1. PROJECT SCOPE AND SCHEDULE

1.1 Scope

Execute a subsurface utility verification and tracing exploration using multiple complimentary measurement methods (e.g., Electrical Resistivity/Electrical Magnetic (ER/EM), utility line locator, video inspection/sonde where utility depths require, ground penetrating radar (GPR), as well as direct visual inspection to locate known and suspected exterior utilities, and assess the presence of exterior utilities in an approximately 5.5 acre portion of the Natick U.S. Army’s Soldier Systems Center’s (NSSC) access control point (ACP), Natick Massachusetts (MA) (Figure 1). Features observed in the data that may impact subsurface construction shall also be identified (debris, buried foundations, bedrock surface, and unknowns), and the boundaries of major lithologic or fill units.

The primary intent is to complete the subsurface utility verification and tracing exploration, identify potential buried debris and foundations, and secondarily to assess shallow geologic conditions before NSSC begins ACP final design. The USACE and the NSSC facilities team have developed an AutoCAD utility location map for the area of interest based on land survey results to date of vault, manhole, and valve cover locations. This map is the base map for this PWS and its deliverables (see Section 9 and 10). Connections between buildings and the mapped utilities must be assessed. While the building interior utilities are not a part of this exploration, all building and facility mechanical and utility rooms must be a component of the exploration effort for exterior underground utility mapping explorations as part of this PWS. In addition to the ACP area, the water and electric lines in front of Building 15 are also to be located using methods indicated above, specified herein and field located. The Contractor should assume 250’ section of these utilities should be located. This line was installed using horizontal directional drilling methods. The approximate location of this line is shown on the plan included in Appendix B. A separate utility plan shall be provided by the Contractor immediately following the field effort.

The depth of the gravity sewer sloping from the west to the east across the site (see Figure 1) should be considered when determining which utility locating methods to employ.

Horizontal precision and accuracy for all utility-tracing data points shall be less than or equal to 1 foot. Vertical accuracy (estimated depth to top of utility or feature) for all utility-tracing data points shall be 1 foot; greater where limited by the measurement method and clearly identified as such.

1.2 Schedule

The performance work statement’s (PWS) intent is to complete all work within 120 days of award (Table 1). The Contractor shall include a schedule with their work plan, with at least one alternative schedule window to allow for bad weather and site schedule constraints.

An optional site visit walk will occur on September 17, 2019 at 9:30 am EDT, and is a good opportunity to understand site logistics including topography, traffic, and security constraints on this project. Those attending the site visit must coordinate access with the USACE project manager and FAX their information to NSSC by September 13, 2019 (see Section 2.1.1).

3. PROJECT BACKGROUND

3.1 Site History

In the mid-1950s, the Army purchased the property that essentially encompasses this entire peninsula (ICF, 2008). Prior to the 1950s, area north of Kansas Street (Figure 1) was a gravel pit operated by the Town of Natick. During that time, there were various operations consistent with sand and gravel, including cutting of vegetation, filling and potentially the creation of construction debris. In 1954, the Army purchased the land and began to develop it. Private homes within the ACP area were removed, and the foundations are reported to have been left in place. The Army built the ACP with commercial and military entrances, which have changed configurations over time.

3.2 Site Conditions

The ACP contains a mix of modern and Cold War-era office buildings and infrastructure, some of which pre-dates 1950. The ACP is being replaced by a modern system and facilities designed by USACE (Figure 1, Table 2). A chain link fence separates the installation from the commercial road north of the ACP. The investigation area is bounded to the east by the Lake Cochituate shoreline and to the north by General Greene Avenue. The ACP area is NSSC’s primary vehicle access point for several hundred employees and supporting contractors each day.

Most of the utilities in the study area are thought to be underneath existing roadways, and to a lesser degree in the grass and tree areas between the roads. Trees between Bldg 39 and 92 have laterally extensive root systems, potentially reducing GPR data quality (Figure 1 and Appendix A). The land surface between Lot C and the Knowlton Gate slopes to the south, with a change in elevation of approximately 30 feet. One or more areas may be more challenging to establishing a grid due to narrow workspace or vehicle traffic hazards (e.g., land between the security fence and General Greene Avenue).

