Got questions about BIM, our services or working with us? Let’s break it down below.
BIM basics
BIM stands for Building Information Modeling. It is a process that uses 3D digital models enriched with data to plan, design, construct, and operate buildings more efficiently. BIM enhances coordination, minimizes errors, and facilitates lifecycle management.
BIM visualizes designs, detects system clashes, plans construction sequences, and coordinates trades. Common applications include:
-Visualization & walkthroughs
-Clash detection (finding conflicts between ducts, pipes, etc.)
-Scope clarification
-Construction sequencing and logistics
-Design validation
-Marketing and client presentations
1- Select a pilot project to test BIM workflows.
2- Choose compatible software and hardware (e.g., 3- Revit, Navisworks).
4- Train staff in modeling and coordination.
5- Start with 2D conversions if no BIM models exist.
6- Gradually scale BIM use across projects.
A 2D conversion transforms traditional 2D CAD drawings (like DWG files) into 3D object-based models. This process involves digitally tracing 2D files and adding attributes to create a detailed BIM model. The time required depends on the modeler’s experience and project complexity.
Implementing BIM involves initial software, hardware, and training investments, but costs vary based on project size and company maturity. Most firms spend several thousand dollars per seat for software licenses (e.g., Revit, Navisworks) and additional training and hardware upgrade costs.
Key cost factors:
Software licenses: Annual fees for BIM tools (commonly $2,000–$6,000 per user).
Hardware upgrades: High-performance workstations and servers.
Training: Upskilling staff in modeling and coordination workflows.
Staffing: Hiring BIM managers or modelers if not already in-house.
Process development: Creating BIM standards and templates.
While upfront costs can feel significant, BIM often reduces rework, prevents costly clashes, and shortens schedules, leading to long-term savings. Many owners and contractors share implementation costs since both benefit from improved accuracy and coordination.
There is a growing consensus that all project stakeholders benefit from BIM and should share costs proportionally.
Designers gain clarity in coordination and fewer RFIs.
Contractors save on rework and sequencing errors.
Owners receive more accurate cost forecasting and better facility management data.
The delivery method and contract type (e.g., design-build, IPD) often determine how costs are distributed.
No, BIM and CAD are not the same. CAD (Computer-Aided Design) primarily creates 2D or 3D drawings based on lines and geometric shapes without 13.
Because BIM is a collaborative process, the entire project team would ideally be involved: the owner, architect, engineers, consultants, GC/CM and specialty contractors.
BIM Benefits
BIM provides measurable cost, time, and quality advantages for construction projects:
–Cost and efficiency benefits
Fewer errors and rework in the field
Reduced warranty claims and callbacks
More prefabrication opportunities (off-site fabrication lowers costs)
–Scheduling and logistics benefits
Improved construction sequencing and phasing plans
Ability to test “what-if” scenarios (site logistics, hoisting, schedule options)
–Design and visualization benefits
Clear visualization for non-technical stakeholders
Marketing and client presentation support
Early clash detection between systems (ducts, pipes, structure)
–Collaboration benefits
Better scope definition during bidding and purchasing
Enhanced value engineering through model-based analysis
About Our BIM Services
BIM coordination is the collaborative process of spatially aligning all disciplines involved in a construction project—such as architectural, structural, mechanical, electrical, and plumbing—by merging their 3D models into a single, federated BIM model. This integrated model allows project teams to detect and resolve clashes or conflicts before construction begins.
Using coordination software like Navisworks, BIM 360 Glue, or Autodesk Construction Cloud, teams generate clash detection reports, review issues, and prioritize resolutions. These are typically addressed in regular coordination meetings, where stakeholders analyze clashes, propose solutions, and align design decisions until reaching a sign-off-ready model suitable for construction.
MEP modeling refers to the creation of detailed 3D models for Mechanical, Electrical, and Plumbing (MEP) systems within a building using Building Information Modeling (BIM) technology. These models digitally represent how HVAC systems, electrical layouts, piping, fire protection, and other infrastructure components will be installed and interact within a project’s architectural and structural framework.
