Building information modeling (BIM) has been around for about 40 years now. Yes! You read that right – 40 years. Though in the 1970s when the concept was developed, BIM (as we know it today) wasn’t really implemented until the late 1980s. So I guess we can say, it has been a little slow taking hold. However, as time has zipped on and technology has improved, BIM implementation has rapidly increased.

Building information modeling started as a production of 3D design models to help catch architectural system variances and clashes. Since then, it has become an effective tool in project management and ever more prominent in job cost estimating.

Traditionally, estimators begin their process by doing manual take-offs or digitizing architectural construction drawings. Or possibly, they may be importing CAD plans into an estimating software package. The thing about these processes is that they all have higher risk of error by way of unknowingly incurring an omission or duplication. This has the potential to logarithmically propagate cost errors throughout the estimating process.

Using a BIM solution can significantly reduce (though not completely deny) human error. As the project experiences changes, as they always do, the model can be updated. If properly configured, the BIM should update the takeoffs, schedule, and costing data for the project as the changes occur.

After the BIM is established, pricing information is the next critical set of data which needs to be considered. Estimators can extract the quantities provided by the building information modeling solution and output the information via linking it to a product such as Sage 300 CRE. From here, an estimator may generate estimates based on historical data.

Some of the most critical tasks in estimating are having accurate and current takeoff information, and applying that to accurate pricing and scheduling data. BIM solutions can help to make the quantification tasks easier and more accurate. The integration of this data into an estimating solution can mean that estimators are more accurate and can spend their time and knowledge doing higher value activities.

Thursday, the Valley of the Sun Construction Financial Management Association held its monthly luncheon. Street Transportation Director for the city of Phoenx, Wylie Beaurup was the guest speaker.

He spoke to a packed house for more than 30 minutes about the city’s use of Construction Manager at Risk with Price Competition used by the state to dole out federally funded projects.  Beaurup is responsible for executing nearly $6 billion, 5-year capital improvement program.

Beaurup explained in order to be able to take advantage of the millions of dollars assigned to Arizona by the American Recovery and Reinvestment Act of 2009, state legislators had to change the language which outlines Requests for Proposals in Arizona.  In 2000, the state began using Construction Manager at Risk guidelines which do not allow for a project to be awarded by price.  It must strictly be awarded through qualifications.  S0, recently the state came up with the Construction Manager at Risk with Price Competition in order to begin using federally-funded stimulus projects.

Someone wanted to know if BIM requirements are going to be considered anytime soon when it comes to qualifying General Contractors for projects.  Beaurup’s answer was not really. At this time BIM knowledge might be advantageous but there are many more qualifications to be considered.  So at this time lack of BIM will not be used to disqualify those bidding for projects.

Bearup expressed his satisfaction with the Construction Manager at Risk model stating it ensures the most qualified contractor is chosen, not the cheapest.  It creates better relationships among team members, the contractor is involved for the duration of the project and makes for true value engineering.

 When asked if there were soon to be any RFP’s for Stimulus jobs, Beaurup told the crowd not anytime in the near future.
