A recent survey conducted with the top AEC (Architecture, Engineering and Construction) companies shared a valuable insight. According to the report an estimated $17,000 per clash saving is achieved through clash detection in BIM. When working on an engineering project, during the design stage, you might’ve encountered an error “Lines/Objects cannot intersect each other”. This message notifies a possibility of a clash in your design. However, why does clash happen? And can we solve it by using BIM (Building Information Modeling)? Let’s find out.
How does a clash happen?
In a scenario where two or more objects/design elements in an engineering model coincide with each other, resulting in a clash. Clashes are categorized as geometry based (like steel rods passing through walls), design schedule based, or can happen as per the design changes and updates to 2D drawings.
Please check out embedded images showing clash detection in BIM modeling projects that were undertaken by Russell and Dawson as part of their architecture design and engineering services.
Can clash detection be solved using BIM?
BIM is handy for detecting element clash by automated rules and workflows. BIM identifies the models by inspecting the objects and elements used in various models and generates a detailed report showcasing clash detection. Many AEC organizations realize the benefit of reduced risk, cost-saving, and efficient models for BIM clash detection. A typical BIM model consists of structural, MEP, AEC, piping and several other models, making it necessary to check the occurrence of a clash.
BIM clash detection helps to reduce the human errors, save high cost and schedule implications without visiting the site. Take for example in the construction industry where a concrete wall is built using steel rods. In a construction design model, the concrete wall and steel rod are two objects, and they superimpose each other making it difficult to detect clash. BIM understands such composition and simplifies the detection of conflict by analyzing the construction models.
Clash detection in BIM delivers three main types of clashes:
Detecting a Major or Hard Clash:
BIM modeling software alerts the user when two objects pass through each other by using clash detection rules based on embedded object data
Detecting a Minor or Soft Clash:
When any design element/object encroaches into geometric tolerances for other objects like modeling a building near a high tension wire, BIM notifies the user
Detecting 4D/Workflow Clash:
It helps to resolve the clash when an abnormality occurs (like when the work crew arrives on site when there is no equipment)
How Clash detection in BIM is used across the AEC and EPC Industry?
Here are two ways to detect clash:
By integrating BIM with design software:
Autodesk’s Revit is one of the most widely used engineering modeling software. Clash detection can only work on the models developed by proprietary software. Let’s understand this by taking an example of a construction design model where while adding a slab on a set of walls which do not make contact with each other. By integrating BIM with Revit, it notifies the user in the event of a clash.
Using BIM Integration Tools:
There are many companies which do not use proprietary software, and it becomes difficult to detect clashes. BIM integration tool helps such organizations to identify clashes on models built using the non-proprietary software. For example, after integrating all the Revit design models into a BIM modeling, a change made by the Structural Engineer using Navisworks will reflect in Revit design during clash detection.
Clash detection in BIM modeling is the best and smartest way to prevent problems in communication, coordination and execution of the AEC project. Preventing those problems would improve efficiency in time and cost
Clash detection implementation during design phase will deploy projects faster while during construction phase it will certainty transform the project outcomes.

Lean construction is derived from the concepts of lean manufacturing, and it combines operational research and practical construction design development. Many lean manufacturing practices and principles for end-to-end design are implemented in the lean construction process. To simplify, lean construction is about managing and improving construction process to satisfy customer needs and achieve quality, schedule delivery, safety and profitability.
Why Lean Construction?
There are three key priorities in any construction process:
- Keep the work flowing so that the workforce employed are always productive
- Reduce inventory of tools and materials
- Reduce waste and inefficiency inefficiency
To simplify, optimal usage of materials, time and efforts are crucial in the construction process for generating value in the process. Moreover, for any project, the system needs to collaborate business owners, AEC, contracts, facility managers, workers and various other teams at the early project stage. Lean construction identifies the gaps and aims to benefit the overall construction plan.
