In-Pipe Mapping to Accurately Map (3D) installed pipe prior to tie-in. Using Inertial Navigation Systems or commonly called Gyroscopic Mapping, we can provide the most accurate plan/profile for pipes and conduits.
State DOT's are "requiring Design-Build Contractors to create an integrated 3-D model of the existing condition including existing ground surface and subsurface elements and infrastructure (including, but not limited to, drainage structures, utilities, bridges and wall foundations), utilizing data from LiDAR, SUE, field surveys, and existing plans (as-built) data collection."
Gyroscopic Mapping RESOLVES utility conflict and avoidance, ASSISTS in damage prevention, and SUPPORTS permits (USACE 408).
This service provides complete confidence of the position, depth, and geometry of the pipe. Our tools and process are easily added into the construction project.
With the availability of DRONE imagery / video + profiling, the pipeline corridor is monitored during the construction project. From preliminary to final phases, and every stage in between, digital reports are provided on daily, weekly, or event driven schedules to provide the most accurate and detailed reporting.
Inventories, progress, with; supply, crew, and equipment locations, ground conditions, supporting damage assessment, environmental, and landowner resolutions. This program is designed that best serves project management and reporting, available through a Web Portal for immediate client access and analysis.
With the LiDAR profiling available, a complete digital elevation survey of the corridor is provided. This greatly supports compliance and damage prevention programs.
Reduced risk and cost vs Aircraft patrol methods.
The primary objectives of P4D’s inspector involved in construction monitoring on an HDD installation, are to assist in the interpretation of the contract & design documents and to document conformance, or non-conformance, by the HDD contractor.
Our inspectors document their observations and actions throughout the program. Should a question or dispute arise after the installation is complete, the inspector’s notes may provide the only source of confirming data.
Since a drilled installation is typically buried with deep cover under an inaccessible obstacle, its installed condition cannot be confirmed by visual examination.
In 2025, P4D will present existing partnerships to expand the role we provide supporting the needs of our growing Client Base.
In this Market driven response, we're bringing combined expertise to provide a seamless experience for our clients. There's added value in efficiency, quality, and continuity.
