Private Locate Disclaimer
Many variables, including, but not limited to age and condition of the facilities in question, soil type, and moisture content can adversely affect the ability of our equipment to find and trace utilities, and on rare occasions may even result in the errors or omissions beyond our control.  Some utilities are simply not locatable.  If we can’t find a given facility, we are confident that no one else can either. 
The more information you can provide about our site, the more complete and efficient our work will be.  For best results, we ask our clients to provide us with the following information when possible:

  • Copies of any available schematics, plans, or as-built drawings (PDF format preferred)
  • At least one on-site contact, including name, title, telephone number and/or email address
  • Access to all utility buildings, mechanical rooms, etc. within and around the area of investigation.
ASI shall not be held liable for excavation related damage to any utility not shown on prints, maps, plans, as-built drawings or other documents provided, or having no serviceable connection point or visible surface structure within the requested area of investigation, and/or the presence of said utility is not otherwise made evident to us before or during the performance of our work.
ASI specializes in locating private utilities NOT owned or maintained by local electric, telecommunications, gas, water, or sewer operators, and we assume no liability for excavation related damage to any utility owned or maintained by public utility providers (e.g. Xcel, Comcast) which are typically be protected by state mandated one-call services.
In the course of our work there are times when we must mark facilities owned by public utility providers in order to eliminate them from our search process.  Marks placed on public utilities to facilitate this process should never be relied upon in lieu of contacting public locators as mandated by state or federal law.
Per 811 Law
Duty of Excavator

(3)(a) Except in emergency situations and except as to an employee with respect to the employer's underground facilities or as otherwise provided in an agreement with an owner or operator, no person shall make or begin excavation without first notifying the notification association and, if necessary, the tier two members having underground facilities in the area of such excavation. Notice may be given in person, by telephone, or in writing if delivered.
Duty of Facility Owner (4)(a) Any owner or operator receiving notice pursuant to subsection (3) of this section shall, at no cost to the excavator, use reasonable care to advise the excavator of the location and size of any underground facilities in the proposed excavation area by marking the location of the facilities with clearly identifiable markings within eighteen inches horizontally from the exterior sides of any such facilities. Such markings shall include the depth, if known, and shall be made pursuant to the uniform color code as approved by the utility location and coordinating council of the American public works association. In the event any person is involved in excavating across a preexisting underground facility, the owner of such facility shall, upon a predetermined agreement at the request of the excavator or the owner, provide on-site assistance. Any owner or operator receiving notice concerning an excavator's intent to excavate shall use reasonable care to advise the excavator of the absence of any underground facilities in the proposed excavation area by communicating directly with the excavator and providing documentation thereof, if requested, or by clearly marking that no underground facilities exist in the proposed excavation area. Owners and operators shall, within the time limits specified in subsection (6) of this section, provide to the excavator evidence, if any, of facilities abandoned after January 1, 2001, known to the owner or operator to be in the proposed excavation area.
