AS-BUILT SURFACE 3D MODEL SERVICES

In the land survey industry, many companies are under heavy pressure to both ensure project progress and maintain the quality of drawings to international standards. Company owners and project managers often bear too much of the workload themselves, while recruiting highly skilled engineers is increasingly difficult and the operating costs of an in-house team are constantly rising. Project volumes often fluctuate erratically, sometimes too low, sometimes surging, which can easily lead to an overloaded internal workforce. Many companies are concerned about outsourcing, fearing difficulty in controlling costs, quality, and progress, while the need to complete as-built documentation accurately, quickly, and in compliance with technical standards is always high.

As-Built 3D surface model services emerged as a comprehensive solution, helping companies obtain an accurate 3D surface model reflecting the current state of construction using advanced data scanning technology. The service thoroughly addresses issues related to personnel, costs, and deadlines, while ensuring drawing quality meets standards, supporting companies in enhancing their reputation and operational efficiency.

Challenges that should make companies consider outsourcing as-built surface 3D model services

In the land survey field, delivering accurate, complete, and internationally standardized as-built documentation is a mandatory requirement to ensure project quality and company reputation. However, producing high-quality as-built drawings is not simple. Many companies face difficulties with personnel, operating costs, and the ability to meet deadlines, especially when project volumes fluctuate erratically.

For small and medium-sized land survey companies, the personnel issue is always a major obstacle. Company owners often have to directly participate in technical work because they cannot recruit highly specialized engineers. Fluctuating project volumes make it difficult for them to maintain a stable in-house team. When the number of projects surges, they can easily become overloaded, but when work decreases, personnel and operating costs become a burden.

Larger companies have more resources but must simultaneously execute multiple important projects with strict requirements for standards and deadlines. Even a small error in the as-built documentation can lead to delays, cost overruns, and directly impact their reputation with investors. In parallel, the excessive workload prevents in-house teams from focusing on the company’s core tasks. At this point, every task seems to require immediate attention, leading to feelings of being overwhelmed. They need an As-Built surface 3D model services provider with proven capabilities, a clear track record, and professional workflows to support tasks while ensuring quality and progress for multiple projects simultaneously.

For sole company owners or micro-companies, there’s a different challenge: expanding personnel isn’t a viable option due to excessive costs and management time. However, when projects suddenly arise, finding experienced engineers to immediately deploy is almost impossible. They need a flexible solution that can begin work immediately when needed without a complicated process.

Conversely, there’s a special group of companies that have outsourced services many times but have never been truly satisfied. They understand the benefits of outsourcing but have been repeatedly disappointed by poor drawing quality, numerous errors, slow progress, or cumbersome and unprofessional communication processes. These negative experiences make them hesitant to seek a new provider, fearing that the results of the collaboration will still not meet expectations.

As-Built surface 3D model services offer a comprehensive solution to help companies overcome all the above challenges. The service uses 3D laser scanning technology to scan the current state of construction, collecting millions of precise measurement points and processing them into a detailed point cloud. From there, the data is converted into a CAD or BIM-compliant 3D surface model, faithfully reflecting the actual state of the construction after completion. This model helps companies easily deliver standard as-built documentation, cross-reference with the initial design, detect discrepancies, and effectively serve renovation design, quality control, and asset management.

Outsourced As-Built surface 3D model services provide small companies with flexibility and cost savings, offer large companies a reliable resource for deploying multiple projects simultaneously, and help sole company owners initiate work immediately when needed without the burden of recruitment. Especially for companies that have been disappointed by outsourcing in the past, this service makes a difference with accurate drawing quality, guaranteed progress, and clear workflows, helping them regain confidence in outsourcing.

Optimized value for companies choosing as-built surface 3D model services

After recognizing the difficulties and risks of in-house implementation or partnering with unprofessional providers, companies need a truly effective and reliable solution. As-Built surface 3D model services not only help solve personnel and cost issues but also bring practical value, ensuring the quality and progress of every project in the land survey sector.

The first value this service offers is superior accuracy in as-built documentation. By applying 3D laser scanning technology, the entire as-built condition of the structure is scanned and collected as millions of measurement points with extremely small errors. This data is processed into a detailed point cloud, then converted into a CAD or BIM-compliant 3D surface model. As a result, the as-built drawings accurately reflect every real-world detail, making it easy for companies to cross-reference with the initial design and minimize errors during handover.

The second value lies in the ability to shorten timelines and optimize project schedules. With a professional workflow, the provider of As-Built surface 3D model services can process large volumes of data in a short time, and is ready to accelerate when a project requires urgent attention. This helps companies not only meet handover deadlines but also maintain stable cash flow, avoiding losses due to delays or unexpected cost overruns.

Another significant benefit is the ability to reduce operating costs. Instead of maintaining an in-house team of engineers with high fixed costs, companies only pay for the service when needed. Outsourcing eliminates recruitment, training, benefits, and infrastructure costs, while still ensuring that projects are executed by experienced drafting teams using the latest technology.

