Spotlight on Becher Neme: BIM Expert Pushes a Zero-Change-Order Approach

By Akio

The team that makes up Neme Design Solutions, a Long Beach, California-based BIM consultancy, specializes in simplifying highly complex projects to enable fabrication.

Led by founder Becher Neme, the firm includes a small team of architects and engineers with more than a decade of experience working onsite with general contractors, and with particular expertise in the CATIA solution.

This combination of field experience and software knowledge has helped the firm carve out a unique niche in model clash detection and resolving interface challenges.

Yesterday’s Improvements Are Today’s Inefficiencies

While Neme notes that the AEC industry has flocked to BIM as a means for improving construction efficiency, the tools commonly used require certain sacrifices.

Case in point, one of the firm’s primary services is coordinating clash detection among BIM models. Today, most general contractors launch a project by meeting with all of the trade contractors.

Dozens of people bring their 3D models and, through a seemingly endless series of meetings, they run clash detection to find potential conflicts among systems. When conflicts are found, each model is updated with the solution.

Neme left these meetings wondering: how much time is invested in preparing for these meetings? How much money is spent on getting all parties involved on the same page? If BIM is about providing project efficiency, how can this process be made more efficient?

A Single-Source Solution

While clash detection can be easy, there’s value to be gained in resolving these conflicts more efficiently. To do so, Neme Design Solutions has explored the single-source model concept.

The idea is that Neme Design Solutions works with the general contractor to create an accurate BIM model before subs are brought on board. A small, highly skilled team creates a highly accurate model. As much as 90 percent of the conflicts can be resolved at this stage.

Next, the trade contractors are brought in. Rather than resolving hundreds of modeling conflicts, this wider group fine-tunes the existing model before moving directly to fabrication and installation.

The Peak of Precision

This single-source solution is already in action on several of Neme’s projects.

Among them, the Anaheim Regional Transportation Intermodal Center required the high-precision work for which the CATIA software solution is best known. The project features a highly complex ETFE roof with more than 3,000 connection components.

The roofing contractor brought Neme Design Solutions onboard when the sub determined its software could not handle the roof’s intricate geometry.

By developing a comprehensive, single-source 3D model, the roofing team was able to extract fabrication drawings so accurate that only four of the 3,000 components ultimately needed changes.

But it is Tivoli Village—a mixed-use development in Las Vegas—that perhaps best demonstrates the unique benefits possible from single-source models.

General contractor Hardstone Construction took complete charge of this 2 million square foot project. As part of a small team of CATIA experts, Neme was deeply involved in developing a single-source model for the project. He rendered the MEP part of that model to be conflict-free and ready for installation.

With the help of this process, the $350 million first phase of the Tivoli Village was so efficient that it had virtually no change orders. The general contractor was able to beat the budget in several areas.

Next Generation Possibilities

Given the promise of single-source models, Neme is looking to what might soon be possible.

The next generation, he suggests, must move 3D models beyond visual representation and conflict resolution tools. Future models should improve installation workflow onsite, further optimize prefabrication, reduce material waste and raise onsite safety standards.

For Neme, CATIA is far and away the preferred platform for creating complex, yet flexible, models. However, he notes that given Dassault’s game-changing results in the aerospace industry, expectations are high from construction players on what the software company can do to transform their standard processes.

Neme notes that the latest update to Dassault’s platform boosts the software to a truly collaborative tool. The cloud-based platform allows project teams to work live in a model from anywhere around the globe. Updates are instantly visible to the entire team.

This capability allows the specific skill set offered by Neme Design Solutions to be available as-needed worldwide, and allows Neme and his team to work on multiple projects across the world at once.

Where to Learn More

Looking to learn more about single-source models? Consider attending this year’s 3DEXPERIENCE Forum in Las Vegas, November 11-12, where Neme is a returning speaker.

For Neme, the event is a must-attend for anyone interested in innovative solutions, as it exposes attendees to how the technology currently being explored in construction is being used in aerospace, industrial design, medical and other highly successful industries—suggesting new possibilities for how construction can move forward.

