WHO WE ARE
WE HAVE 25 YEARS OF COMBINED EXPERIENCE IN LAND SURVEYING, LAYOUT FOR GENERAL CONTRACTORS AND REALITY CAPTURE.
We have 25 years of combined experience in land surveying, layout for General Contractors and reality capture. With established roots at one of the oldest land survey firms in our area, we understand the value of survey control. At JTM Construction, we combine proven survey practices with the latest tech available to provide reliable information to our field crews and project teams. With Reality Capture Services (RCS), we aim to fill a void in the market and provide that same service to you.
JTM IS UNIQUE, AS WE OFFER REALITY CAPTURE SERVICES AS A SEPARATE SERVICE.
DECREASED RISKS
Understanding your building spatially is critical before design starts. Documenting existing conditions allows you to intelligently configure your space. An accurate model of the existing space dramatically decreases your risk of schedule impact due to unforeseen conditions or lack of information when construction starts. From there, the sky is the limit for what you can do with your digital assets.
COST EFFECTIVE
Reality Capture services reduce costly rework and improve efficiency by providing precise, real-time data. With 3D scanning and digital modeling, teams can accurately document conditions, detect conflicts early, and streamline coordination—minimizing delays, material waste, and labor costs. At JTM, we leverage this technology to deliver smarter, more efficient builds.
MAXIMIZING EFFICIENCY: 3D MODELS
Point clouds can be large and challenging to use in Revit, but our streamlined Scan-to-BIM workflows transform complex data into an accurate, high-quality BIM model. This allows you to start your work with confidence, improving design accuracy, coordination, and overall project efficiency while reducing rework and costly delays.
PROOF OF CONCEPT
We have a proven track record of reality capture successes both internally at JTM Construction and externally with some of our earliest RCS clients. We have performed work in the private and public sectors with various scopes that have included residential, commercial and industrial spaces. We provide services for quantity tracking, historical preservation, quality control and coordination, detailed as-built information, scan to BIM services and more.
REALITY CAPTURE SERVICES
We cope with rapid innovation in the construction industry by staying up to date with the most current technology, optimizing our workflows, and curating a range of accessible deliverables. We have a track record of successful projects because we provide digestible and reliable data. Our goal is to make reality capture relevant to the needs of our clients. We provide 4x the amount of data than the average contractor
Scan overlay allows us to place a 2D cad file in a 3D environment. Once placed we are able to see any deviation between reality and plans.
Point clouds are heavy data sets that Revit struggles to handle. JTM’s BIM team is well versed in working with this data and uses software to streamline the creation of BIM models that allow our clients to get straight to work, accelerating the process.
After scanning a space we are then able to see how level the floors are to aid in floor leveling and cost control for adapting a space for future needs.
When a full model isn’t needed we can provide the point cloud as a mesh in an IFC file format to better visualize the data collected and design inside the constraints of a space.

REALITY CAPTURE SERVICES
Many older buildings lack accurate, up-to-date as-builts. With scan-toplan technology, we can quickly provide precise 2D CAD files.
Scanning for BOMA gives you the ability to get what you need now and have data available for any work that might happen in the future.
We can capture an existing space and compare the data to contract documents or models to verify the work in place meets the requirements of the owner or designer.
Laser scanning a space allows us to segment objects and classify them.
Once this is done, we can rearrange the space for maximum efficiency without interrupting the operators of the space.
CASE STUDIES: SCAN TO BIM
WESTLAND HOTEL
CLIENT: Urban Villages
LIDAR SCAN OF EXISTING HISTORIC BUILDING
• Provided accurate location of existing structural elements to ensure constructability.
• Identified that the architectural model was built perfect and the space was imperfect, due to the 100+ year old nature of the building, mitigating costly installation delays.
• Columns were out of square, due to environmental factors such as building settlement, earthquakes, etc. The scans allowed the team to accurately construct in areas where structures deviated from the new architectural drawings.
Once captured we can calculate the volume of any material on site that needs to be removed or added to help with budgeting or estimating the cost of a project.
Our floor analysis has helped projects stay on budget while providing insight into the performance of the decks under construction.
CASE STUDIES: AS-BUILT MAPPING
747 PLANE COORDINATION AT 1200 STEWART
CLIENT: Westbank
LIDAR SCANNING
• The 747 plane was cut into 30+ pieces. The team used the Lidar scan to capture all of the parts for coordination of MEPF that will be installed in the belly of the plane. The plane will be a functional space with an upscale bar for guests.
• Capturing all the plane pieces, aligning them with the model, allowed our team and trade partners to coordinate the field work.
• The client’s model depicted the plane as a whole, so our team had to carefully align the segmented scanned pieces to ensure accurate coordination and installation.
Temperature mapping allows us to compare the as-built conditions of the design intent of the object.
Verticality reports allows us to map the entire hoist way/walls to check plumbness and can be sent out as 3D PDFs.
SCANNING SUITES
JTM Construction’s state-of-the-art scanning suites, powered by advanced reality capture technology, provide significant benefits to owners and architects by delivering highly accurate, detailed 3D data of existing conditions. This technology allows for precise planning and design, reducing costly errors and unforeseen challenges during construction. By offering a clear visualization of the project from the start, JTM enhances collaboration between stakeholders, streamlines decision-making, and ensures alignment with the owner's vision and the architect's intent. With this innovative approach, JTM helps bring projects to life efficiently and with exceptional quality.
