Surveying

Survey is one of the first and last tasks performed on a project. IEPC’s survey crews are involved in the project execution lifecycle from conceptual design to start-up and commissioning.

Before a preliminary route map can be prepared, GPS control points should be set and a preliminary route survey performed to establish the proposed route and affected footprint. The survey data is used to design, permit, bid, and build pipelines and facilities for our clients. Capturing this data is critical as it is used to produce construction alignment sheets, permit drawings, easement plats and engineering detail design drawings. Our integrated process enables essential design data to be extracted from CAD files prior to the start of construction so the  proposed pipeline and facilities can be staked out prior to ensure the design precisely fits the ground as intended in engineering design.

During construction, an as-built survey provides an inventory of all materials installed for future tracibility and can be used subsequently to prepare the final as-built drawings and record information for GIS systems. Owner operators are required to maintain this information for regulatory audits and the operation of their pipeline and facilities. IEPC’s survey services provide reliability for this record information, a critical capability to meet today’s increased emphasis on pipeline safety and integrity.

As your partner, we provide all mapping and surveys to customers’ guidelines, using state-of-the-art technologies such as electronic field books, total station and global positioning systems (GPS). We provide data file formats that can be used in computer drafting and integrated into existing Geographic Information Systems (GIS).

Being part of a multi-discipline firm allows us to offer many cost saving advantages. These synergies increase efficiencies and eliminate hidden third-party coordination costs and delays.

Services include:

  • Route reconnaissance
  • Preliminary and boundary surveys
  • Topographic Surveys
  • River Crossings
  • Construction staking
  • As-built surveys
  • Environmental Support Surveys

Environmental Permitting

Our service offerings are applicable to most projects that require regulatory permitting and include, but are not limited, to:

  • Pipeline routing and facility siting studies
  • Full management and execution of environmental permitting
    • USACE Section 404/10/103
    • FERC 7c and 3a filings
    • USFWS consultation and coordination
    • NOAA/NMFS Consultation and Coordination
    • USEPA Air and NPDES Permitting
  • Phase I Environmental Site Assessments
  • State coastal zone and wetland permitting
  • State wildlife department consultation and coordination
  • State-level air and pollutant discharge elimination systems permitting
  • Sediment and erosion control plans and permitting
  • Water use and discharge permits
  • State historic preservation office consultation and coordination
  • County- and parish-level environmental permitting and coordination
  • Municipal-level environmental permitting and coordination

As an added benefit to your project, our team of environmental professionals works closely on a daily basis with our project managers and engineers, so project design and environmental constraints and permit conditions are fully integrated, capturing synergies that are not available when projects are executed in a phased approach within discipline silos.  Conducting environmental planning concurrently with engineering design usually provides favourable outcomes and greater success in completing projects within budget and on schedule.  If preferred, the permit services group can operate autonomously from any other services provided by IEPC.  You choose the services your project needs.

IEPC’s permit services group has the knowledge, experience and expertise to take your project from concept to completion.

 

Pipeline Mapping

IEPC’s pipeline mapping team provides precision mapping design for all engineering and field services needed to acquire right of way (ROW), environmental and non-environmental permits, and to produce required alignment sheets for environmental, construction, bidding and as-built.

Our mapping team  utilises data from civil surveys done on the project site to produce FERC and construction alignment sheets, issue for bid alignment sheets, as-built alignment sheets, and  environmental and non-environmental permits, row acquisition easement plats, construction drawings, and as-built drawings.

Our services include:

  • FERC filing alignment sheets and support drawings
  • Environmental permits
  • Non-environmental permits
  • ROW acquisition easement plats
  • Construction drawings
  • As-built drawings

Maximum Allowable Operating Pressure (MAOP) Validation

Maximum allowable operating pressure (MAOP) standards have already begun to be implemented by some US states, and are soon to be implemented in more.  IEPC has been working with clients to get these standards in place through document research and spreadsheet documentation for all existing pipeline assets.

GIS/MAOP validation is becoming one of the most prioritised goals for pipeline companies. As federal safety standards for gas pipelines have recently been passed, compliance for operators includes the retrieval of records that evaluate potential corrosion or unsafe design pressures.

IEPC’s GIS team strives to ensure the safety of your assets and compliance with new legislation regarding gas pipelines by the US Department of Transportation (DOT) and Pipeline & Hazardous Materials Safety Administration (PHMSA). The most recent guidelines for energy companies drafted by PHMSA are regarded under Title 49 Code of Federal Regulation (49CFR) Section 192.619(a), which addresses four broad areas of concern:

  • Design records and pipe fittings’ yield strength
  • Strength test pressure recordings
  • History of a pipeline operating pressure prior to the passing of the Nov 12, 1970 federal ASME guidelines
  • Maximum pressure safely allowed considering the pipeline’s history and current operating records

The final product for many pipeline companies has been to establish a proper MAOP along with undisputable records to justify operating at these pressures with proven supporting documentation that satisfies current and probable future legislation by PHMSA and federal pipeline regulations.

Specialised personnel trained in evaluating pipeline records pinpoint exact locations of critical pipeline attributes, enabling clients to determine measurements of safety with relation to updated federal guidelines.

Clients benefit from the vast depth of experience and from the expert assistance GIS specialists provide in compiling, interpreting and maintaining records that are traceable, verifiable and complete. We provide the following services:

  • Modern software documentation to validate safety and management of pipelines, fittings, and surrounding infrastructure, including services and staff to incorporate the validated pipeline assets into the preferred GIS database schema.
  • Supply of talented individuals with the capacity and flexibility to meet deadlines as and when required.
  • Web mapping based on existing GIS databases and platforms to support MAOP validation and asset management.
  • Delivery of research, retrieval and analysis of all client-supplied historical data including purchase/as-built documentation and strength test reports.
  • Calculation and assessment of pipeline design factors and MAOPs, while offering cost-effective solutions and engineering craft to resolve existing design flaws.
  • Quality assurance by traveling to the client’s home base for consulting, and facilitating professional reviews for final target objectives. GIS provides dedicated employee focus and professionalism toward meeting your company’s needs.

IEPC’s ultimate goal is to support our client with any and all functions of the project, upholding integrity and client confidentiality, principles on which the company was founded.

Integrity and Regulatory Compliance

Pipelines and facilities operators are committed to an error-free, spill-free, and incident-free operation of the oil and gas infrastructure to prevent adverse effects on the public, employees, the environment, and property. In support of this commitment, IEPC assists with the implementation and execution of the integrity management plan (IMP) to maintain the structural integrity of the oil and gas infrastructure that could affect high-consequence areas (HCAs).

IEPC has experience writing and implementing the IMP to comply with the DOT/PHMSA requirements set forth in the Code of Federal Regulations for hazardous liquid pipeline integrity management in high-consequence areas (49 CFR 195.452).
