It’s always interesting to see some statistics that back up claims about products and processes. The enthusiasm over Building Information Modeling (BIM) has often been punctuated by claims that are drawn from logic and extrapolation rather than actual experience.

Holder Construction built the recently-opened Aquarium Hilton Garden project in downtown Atlanta finishing it in March 2008. According to a press release put out by Vico Software, makers of 5D Virtual Construction software and attendant services, the project achieved some collaborative and economic results.

Everyone on the team had the chance to literally walk-thru the building before a bucket of dirt was moved. But where the process really hit some savings was in the reduction of change orders by eliminating “collisions” that result from design discrepancies. You are all familiar with them, and some of them sound like this when the people doing the work are bringing them to your attention:

HVAC needs to move the duct work three inches to the left so we can get a conduit through there.

By using BIM for this project it is claimed that 590 collisions were avoided and that saved $800,000.

I’ll bet a lot of people got new tape measures out of that deal.

Here are some interesting web tools, and one thing on the horizon, that promise to make the flow of construction project information quicker and more accurate.

If you’ve been thinking about bringing together all of your communications efforts there are some companies that are making that easier. The idea is to have all of the information about a project readily accessible to all the people who need access to that information. Construction is an especially onerous business to do that with since there are so many document variables. Still, it appears some are taming what would otherwise be a fairly tangled mess.

Projectmates is online project management software that claims to allow internal and external teams to share drawings, documents, meeting minutes, discussions, budgets, invoices and more with just a web browser. This is a seven-year old product that uses 40 different modules and is available to rent on a per-project basis, or with a dedicated server provided by them, or as an in-house solution that you purchase. From a wireless perspective it works with Blackberry, Palm and Microsoft Mobile 5.0.

Embracemobile says that recent reports claim 25 percent of construction costs can be eliminated by the efficient transfer of information. The company uses a platform that combines wireless, web and palm technology (they use that in lower case so I’m assuming they mean handheld devices in general) to enable remote workers to access and supply information in real time. The company claims you will enjoy benefits like the elimination of phone tag; having more accurate and timely data; having fluid items like reports and schedules accessible in real time; admin staff freed from data entry and sending information; and reduced travel to and from sites.

Esquiggles says you can increase productivity by 20 percent per day by incorporating remote data entry that updates things in real time. This company uses modules so you can select the level of sophistication you want. For example you could start out using an electronic data collection and client portal and later you could add the bill of materials module and others. This particular solution appears to have a very robust forms capability that includes form designing options. For creating reports and other documents the data collected can be transferred to a standard company template with the click of a button.

In the field all of these systems require at least one hand free to handle the handheld device. But a research team with the Canadian National Research Council’s Institute for Information Technology (NRC-IIT) is working on a way to enter data using speech. They have created a multimodal field data entry (MFDE) application to help with data collection during concrete inspections. The researchers say that if workers are are using instruments or taking measurements they can use speech to enter data or information at the same time. While background noise was somewhat of a problem the researchers have gone back to the drawing board to identify a better microphone for the application. Even with the noise issue respondents claimed they were able to complete tasks faster while at the same time being able to be more aware of their environment.