Flip the Script: Ask Planning Questions in This Order for Better Project Outcomes

By Patrick

Architect in field

When architects and planners work with owners, they usually accept a proposed site and think about how to arrange and orient a building on that site.

They develop ideas about what the building should look like in some detail before engaging builders or construction managers in ideas about how the building will be delivered.

Then, if the project cost cannot be brought in line with the budget, another site or an existing building renovation is considered.

AEC teams tend to think first about what to build, then how to build, and finally where else they should think about building.

Perhaps this is the wrong sequence of decision-making and engages the team members in the wrong order.

in a better order for better project outcomes”

What happens if we reversed the sequence? Can a where-how-what sequenceconsidering multiple sites, new and existing buildings, and logistical delivery issues before thinking about the appearance of the buildingdeliver a better result?

(In manufacturing, how a product will be made is just as important as what it looks like, therefore delivery issues are considered from early in the design stage.)

The minimum information required for considering alternative locations and options are:

  • the owner’s requirements, or the space program
  • code and zoning constraints that might differ by location
  • construction cost differences and schedule implications by location

To find the best location, we need a data driven decision-making process that updates space program alternatives against multiple locations with multiple code constraints.

Note: This is a process enabled by an interoperable BIM Level 3 system; it is not possible with disparate data across multiple BIM Level 2 point solutions.

where-how-what approach allows the focus to be on the process of delivering the project, not primarily what it could look like.

With sufficient data to determine if a certain location will permit a facility to be delivered more quickly, or managed more efficiently, an owner can make an informed decision to prioritize project value over the appearance of a building.

Owners rely heavily on the recommendations of their design and construction team, but this advice has traditionally been based on experience rather than objective data.

space program alternatives for multiple location options”

When building owners collaborate with finance teams, they benefit from data clearly presented in models that can be updated instantly to compare different scenarios.

Design and construction delivery decisions, by contrast, are made mostly on faith that the opinion of the planning team is correct. In this sense, owners have not been able to directly participate in a truly rational and objective decision making process.

Construction projects that leverage cloud collaboration, 3D models, and interoperable data can predict implications of choices early in the process, enabling owners to make the right where-how-what decisions to support their long-term objectives.

How Lean Construction Practices Are Decreasing Schedules for Contractors

By Akio

McGraw Hill Construction, the Lean Construction Institute, and Dassault Systèmes teamed up to produce an in-depth report on Lean Construction. Below is an excerpt from that report on the the impact Lean practices are having on contractors in regards to scheduling.

Construction Manager


The Impact on Contractors of Schedule Decreases Due to the Adoption of Lean Practices

Reduced project schedule is one of the top benefits of adopting Lean practices, and saving time in the construction industry also cuts costs on projects and can increase profitability.

However, the savings only accrue to the contractor if the owner has not already factored the reduced amount of time into their expectations of the contractor, especially in the case of a negotiated project, or if the contractor has not deemed it necessary to build those cost savings into their bid in order to win a project in a highly competitive market.

The study results suggest, though, that these options are not mutually exclusive. About two thirds of contractors report that the schedule savings they experience due to their Lean practices do have a positive impact on the profit they experience in their projects, and just about the same percentage of contractors report that they are able to bid projects more competitively due to the schedule savings.

Tweet: “About 2/3 of contractors report that adoption
of #LeanCon allowed them to bid more competitively”

Clearly, there must be significant overlap of firms who both have schedule reductions feeding their bottom line and schedule reductions absorbed in their efforts to be more competitive.

However, the findings also reveal that the industry is nearly unanimous about the growing expectations of owners that projects can be done in shorter time frames due to the adoption of Lean practices in the industry.

done in shorter time frames due to the adoption of #LeanCon”

This aligns with the previous finding that increasing their firms’ competitiveness rather than direct profits is the larger benefit from Lean.

The in-depth interviews with Lean experts shed further light on this finding. Experts report that, even just five years ago, most owners were not familiar with Lean, but they see a broad change occurring.

Some believe that owner mandates will be the most critical driver of Lean construction in the industry in the future, a shift from what they currently see occurring, other than in one or two sectors like healthcare with engaged owners that have led the industry on Lean adoption.
