Transportation is the movement of people, animals and goods from one location to another. The various modes of transportation include air, rail, road, water, cable, pipeline and space.

Transport infrastructure includes roads, railways, airways, waterways, canals and pipelines and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations) and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance.

Highway Infrastructure and Motor Carrier encompasses nearly 4 million miles of roadway, almost 600,000 bridges, and some 400 tunnels in 35 states. Vehicles include automobiles, motorcycles, trucks carrying hazardous materials, other commercial freight vehicles, motorcoaches, and school buses.

We at Garden State have worked in every possible mode of transport including air, rail, road, water, cable, pipeline and space. See our long list of services and projects for more detailed project scopes and pictures and deliverables.

Railroads, once a presumed secondary form of transportation, is currently going through a considerable resurgence. The U.S. rail network are made up of more than 160,000 miles of track, 76,000 rail bridges, and 800 tunnels across the nation that are shared by all operators moving freight and passengers. In a heavy urban area like the New York Metro area, the movement of people and commerce relies heavily on this form of transportation and it’s resurgence is vital to this region’s economy. The New York Metro area has many agencies and companies handling their rails including Amtrak, NJ Transit, MTA (NYCTA, Metro North and LIRR), PANYNJ, CSX, Norfolk Southern and SEPTA.

Garden State has years of survey and engineering experience working with these agencies and companies to upgrade their rail infrastructure. From being the designer of record on the Northeast Corridor Platforms for Amtrak to surveying tunnels for the NYCTA on the East Side Access project, Garden State’s knowledge of the rails and stations throughout the region is unique among the rest. View our list of projects where Garden State’s expertise has successfully contributed to the improvement of this growing transportation alternative.

Commercial / Industrial

A commercial building can include office buildings, warehouses, or retail (i.e. convenience stores, “big box” stores, shopping malls, etc.). Commercial property includes office buildings, industrial property, medical centers, hotels, malls, retail stores, farm land, multifamily housing buildings, warehouses, and garages. In many states, residential property containing more than a certain number of units qualifies as commercial property for borrowing and tax purposes.

An important, defining characteristic of industrial space is Clear Height. Clear height is the actual height, to the bottom of the steel girders in the interior of the building. This might be 14‐16 feet for smaller properties, and 40+ feet for larger properties.

We at Garden State have worked on a broad range of commercial buildings from assisted living facilities to shopping malls to industrial-type plants/structures. View our long list of services and projects for more detailed project scopes, pictures and deliverables.

Marine/Water and Waste assets include dam projects, hydropower generation facilities, navigation locks, levees, dikes, hurricane barriers, mine tailings and other industrial waste impoundments, and other similar water retention and water control facilities. This is a vital part of the nation’s infrastructure and provides a wide range of economic, environmental, and social benefits, including hydroelectric power, river navigation, water supply, wildlife habitat, waste management, flood control, and recreation.

There are approximately 160,000 public drinking water systems and more than 16,000 publicly owned wastewater treatment systems in the United States. Approximately 84 percent of the U.S. population receives their potable water from these drinking water systems, and more than 75 percent of the U.S. population has its sanitary sewerage treated by these wastewater systems.

We at Garden State have worked on a broad range of marine/water/waste system projects. See our long list of services and projects for more detailed project scopes and pictures and deliverables.

Office / Residential Hi-Rise

New York City is undergoing a new renaissance of office/residential hi-rise construction. The new and proposed “supertall” buildings which stand over 1,200 feet are just a small segment of this market, which includes luxury condominiums to hotels to office buildings. New York City alone has over 100 skyscrapers which stand over 500 feet tall and more are being developed every day. Hi-rise buildings are not confined to New York City alone, as New Jersey has also jumped into this market in Jersey City, Newark and Fort Lee.

Garden State has been on the front line of this market segment since we were the surveyor for One World Trade Center, currently the tallest building in North America and first “supertall” in over 4 decades. Garden State continues to work on these structures including 4 WTC as well as other hi-rise building throughout the city. View our complete list of services and more detailed project scopes, pictures and deliverables involving the office/residential hi-rise construction industry.

The highway infrastructure encompasses nearly 4 million miles of roadway, almost 600,000 bridges, and some 400 tunnels in 35 states. The health of our nation’s bridges is directly tied to the nation’s ability to compete in a global marketplace. Therefore, it is of growing concern that the bridges and tunnels in our nation’s metropolitan areas, which are an indispensable link for both millions of commuters and freight on a daily basis, are decaying more rapidly than our rural bridges.

New York City is home to over 2,000 bridges and tunnels with several agencies manage this network of crossings, including the New York City Department of Transportation (NYCDOT), Metropolitan Transportation Authority (MTA), Port Authority of New York and New Jersey (PANYNJ), New York State Department of Transportation (NYSDOT) and Amtrak.

Garden State has been actively involved with many of these agencies in various capacities serving as surveyors and engineering support. Adding to this has been our far ranging support throughout New York and New Jersey and other projects in Louisiana and Pennsylvania and on the international front.

The energy infrastructure is divided into three interrelated segments, including: electricity, petroleum, and natural gas. The U.S. electricity segment contains more than 6,413 power plants (this includes 3,273 traditional electric utilities and 1,738 nonutility power producers) with approximately 1,075 gigawatts of installed generation.

Approximately 48 percent of electricity is produced by combusting coal (primarily transported by rail), 20 percent in nuclear power plants, and 22 percent by combusting natural gas. The remaining generation is provided by hydroelectric plants (6 percent), oil (1 percent), and renewable sources (solar, wind, and geothermal) (3 percent).

The heavy reliance on pipelines to distribute products across the nation highlights the interdependencies between the Energy and Transportation Systems Sector. Pipeline Systems consist of vast networks of pipeline that traverse hundreds of thousands of miles throughout the country, carrying nearly all of the nation’s natural gas and about 65 percent of hazardous liquids, as well as various chemicals. These include approximately 2.2 million miles of natural gas distribution pipelines, about 168,900 miles of hazardous liquid pipelines, and more than 109 liquefied natural gas processing and storage facilities.

Garden State has been involved from its inception in the fields of the Alaskan Pipeline, where our original founder was an instrumental leader in providing the surveying services in that distant wilderness to the various construction contractors. His tradition of excellence and perseverance has continued within the legacy of Garden State and its people. We continue the tradition by working on projects involving co-generation plants, wind, solar, and emerging energies.
