Extreme Access specializes in bridge inspection projects and has successfully completed several thousand inspections to date. We have a team of fully certified Lead Bridge Inspectors with from 25 to 5 years of inspection experience. The scopes of work on our bridge inspection projects have included in-depth, routine, fracture critical, inventory, emergency and specialized timber bridge inspections which includes reporting at both the NBIS and PONTIS level. We have inspected bridges in thirteen U.S. states including Alaska and in British Columbia, Canada.
Our reputation is based on the thoroughness of our inspections, the timeliness of our submittals, and excellent communication with our clients.
Our highly skilled climbing team performs inspections on a wide variety of structures where traditional methods of access are not available. Structures have included fire lookout towers, smokejumper towers, communications towers, scenic overlooks, penstocks, spillway gates, warehouse truss systems, historic timber buildings etc.
These inspections include providing detailed reports and recommendations for maintenance and repairs.
SPECIALIZED TIMBER INSPECTIONS
The Extreme Access bridge inspection team has completed several hundred timber bridge and timber structure inspections since 1990. These have included both routine and in-depth inspections of girder, truss, trestle and covered bridge structures; inspections of fire lookout towers, smokejumper towers, scenic overlooks and inspections of beams and trusswork in historic buildings.
In 2004, Extreme Access started offering Resistance Drilling as part of our timber inspection program. The Resistograph performance is based on a micro-drilling resistance measuring method. A steel drilling bit 15” long with a 0.078" diameter penetrates the timber structure at a uniform speed while resistance is measured. The measured resistance data is recorded on a wax paper strip at a scale of 1:1 and printed or captured electronically via bluetooth. This investigative method produces an objective result while the small diameter bit results in minimal damage to the bridge components.
Our climbing team has performed FERC required inspections on over 105 tainter gates and 45 penstocks in the past 5 years.
Material types inspected include concrete, steel, timber, brick, stone and rock. Inspections projects may include Non-Destructive Testing methods including: magnetic particle and dye penetrant and assistance with ultrasound, stress wave and impact echo etc. In addition we can provide coring, dust sampling, Schmidt hammer testing and rebar surveys.
MAINTENANCE AND REPAIR OF BRIDGES AND STRUCTURES
Our climbing team has extensive heavy construction experience and is able to provide maintenance and repair services on a variety of structures.
INSTALLATION OF OSHA COMPLIANT LIFELINES
We have completed several installation projects providing OSHA compliant lifelines on bridges carrying oil and gas pipelines with the intent to provide access for inspection of the pipelines themselves.
DIFFICULT ACCESS INSTALLATION OF MONITORING EQUIPMENT
Our climbing team can install monitoring equipment in difficult access locations.
Extreme Access has a fully certified roped access rescue team, certified through SPRAT and IRATA (Society of Roped Access Technicians/Industrial Roped Access Technicians Association). We are unique in that our fully certified rescue team members are also fully certified inspectors. This supports our goal of having trained inspectors safely inspect even the most difficult locations.
CONFINED SPACE ENTRY TEAM
Our climbing team members are all trained for confined space entry.
GEOTECHNICAL SURVEY ASSISTANCE
With a climbing geologist on staff, backed up by a highly skilled climbing team, we are able to provide geologic mapping on cliff faces, dam abutments, road cuts etc.
TOPOGRAPHIC AND GEOMETRIC SURVEY ASSISTANCE
Our climbing team can assist with surveys by carrying prisms to difficult access locations and providing permanent installations where required.
We are able to provide video and photography services for rapid appraisal of conditions and to supplement client records. If conditions are amenable we can provide live video.
