side-scan sonar systems, sub-bottom reflection seismology with single-beam bathymetry, sonar sector scans, and ROV video images. In the Bayonne triangle, WMI took some time to place plates and to remediate some observed offsets. Five remediation plates were placed. WMI placed R1, R2, and R3 on gaps. P001A and P002A were placed on the side slope.

In the Global berth, WMI placed P012 to P105. Measurements indicated that several plates were at the very edge of tolerance. The contractor evaluated these instances carefully. At P033, the USACE-NAN construction division approved the contractor ripper-tooth soundings as the quality-control survey. For quality-assurance (QA), e4 continued with side-scan sonar and sub-bottom reflection seismology with single-beam bathymetry. The USACE-NAN survey branch continued with multibeam bathymetry as part of the quality assurance.

WMI placed P106-P255 in the northern section of the channel. e4 continued with side-scan sonar and sub-bottom reflection seismology with single-beam bathymetry. The USACE-NAN survey branch continued with multibeam bathymetry. Two concerns arose in this section: (a) the rock area2 between P165 and P189, and (b) rapid sedimentation on P195-P254. P173, P174, P177, P178, and P179A,B are half-sized plates. There are no plates P175 and P176.

WMI placed P256 to P430 on the southern section of the channel. e4 continued with side-scan sonar and sub-bottom reflection seismology with single-beam bathymetry. The USACE-NAN survey branch continued with multibeam bathymetry. WMI found a boulder east of P319. The boulder, just outside the protection zone, was found to be an element of the till. WMI removed the boulder.

The plates in the MOTBY triangle, P410 through P428, were placed parallel to the plates in the channel; that is, they were placed normal to the PVSC tunnel trajectory. P429 and P430 were placed obliquely. P430 provides protection on the slope. e4 observations imply that the construction did not affect the New York Bay Shaft, 100ft to the southeast.

2. Scope of work

The USACE-NAN objective of the S-PJ-4 contract was to complete the deepening of the Port Jersey Channel to -52ft MLW. The first step was to remove the sediment overburden above the PVSC tunnel and to immediately replace the weight with steel overburden. The construction required removal of black silt, then Pleistocene, and then placement of stone bed and steel plates in iterative and sequential manner. The specifications in the construction required careful monitoring to ensure that they were met during the construction. Going back would have incurred a large cost in time and money.

The construction in the S-PJ-4 contract had proven particularly challenging as the project evolved.

This scope provided for weekly review of the contractors signed-and-sealed ripper-tooth analyses, followed by a more focused and repetitive geophysical survey of 40 to 60 plates at a time in order to maintain quality assurance of the construction.

The contractor had encountered rock along the trajectory of the tunnel at locations for P165 to P189. The morphology, foliation, nature and properties of the rock were critical to best action to take with regard to completion of the protection at this location. e4 was to determine the likelihood of further rock outcrops along the trajectory.

The District reviewed and approved all documents before they were released to any party outside the USACE-NAN. All information, documents, correspondence, reports, conversations, meetings, etc. generated under this task order were to be used exclusively for executing this SOW and must have District approval before being released or used for any other purpose.

The A/E was to have communicated with the USACE, New York District Project Engineer daily, informing him of the e4’s location and progress of work during the performance of fieldwork. e4 was to directly coordinate the schedule with U.S. Coast Guard as necessary.

Work under this task order shall be completed within 240 calendar days after receipt of the Notice to Proceed.

2.1 Task 1A: Quality control

e4 was to complete a quality control plan ensuring that the evaluations were accurate, and that the concepts were practical, and that uncertainties and errors were quantified.

2.2 Task 1B: Meetings

e4 was to attend 25 meetings with the PDT.

2.3 Task 1C: Review of contractor QC data log packages and report e4 was to receive every week a signed and sealed package of data from the contractor surveying the plate placement at 20-plate intervals. e4 was to analyze the data for self-consistency. Each point was to plotted in x, y and z. The tilt and ramp were to be assessed. e4 was to examine the NJDOT interpretation of the data. e4 was to produce a report within 24-hours on the contractor plate-placement data including the review by NJDOT and their consultants. The report was to include a map of the ripper tooth data, and plots of the elevations and their range and of ramp and tilt.

