Building on Accuracy - A Case Study in Boundary Surveying and Improvement Detection

Overview

The case study is about boundary surveying for a property, intending to locate the site of any renovations, including a shed. Finding the shed's location was essential to making sure it didn't cross the property line of the neighboring parcel. A thorough boundary survey was carried out in compliance with the client's requirements and local laws. This survey was conducted using on-site surveys and deed records. Its goal was to verify the shed's exact position and highlight all noteworthy upgrades on the owner's land.

Scope of Work

Here, we conducted a detailed boundary survey of the land mentioned in the Deed/Title commitment. The details of the land were explained using the Metes and Bounds method in the Deed. To conduct the survey, the documents used were deed legals of adjacent land to verify its boundaries, a detailed and accurate field survey sketch, a .txt or .csv file of point coordinates retrieved from the land survey, and real-time images of the owner’s property for a better understanding of the actual condition. The team utilized CAD drafting software to ensure accurate and efficient results throughout the drafting process.

Challenges

The property's primary problem was the difference between the deed's legal border and the boundary as established by the survey. Very few reference sites were discovered to be able to precisely determine the boundaries of the area during the first survey phase. A major obstacle was created by this 3-foot difference in the border.

Solutions

We found errors in the property's legal description after examining the legal descriptions of the relevant property and the nearby parcels. There was a mistake in the legal description as evidenced by the wrong bearings and distances given. We determined the precise boundaries of the property by correcting this inaccuracy in compliance with the adjacent deed.

Later, as the lot and surrounding deeds were being drafted, we saw that there weren't enough restrictions in the area, which made it difficult for us to perform a boundary resolution. To support our claim of rotation, we were encouraged to ask the client for further controls. We rectified the border issues after obtaining the needed data and carrying out additional studies.

To produce an accurate Boundary survey, we investigated several rotation choices using the identified monumentation, took into account the location of modifications, and referred to recent photos. This survey included dimension ties on every side of the land and included information on all improvements, including fences and buildings. Furthermore, from the Title Commitment SBii Exceptions, easements affecting the subject land were located.

To guarantee the integrity and correctness of the survey, a thorough quality check was carried out after the drafting process. To ensure the survey was accurate and free of errors, every detail was carefully examined against a checklist.

Result

The survey revealed that the shed continued one foot onto the adjacent parcel beyond the property border; this was indicated in red on the drawing to indicate the distance to the property line. Upon submission, the client was quickly informed of this disparity.

As a result, the final survey verified that the shed did, in fact, slightly intrude into the neighboring property, which was consistent with the results of the field survey and the documented legal description. For the client's reference, the survey displayed inaccuracy in the legal description.

Surveying Solutions - Ensuring Accurate Fence Placement and Boundaries to the Property

Overview

The old fence was in poor condition, so one of the neighbors rebuilt it entirely. A fresh boundary study was thus required to determine if the rebuilt fence was properly placed and did not intrude into the neighboring land. To comply with local laws and client requests, we created a comprehensive boundary survey that considered any developments on the owner's land and was based on the Title/Deed documents and the field survey.

Scope of Work

As part of our work, we carried out an exhaustive boundary survey of the particular piece of property that was described in the legal documents that the Deed or Title deed provided. The paperwork consisted of a Lot & Block deed, which provided the exact information on the property's borders. We needed a few essential inputs to conduct this survey properly. To comprehend the design of the land, we had to have access to the Subdivision Plat referenced in the Deed.

A precise field survey drawing was also necessary to record measurements and other facts from the location. In this we utilized a point coordinate file, typically formatted as .txt or .csv, to meticulously map the property's distinctive features, gathered through our comprehensive field surveying process. Lastly, images of the property are a priceless resource that helped us visualize the current state and provided guidance during the writing process. We guaranteed the precision and dependability of the border survey by employing this extensive range of inputs. To complete this process the team decided to use CAD Designing Software to ensure accuracy and efficiency in the result.

Challenges

Drafting the lot or parcel from the previous subdivision plat, which lacked important angle and bearing information, was our main issue. Our surveying procedure was hampered by this antiquated paper, which needed to be repaired with creative thinking and specialized knowledge. Our team overcame these difficulties and produced accurate survey findings by navigating the drafting process well.

Solution

We established an optimal method for drawing the lot after evaluating the data that was supplied and the controls that our survey team had found. We chose to use the field monuments that our team had found and cross-reference them with control sites that were close by or adjacent, including sites of Curvature (PCs), Points of Intersection (PIs), and Permanent Reference Monuments (PRMs). The correctness and dependability of this technique were verified by what are known as Plat Ties.

After assessing several possibilities based on the monumentation and taking into account where improvements are located, we used up-to-date photos to provide an accurate Boundary survey. This survey precisely positioned all constructions and other property upgrades using dimension ties on all sides. To be more precise, we made sure the fence was anchored to the boundary line so that its location could be easily determined. To ensure compliance with building laws, we also displayed County Setbacks and easements as specified by the Subdivision Plat. To improve overall accuracy, nearby controls were also incorporated into the survey to confirm orientation and property location.

