Future of 3D Technology in Roadwork Construction

3D technology is a new and powerful tool that can have a big impact on the construction of roads. When we use 3D models in highway projects, it can make the work more efficient, benefiting both the construction workers and the public. Let’s break down what 3D technology is, how it’s used in road construction, and how it can benefit the industry.

What is 3D Technology in Road Construction?

Construction teams can use 3D technology as a digital tool to plan and carry out roadway projects. Instead of using traditional two-dimensional paper plans, 3D technology offers a faster and more cost-effective way to build, maintain, survey, and repair highways.

3D models created with this technology result from a thorough assessment, design, and coordination process. They provide a computerized representation that accurately shows the existing site conditions and the designer’s intent. Construction workers can use these 3D models to deliver road construction projects faster and with better accuracy compared to traditional 2D tools.

How 3D Technology is Used

The process of creating a 3D model starts with an aerial scan of the project site. Engineers use pilotless aircraft, like drones, to survey the site. The collected data is then transmitted to a scanning station, where designers use it to create a 3D representation of the construction site.

A complete 3D model includes the initial survey data along with suggested vertical and horizontal alignments, features, and structures for the future site.

Applications in Highway Construction

Whether constructing new roads or updating existing ones, 3D technology can enhance the safety, precision, and efficiency of the process. It’s employed in automated machine control, project management, and quality assurance.

For example, 3D laser scanning allows construction workers to scan and record vital information about the road. This data helps in developing an accurate plan, prioritizing problematic areas, and speeding up overall project completion while reducing traffic issues.

3D technology also facilitates the movement and measurement of asphalt. Instead of traditional methods, where milling machines were used for concrete removal, a 3D scanner helps in digitally detecting the amount of asphalt to be removed. This precise measurement accelerates project completion.

Automated Machine Control

GPS machine control eliminates the need for extensive staking and provides more accurate results. It can be applied to various roadwork construction equipment, such as grading equipment, excavators, compaction equipment, milling, and paving equipment.

Scheduling, Cost Estimating, and Project Management

3D-engineered models aid civil contractors in cost estimating, scheduling, and project management. It streamlines the project and provides value to both the contractor and the project owner. It includes earthwork quantity estimation and facilities management.

Quality Assurance and Post-Construction

3D technology enhances the quality assurance process during roadwork construction. Inspectors can use handheld GPS devices to spot-check horizontal offsets and elevations, ensuring correct grading. This reduces rework and enhances post-construction quality.

How 3D Technology Benefits Roadway Construction

Using 3D technology in roadwork construction offers numerous benefits:

  1. Faster Project Completion: Guidance from 3D-engineered model data enables GPS-enabled machinery to operate efficiently, producing accurate grades on the first pass. This reduces waste, economizes resources, and speeds up project completion.
  2. Better Cost Predictability: A 3D-engineered model allows clients and contractors to see all project elements, facilitating better decision-making. It helps in integrating costs, building accurate budgets, and reducing cost overruns.
  3. Less Asphalt Wastage: With precise milling depth control, operators can adjust the depth of asphalt removal in real time, reducing waste. This optimizes work, makes it more precise, and saves both time and money.
  4. Reduced Human Error: 3D-engineered modeling significantly reduces errors by providing unrivaled precision and accuracy. Detecting mistakes during the design phase is more cost-effective than fixing them on-site.
  5. Higher Transparency for Stakeholders: 3D-engineered models allow contractors and stakeholders to walk through projects before any concrete is poured. Virtual reality (VR) or augmented reality (AR) can be used to provide a clear idea of the project’s outcome.
  6. Lower Overall Cost: Despite higher upfront costs, the investment in 3D technology can save money throughout the project. It provides more precise results, reducing the need for changes and saving time and money.
  7. Enhanced Project Safety: Automation of tasks like staking and stringing lines, combined with technologies like drones, reduces safety hazards for surveyors. It provides a risk-free way to survey a project site.
  8. Real-Time Control and Monitoring: Intelligent technology like 3D models and GPS machine control enables real-time control and monitoring of movement and location, enhancing efficiency.