Lean construction follows the lean production approach, but it is differently perceived during practical implementation. Various workflows are integrated into the construction planning process to align the supply chain to maximize the value and minimize the waste. Toyota and other such companies have pioneered the lean model using TQM, SPC, and Six-Sigma to meet customer demands and improve business profitability.
How to implement Lean Construction?
We can implement Lean construction by using CPM and work breakdown structure. Other tools and methods are also used like Last Planner System, Target Value Design, and Lean Project Delivery System.
There are also toolkits available to implement Lean construction like:
- Lean Design: BIM, A3, Process Design, Kanban
- Lean Supply: JIT, 6S
- Lean Assembly: Value Chain Mapping, Visual Site, Daily Crew Huddles
The lean principles can be implemented entirely and efficiently by focusing on refining the whole construction process. It requires all teams, stakeholders to be committed, involved, and work to overcome obstacles that may arise from traditional contractual arrangements.
Each departments need to follow below guidelines:
- Clear communication of project plans
- Training the team to improve teamwork and multi-skills
- Daily progress reporting and improvement meetings
- A well-motivated, well-trained, flexible and fully engaged workforce
- Leverage Virtual Reality or 3D design to adequately visualize and define the project requirements from the customer’s perspective
- Value Management to get better clarity and focus on client value
- Use of integrated design and build arrangements (including partnering) to encourage close cooperation between designers, constructors, and specialist suppliers
- Design for Standardization and Pre-assembly – both of components and processes to achieve higher quality and cost and time savings.
- Supply chain management and rationalization of the supply chain to integrate all stakeholders to contribute to delivering the overall customer value
- Transparency of costs – elimination of waste in both processes and activities requires a clear and complete understanding of costs to ensure right decisions on customer value.
- We must address confidentiality of expense and cash flows
- Eliminating the boundaries between companies by partnering and getting more contribution to achieve a common goal
For Construction Planning:
- Establish ‘best in class’ construction methods and outputs
- Formation of a stable project program, with precise identification of critical path
- Risk management – to manage risks throughout the project
- Just-in-time delivery of materials to the point of use eliminates the need for on-site storage and double handling

As we say goodbye to 2017 and head into a new year, let us understand the trends that will be impacting architecture, design and construction industry. As you read further, you will find that some of the trends shared below are not brand new, but their relevance is of utmost importance in current “latest” trend. Other construction trends are further out in the future, and may never materialize. Take a few minutes and ask yourself some simple questions:
- “How can my company effectively respond to this trends to remain competitive and even gain a competitive advantage?”
- “Will this trend impact our industry?”
- “Will this trend specifically impact my company – or my clients?”
Top 5 Architecture Design & Construction Trends in 2018
Prefabrication and Modular Construction become Mainstream
The previous trend was about the need to improve construction productivity. Prefab and modular construction are an excellent way to do this. One of the classic example of this trend is The Great Pyramid of Giza. Where its outer limestone blocks were cut ten miles away and were transported upriver, making prefabrication popular since ancient times. However, in recent years this trend has been picking up in use and acceptance. Case in point: a mechanical contractor that has adopted a manufacturing-style approach, utilizing prefabrication and modular construction to build much of a given mechanical system in their shops, and then transport the modules to the project site. Electrical contractors and drywall installers have seen the benefits of this approach. They are now regularly asking the mechanical contractor to incorporate conduit piping and drywall hangers into their assemblies.
BIM (Building Information Modeling) Continues to Evolve as Firms Integrate 4D, 5D, but 6D Remains Elusive
As per a recent survey, in the last three-quarters, every A/E/C firms have been involved with at least one BIM project. But the reality is that many mid-sized construction firms still have no BIM experience. They may have be “involved” in a BIM project; by outsourcing to RDAEP for designing in Revit, but then went old-school with 2D drawings and specs. There was no use of implementing the building model during construction phase. The concept of owners integrating building models for Computer Aided Facilities Management (CAFM) is still not mainstream. The primary reason is not having a qualified staff. Companies don’t understand the value of the model post-construction.
