Frequently Asked Questions
Got Questions? We’ve Got Answers
What types of land surveying services do you offer?
We provide a wide range of services including boundary and property surveys, topographic mapping, construction staking, land subdivision, as-built surveys, and GNSS/GPS-based data collection. Our services are tailored to meet the needs of developers, engineers, architects, and property owners.
How long does a land survey usually take?
The time required depends on the size and complexity of the property. A simple residential boundary survey can take 1–3 days, while larger or more technical surveys may take a week or more. We always strive to deliver accurate results within a reasonable timeframe.
Why is a land survey important before starting a construction project?
A land survey ensures that property boundaries are clearly defined and helps prevent legal disputes or costly construction errors. It provides accurate data for site planning, design, and regulatory compliance, ensuring your project begins on solid ground.
What equipment and technology do you use?
We use modern GNSS (Global Navigation Satellite System) receivers, total stations, drones for aerial mapping, and advanced CAD/GIS software to deliver precise and reliable surveying results. Our team stays up to date with the latest surveying innovations.
Do I need a survey if my land was surveyed in the past?
Yes, especially if the previous survey is outdated or if there have been changes to the property (e.g., new construction, land division). Local authorities or lenders may also require an updated survey for permitting, development, or legal purposes.