2.4 Task 1D: Plate surveys and QA survey report

e4 was to conduct regular QA surveys (every 40 to 60 plates) to ensure that the contractor data was consistent and to back up the multibeam surveys of plate elevations. These surveys were to include but no be limited to side-scan sonar, sub-bottom seismic reflection, ROV imaging, single-beam bathymetry, sector scanning, and ROV sonar imaging. e4 was to describe the findings on the small QA surveys in a report. The report was to show maps, images, and cross sections that test the consistency of the contractor and government surveys.

2.5 Task 1E: Back check

e4 was to have received written response from WMI on the QA report. e4 was to complete the process by making final comments – the back check – on the WMI certification on each plate.

The back check was to incorporate findings from USACE survey branch and QA report.

2.6 Task 1F: Reporting

e4 was to produce a brief report describing the findings as soon as possible after the sample analyses are complete. The report was to include scope, methodology, analyses, cross sections, and maps.

3. Methodology

The USACE-NAN objective of the S-PJ-4 contract was to complete the deepening of the Port Jersey Channel to -52ft MLW. The horizontal coordinate system was New Jersey State Plane (NJSP) NAD 83ft. The vertical datum was NGDV29 MLW at Sandy Hook. The first step was to remove the sediment overburden above the PVSC tunnel and to immediately replace the weight with stone bed and steel plate overburden. The construction required removal of black silt and then Pleistocene sediments. WMI laid the stone bed, and then placed the steel plates in an iterative and sequential manner. The specifications in the construction required careful monitoring to ensure that the specifications were met during construction. Going back to remove more sediment or repair misplaced plates incurred a cost in time and money. Figure 2 shows the steel plates in preparations before the construction. The steel plates are 30ft x 4ft x 0.42ft (5”).

3.1 Task 1A: QA/QC plan

e4 produced a QA/QC plan for each of the tasks. Appendix I contains the plan. The sole purpose of the QA/QC plan was to ensure accuracy in the reviews and reports. The underlying theme was

(a) to acquire redundant measurements to ensure accuracy in the work, (b) coordinate with USACE-NAN survey branch, (c) coordinate with the NJDOT and Parsons Brinkerhoff, the engineers of record, and (d) work with WMI to establish agreement on accuracy.

Timeliness was controlled by the fact that all results were turned around in 24hr.

Communications with the project manager and the stakeholder team occurred nearly everyday, if not more frequently. e4 was in contact with the USACE program manager every day.

Cost control was managed by two facts (1) e4 is a fixed price, lump sum team, and (2) e4 shares the project mission with its clients. Regular communications and good planning kept e4 on cost.

William Murphy 3, the e4 project manager, was responsible daily to make sure that no cost concerns would arise. Once the construction achieved momentum after the Bayonne triangle (~ February, 2012), the project settled into a rhythm where progress and costs were predictable.

3.2 Task 1B: Meetings

e4sciences attended forty (40) meetings throughout the course of the project with the contractor and the NY District. Both the field team and the data processors attended the meetings. The meetings were held to review the results and better understand plans and progress of the plate placement. e4 monitored and ensured contractor quality control during construction.

Before March 2012, e4 attended conference calls roughly one per week. After the rock was discovered to be undiggable with the WMI excavator at P165, e4 participated in every conference call on Monday, Wednesday, and Friday, thereafter, up to sixty calls.

3.3 Task 1C: Review of contractor QC data log packages and report

The USACE and e4 received quality control reports from WMI each week for the set in Table 1, twenty or so plates at a time. WMI certified the results. The QC reports include ripper-tooth measurements for plate elevations, basically nine measurements per plate. Based on these measurements, WMI produced an as-built model for the plate configurations. If the tilt, ramp, or offset were out of or near specifications, Remotely Operated Vehicle (ROV) took photographs of the areas of concern. Every plate was surveyed under these guidelines. Figure 3 is a 3-D representations of tilt and ramp.

The QC reports were delivered to e4 on Thursdays, and were turned around within 24 hours. e4 produced as-built maps. e4 produced self-evident graphs for elevations, tilt, and ramp. NJDOT and Parsons Brinckerhoff (PB) reviewed the WMI QC reports. Their findings were included in the e4 response.