Potential utility materials include, but are not limited to, cast iron, plain or corrugated steel, bituminized fiber, plain/corrugated/wrought iron, asbestos-cement, concrete, vitrified clay, polyvinyl chloride plastic (PVC), acrylonitrile-butadiene-styrene (ABS), and reinforced plastic mortar (USACE, 2006). Some utilities, such as fiber-optic communication lines, may not have metal tracing tape. Buried foundations suspected to be present near General Greene Avenue may contain varying amounts of fill debris including, but not limited to, boulders, metal, and/or masonry debris.

The utility lines to the east of Building 15 (approx. depth is indicated in Appendix B) are to be located both horizontally and vertically to the precision of other utilities as described herein.

3.3 Geology and Hydrogeology

Glacial outwash sand and gravel deposits thicken southward from 5 to over 30 ft, and are underlain by fine to medium sand (ICF, 2008). Fine sands are common under the site, with discontinuous layers of peat, cobbles, coarse sand, and clay. Fill material is likely present over

Table 2. ACP area building utility summary. Building gutters discharge to stormwater system under parking lot and driveways. Appendix B and D available upon request by successful Contractor.

8 Sep-19 former foundations and near current buildings. Road-base fill underlies parking areas and roadways. Regional depth to bedrock is 155-199 feet below grade (Appendix C).

Groundwater is expected to be 13-20 feet below grade where not affected by leaking water utilities or near Lake Cochituate (USGS, 2017, MacTec, 2011). Two monitoring wells with locations and boring logs are on site (Figure 1, Table 3, and Appendix C). Additional wells and boreholes are present (see map and logs in Appendix C), and will by surveyed by USACE for consistency, and positional data provided to the contractor (see Section 4.6 and Appendix C).

3.4 Existing Positional Control and Utility Tracing

USACE established a positional control the MA NAD83 horizontal and NAVD88 vertical datum (Figure 1, Table 3). The survey team also located some visible manways, vaults, and exterior pipes, and were used to update the Northern Industrial Campus utility maps. Current as-built and record drawings show where utilities enter or exit a building, but their location below grade ranges from confident to unknown. These maps (Appendix B, D) are FOR OFFICIAL USE ONLY (FOUO), and available upon request (see Section 7). The FOUO AutoCAD-compatible file used to as the basemap for this project containing all of the utility information to date shall be transmitted at contract award.

Where a geophysical method does not achieve the desired penetration depth (e.g., thick root zones around mature trees), an alternate method shall be employed (e.g., cart-mounted magnetometer). Areas where data quality suffers due to site conditions/logistical constraints and features that cannot be overcome by reasonable field coordination will be clearly identified as soon as possible while in the field and will be clearly identified on all deliverables.

4.2 Site Clearing and Survey Obstacles

The majority of the site is paved, mowed grass, or equipment and material staging areas (Figure 1), so no clearing and grubbing is required for instrument access.

Some temporary vehicle barriers may be moved in advance of the utility tracing, but must be identified during the Pre-Work Meeting. Areas where parked cars or trucks will interfere with utility tracing that cannot be mitigated with weekend or of-hour/evening work must also be identified during the Pre-Work Meeting to coordinate alternatives for NSSC personnel. If off-hour/evening work is anticipated then this must be clearly identified during the Pre-Work Meeting as well as Work Plans and Safety Documents.

4.3 Requests for Information

Direct all requests, to include copies of FOR OFFICIAL USE ONLY information and other than regular workday access, to the Project Manager, Robert Leitch, at 978-318-8033 or Robert.A.Leitch@usace.army.mil.