RDAEP helps such companies by architecting the designs and developing models using AutoCAD and engineering software. To respond to the growing prevalence of Building Information Modeling, many countries are seeking to implement national standards. In the United States, a number of organizations, firms, and government agencies have partnered to develop the National BIM Standard-United States (NBIMS-US).
Protecting Coastal Cities Becomes Priority
The New York Times recently published an article about investors shying away from coastal real estate, like in areas of Florida facing increasing king tides. An article in the Scientific American noted that the sea level rise over the coming century could be the highest in human history, with the east coast of North America baring much of the brunt. Some scientists have revised their sea rise forecasts upward, and are now projecting that by 2100 many coastal cities will be abandoned.
Now the question to ask is How will governments respond? How will they protect such heavily populated cities like New York and Miami? Where will the funds come from? With many recent natural disasters happening worldwide, the trend of safeguarding coastal cities has gaining priority. But as time passes, its importance recedes like the tide. Hurricane Katrina and Superstorm Sandy brought this trend to the forefront of the national consciousness. New natural disasters like Autumn hurricanes stir new fears.
Profitability Continues to be Thin for Many Firms
PSMJ Resources just reported that based upon their 2016 Circle of Excellence data, the top A/E firms are exceeding 35% profit. But a lot of design and construction firms still struggle with low margins. There are scattered anecdotal evidence of A/E/C firms working for cost to keep staff busy. Certainly, things are better than they were during The Great Recession. Those areas heavily dependent upon the energy industry and fracking, the past few years haven’t exactly been boom time. Third-party facilities management are increasingly bidding out professional services. Productivity, New delivery models and Innovation are the three important pillars to become profitable.
Evolution of Project Delivery
According to this article by McKinsey, manufacturing productivity gains have outpaced construction productivity gains by 1.7 times since 1994. Furthermore, construction productivity has slightly declined during this time. The article refers to several factors for this: poor organization, inadequate communication, flawed performance management, contractual misunderstandings, missed connections, poor short-term planning, insufficient risk management, and limited talent management. Any of that sound familiar? In recent years, very few A/E/C firms have been directly involved with PPP (Public-Private-Partnership) funded projects. Still there’s a lot of work to be done. With IPD (Integrated Project Delivery), an interesting concept that combines having a fully-integrated team with risk/reward sharing on a given project, has been gaining huge acceptance in the coming years.

As per the recent insight shared by IE School of Architecture and Design, the urban population is expected to double in the next 40 years, forcing cities to undertake a holistic and sustainable transformation of their model. One of the most significant challenges in architecture is to optimize its current capacity for developing denser metropolitan cities and areas to offer residents a better quality of life.
Architectural design firms typically work on many small and large number of projects with outcomes that are hard to predict. Frequent changes in the requirement disrupt the normal course of activities. The design teams must be able to align at all times.

Every construction project starts with a vision and real need is to transform that vision into a reality. One of the most important decision is about choosing an architectural company or a design firm fitting both project needs and at the same time making financial sense. The most methodical way is to formulate a RFP and send out RFP to all architectural design companies/firms and evaluate their responses based on following three criteria.
The most important aspect when selecting an architectural and engineering design firm. Experience speaks a volume, how long they have been in the business and how many projects they have executed. The architecture company having diverse project experience and credentials will do the job for you. There were times when decisions were taken to hire a big firm but not any more, now who can do the job or fit against the needs.
What you need to make sure is firm’s expertise and how well that specific expertise fits into your needs. The firm providing comprehensive services will show you their past and ongoing project works and will provide customer references for you to talk to them.
You need to discuss and evaluate following with company, you need to make sure how good is the company in their deliverable
- Schematic design
- Design development
- Construction documents
- Selection or complete management of sub-contractors
- Bidding or negotiation
- Construction Administration
What are some of the questions you should ask, here is a brief list
- What types of services do you offer? Are you open to providing a la carte services that I need?
- Will you design to a budget?
- What is your experience with energy-efficient design, green building, affordable design etc.?
- What kind of collaborative tools that you use for client communication?
