PND | CORPORATE PROFILE

PND’s roots in Alaska put the firm at the forefront of Arctic engineering. Our vast Arctic experience stretches from Russia through Alaska and into Canada with projects on land and offshore. We routinely design for the severe environmental conditions required for projects in the Arctic, including heavy snow loads, both continuous and discontinuous permafrost conditions, moving ice loads, and working in temperatures below -40° Celsius/Fahrenheit.

Our broad Arctic experience has emphasized the importance of dealing with a host of critical issues such as cold-temperature material fracture toughness; design in saline and freshwater ice environments; the effects of spring breakup on rivers for both flooding and bridge design; remote access utilizing ice roads; construction logistics associated with the Arctic; and foundation design in permafrost. The Arctic is a very unforgiving place where experience and knowledge are critical for successful developments.

Specific areas of expertise in Arctic engineering include: Structural building and bridge design Site civil design and Arctic roadways Arctic hydrology Arctic airstrips Permafrost remediation Foundation design Marine facilities Ice/structure interaction Material fracture toughness at cold temperatures Ice roads and pads Construction and site access logistics Ice modeling

Coastal Engineering

PND offers hydrologic and hydraulic analysis in both freshwater and marine environments, including hindcasting, wave analysis, open channel hydraulics, computer modeling, ice mechanics, erosion control, river training structures, fish passage, and storm drain retention analysis.

Coastal engineering is focused on the shoreline, where water meets the land. The effect of tides, waves, and currents in sensitive marine environments can involve relatively large uncertainties and very demanding project and permit requirements. PND has designed shore protection, wetland restorations, large rubble mound breakwaters, soft shoreline protection, outfalls, vertical wave barriers, floating breakwaters, wave deflectors, and beach nourishment, all of which apply the specialized knowledge of coastal engineers.

Our geotechnical engineers provide soils investigations, seismic analysis, and geotechnical design for both onshore and offshore projects such as: roadways, dams, bulkheads, retaining walls, buildings, bridges, breakwaters, docks, float systems, dredging, and mooring and ballasting structures.

Construction engineering is an unconventional application of classic engineering methods to the often peculiar and unusual situations that arise during construction of marine, bridge, and civil projects. PND has the rare skill set required to develop effective solutions for one-of-a-kind problems.

Research & Development

Transportation EngineeringPND provides transportation engineering services for roads, bridges, trails, railroads, and airports. Our services include road and bridge design; roadway widening; pavement design; drainage; parking facilities; bridge inspection and repair; track realignment studies; and design of airport facilities such as runways and taxiways.

In the early 1980s PND’s founders developed two technologies that revolutionized their niche in marine and civil engineering – the OPEN CELL SHEET PILE® structure and SPIN FIN® piles. The OPEN CELL® system is a retaining wall system that can withstand most sediment and environmental conditions, often at a greatly reduced cost compared to traditional wall designs. SPIN FIN piles are steel pipe piles fitted with unique “fins” that allow the pile to anchor itself into the ground, providing superior tension and compression capacity. PND holds patents on OPEN CELL SHEET PILE system: U.S. Patent No. 6,715,964; U.S. Patent No. 7,018,141; U.S. Patent No. 7,488,140; and U.S. Patent Application No. 12/879,997.

More recently, PND’s in-house researchers have developed the technology for partially penetrating wave barriers, allowing less in-water friction, which increases the circulation of water and sediments around a harbor as well as encourages the movement of sea life.

PND regularly investigates and tests a variety of innovative designs to provide our clients with cost-effective solutions and to expand our market. Our research has included: ice mechanics, ice breaking and resisting structures; floating and partially penetrating wave barriers; permafrost research for improvements of roads and foundations; pile driving attenuation in water; and marine and sediment filtration. We also continue to improve on our OPEN CELL and SPIN FIN technologies.

Our Strand Bridge® system uses epoxy coated or galvanized steel tendons in a unique configuration of horizontal and catenary strands to provide efficient support for spans up to 400 feet. Structural support comes from a combination of beam action of the horizontal and vertical strands connected to back stays and anchored with soil or rock anchors. PND holds a patent on the Strand Bridge system: U.S. Patent No. 6,530,101.

Our experienced surveyors provide bathymetric, topographic, and design surveys, as well as base mapping, in support of a wide variety of projects. Survey services also include: boundaries; land and tidelands; photogrammetric control; retracement; and Record of Surveys and Subdivision Plats.