An AHA shall be submitted for each major phase of work (see Appendix F). A major phase of work is defined as an operation involving a type of work presenting hazards not experienced in previous operations or where a new subcontractor or work crew is to perform the work (e.g., mob/demob, utility tracing method 1, utility tracing method 2, work between the security fence and General Greene Avenue). The analysis shall define all activities to be performed, identify the sequence of work, the specific hazards anticipated, and the control measures to be implemented to eliminate or reduce each hazard to an acceptable level. Work shall not proceed on a phase of work until the AHA has been accepted by the GDA. A preparatory meeting shall be conducted by the contractor to discuss the AHA contents with all engaged in the activity.

The preparatory meeting shall be conducted by the prime contractor and shall include all subcontractors and Government on-site representatives. The AHA shall be continuously reviewed and revised to address changing site conditions or operations as appropriate.

5.3 Accident Reporting

All accidents and near misses shall be investigated by the Contractor. All work-related recordable injuries, illnesses and property damage accidents (excluding on-the-road vehicle accidents), in which the property damage exceeds $5,000.00, shall be verbally reported to the GDA and USACE PM within 4 hours of the incident. Serious accidents as described in EM 385- 1-1 Section 01.D shall be immediately reported to the GDA and USACE PM. ENG Form 3394 shall be completed and submitted to the GDA within five working days of the incident, and CC Robert Leitch (USACE PM) (see Appendix F).

The Contractor shall complete the attached “USACE Contractor Monthly Summary Record of Injuries/Illness and Work Hour Exposure” (for prime and its subcontractors) and forward the completed form to the GDA no later than close of business on the 5th calendar day of the following month. The method of transmission by the prime contractor to the GDA shall be electronically, and CC Robert Leitch (USACE PM).

b. Working knowledge of construction safety procedures as well as Federal and state occupational safety and health regulations;

c. 10-hour OSHA Construction Safety certification or as an equivalent, 10 hours of formal construction safety and health training covering the subjects of the OSHA 10-hour course.

6. UTILITY GEOPHYSICS REQUIREMENTS AND OBJECTIVES

6.1 General Requirements

Design and execute a geophysics and underground utility mapping based utility exploration using a minimum of three complimentary methods and a workflow accounting for the given and existing site conditions (see Sterling and others, 2009). All geophysics and utility mapping data shall be geo-tagged as it is collected. Follow-up QC positional data collection is encouraged, it shall not be used as a substitute for geo-tagging the geophysics data.

The Contractor shall use the latest versions of all data acquisition, processing, and presentation software used to execute this PWS to maximize software interoperability. This includes, but is not limited to, AutoCAD, report preparation software (Adobe Professional, Microsoft Office), and supporting data collection, processing, and interpretation software.

6.2 Goal and Objectives

The intent of this Performance Work Statement is to verify the existing subsurface utility information as well as fill in underground utility data gaps in advance of upcoming construction in an approximately 5.5 acre portion of the Soldier System Center’s ACP. The objectives are to:

Locate, estimate the depth to utility top and diameter, of known and suspected utilities.

Identify potential buried foundations, debris, bedrock, boulders, or other unidentified features potentially affecting new utility or foundation construction, and estimate extent and depth to top of feature.

Interpret the stratigraphy up to 15 feet below grade (correlated to available boring data).

6.3 Site Features

Site features shall be used to create known points supporting geophysics data interpretation and underground utility mapping. The following minimum features shall be measured by employing industry accepted methods for tying in the positional and elevation data to the established benchmark(s). The team assigned to determining the positional data shall have past experience performing this type of work. The resulting data shall have a maximum horizontal error equal to or less than half the precision standard required for the geophysics data:

Invert elevation and location. Estimate the utility diameter and direction where accessible.

14 Sep-19

Building corner location and elevation within and bounding the study area

Pavement patches or other linear cracking which may correspond with utilities within the study area

Monitor wells and soil borings where found

6.4 Data Quality Objectives

The Contractor shall follow and meet the data quality objectives discussed below (United States Environmental Protection Agency, 2006). In some cases, the data quality objective will need modification based on field results. In many cases, measurement device specifications and use define these objectives. Where data quality objectives are modified based on field results, the data and evaluation leading to the change shall be fully documented in the report. The Contractor is encouraged to generate and meet additional data quality objectives where they support the project goals and objectives.

