What We Do For General Contractors
By adopting BIM in projects, It helps contractors to increase the quality, productivity, efficiency and safety of their projects. It also helps contractors to make better material choices, it streamlines the construction work and helps to minimise the human errors that may occur during construction. By improving the planning stages, BIM can help contractors reduce the number of wasted materials and reduce reworks as well. Therefore, it can result in reduced costs.
3D Modelling and Coordination
DDG has hands-on experience in creating BIM models from scratch. We create 3D models from inputs such as PDF markups, AutoCAD or Point Cloud files. With regards to co-ordination, we help to collaborate between MEP engineers, structural engineers and architects.
Clash detection & reporting
Once the models for various disciplines are developed, we perform clash detection using industry-leading software tools and generate customized clash reports for each trade. Clash detection can accelerate the coordination process between disciplines by identifying issues between models faster and more thoroughly.
Resolution & support
DDG works with Architects, Engineers to help in the design development stage. During these stages, we help to resolve the clashes and implement the agreed changes in the models to create coordinated models. We also give suggestions for the designs. This results in a reduced number of change orders. The change in the model is visible to the whole team and fosters collaboration between the contractor and other stakeholders.
Constructability review
DDG's BIM-based Constructability analysis will help the general contractors to review construction processes/methods during the design phase and identify potential obstacles and design flaws that might result in schedule delays, cost overruns, rework, etc. As the project goes on the identified issues will be fixed by us.
Accurate Project Bids
We help contractors to develop accurate bids using BIM by accounting for the quantity of materials, systems, costs, and other nuances. The process not only leads to higher bid accuracy but also makes it faster.
4D Construction Sequencing
By federating different trade 3D model representations, DDG is capable of producing intelligent 3D visual construction programmes. During the early project stages, 4D models can be used by the delivery team to view the forecasted time-based processes.
This 4D construction sequencing combines 3D models with project programmes, creating an intelligent visual construction timeline. Being able to interrogate a 3D graphical representation of the proposed project programme, enables the project delivery team to identify and resolve previously obscured logistical issues and potential health and safety issues.
5D BIM Simulation
Using 5D BIM, or five-dimensional building information modelling, DDG can do the real-time extraction or development of fully valued parametric building components within a virtual model. It allows experienced users to create models that demonstrate how changes to materials, layouts, square footage and other design elements not only affect the appearance of a facility, but also the cost and schedule of construction
Facility Management & Operations
BIM’s role in facilities management is to provide quantifiable insights.
As we have all heard, BIM is changing the way in which buildings are designed and built, but it is important to emphasize that this methodology also affects how these buildings are managed and maintained.
DDG can take all the different data sources and combine them all together into one 3D model with access to all building data and associated manual of operations, Manufacture specs, Equipment catalogues images etc. We use BIM 360 cloud-based platform so contractors, owners and maintenance crew of this model can access the building from anywhere simply with internet access.
Scan to BIM | Point Cloud to BIM
Using the point clouds obtained from the 3D laser scanner, DDG creates a Revit model that varies from LOD 200 to LOD 400 as per the point cloud to BIM services specifications and scans to BIM standards. Let the purpose be building renovation or refurbishment, we can create an information-rich Revit BIM model. The point clouds can be from any sort of latest 3D laser scanners. For example, Trimble, Reigl, Leica, Faro etc. We have experience in creating the Revit models from point clouds for architectural elements, mechanical, structural, electrical & fire fighting equipment.
Our point cloud services include:
- Scan to 3D model for architectural & structural components
- Point cloud to MEP BIM modelling
- 3D scan to CAD
- Scan to construction drawings
- Point cloud to Revit
- Coordinating between different trades to best optimize the use of existing space
We also provide solutions in enabling coordination of existing structures with a new one or to create a topographic map of the data for the retrofitting of facilities.
So far, we have seen the below benefits of this technology:
- Laser scanning to BIM contributes to transparency, communication and collaboration.
- The 3D model derived from this technology improves performance, quality assurance and reliability.
- This technology greatly helps to reduce the budget.
- Any change in the model can be easily made and decision-makers can quickly make decisions.
- It enables sustainable structures to be created.
- In the early stages of the project life cycle, errors can be avoided, and rework costs reduced.

BIM Audit Services
It's a standard industry practice to get your BIM model validated and DDG offers to assist with its third-party BIM model auditing service. If you already have a BIM model but are unsure of its quality or want more level of detail added to it, then we can conduct our elaborate BIM auditing process for you wherein BIM models undergo our stringent quality tests to meet the industry level standards.
Our in-house developed tools can search and identify all components & materials missing from the model, helping you to solve these issues in advance. We can also help locate flaws and exceptions in models made by different design teams. This would help avoid expensive rework, ensuring elements of both the models' match. We can help validate your BIM models at key points throughout a project. This audit process helps to provide assurance that your BIM model will provide reliable output data and, thus, generate correct and relevant reports.
Our BIM Audit Checklist includes:
- Compliance with BIM execution protocol
- BIM capability assessment for all the scope of work involved in that project
- Model accuracy verification against the design intent
- Adherence to local Building codes
- All drawing and other schedule outputs have been managed per the standards and requirement
- Are regular Model Review & Model Checking procedures being followed and reported?
- Federated Model being used for 3D coordination & clash detection
- Federated Model being used for sequencing, programming & planning (4D BIM)
- Federated Model being used for quantity take-off and cost control (5D BIM)
- Models being used for performance analysis (6D BIM)
- Structural Analysis
- Energy Analysis
- Lifecycle Cost Analysis
- Operational Asset Information Models for Facilities Management (7D BIM)
Revit Family Creation
BIM families creation requires specialized expertise as each and every element of the family has to be modelled, keeping the geometry of the family at the core. Our BIM Library creation services for building product model catalogues to the architect, engineer, fabricator and manufacturer. Our Revit Family provides detailed information about a physical product. Components object and Material/Layered objects are two types of BIM objects.
Our Revit family creations services include:
- Architecture family creation
- Structural family creation
- MEP family creation
- Building system families
