Surveying

Boundary Surveys

When you need to know where your property lines are, API Survey will make sure they are accurately located and marked. Protect yourself and don’t build until you are confident the limits are established and properly defined.

Control Surveying

We can establish accurate horizontal and vertical project control utilizing the newest equipment models available. GPS, robotic total stations and digital levels are part of our surveying toolbox.

Route Surveys

We have surveyed over 350 miles of transmission line routes in the past 5 years. Route surveying has been a major slice of our business model and we have extensive experience in establishing route alignments and individual parcels along the route. We also perform route surveying for new or existing highways and interstate projects.

Topographical Surveys

If you need to know the slope on your land or the features located on it, we can perform a topographic survey and prepare a map displaying all the features of the property. Our work is performed in accordance with the Illinois Minimum Standards for Topographical Surveys. Generally a topographic survey is performed so a building site design can rely on it for a new development.

Aerial Drone Surveying

API utilizes quadcopter drones to collect imagery over rock quarries and stock piles and utilizes the data to calculate the stock pile volumes and amount of material in the piles. We can use our drone to perform topographic ground elevation surveys or to just acquire a nice photograph of the family farm.

Construction Layout

When you want to build something, it is important to build it in the correct location and in accordance with the design plans. API has been performing construction layout and staking services since 1992 and we take pride in meeting our client’s needs and keeping the construction project on schedule. From power plants and major bridge interstate projects to small office buildings or a simple bank parking lot, no project is too big or too small for API.

Hydraulic Surveys

Find out how the bottom of the river or lake is contoured and determine the depth of the water and how the river or lake will affect the quality of living adjacent to it. API can survey the bottom of the lake and contour of the water’s edge and determine a volume of water in the lake at various water surface elevations.

ALTA/NSPS Land Title Survey

When the project requires a detailed ALTA/NSPS Land Title Survey, API is the company to call. Our licensed surveying staff has performed several ALTA/NSPS Land Title Surveys in accordance with the standard specifications for this type of survey.

Engineering

Commercial & Industrial Site Designs