Additionally, the client's template was painstakingly filled up with complete property information, owner data, and the address of the property, guaranteeing clarity and accuracy.

Using our checklist, a comprehensive quality check was carried out after the writing phase. Every detail was examined to ensure that there were no inconsistencies and that the survey result was accurate and error-free.

Results

Our study therefore validated that the new fence's location precisely matched the field data that was gathered. We firmly attached the fence to the property, demonstrating its closeness to the border within the subject property, to accurately capture this alignment in our survey data. For the sake of future reference and property administration, this guaranteed that the fence's placement was accurately described.

Using LiDAR Mapping to Unlock Ski Area Potential

Overview

The client needed to develop a Skiing area over mountain terrain. Before developing the Skiing area, the client wanted us to study the terrain and area. The client had data ready using the total station and drone. Using this information, we had to create land contours and match the two data sets; a Digital Terrain Model (DTM) file was to be made, and data processing was needed. This project had many challenges, including the initial data provided for processing, but, using AutoCAD and skilled manual analysis, the final DTM file was provided to the client.

Challenges

The main challenge was the inaccurate drone data because the instructions given to the drone before capturing were incorrect. This made the processing of the data challenging. Another challenge that we encountered was that, after the completion of data processing, the client had more changes. These changes were required after the client revisited the site.

Solution

1. We reprocessed the data 2-3 times before the actual data processing to correct the incorrect drone data.
2. Then, using AutoCAD, millions of LiDAR data points were sub-sampled and made into thousands of cloud data points.
3. After this, we created contour lines to show waterfalls, elevations, and other landscape features.
4. We then shared the draft with the client. After the client had revisited the site, they required certain changes.
5. After understanding the changes, a final Digital Terrain Model (DTM) file was created and given to the client.

Results

The final draft of the processed LiDAR data was provided to the client in a Digital Terrain Model (DTM) file.

A Closer Look at 3D Road Mapping

Overview

The client required us to study a 5-km-long road and provide accurate 3D line work. Using the LiDAR drone-captured images and data, the existing condition of the road was to be studied. The drone-captured data was converted into GeoTIF files for a clearer study. Some challenges were encountered due to the data size, but using AutoCAD and different software, a clear 3D line work and a Digital Terrain Model (DTM) file were provided to the client.

Challenges

The main challenge was the data size of the 5 km long road. Data processing of this data was time-consuming and difficult. Another challenge was point snapping and drafting the data in 3D. This data was difficult to be marked and analyzed in 3D.

Solution

The large image dataset was divided into small sections to be processed and analyzed. To work on the image in AutoCAD, we made 20 sections. Now, for point snapping and drafting of the data in 3D different views and angles of the area were used. To view and analyze the image in various views, ReCAP was used. After this, the file was drafted in an asymmetric view. To get better 3D line work, cross-sections were made every 50m to show elevations and descriptions of each point.

After creating the line work, contours were made. Using these contours and line work, utilities on the road, manholes, strippings, center lines, markings, curves, gutters, sidewalks, edges of pavements, and other details were captured and created. Finally, after the 3D line work, elevation marking, and data processing were completed, 3D line work, a DTM file, and a point file were provided to the client.

Results

Three files were prepared and sent to the client: a point file, a DTM file, and accurate 3D line work.

Surveying Cracks in Bridges - Aerial Inspection

Overview

The client required a survey of an old bridge whose images were captured using a drone. The client required the identification of cracks on the bridge with their exact location, size, width, and other details. Also, the development scope of the bridge was required with the crack report. Using PTGui and FUJI, we identified the cracks and their details, and the final report was submitted to the client.

Challenges

The main challenge we faced was with aligning the images. The areas photographed were the inside portions of the Girder of the bridge structure. As all internal parts were similar in shape, it was necessary to work in a manner that easily identified portions. For this, all internal structures were shot with identifiers that helped to identify each section of Girder. The Girders were in odd shape having an oval shape at the sides and flat at the bottom and top. Since every shot showed the same form, it proved difficult to determine the precise size.

Another challenge we faced was the analysis of the photos. Because these photos were taken from different angles, identifying the exact location of the crack using 400 images per section was a task. Another challenge we faced was the arrangement of various photos of each section and getting one picture with the exact location of the crack.

Solution

To analyze the photos, PTGui was used to get the exact location of the cracks. PTGui helped us stitch different images from three angles-left, right, and center-and get the location. Utilizing state-of-the-art surveying instruments, world-class photographic software such as PTGui – developed by the New House Internet Services BV, Adobe Photoshop, add-on tool FUJI by Fujifilm, and Computer-Aided Design (CAD) software, our team ensured accuracy and efficiency in the analyzing process and Microsoft Excel to create a report on each of the cracks.

Certain identifiers were used to get one photo of the section. This was done to identify cracks in each section with 400 images each. These photos were analyzed in FUJI to get the width, length, size, and other details of the crack. We took the output from FUJI to AutoCAD for manually analyzing details. This data was then set to our standards. Finally, the data was exported to the Excel sheet, where the location of each crack in XYZ coordinates, width, size, and other required details were mentioned.

Results

The final result submitted to the client was an Excel sheet with the exact location of the crack and the corresponding images.
