The New Preconstruction

Posted by Holly Allison on Aug 25, 2010 6:54:00 AM

 

It just makes sense that BIM coordination, scheduling, and estimating should take place in one workflow. As your team works together to fix clashes, you also want to improve your estimate and schedule based on the newly coordinated quantities.

Otherwise, the typical process has every department working without the knowledge of changes that are occurring daily. This typical process meant gathering together to work out modeling questions, working on estimates, and every few weeks sitting around a table or GoToMeeting for clash detection meetings. The only problem with this set-up is that every two weeks, the offending trade would go back to their offices and fix their model and resubmit it so that they could cross that clash off their list. However, their fix could mean that two or three trades down the line now have a new clash to deal with at the next meeting. There was a vicious cycle of clashes begetting clashes.

We are proposing a new solution for the typical preconstruction challenges: one that gets subs on board early, one that involves the estimating and scheduling teams from the get-go; and one that includes clash detection, but with an interesting new twist: an integrated workflow for coordination by location which includes coordinated quantity counts for the schedulers and estimators.

Why does an early and integrated approach to constructability analysis make so much more sense for preconstruction and operations teams?

 

1.)  If your contract documents are 2D drawings then they need to be compared first so that the 3D models are verifiedd as being accurate. By collating and comparing these drawing sets for any changes, we can eliminate versioning errors with the models.
2.)  When it comes to coordinating the 3D models, the best practice is to do it as early as possible.  And the  best practice incorporates coordination, estimating, and scheduling and works with the popular model-authoring tools like Tekla, ArchiCAD, and Revit
3.)  Understanding the construction sequencing and workflow, preconstruction planning can be improved by using LOCATIONS.  This helps eliminate the ripple effect of fixing one clash only to produce three more clashes in its wake. And by sequencing the trades properly in the Schedule, we can also improve their flow through locations, greatly improving their ability to deliver on time with high quality.
4.)  Now using the coordinated models for scheduling and estimating means that the quantities per location are accurate and viable immediately for the estimating and scheduling teams. The new preconstruction means three disciplines working together in one workflow. Which makes us beg the question, “Why wouldn’t you extend BIM to 4D and 5D now that you’re investing the time to build 3D models?”


Of course, Owners are savvy and can still use the downturn to ask for hard bids. But progressive Owners understand that a comprehensive preconstruction effort means a better project in terms of budget, schedule, and quality. For those Owners who know the difference between spinning models on a screen and using the model to optimize schedules, answer budget questions, and deliver a quality product, the new preconstruction methodology makes perfect sense: coordinated models feed updated quantities to scheduling and estimating; subs are involved early resulting in more off-site prefabrication; and the integrated workflow keeps everyone on the same page.

Find out how you can revamp your preconstruction process and take BIM to 4D and 5D on the next Fridays with Vico.

5D estimating starts with a robust construction quantity takeoff.  With these construction quantities, you can drive a precise estimate and schedule.   And with the easy visualization of the model, you can quickly see which elements have been costed already, and which elements still need attention.  And it also allows Owners to see which/how areas of the building are contributing to the total cost of the building.

 

The estimate lives and breathes throughout the project as the design moves through iterations.  As the level of detail increases in the model, the estimate hones in on the final number.  

There is a common misconception that BIM estimating fully replaces traditional estimating practices. In reality, it is just a different type of input to a traditional estimating process. The input from model elements that are available is very accurate, but you cannot expect everything that needs to be estimated will have a quantity that can be extracted from the average model. Even what is there needs to be checked by the estimator to make sure the elements creating the quantity data are modeled as expected. For example, the quantity takeoff algorithms are not designed to eliminate the need for validation and we anticipate some corrections will always be required, especially on sloped, organic, or non rectilinear objects in the model or objects missing required meta data like reference lines.

A BIM model that contains the 3D geometry, the 4D schedule, and the 5D costing information looks exactly like a 3D model. It just so happens that if you click on any element within the building, you see its costing data, the quantities, the specifications, etc. With this depth of information, you can ask the model: how would the cost and schedule change if we substituted glass block for walls, or upgraded the lobby tile floor, or alter the pitch of the roof?