BIM Architecture software refers to digital tools used to create 3D intelligent architectural models fully integrated with parametric 2D drawings. These platforms allow architects to design, visualize, and document buildings with smart objects that carry real-world data, improving coordination, accuracy, and design efficiency. Popular BIM architecture tools include Autodesk Revit, ArchiCAD, BricsCAD BIM, and Bentley AECOsim, all supporting seamless collaboration across disciplines and enhancing the building design process from concept to construction.
In BIM, 4D refers to adding the time dimension to a 3D model, enabling construction scheduling and sequencing through visual simulations of project timelines.
5D adds the cost dimension, allowing project teams to link model elements to real-time cost estimates, budgets, and quantity takeoffs.
BIM Related Questions
The paradigm shift: BIM is changing the way we work. The typical top-down organizational chart won’t work for BIM because more collaboration is required. This becomes a barrier because old practices die hard.
• Technology & software – without industry standards and interoperability, it can be difficult to share building models. This poses a problem because BIM requires collaboration.
• Legal issues – there is a perception of increased liability within both the architectural and construction communities that is hindering industry implementation of BIM.
When implementing BIM, it’s common to face technical and cultural challenges. Here are some of the most frequent barriers:
• Fear of change: Concerns around legal risks, shifting workflows, or uncertainty about results are common at the beginning.
• Steep learning curves: Adopting new BIM software often requires training and time to master.
• Limited leadership support: Without buy-in from senior management, BIM initiatives can struggle to gain traction.
• Resistance from operational staff: Field or production teams may be hesitant to adopt new processes.
• High upfront costs: The initial investment in software, training, and implementation can be significant.
Plan and keep it simple and specific. Focus on tangible objects and avoid scope creep. Avoid implementing multiple projects before you have learned the lessons of using BIM on one.
Most importantly, don’t oversell BIM or make promises that you can’t keep.
Some firms find it helpful to have a BIM consultant assist with training and implementation.
A BIM steering committee can help the team stay focused on their tangible goals. Including senior management and end-uses can be an effective way to gain their buy-in and support.
BIM workflows rely on different types of software for modeling, coordination, visualization, and cost estimating. Not every firm needs every tool, but the most common categories are:
1. 3D Modeling Software (Core Design Tools)
Used to create and manipulate the building model.
Examples: Autodesk Revit, Bentley MicroStation
2. Engineering Analysis Software
Performs structural or MEP system analysis.
Examples: RISA 3D, Tekla Structures
3. Rendering & Visualization Software
Generates realistic visuals for presentations and client reviews.
Examples: 3ds Max
4. Coordination & Clash Detection Tools
Combines multiple trades’ models to identify conflicts.
Examples: Navisworks, Tekla Structures
5. Estimating Software
Connects model data to cost estimation and quantity takeoffs.
Examples: Sage Timberline, Graphisoft Constructor
6. Middleware (Data Integration Tools)
Links different software platforms for smoother workflows.
Examples: Innovaya, Avatech Earth Connector
7. Detailing & Fabrication Software
Creates detailed fabrication drawings and shop drawings.
Examples: Tekla Structures, SDS/2
At ENG we primarily use Autodesk Revit MEP with Fabrication Parts or SysQue, enabling accurate modeling for mechanical, electrical, and plumbing systems. Our team can work with ENG’s database or adapt to client-provided databases, ensuring flexibility and smooth coordination.
AutoCAD MEP is not a full BIM (Building Information Modeling) platform, but it can be to some extent. Especially when fulfilling a “BIM Spatial Coordination” requirement, you must deliver a 3D model of your specific trade/discipline for clash detection and resolution purposes. In this case, if you can deliver accurate geometry, you may get away without delivering a true parametric BIM model. Fabrication CADmep, however, has been the industry standard for more than 15 years.
A BIM Manager is responsible for leading the BIM Specialists and ensuring the successful implementation and coordination of Building Information Modeling (BIM) processes within a project or organization. This position requires participating in coordination meetings, maintaining communication with the general contractor (GC) and other trades, and overseeing team management, schedules, and overall project efficiency.
