A design may look good in CAD, but often a proof of concept is needed.

Why Us?

Most engineers have neglected classical hand calculations and stress flow analysis in favor of the seemingly faster FEA process. True, FEA seems faster, but only if you designed it right to begin with. That never happens. Besides, FEA only shows you the hot spots, it cannot show you the solution.

Instead, using hand calculations as the primary design tool, combined with basic stress flow analysis, can eliminate the need for FEA in many cases. We still use FEA and are quite competent with it. However, we only use it as a check; thus saving time in the design process.

Why Failure is Essential to Success

Recently, I was teaching a class of how life is like a pendulum where one side is failure and the other side is success. Most people live their life right in the middle with little to no movement on the pendulum. It’s comfortable there. It is impossible to enjoy great success without great failure as well.

Will I Ever Be Charged More on a Fixed Cost Project?

No!

The only exception would be if the scope changed.  In that case, a new proposal will be provided for the additional work.  Depending on the project, a portion of the existing project may be credited on the new proposal.

Why Fixed Costs?

At Rasmussen Designs, we quote projects at fixed costs for your
benefit. Let’s face it, projects done on a time and materials budget
often end poorly when hours are running high. The desire to end the
project quickly grows and sometimes the parties never speak again. If
you have ever said to a contractor, “We’ll take care of it from here”
then you know exactly what I mean.

The main issues with time and material projects are

  • Budget Overrun – In many projects, the end
    can’t be seen from the beginning so projects are done on a Time & Materials (T & M)
    basis. Complications from the real world kick in and the hours start
    mounting. It’s only natural.
  • Lack of project scope
    – When a consultant is getting paid by the hour, the natural tendency
    is not to care about total project cost or the end goal. We will do
    what you ask us to. This always leads to budget overrun.
  • More Extravagant Solutions Proposed
    – If your project is done on T & M, the solutions will be larger
    and more costly than you desire simply because the contractor will need
    more time to implement the solution.
  • Lack of Innovation – When your contractor is being paid by the hour, there is no incentive to automate tasks or find creative solutions.
  • Hesitation in making additional contact
    – Let’s face it, we often hold back or hesitate before sending an email
    or calling because we are afraid of the bill that follows.

None of these lead to a healthy working relationship. Let’s see how fixed costs change this working dynamic.

Budget overrun is eliminated because the work in the scope of the
project is a fixed cost. Whether the project takes us 20 hours or 2000
you pay the same amount. Undercharging is our problem, not yours.

In order to give an accurate bid, we will need to have a well defined
project scope. A well defined scope forces both parties to talk about
the end goals, project values and outcomes desired. Having these well
defined at the start of a project always leads to client satisfaction.
This also prevents overly extravagant proposals and replaces them with common sense solutions.

Fixed costs promote a partnership between the contractor and client. With a well defined scope and cost, a level of trust
develops between the parties because even if the project takes twice as
many hours to complete, it will cost the same. There will not be
tension if you believe that we are not as efficient as we should be and
think that we are “milking the clock.”

Finally, additional phone and email contact will be part of the
contract. We welcome you to share your thoughts and concerns about the
project without hesitation.

 

How Do You Do Fixed Costs on Unclear Projects?

In many projects, I have looked back and said, “I wouldn’t imagine that the solution would look like this.” It is impossible to quote a fixed cost for the entire project when you can’t see what the end looks like from the beginning. Unfortunately, many projects switch to time and materials at this point.

But, let’s back up for a minute. We can definitely break up a project into sections that we could see the end from the beginning and quote each of those as fixed cost projects. For example, the first stage of a project could be simply to come up with 3 or 4 concepts that could solve the problem at hand. From there we could decide on one and develop if further.

I have found that most projects can be broken into the following stages; concepting, preliminary design, detailed design, final design and implementation. In each stage a clear scope and goal can be set and a fixed cost can be quoted.  In each stage, it can be addressed if Rasmussen Designs is still the best candidate for the project.  Often we are only needed for a few of the stages and will point you in the right direction.

What Software Do You Use?

For 3D CAD we use Solidworks and can use your version if it is still supported.

AutoCAD is used for 2D drawings of electrical and hydraulic schematics

MathCAD and MS Excel are used for hand calculations.

FEA is done with Solidworks Linear Simulation and is saved in the eDrawings format.  A free reader is available online