Also included was the multibeam bathymetry of the stone blanket before the plates were placed.

The original plan was for e4 to work with the USACE survey branch and evaluate stone bed.

However, as the contract evolved, contractor took responsibility for stone bed survey. Stone bed was laid 100ft at a time. This area was prepared for twenty plates, and the review was done immediately thereafter. e4 received multibeam surveys of the stone bed from the contractor on a weekly basis for IDC-209 Task Order #0001. e4 reviewed the contractor’s methods of multibeam survey to determine the elevation of the stone bed. Review of multibeam evaluation continued throughout the project lifespan.

3.4 Task 1D: Plate surveys and QA survey report

3.4.1 QA Measurements

As instructed, e4 monitored the placement of stone bed and steel plate placement. The measurements were made while the construction proceeded. e4 mapped areas using high definition side-scan sonar, sonar sector scanning, sub-bottom seismic reflection, e4 single bathymetry, USACE-NAN multibeam bathymetry and underwater close-proximity video. As the project evolved, USACE-NAN Contracting Division adjusted monitoring parameters to expedite the progress of the project.

The horizontal coordinate system was New Jersey State Plane (NJSP) NAD 83ft. The vertical datum was NGDV29 MLW at Sandy Hook.

e4 imaged and measured the placement of and seams between the plates using the side-scan sonar, sector scanner, sub-bottom seismic, single-beam bathymetry and ROV video.

3.4.1.1 Side-scan sonar. e4 executed two completely different side-scan sonar investigations. The 4200-chirp sonar tool was fixed to the hull at -6ft below water level. The survey was conducted at 330kHz and 440kHz. The 4200 survey tracked four planned survey lines along the trajectory of the PVSC tunnel. The lines were measured traveling in both directions.

The second side-scan sonar investigation used a 4125-chirp sonar tool. It was towed at -40ft below water level. This survey was conducted at 660kHz and 1.9MHz. The 4125 survey tracked the same four planned survey lines. The lines were measured traveling in both directions.

3.4.1.2 Sonar Sector Scans. e4 measured the plates with a 2MHz sonar sector scanner. A 5ft tripod holding the scanner was lowered to the bottom. The scans were obtained at 15ft and 30ft range. The position was incremented 15ft to 30ft at a time.

3.4.1.3 Sub-bottom reflection seismology. e4 used a 424-chirp and a 512i-chirp tools. The piezoelectric sources, we chirped at 4 to 24kHz for 5msec and 1 to 10kHz for 5msec, respectively.

3.4.1.4 Bathymetry. The USACE-NAN survey branch measured the bathymetry of the top of plates with multibeam sonar throughout the S-PJ-4 contract. e4 received the multibeam surveys from the USACE-NAN results within a few days of the survey.

e4 measured single-beam bathymetry simultaneously with the sub-bottom profiles. e4 used an Odom Echotrack CDM single-beam system with SMBB200-3 200kHz shallow water transducer.

The sonar properties of the water column were measured with an Odom digibar system. The single-beam results were used only to benchmark the sub-bottom reflection seismology.

3.4.1.5 ROV. e4 performed underwater video of the plates and plate gaps with a Video Ray underwater remotely-operated vehicle (ROV).

3.4.2 Global area, Bayonne triangle P001 – P011 and P012 – P105

After WMI placed the first set (P001-P011), they reported that the plates were placed as planned.

e4’s initial survey indicated otherwise. Surveys were performed over the next several months until remediation was completed. Plates R1, R2 and R3 were placed once P001-P011 had been adjusted. P001A and P002A were placed on the slope to complete the Bayonne triangle protection. Thereafter, riprap from the new Global pier construction covered the Bayonne triangle plates.

Immediately after the riprap was placed, WMI drove piles into the ground for the Global terminal.

Access to the Bayonne triangle area was limited due to the barges and other construction facilities.

Figure 7 shows a side-scan sonar image of the plate in the Bayonne triangle. Figure 8 shows a side-scan sonar image of the driven concrete piles in the water column.