Ultimately, it is the BIM's job to facilitate the collaboration between the Owner, the Architect, the General Construction, and the Subcontractors.

Coordination 2.0

Posted by Holly Allison on Jun 6, 2010 7:51:00 AM

We are all witnesses to the transformation brought about by Web 2.0. Subscribing to blogs and watching video tutorials on YouTube has become commonplace - just like participating in a conversation in your favorite LinkedIn group.

 

With 50% of all General Contractors utilizing some piece of BIM, it’s time to take a second pass and refine what’s working. Clearly, 3D modeling and clash detection has crossed the chasm and everyone can agree that there are tremendous efficiencies to be gained from the process. But what if we could improve upon the process, improve upon the end result?

 

With multi-disciplinary teams working together, we need a different approach to coordination - a different methodology - Coordination 2.0 if you will. Using this approach, not only do we work to the goal of zero change orders due to coordination issues, but we also have a coordinated whole model for use downstream for scheduling and estimating, installation, production control, and even facilities management.

 

The coordinated model doesn’t get filed away. The coordinated model becomes the key to alternative contract types; it becomes the trigger for more precise quantity takeoffs which then drive more precise schedules and estimates.

While other solutions can be complex, especially managing layers and model versions, Vico Office Constructability Manager offers a simple, integrated solution within the award-winning Vico Office Suite. Coordination is a necessary part of the BIM roadmap - that’s why Vico has developed a new approach which incorporates an effective workflow for identification, promotion to RFI, reporting and resolution.

 

To simplify coordination efforts, Vico Office Constructability Manager collects all relevant object clashes and produces only one item per clash. The workflow allows users to define the elements and layers for consideration; detect and filter the clashes; promote important clashes to Constructability Issues; and then submit, prioritize, and assign RFIs, advancing only the unresolved clashes as Change Orders. As we’ve learned from our customers, "BIM doesn’t end with clash detection - coordination is just the beginning for quantity takeoff, cost planning, scheduling, and production control.

 

Vico developed the software based on our own experiences working on over 350 BIM projects worldwide. Along with our coordination meeting methodology, we believe Vico Office Constructability Manager helps keep project teams focused on the end goal: a solid end product that meets budget, schedule, and program.

Watching this webinar with your team, you’ll learn:
• Vico Office’s simplified approach to model management, ensuring
  that you are always working the correct model and the correct version;
• How to filter layers and elements to discover relevant clashes and
  focus on the most important ones during your coordination meetings;
• How to classify your detected clashes as Constructability Issues;
  preparing only the most relevant items for coordination meetings;
• How to escalate Constructability Issues to RFIs, producing snapshots,
  measurements, and other relevant data for an RFI report, again
  prioritizing and assigning;
• How to promote RFIs to Change Orders;
• Prepare powerful reports using the integrated VO reporting engine.

 

But Owners don’t want to pay for models that are “less bad.” As far as they are concerned, they’ve already paid for a coordinated building. Owners want to realize an ROI from BIM that goes beyond the cost AVOIDANCE of clash detection to a true realization of schedule compression, and therefore, cost REDUCTION. That’s the difference that Vico Office brings to the table.

 

Just as with Doc Set Manager, Vico’s solution for collating and comparing thousands of 2D construction drawings, we have developed a special licensing schema that support multi-disciplinary project teams. Simply put, you can share licenses of Vico Office Constructability Manager with your design team, engineers, subs, and even the Owner. And when Constructability Manager is paired with Doc Set Manager and Vico Office Client, Vico’s own coordination methodology for geometry and scheduling, a complete 2D to 3D to 4D to 5D solution is established. The value of Vico Office’s integrated clash detection is that the cost and time impact of these issues can be quickly calculated and used to improve project results. Combining Doc Set Manager for all 2D clash detection and Vico Office Constructability Manager for all 3D clash detection, Vico offers a powerful solution no matter what type of documents or models you have.