Quantifying the exploration’s horizontal and depth precision and accuracy are two primary data quality objectives governing survey design, execution, data processing & interpretation, and reporting. Consistently following manufacturer’s guidelines SOPs yields consistent or more accurate data and interpretations (Figure 2c). Incorporating known positional features (monitor wells, already mapped utilities) and their response increases survey precision (Figure 2d).

A. State the Problem/Identify the Decision

What is the Data’s Horizontal Precision and Accuracy?

What is the Data’s Depth Precision and Accuracy?

Data Processing Anomaly Resolution. What process or workflow will be used to verify an anomaly is a utility instead of buried building debris?

Figure 2. Graphical depiction of accuracy and precision, showing effects of internally consistent data (2c), and incorporating known features (2d).

15 Sep-19

Geophysics Profile Intersection Mismatch. Is it the result of a modeling assumption, positional data error, or other factor?

B. Identify Decision Inputs

Horizontal Precision and Accuracy. Measured accuracy and drift of the GPS data collection system, satellite availability, system capability.

Depth Precision and Accuracy. Measurement method, GPR velocity profile at boring with a detailed geologic log, water table depth at the time of survey.

Data Processing Anomaly Resolution. Location of utilities entering a building, nearby manways.

Geophysics Profile Intersection Mismatch. What is the vertical difference between the two interpreted surfaces or range of velocities? What were the model input values for each profile? Other factors driving mismatch (e.g., steep topography, software limitations)?

C. Identify the Study Boundaries.

Horizontal Precision and Accuracy. Positional control extent and area of interest.

Depth Precision and Accuracy. No deeper than the water table.

Data Processing Anomaly Resolution. Location of known utilities, pavement patches, cultural features.

Geophysics Profile Intersection Mismatch. Lateral and lowermost data model boundaries.

Internal boundaries may occur within overburden units (where resolvable).

D. Develop Decision Rule/Limits of Decision Errors

Horizontal Precision and Accuracy. 1.0 feet for utility tracing.

Depth Precision and Accuracy. 1.0 feet and the measurement method limits.

Data Processing Anomaly Resolution. Anomalies potentially representing utilities must be consistent across two location methods, match pavement patches or manways, and/or match exterior utility (e.g., gas meter).

Geophysics Profile Intersection Mismatch. Where topographic changes make models diverge at profile intersections, differences greater than 1 ft in the upper 10 ft necessitate re-running the models to improve internal consistency across all of the data sets.

E. Optimize the Design

Horizontal Precision and Accuracy. Alter operating procedures to accommodate site conditions.

Depth Precision and Accuracy. Use an alternate monitor well or soil boring location to obtain velocity profile data, or alternate measurement method.

Data Processing Anomaly Resolution. Evaluate supplied utility plans, building as-built drawings.

Geophysics Profile Intersection Mismatch. Evaluate site conditions and artifacts introduced by the modeling process.

7. ASSUMPTIONS

AutoCAD Utility Deliverable. Contractor adds interpreted utilities locations to the supplied AutoCAD Site Plan File and submits with draft and final report.

Building Access for Utility/Cable Locator Connections. Available, but must be coordinated in advance through USACE.

16 Sep-19

Geologic Boundary Picks. Minimum number of points includes profile intersections, and sufficient number of data points between profile intersections to characterize the change in boundary elevation.

Geophysics Data. All are simultaneously collected with GPS data.

GPS Satellite Coverage. Varies from excellent to problematic. Topography may reduce RTK base station reception.

Grid Spacing. Five foot centers unless site conditions dictate a smaller spacing.

Interior Data. While building interior utility mapping is not a component of this PWS, all building utility connections are a mandatory mapping point and connection to the exterior mapping effort needed for this utility verification and trace PWS.

Positional Data. Contractor establishes GPS base station where feasible, and uses differential GPS where a base station is not feasible. All data is collected and processed in accordance with EM 1110-1-1003 (USACE, 2011) using USACE surveyed benchmarks, control points, and features.