The full suite of measurements continued through to P012-P033. Early in the process WMI determined that multibeam bathymetry on fresh steel plates was not accurate enough to satisfy the specifications. The contractor developed a new method, ripper-tooth sounding survey. At this point USACE Construction Division chose to rely on the contractor’s stone bed and ripper tooth soundings for QC. e4 developed a technique to perform analysis for the stone bed survey and ripper-tooth soundings. QA monitoring would thereafter, only consist of side-scan sonar, sub-bottom seismic reflections, e4 single beam bathymetry, and USACE multibeam bathymetry. e4 would thereafter hold out the sector scans and ROV-video images.

3.4.3 Northern half of channel, P106 – P255

For plates above P106, e4 acquired only side-scan sonar and sub-bottom reflection seismology with single bathymetry. e4 used fewer cross lines normal to the PVSC trajectory and parallel to the long axis of the plates. The USACE-NAN survey branch measured the bathymetry with multibeam sonar.

3.4.4 Rock area, P165 – P189

At P165, WMI encountered rock. The rock was particularly difficult to dig. WMI decided to use an excavator to complete the rock dredging at P165-P189 and postponed this work until July after the rest of the project was complete. e4 measured the rock area with side-scan sonar and sub-bottom reflection seismology supplemented by single-beam bathymetry. The USACE-NAN survey branch measured the bathymetry with multibeam sonar. P173, P174, P177, P178, and P179A,B are half-sized plates. A complementary report for rock3 in this area shows the analysis of the rock. PB analysis of the strength of the rock suggested the half-sized plates would be suffice to maintain the overburden weight in this section. It was also in this area that a plate was lost during remediation. WMI said that plate had been stuck under other plates; e4 could not confirm this assertion.

3.4.5 Southern half of the channel, P255 – P430

For P256 to P430, WMI cut quickly through sediment and rock. e4 acquired side-scan sonar images and sub-bottom profiles after the plates were placed.

3.4.6 MOTBY area, P410 – P430

In the MOTBY triangle, WMI placed P410 to P428 in parallel configuration to the other plates.

P429 and P430 were rotated and placed on the slope. e4 acquired side-scan sonar images and sub-bottom profiles. The investigation focused on the slope and the effect on the New York Bay Shaft 100ft to the southeast from the last plate.

3.5 Task 1E: Back check

At the end of the completion of the plate placement, e4 re-measured the entire project with side-scan sonar. Sub-bottom seismology was used to replace the sonar sector scans and ROV-video images. The sector scans and ROV-video images were held back after the decision by USACE- NAN Construction Division to honor the WMI quality-control surveys. The final survey did not include the P001 through P059 as the access to these plates was limited by WMI barges and construction in the new Global berth.

3.6 Task 1F: Report

e4 compiled the results detailing the subsurface monitoring of the plate placement into this report that briefly describes the principle conclusions, the scope, the methods and the results archived.

The report is complementary to a second report on the overall quality assurance and monitoring throughout construction

4. Results

The project began in July 2011. The construction was completed in August 2012. The original expectation was to be completed by December of 2011. Four hundred and twenty-nine plates were placed on the PVSC trajectory. Of these four hundred and thirteen were full-sized plates and sixteen were half-sized plates. Some remediation was required throughout the construction Five remediation plates were added all within the Bayonne triangle. One plate was apparently lost under other plates. e4 could not confirm the location of the lost plate.

The plates are 30ft x 4ft x 0.42ft (5”). The allowable gap between the plates was 0.33ft, except in the area of exposed rock. The top of the plates was to be placed below -52.0ft and above -52.5ft.

The tilt of each plate (Figure 3) must be less than ±2%, with less than ±9.6% confidence interval.

This condition was introduced during for the ripper-tooth sounding analysis, due to the probability analysis and the short range of the measurements. The ramp of each plate (Figure 3) must be less than ±1%.

A complementary report addresses the quality control and quality assurance on a 100-plate basis.

A few issues occurred during the construction: (a) disagreement regarding the as-built placement in Bayonne Triangle and Global Berth, (b) a dropped plate, (c) excavator fell over, (d) rock diggability, and (e) a lost plate.
