In a rapidly changing world the complexity of infrastructural projects is increasing. These projects are often large-scale and multidisciplinary in character. The combination of Building Information Modelling (BIM), LEAN methodologies and concurrent engineering allows a more sustainable, safer, faster and more cost-efficient management during the design, construction, and maintenance of projects. The BIM department at Delta Marine Consultants Singapore supports these developments by playing a prominent role in the field of 3D / BIM models throughout the entire construction process.
We use BIM to create a virtual environment where we can simulate the construction process. We use BIM in the tender and construction phase.
This practice leads to:
- A cost effective concept that complies with the customer’s requirements
- A safe, relatively short and precise realization phase, with no fail-costs
- A structure that is maintainable throughout its lifespan
3D / BIM modelling
At Delta Marine Consultants Singapore we use BIM to create an intelligent, multi-disciplinary and multi-dimensional model of a given project. Delta Marine Consultants Singapore has modelling capabilities in the field of Structural Modelling, MEP, formwork, roads and earth works.
3D / BIM models are used during the tender phase to optimize the design and meet the client's demands. In the Design phase, the 3D / BIM models are then developed further to generate information such as, drawings, schedules, material take-offs, clash detection, program and cash flow analyses. During the construction phase these models will save a lot on time, construction cost and problems that might arise. New information will be added to represent the project ‘as-built’ that can be use in the future as an Asset Information Model. Facility Managers can rely on these models for the full duration of the facility. For the long term this model can be used for asset management purposes and performance analyses. To create the 3D / BIM models we use various software programs such as Revit, SolidWorks, Inventor, Civil3D, Allplan, Tekla, Infraworks, Vico, Autodesk Navisworks, and Solibri Model Checker.
Delta Marine Consultants Singapore supports the concept of open data-sharing solutions that would optimize design, construction and maintenance processes. We comply with international standards such as PAS 1192.
3D rebar models
Delta Marine Consultants Singapore supports the developments in structural modelling such as modelling concrete reinforcements in 3D. Adding reinforcement bar model to the BIM model can help the designer and contractor to better understand complex reinforced concrete details. That allows them to solve constrains and clashes already in the design phase of the project instead of during construction. The models remains fully integrated, intelligent and flexible up to the last stages of the construction process.
Point Clouds
At Delta Marine Consultants Singapore we use Point Cloud laser scans to further aid the design and construction processes. A point cloud is a collection of points in a three-dimensional coordinate system that is created as the result of a 3D laser scan. They can be made within a range of resolutions, which will define the accuracy of further use. Point clouds provide a fast way to map out the existing context or environment in projects (reducing cost due to more accurate design and project preparation), as well as to compare the as-built objects with the virtual 3D model. They can also be used to capture the progress of the construction. Within Delta Marine Consultants Singapore we have built extensive experience with using this technology on a number of projects.
Visualizations
Design visualizations are a powerful tool for communication with both clients and stakeholders. At Delta Marine Consultants Singapore we have extensive experience with creating photo realistic still images and fly through videos. These visuals help to understand the complexity of projects and visualize the design alternatives and optimizations.
4D Modeling
One of the most important advantages of using BIM is that several dimensions of information can be added to the project. 4D BIM adds the dimension time to the 3D / BIM model.
Based on the construction model, we can simulate and optimise the building process of the project in the safety of a virtual environment where all risk factors can be evaluated and communicated up-front. Together with the construction planning data, these simulations comprise a robust and reliable planning tool that ensures an efficient and fluent construction process.
Geographical Information System
A geographic information system (GIS) lets us visualize, question, analyse, and interpret data to understand relationships, patterns, and trends. Delta Marine Consultants Singapore has a standard basic set of maps that can be used for any project. A dedicated group of GIS specialists supports most of the Dutch projects with actual and reliable geographical information.
BIM 360 Field
BIM360 Field is a mobile application, specially designed for on-site work, which combines safety and building quality information in a single 3D model. Using this application we are able to review our digital models outside the office and compare them, while working at the construction site, with the physical structure. Traditional building practices require a construction worker to extrapolate a 3D image out of 2D technical drawings, which requires time and carries certain fault risks. With BIM360 Field a construction worker could directly view the model on a portable device and have access to all relevant information at all times. BIM 360 has proven to be a greatly advantageous building tool that contributes to a safer, more efficient and exemplary building process.
BIM Coordination
Delta Marine Consultants Singapore believes that with BIM we can build a better product for end users. BIM is assisting on being in control of the design and construction process and simulates the construction process to create a safer working place. When using BIM we coordinate the work between disciplines to create synergy and avoid duplication. Using BIM enables more efficient and effective collaboration.
To avoid construction conflicts the BIM model is used for clash detection and to manage interfaces. This allows the project team to work more efficiently and potential risks are identified at an early stage.
The BIM model is to be kept up to date in order to serve as a reliable basis for decisions during the life cycle of the project. This means that also during construction the BIM model acts as a central source of information. As all parties involved in the project have access to the BIM model, they will utilize exactly the same information. Consequently and as our experience has proven on numerous occasions communication then becomes much easier.
Virtual design
We have full 3-dimensional drafting capabilities and can make use of virtual construction model technology. A range of different 3D CAD tools is available for production of construction drawings, interface control and clash detection, integration of construction schedule, detailed material take-off lists, electronic survey data, visualisation, etc. 3D tools are used extensively to prepare roadway design, dredging and excavation works and complicated steel and concrete structures, and provide a framework for BIM.
