Save your nerves save your time and the onset of gray hair. Give us the problem. We can handle it. This discipline should be employed early in the Architectural process, at least the design submittal stage. If the Design has costly bugs, they continue to exist after Construction.
Many projects go astray when the design is to complicated for construction costs.
Although our experience is with Architects who always use quantitative Estimates, we have found, unfortunately, most do not. Most use a square foot cost handbook to arrive at their projected costs. With a reliable estimate, one sees the problem areas quickly. Cursory, Value Engineering is often done through this task. This requires the above Estimate.
