PHMSA-aligned field documentation for pipeline grade verification, compressor station construction, HDD bore records, and right-of-way documentation across the full oil and gas construction lifecycle.
PHMSA 49 CFR Part 192 and Part 195 require pipeline construction to be documented to demonstrate compliance with depth of cover, backfill compaction, and horizontal bore specifications. Missing or inadequate field records are a primary cause of PHMSA enforcement actions.
Horizontal directional drilling bores require documentation of bore path, entry and exit elevations, crossing depth, and final as-built position. Manual bore documentation is error-prone and slow — especially on multi-bore water and road crossings.
Pipeline ROW construction involves clearing crews, grading crews, pipe laying crews, and restoration crews — all generating field records that need to be unified into a coherent as-built package for the pipeline operator and state agency.
Log pipe trench bottom grades at required intervals — verify against design profile and PHMSA depth of cover requirements. Station-based logging with automatic pass/fail against minimum depth specifications.
Document horizontal directional drilling bores with entry and exit coordinates, bore depth at crossing, pipe material and diameter, and final as-built position. Required for PHMSA water body and road crossing records.
Foundation elevation documentation, equipment pad grade verification, compaction records for site grading, and drainage documentation for compressor station and metering station construction.
Log pipeline depth of cover at required intervals — flag locations where cover is less than PHMSA minimums (typically 30 inches normal terrain, 36 inches agricultural, 48 inches at road crossings). Generate cover summary for operator records.
Document ROW clearing widths, grading conditions, topsoil stockpile locations, and restoration progress. GPS location capture for all ROW features — KMZ export for pipeline GIS.
Foundation elevation documentation, equipment setting records, and site grade verification for metering stations and valve settings along the pipeline route.
Log trench backfill compaction tests with nuclear gauge — verify against PHMSA and project specification requirements for compaction in agricultural and road crossing areas.
Daily field safety records, gas monitoring logs, and pre-task safety meetings — required for construction in designated hazardous areas near existing pipelines and facilities.
PHMSA 49 CFR 192.327 requires minimum cover of 30 inches in normal terrain, 36 inches in consolidated rock, 36 inches in agricultural areas that may be cultivated, and 48 inches at road crossings (36 inches if in casing). Navigable water crossings require 48 inches below the river bottom or as specified by the USACE. Sitemark flags pipeline depth shots that fall below your configured minimum.
Sitemark logs the HDD bore with entry coordinates and elevation, exit coordinates and elevation, bore path depth at the crossing centerline, pipe diameter and material, and crossing date. This information is captured in the field and exported in the format required for PHMSA water body crossing records and permit documentation. GPS coordinates at entry and exit points are captured automatically.
PHMSA does not specify a universal compaction percentage for pipeline trench backfill, but project specifications typically require 90–95% Standard Proctor compaction in normal terrain and 95% in agricultural and road crossing areas where settlement must be minimized. State DOT permits for road crossings routinely require 95–100% Modified Proctor. Sitemark logs compaction to whatever standard your specification requires.
Yes. Sitemark covers the field documentation requirements for both natural gas pipelines (PHMSA Part 192) and hazardous liquid pipelines (PHMSA Part 195). The core features — trench depth logging, compaction records, bore documentation, and as-built records — apply to both.
PHMSA requires that pipeline construction records be retained for the life of the pipeline. This includes as-built surveys, welding records, pressure test documentation, and material certifications. Field documentation generated in Sitemark is exportable as PDF and CSV for long-term operator record systems.
Sitemark is designed for land construction documentation — the GPS-based features require GPS coverage to function. For subsea pipeline documentation, the field data logging and report generation features work, but GPS capture will not function on a marine spread.
