Subsurface Utility Clearance
<br /> Management Program 2.9
<br /> 1. PURPOSE
<br /> Roux Associates, Inc. and its affiliated companies, Roux Environmental Engineering and Geology, D.P.C.,
<br /> and Remedial Engineering (collectively, "Roux"), have instituted the following program for completing
<br /> proper utility mark-outs and for conducting subsurface clearance activities. This establishes a method to
<br /> ensure, to the greatest extent possible, that utilities have been identified and contact and/or damage to
<br /> underground utilities and other subsurface structures will be avoided. For the purpose of this program, a
<br /> structure is defined as any underground feature that may present a potential source(s)of energy, such as,
<br /> but not limited to, utility vaults, bunkers, piping, electrical boxes, wires, conduits, culverts, utility lines,
<br /> underground tanks, and ducts.
<br /> 2. SCOPE AND APPLICABILITY
<br /> The Subsurface Utility Clearance Management Program applies to all Roux employees, as well as their
<br /> contractors and subcontractors. Employees are expected to follow this program for all intrusive work
<br /> involving Roux or other personnel (e.g., contractors, subcontractors) working for Roux, unless the client's
<br /> requirements are more stringent. Intrusive work activities can include, but are not limited to, digging or
<br /> scraping the ground surface, including, but not limited to, excavation; test pitting or trenching; soil vapor
<br /> sampling or the installation of soil borings, soil vapor monitoring points and wells, or monitoring wells; and
<br /> drilling within concrete slabs on grade.
<br /> Deviation from the program, regardless of the specific work activity or location, must be pre-approved based
<br /> on the client's site knowledge, experience, site conditions, and additional documentation on the site. Any
<br /> exceptions shall be documented through the Roux Subsurface Utility Clearance Variance Form, located
<br /> within the Roux Health & Safety Online Application or via OKTA. Approval is required from the Project
<br /> Principal(PP)and the Operations Manager(OM), in consultation with the Office Health and Safety Manager
<br /> (OHSM) or Corporate Health and Safety Director (CHSD), prior to mobilization. Depending on the work
<br /> location, more stringent federal, state, local, or client requirements may apply. It is the responsibility of the
<br /> Project Team to identify such requirements prior to mobilization.
<br /> 3. PROCEDURES
<br /> 3.1 Before Intrusive Activities/Job Planning Process
<br /> Prior to intrusive work at a site, the Project Manager(PM)shall ensure that the notification of the State One
<br /> Call or equivalent service (Nationwide-811) is completed a minimum of 48-72 hours (One-Call State Law
<br /> Directory) before intrusive work activities (this timeline excludes Saturdays, Sundays, Legal Holidays and
<br /> 811 observed holidays). This notification is required by law for all states. State-specific or local laws related
<br /> to utility location may vary. The project team is responsible for understanding requirements that may affect
<br /> their work site.
<br /> Obtain, review, and field verify relevant historical site data that may include: as-builts/site plans;
<br /> easement/right-of-way information; historical aerial photos/development plans; local/state permitting
<br /> records; previous site investigation/boring logs; and/or interviews with site representative/client. Interviews
<br /> with site or client personnel should ask the following:
<br /> • Employee(s) Name and Relationship with the site;
<br /> • Types of utilities, including structure and location of utilities on-site;
<br /> • Depth of known utilities; and
<br /> • Any other relevant information as it pertains to the site.
