“It Costs What?!”
As with most things the final decision come down to pricing. How much does a product or service cost and as the buyer of those goods or services do I perceive that amount of value? If I see the value, I transact the deal. If I do not see the value, I find an alternative solution or do not do anything at all.
The Fixed Cost:
Determining the Cost of On-Location Scanning:
At TruePoint Laser Scanning, pricing the actual laser scanning service is fairly straightforward – we charge a daily rate. And since we have industry-proven experience in determining how many scans can be accomplished in a set period of time, we feel confident in quoting an accurate price.
The Variable Cost: Determining the Cost of Deliverables:
However, when determining the deliverables section of the quote it gets a bit more challenging. Often clients say “we want a model of everything” and since the thought process is that “scanning captures everything” the client would like “everything” in the model.
Defining “Everything” :
However, like the humor in this newsletter, what we often find is that people have different meanings of “everything”.
- Some clients quite literally mean that if it is in the scan data they want it in the model.
- Other clients say they want “everything”, but really just mean that they want the dimensions of the space.
- And most often times the real desire is somewhere in between – “well, we actually just want certain piping, structure, and these key areas of interest”.
Now Down to Brass Tacks:
Our job as the scanning provider is to listen to our client, ask the right questions and decipher what the client is interested in and define it into a scope of work. Having engineers and architects on staff with real world experience helps us understand what our clients really need and define the scope in order to determine right price.
The important thing is that we understand the scope so that we can make sure we are not providing too much, creating unnecessary costs, and certainly not too little and have a client be disappointed in the deliverables. Additionally, we can often suggest other workflows and deliverables to assist our clients in getting more benefit and value out of the data.
Finding the True Value:
Once we have the scan data, there are so many things that can be done with it! Often times, we can bring the most value to our clients that think of us as consultants or partners with an active role in their project.
Task: To create, as part of the overall engineering survey, an as-built of the interior and exterior of the entire building structure, which included 6 stories of parking garage, 2 floors of retail space and 8 levels of office space.
Challenge: The project changed hands during the development phase, and there were no existing drawings for the new construction management firm that was hired to complete the project. In addition, the project was in various stages of completion so the new CM needed to be able to verify and document the percentage of completion for all disciplines. Given the size and complexity of the project, field measurements would have been timely, incomplete and inaccurate.
According to The American Institute of Architects (AIA), change orders account for 3 to 5% of total construction costs. These costs are often equally distributed between the following:
1) Errors and omissions
2) Field conditions
3) Owner requests
For a $10,000,000 project, that could equate to $500,000 in additional costs, not to mention schedule delays and general frustration among the project's team members.
However, laser scanning can help minimize all three categories of change orders. Laser scanning gives the design team more information upfront, which allows design decisions to happen sooner and makes for a more complete set of bidding drawings. This, in turn, allows contractors to have confidence in their bids, to fully utilize BIM for virtual construction, and to prefabricate more of their products—all of which, in the end, allow contractors to meet critical path schedule dates, as well as limit both re-orders of materials and delays due to unforeseen field conditions.
1) Owners can reduce their costs and tighten their schedules. Furthermore, owners will then have better control over all categories of change orders, allowing for more prudent negotiations and discussions regarding the captured information.
2) Architects and engineers can make critical design decisions sooner and with more complete and accurate information. Additionally, they can creatively utilize the point cloud data directly for construction documents, minimizing their drawing or modeling hours. This, in turn, results in a reduction of both RFI’s and change orders related to field conditions, as well as a reduction in errors and omissions.
3) Contractors can streamline their construction process and prefabricate more materials off-site. This can result in reduced labor costs, fewer schedule delays, and the satisfaction of delivering a project on time and under budget.
