This course introduces the types of cost estimation from the conceptual design phase through the more detailed design phase of a construction project. In addition, the course highlights the importance of controlling costs and how to monitor project cash flow. Students will work on a break-even analysis of construction tasks in a project.

Finally, some next steps.
What is that we're seeing within the industry?
Things move at a pretty quick pace as it relates to technology.
Construction moves a little bit slower.
But I would say in the last few years we have seen things transfer and
adopt from other industries within the construction, with ferries and, rapidness.
Some of the emerging technology that we're already seeing in use in construction,
virtual reality.
The ability for
end users to interface with the model, understand, look, touch and feel.
Actually feel with haptic feedback, the way it's going to be in their environment.
Maybe it's a nurse, or doctor who's going into an operating room and
feeling what left handed, right handedness feels like within the space.
Or from a construction user perspective, really engaging with the design,
the overall building ,the way it is spaced out, from a site logistics.
From the flow of workforce and materials,
to the overall delivery of the construction in the field.
Virtual reality, augmented reality, gives us the opportunity to see the building
in new and unique ways, that aren't just confined to the screen itself.
Yes we can see them in 3D, but
now we can let our brains effectively work within the space that we're designing.
The second emerging technology already very well used in construction
is RF-ID tagging radio frequency ID, whether it's active or passive.
The ability for the things we're installing to talk back to us.
Tell us a little bit from a cost estimating and control perspective.
Their status of installation, where they are at in the overall process, or
simply from a tagging perspective, for the long term maintenance of a building.
Understanding the work that's been done on it from a maintenance perspective
in the overall life cycle costing.
Perhaps the next step, of even smarter things talking to one another,
is really around this internet of things.
The ability for pieces of specific equipment controls, the facility itself,
the lighting, the occupational state of a building, to really all interconnect and
make the building live with the overall intended use.
All of these things are evolving right now to the point where we can use them,
we can bring in some of these things to the models that we're using right now.
And/or focus on the specific flows that we use operationally to deliver
construction to tell us certain things about the status along
the way of the processes that we enable.
Back in 2004, National Institute of Standards and Technology did a report
on the cost analysis of inadequate interoperability in US capital facilities
and concluded that the construction industry in the United States wastes close
to 1.5 billion annually, just in having the inability to have its systems talk.
That was back in 2004.
You've seen through this presentation, though some of the connections that
are made are manual, that things have evolved from 2004.
Part of what gets me excited about the industry is where we're at right now and
where things are heading.
The ability to take disparate databases from a financial management system,
5D estimating or modelling software system.
And really connect the two together in order to make meaningful representations
of the data.
Make decisions, really understand the current state of the process
project delivery, connecting with the schedule, etc.
We are seeing a new world of really connecting those pieces and talking.
I participated last week in, this is last week being October 2016,
in Lean Construction Institutes Congress.
And at the congress I happened to see a presentation from individuals at
Boulder Associates, a architectural engineering firm that works in
hospital and other large commercial projects.
And they did a presentation where they had taken, using Tableau Software,
which is just a software that can bring together disparate databases and
present from a dashboard perspective.
That intended use wasn't necessarily design, but they did a whole presentation
on how they were able to focus on the workflow from a design perspective,
in this case particularly door hardware.
And really cycle through the process from a designer's viewpoint.
Stitch in the Revit database from the Revit API, bring in relevant information
from product submittal data from PDFs, and create door schedules.
And really streamline and
take error-proofing into the execution of the process.
That to me is just a perfect example of taking the parts that we already have and
interconnecting them in the right way.
What you see on the screen now is just further example from their firm's use of
on an IPD project of bringing the cost control part into it.
Using that same background, that same framework, the Revit model, and
the cost forecasting from the individual companies participating in a project.
And really bringing together, in real time, in a meaningful way,
a visual control of where the project is heading from a resource and
labor utilization perspective.
It gives us the opportunity to connect pieces of information that otherwise
were not possible to be connected without a lot of effort from a human counting, and
summarizing, and bringing together standpoint.
There's opportunities now.
So in summary, we talked about 5D estimating systems in general.
I gave you the very specific example of mechanical trade,
can be extended through other pieces of software, and
really understood from an estimating system perspective.
It's about the items, and how the system tells the items to come together,
that creates the efficiency for estimators, as well as,
the ability to take the software, and create replicatable components.
We saw some of the estimating in action, gave you a little bit of a feel for
what it's like to estimate in that environment.
Really just tracing off systems, copying similar systems, and
off setting them within the overall take off.
We talked about workflows.
The ability to really streamline your overall business when you're all tied to
the same database.
And really look through the workflow opportunities and
the hand-offs between different departments within the organization.
And really utilizing the data overall to give feedback into the system itself
and understand the delivery model.
We talked a little bit about implementation.
Some of the key considerations, if you are to embark on a journey of
implementing 5D estimating within your company.
Many different ways accomplish that task.
Just some good, sound, basic principles from a project management perspective.
And then next steps,
where do we see this going overall from an industry perspective?
At this point, through the Coursera and Columbia University program,
can obviously submit your questions.
If there's further information that somebody viewing this presentation
wants to know, please don't hesitate.
This information is forever evolving and
we're all learning as an industry together.
Furthermore a couple of thank yous.
As I mentioned before, I don't deliver this presentation solo.
There's a whole bunch of people who help bring that together, and
specifically I'd like to thank these individuals.
Guy Trapeni, who's our director of estimating.
Someone who I mentioned in the slide before, really knows the truth about
what it takes to get a full and complete estimate put together.
Bob Miele who happens to be a retired individual from the organization
with 30 plus years of experience in the construction industry.
And helped really, me personally,
from a coding and scripting perspective to make sense of the data we're using.
Richard Davis, you see those quick, acting, take off videos.
Nobody is faster than Richard, is our national database administrator.
Mike Tran and Steve Norris from southern California,
individuals who are really pushing the envelope.
Those lidar screen shots that you saw there are individuals
in southern California really working with that new technology and finding new and
unique ways to use them.
And then finally, Chris Johnson from CGHVAC,
someone that we used that as I mentioned before,
that really understood the backend of the database at the time we were implementing.
And how to get the software to do the things that we were thinking in our mind
from an estimating and operational perspective.
Again, it takes a village to raise a baby, this particular one takes a lot of effort.
And wanted to recognize those individuals, thank you.
