Point Cloud to BIM and Efficient Project Management – an Insight

The technology of 3D scanning and converting it into a 3D model has its applications into various fields. It is helpful and used in the Building Industry, Process Industry and Digital Factory, for the purpose of Reverse Engineering, Ship Building, Documentation of accident and forensic scenes, Facility Management, etc. 

In relation with the Building Industry (AEC), scan to BIM is the process by which a Building Information 3D Model (BIM model) is created from scanned point cloud data to accurately represent the ‘As Built’ environment. The laser scan point cloud survey data is collected and registered by certified surveyors and it is this registered point cloud from which the BIM model is produced.

Scan to BIM Still Requires Expert Modelers

It is interesting how an entire 3D space can be scanned into a point could model, replete with intrinsic geometry details. This technology is popularly and very efficiently used to represent the ‘As built’ environment for both new buildings and refurbishment/renovation projects. BIM point cloud technology might sound very costly, but for large scale renovation projects, it is extremely useful and cost effective.

3D MEP Coordination : Streamlined Communication Across Construction Projects

The efforts of AEC firms are always aligned towards increasing process efficiency and reducing design iterations and hence considerably reducing the amount of rework.

The architectural engineering and construction firms are always under pressure to perform to their best potential and deliver projects within the proposed deadlines. Repeated need of iterating and altering design and construction, results in a lot of rework. This has a cascading effect on all aspects of a construction project including productivity, project deadlines and the set budgets.

Why BIM is Boon for Construction?

Building Information Modeling popularly known as BIM is rapidly turning into an improved, recognized, and proven collaboration method in the construction industry.

BIM for construction is used in vast proportions by construction managers, architects and engineering companies. Construction companies are now capitalizing on BIM technologies starting from bidding to post construction process.

How to Improve Cost, Scheduling and Coordination of Building Project

Building information services is a key for architects to help them achieve their design-centric tasks. It also provides various benefits including enhanced BIM coordination, constructability analysis, cost estimation and scheduling of building project.

Gantt chart, used to observe project progress against time constraints, is named after Henry Laurence Gantt, an American mechanical engineer. Though it was a useful process for project planning, it lacked something when it came to visualizing the project timelines. This is where BIM 4D modeling came into picture.

3D Building Model Reconstruction from Point Clouds - Successful Renovation and Refurbishment Project Management

The industry has always focused on BIM adoption and implementation for new built structures. However, new buildings form only a small percentage of the total number of buildings that exist.

So, how does BIM play a role in influencing projects for retrofits and existing buildings of heritage and architectural significance? 

One of the primary requirements of using BIM effectively, for refurbishment, renovation, repair and maintenance projects is – collection of detailed and accurate information about the building. Manually collecting information regarding the architectural, structural and MEP disciplines of a facility can be difficult. Hence, laser survey technology is widely used for this purpose.

Highly sophisticated 3D laser scanners are used to collect data of an existing building in the form of point cloud models.

Challenges of 3D Building Model Reconstruction from Point Clouds 

While information collection using the point cloud technology is easy as compared to manual collection, Surface Reconstruction from Point Clouds requires extensive remodeling and expert intervention. The 3D models obtained from laser scans have to be converted into triangle mesh, polygon mesh or a NURBS surface model.   

However, the point cloud data for complex structures and larger buildings is of enormous file size. In addition to BIM expertise, it is also important to have the required infrastructure and hardware capabilities to accommodate and handle humongous volumes of point cloud data easily.

Scan To BIM Wave Sweeping the Middle East Region 

The Middle East region is experiencing a spurt in BIM adoption for retrofits, renovation and refurbishment projects. Scan to BIM is also increasingly used for accurate documentation of large and complex buildings. Building information modeling adoption will help UAE to become a world leader in building and infrastructural development.

Companies like Hi-Tech CADD Services provide support to architectural firms and developers to convert the point cloud models obtained from 3D laser scanning surveys into intelligent and information rich BIM. Existing buildings can hence become better, energy efficient, more apt in terms of occupant comfort and can be managed, maintained and operated in a better manner.