For large companies, this service provides flexibility in resources and deployment scale. When multiple projects are running simultaneously, they can still ensure progress and quality thanks to a reliable partner. For small companies, the benefit lies in being able to start a project immediately without worrying about recruiting or training personnel. Brokerage companies also benefit from partnering with a professional provider, helping them maintain their reputation with end-clients and avoid the risk of losing contracts.

Furthermore, As-Built surface 3D model services also bring long-term value. The as-built model not only serves as as-built documentation but also becomes an important database for renovation design, construction quality control, and asset management throughout the lifespan of the structure. Having a CAD or BIM-compliant 3D model at hand helps companies easily coordinate with relevant parties, minimize design conflicts, and improve operational efficiency later on.

Choosing to outsource As-Built surface 3D model services is not just a situational decision but a smart strategy for companies to focus on their core value. Thanks to this service, they optimize costs, ensure quality and progress, and increase their competitiveness in an increasingly fierce market. With clear processes, high technical capabilities, and quick responsiveness, this service is a reliable solution for every company in the land survey industry.

How does Aidedo provide outsourced as-built surface 3D model services?

What is an As-built 3D surface model?

An As-built 3D surface model is a 3D model of the ground surface, created using real data collected from the construction site during or after the work is completed. It combines this field data with the original design plans to show the actual condition of the site. The model includes features like elevation, slope, and terrain, and helps compare what was built with what was originally designed.

Step by step complete an As-built 3D surface model

Step 1: Receive input data from client

The initial stage involves collecting all available reference materials provided by the client, including:

• CAD files (e.g., DWG/DXF formats for existing linework, contours, or survey data)
• DGN files (commonly used in projects involving MicroStation or Bentley-based workflows)
• PDF documents (such as grading plans, construction drawings, or redline markups)

These files serve as the foundation for verifying control points, site   boundaries, and any relevant surface or design features that will guide the creation of the as-built 3D surface model.

Step 2: Review input data thoroughly and clarify with client before project

All incoming data must be reviewed in detail to identify any inconsistencies, omissions, or unclear elements. Open communication with the client is essential to ensure that the model is built on accurate and agreed-upon information.

Example: Report and discuss any discrepancies found between provided documents, such as inconsistencies between detail drawings and plan views. These differences may impact elevation data, surface features, or boundary interpretations, and should be reviewed and resolved in consultation with the client before proceeding.

Step 3: Build the 3D surface model based on approved design plans

At this stage, the goal is to digitally reconstruct the project’s surface model using the design data provided by the client.

File Preparation: Use MicroStation to convert DGN files to DWG format if necessary, or use Carlson Civil to directly open and process proprietary formats such as .pro, .cl, .sec, .tin, etc.

Surface Modeling in Civil 3D: Utilize the surface modeling tools in Autodesk Civil 3D to recreate the designed surface geometry based on the approved plans.

• Roadway Surface Creation: Build roadway surfaces based on approved road profiles and cross-sections, ensuring elevation and slope accuracy per the final design plans.
• Driveways, Curbs, and Handicap Ramps: Model these features using the construction detail sheets, accurately reflecting the transitions, slopes, and elevations specified.
• Sidewalks and Walls: Create 3D representations of sidewalks and retaining walls according to both the design details and approved plans.
• Swales and Ponds: Remodel swales, detention/retention ponds, and other drainage features with precision, matching the smallest grading annotations shown on the grading plan sheets.
• Building pads and feature lines: Apply Feature Line tools in Civil 3D to define pad elevations, slopes, and breaklines precisely as indicated on the grading plans. This ensures accurate modeling of finished floor elevations, slopes, and drainage compliance.

The focus in this step is not only on replicating the design but also ensuring that every modeled surface reflects engineering intent and constructability standards.

The surface style should follow the standard display conventions (e.g., 1’ and 5’ contours) and be assigned to the correct coordinate system and vertical datum as per project requirements.

Step 4: Adjust the surface based on As-Built survey data provided by the client

During construction, the client may collect actual field data or implement design changes. This field data may be collected using various methods such as GNSS (GPS), total station surveys, UAV (drone) photogrammetry, or LiDAR scanning. All data must be properly georeferenced to the project coordinate system and validated before integration.

Once this updated information is received, the surface model must be revised accordingly to reflect real-world conditions.

This process ensures that the 3D surface model accurately represents the as-built site, incorporating any deviations from the original design due to field conditions, construction modifications, or engineering adjustments.

Step 5: Final review and project submission to client

• First, double-check the surface to make sure it matches the latest data provided by the client.
• Then, export the surface to XML format and open it in Carlson Civil to review it one more time. This helps confirm the surface looks correct in both Civil 3D and Carlson.
• Finally, prepare and send the following files to the client:

XML and TIN files for the surface

DWG/ DGN file with all linework placed on clearly named layers

All linework should be 3D polylines so the client can use them easily in their own software

Step 6: Ongoing updates during construction until final As-built 3D surface model is complete

The project continues to follow the steps above from the pre-construction phase through the entire construction process. The surface model will be updated regularly as new field data becomes available, ensuring it always reflects the latest site conditions. Once construction is complete, a final as-built 3D surface model will be delivered, showing the overall finished condition of the site.
