Boundary surveys are a product of the thoughtful and experienced analysis of existing record information and survey observations. The review of record documentation is an essential element in the development of a boundary survey and is mandated by the Technical and Procedural Standards of most states.
To facilitate topographic, location, and feature surveys, we utilize a robotic Leica MS 50 Multistation. This instrumentation utilizes remote control machine guidance which facilitates one-man operation for topographic and location surveying, construction site data collection and construction stakeout, and mass-point data collection projects.
Global Positioning System (GPS) technology is a space-based radio-navigation system consisting of a constellation of satellites and ground stations used for monitoring and control. Between 24-32 GPS satellites orbit the Earth at an altitude of approximately 11,000 miles providing users with accurate information on position, velocity, and time anywhere in the world and in all weather conditions (FAA).

Al is very professional and responsive. Communication is great and you can be sure that you will have a job well done that you can rely on. He had to use a marker far from our lot to ultimately establish our boundaries. Glad he's great with geometry!

Al was great to work with. Very experienced and knowledgeable. After completing the work he took the time to walk the site and was able to review some potential zoning issues that might arise from some wet lands and set back requirements related to the wet lands. I will be using him again when it's time to provide the town with my site plan.

I had concerns that my neighbor was encroaching on my property. I reached out to Al to ask if he could conduct a property survey. Throughout the process, Al and his wife Linda were simply outstanding and I could not be more grateful for their professional expertise and services. They adhered to the timeline provided for initiation of the survey. Despite having a plat map that is difficult to interpret, Al and Linda completed the survey ahead of schedule.

After the survey was completed, it was apparent that my neighbor had indeed encroached on my property. I asked Al if he knew of any civil attorneys familiar with property issues and he was able to provide suggestions. There are loads of surveyors out there and it can be daunting trying to figure out who to choose, especially if the stakes are high. Al and Linda were easy to work with, have integrity, impeccable attention to detail, excellent communication skills, and are accommodating to requests (for example, extra boundary pins in addition to the typical four boundary pins placed at the corners of the property). I wouldn't hesitate to reach out to Al and Linda again should the need arise in the future.

Al DiOrio was consistent throughout the process. The work performed included a full property survey with several aerial images brought into the survey to present a good existing conditions plan. The work was performed on time with continuous communication for minor weather-related delays. Good job and great product.

Al has been very helpful and responsive as we prepare to start building our home. Very knowledgeable about the area and the work necessary for the next steps. I would return to Al for any future surveying needs.

Al DiOrio is an experienced surveyor, and Westerly Land Trust has been very pleased with his professionalism, quick response time, and high-quality finished products. Al gave our organization a timeline and budget for our survey --and he was able to come in under deadline and under or at proposed budget. Very satisfied!

We were looking to have our property surveyed in order to find the border between our land and a piece of property being sold that abuts us. Al came highly recommended from another surveyor that we know but is not in our local area. Everything we asked for was done exactly the way we wanted and we now have peace of mind knowing where our boundaries are which he clearly marked.

Anyone looking for a surveyor I highly recommend Al DiOrio - he's professional, has a great two way line of communication keeping you updated on the process and his progress. Lastly he is very reasonable and fair in terms of pricing.

We called Al to survey our property to get accurate markings for the Boundary lines. We were selling a piece of land and needed an accurate account. Al was responsive to all our questions and needs which made the whole process less stressful and understandable. I would recommend Al for all of your surveying needs. He is professional, friendly, knowledgeable and responsive to your needs.

I have worked with Al DiOrio since 2007. Initially I had a survey done as I was concerned with an encroachment on my property. I called on Al years later to go before our Zoning Board for variance on what was the first stage of a renovation on my home. He addressed all seamlessly and supported me through a first time experience with comfort. Recently asked Al to update my Site Plan to complete the final stage of the above renovation.

All three requests were done smoothly and in a timely fashion. I greatly appreciate Al's skills as a surveyor, how organized, focused, efficient and professional he is across the board. He's been a pleasure to work with and I highly recommend him. Paula Ruisi

It was a long process from overgrown site to finished product, see attached photos. Al was very helpful getting us through the requirements to locate the house and the OWTS system to meet state and local codes. he was courteous, professional and timely.
