Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways.
Moosonee is a town in northern Ontario, Canada, on the Moose River approximately 19 km (12 mi) south of James Bay. It is considered to be "the Gateway to the Arctic" and has Ontario's only saltwater port. Nearby on Moose Factory Island is the community of Moose Factory to which it is connected by water taxi in the summer and ice road in the winter.
Earthworks are engineering works created through the processing of parts of the earth's surface involving quantities of soil or unformed rock.
Wolfe Island is the largest of the Thousand Islands, and is located at the entrance to the St. Lawrence River in Lake Ontario. It is a piece of land situated between Kingston, Ontario and Cape Vincent, New York. Wolfe Island is included in Frontenac County and the Township of Frontenac Islands. The largest settlement on the island is the village of Marysville.
Seabed gouging by ice is a process that occurs when floating ice features drift into shallower areas and their keel comes into contact with the seabed. As they keep drifting, they produce long, narrow furrows most often called gouges, or scours. This phenomenon is common in offshore environments where ice is known to exist. Although it also occurs in rivers and lakes, it appears to be better documented from oceans and sea expanses.
King's Highway 61, commonly referred to as Highway 61 and historically known as the Scott Highway, is a provincially maintained highway in the Canadian province of Ontario. The 61-kilometre (38 mi) route connects the Pigeon River Bridge, where it crosses into the United States and becomes Minnesota State Highway 61, with a junction at Highway 11, Highway 17 and the Harbour Expressway in Thunder Bay. The highway forms part of the Lake Superior Circle Tour.
An ice road or ice bridge is a human-made structure that runs on a frozen water surface. Ice roads are typically part of a winter road, but they can also be simple stand-alone structures, connecting two shorelines. Ice roads may be planned, built and maintained so as to remain safe and effective, and a number of guidelines have been published with information in these regards. An ice road may be constructed year after year, for instance to service community needs during the winter. It could also be for a single year or two, so as to supply particular operations, such as a hydroelectric project or offshore drill sites.
Aufeis is a sheet-like mass of layered ice that forms from successive flows of ground or river water during freezing temperatures. This form of ice is also called overflow, icings, or the Russian term, naled. The term "Aufeis" was first used in 1859 by Alexander von Middendorff following his observations of the phenomenon in northern Siberia.
King's Highway 7A, commonly referred to as Highway 7A, is a provincially maintained highway in the Canadian province of Ontario that serves as a bypass of Highway 7. The highway begins in the community of Manchester, where Highway 7 is concurrent with Highway 12, and travels east through Port Perry, Nestleton Station, Bethany and Cavan, ending at Highway 115 southwest of Peterborough. From there, Highway 7 can be reached via Highway 115 northbound. Near its midpoint the route is concurrent with Highway 35 for 1.5 kilometres (0.93 mi).
The Yellowknife Highway, officially Northwest Territories Highway 3 and also known as the Great Slave Highway, is a highway connecting Yellowknife, Northwest Territories, to the Mackenzie Highway, from a junction 188 km (117 mi) north of the Alberta border. First completed in 1960 as a gravel and dirt road, the highway is now paved and realigned after years of work concluded in 2006. Access to Yellowknife prior to the opening of the Yellowknife Highway was possible only by airplane, winter road, or boat across Great Slave Lake.
Cellular confinement systems (CCS)—also known as geocells—are widely used in construction for erosion control, soil stabilization on flat ground and steep slopes, channel protection, and structural reinforcement for load support and earth retention. Typical cellular confinement systems are geosynthetics made with ultrasonically welded high-density polyethylene (HDPE) strips or novel polymeric alloy (NPA)—and expanded on-site to form a honeycomb-like structure—and filled with sand, soil, rock, gravel or concrete.
The Russian Maritime Register of Shipping (RMRS) maintains a ship register of the Russian Federation, based in Saint Petersburg, and is a marine classification society. Its activities aim to enhance safety of navigation, safety of life at sea, security of ships, safe carriage of cargo, environmental safety of ships, prevention of pollution from ships, and performance of authorisations issued by maritime administrations and customers.
Pressure grouting or jet grouting involves injecting a grout material into otherwise inaccessible but interconnected pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting.
Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure, the more people get about by bicycle.
Svein Olafur Sigfusson was a Canadian athlete and entrepreneur. He won a bronze medal in the discus throw at the 1950 British Empire Games and was Canadian champion for the hammer throw.
Offshore geotechnical engineering is a sub-field of geotechnical engineering. It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. Oil platforms, artificial islands and submarine pipelines are examples of such structures. The seabed has to be able to withstand the weight of these structures and the applied loads. Geohazards must also be taken into account. The need for offshore developments stems from a gradual depletion of hydrocarbon reserves onshore or near the coastlines, as new fields are being developed at greater distances offshore and in deeper water, with a corresponding adaptation of the offshore site investigations. Today, there are more than 7,000 offshore platforms operating at a water depth up to and exceeding 2000 m. A typical field development extends over tens of square kilometers, and may comprise several fixed structures, infield flowlines with an export pipeline either to the shoreline or connected to a regional trunkline.
Ian Jordaan is a Canadian civil engineer who has made contributions to the design of offshore structures for harsh, cold environments. He is a professor emeritus and university research professor in the Faculty of Engineering and Applied Science at Memorial University of Newfoundland.
A snow road is a type of winter road, which is a road that is used or trafficable only in the winter. Snow roads make up some or all of the on-land segments of a winter road. The snow is either compacted in place or, when there is not enough of it, is hauled from elsewhere, then compacted. The snow may be processed, for instance, by agitation to reduce the size of the particles before compaction. Additional snow is also used to help protect the vegetation and as a means of improving trafficability. This snow, sometimes referred to as 'snow pavement', can be compacted to various level, depending on requirements and available equipment – a higher compaction will accommodate heavier vehicles and higher tire pressures.

The Neoloy Geocell is a Cellular Confinement System (geocell) developed and manufactured by PRS Geo-Technologies Ltd. Geocells are extruded in ultrasonically welded strips. The folded strips are opened on-site to form a 3D honeycomb matrix, which is then filled with granular material. The 3D confinement system is used to stabilize soft subgrade soil and reinforce the subbase and base layers in flexible pavements. Cellular confinement is also used for soil protection and erosion control for slopes, including channels, retention walls, reservoirs and landfills.