Power. None is available on site.

Site Visit. If attending, the Contractor’s field team leader shall be present.

Residual Hazardous Waste Conditions. None known at ground surface.

Snow. Parking lots, roads, and sidewalks will be plowed. Snow pile remnants may be present.

Subcontractors. USACE encourages use of specialty subcontractors where it optimizes the technical products and minimizes price and schedule problems (e.g., video inspection/pipe locator services).

Unexploded Ordnance. None found or anticipated.

Work Hours. Regular work hours are Monday through Friday, 0700-1800. Holiday and weekend work is encouraged to minimize traffic hazards, lost time, and holiday areas. Other than weekday, work must be coordinated at least two weeks in advance of mobilization through the USACE project manager.

8. OPERATIONS, FUNCTIONS CHECKS, AND REPEAT PROFILES

8.1 Operation, Functions Checks, Quality Control

This PWS section is not a substitute for the geophysics team’s internal and equipment-unique checks and field standardization, and vendor specifications. All equipment shall undergo quality control checks, with the results summarized and included with the final report, along with a discussion on how the results affect data quality, measurement uncertainty, and limitations.

8.1.1 Pipe and Cable/Sonde and/or video/sonde Locators

Verify the unit’s signal does not conflict with site operations. Using existing located utilities, verify the signal at the selected frequency passes into the conductor, successfully propagates along the conductor, and is detected by the receiving antenna. Signal frequencies shall be included in the Work Plan and will be approved by the Installation before mobilization.

17 Sep-19

8.1.2 GPR

GPR data will be collected consistent with ASTM standard 6432 (2005) and the Contractor’s SOP using a common offset mode. Assuming suitable reflectors are present in the common-offset data, GPR energy propagation velocities will be determined using the common mid-point (CMP) method. The CMP data shall be processed to determine GPR energy propagation velocities using X2-T2 or semblance methods. GPR energy propagation velocities shall be used to estimate the depth of reflectors present on the GPR profiles and for other processing and QA/QC purposes. Spatial and waveform sampling frequencies shall be selected to ensure proper waveform recording and subsurface structural imaging.

System operating performance will be tested by conducting airwave walk-away tests at the beginning and end of each field day. This test will be used to confirm system operation stability and to ensure the sampling frequency used to record the GPR data is known and remains stable during data acquisition.

The following procedures shall be used at a minimum, augmented by the geophysics Contractor’s internal SOPs (after Kirsch, 2006, Milsom, 2003, USACE, 1995):

Travel Time and Ground Truth Data. Measure at least one transect through 1-2 existing borings or piezometers for depth and travel time quality control. Where existing piezometers or wells are present, USACE will collect water levels just before or after completing the data collection as required.

Noise and Filtering-1. Minimize filtering during data acquisition, and eliminate noise from portable electronics (radios, smart phones).

Time Zero. Calculate and apply time zero correction

Noise and Filtering-2. Filter receiver electronic noise and system ringing before applying bandpass filters

Gain. Apply amplitude equalization using gain controls best matching site conditions (do not assume automatic gain control will suffice)

Corrections. Apply static and dynamic corrections as warranted by the data and site conditions

Travel Time to Depth. Convert two way travel time to depth using site data such as water table elevations and results from nearby borings or piezometers provided to the Contractor by USACE.

8.1.3 Time and Frequency Domain Instruments

Execute using ASTM guides (ASTM 2011, 2008, 2007), and Table 5, adjusted for site conditions and utility/utility conduit depths and materials.

8.1.4 Magnetometer

Verify the unit can detect a known buried culvert or large diameter utility and a surface object (trailer hitch ball, well cover), and its geo-tagged location is within project requirements).

Assess proximity limits to metal structures and impacts from solar flares and diurnal magnetic field fluctuations.

18 Sep-19

8.1.5 GPS

See Table 5.

8.2 Repeat Profiles

A minimum 50-foot long path shall be established at the site to daily test all positional and geophysical equipment, and demonstrate repeatability (see Table 5).
