When originally conceived, the Harper government estimated the cost of building 15 warships would be in the range of $26 billion, but internal documents and published reports last fall suggested the price tag could go as high as $40 billion.
The art and science of estimating.
Announced estimate 26 BCAD at time of announcement.
IF this were a Concept or Feasibility determination according to AACE guidelines then it would be a Class 4 Estimate.
According to AACE rules then the 26 BCAD is allowed to vary between +30% and -15% and between +120% and -60%
Effectively that means that the actual cost of the project could come in somewhere between 26 BCAD - 60% (or 10 BCAD) and 26 BCAD + 120% (or 57 BCAD) and the estimator would have done his job in a suitably professional manner.
26 BCAD Class 4 means a project cost of 10 to 57 BCAD.
IF this were a Budget or Authorization determination according to AACE guidelines then it would be a Class 3 Estimate.
And, according to AACE rules then the 26 BCAD is allowed to vary between +20% and -10% and between +60% and -30%
Effectively that means that the actual cost of the project could come in somewhere between 26 BCAD - 30% (or 18 BCAD) and 26 BCAD + 60% (or 42 BCAD) and the estimator would have done his job in a suitably professional manner.
26 BCAD Class 3 Loose means a project cost of 18 to 42 BCAD
If the estimater were confident in his or her assumptions and was prepared to sign off on a tight estimate then the 26 BCAD project could be expected to cost somewhere between 23 BCAD and 32 BCAD.
26 BCAD Class 3 Tight means a project cost of 23 to 32 BCAD
Given the "up to 40 BCAD" expectation I believe it is likely that a loose Class 3 Budget Estimate or a tight Class 4 Feasibility Estimate was the basis for planning.
That, in my opinion, would not be unreasonable given that yard, ship, weapons fit and support packages were all known unknowns.
IF the government has moved to decide on a firm supply package, a known design that has previously been built, then they are effectively moving up to a Bid or Tender Estimate, or a Class 2 Estimate. Many of the known unknowns become known and quantifiable.
At that point the 26 BCAD project could come in between 25 BCAD and 29 BCAD (tight) or between 22 BCAD and 34 BCAD (loose).
26 BCAD Class 2 Tight means a project cost of 25 to 29 BCAD
26 BCAD Class 2 Loose means a project cost of 22 to 34 BCAD.
Normally this would mean the government could be more comfortable on making projections about the number of ships with the number of systems possible with a budget of 26 BCAD. If we assume that the intention was to build 16 hulls for 26 BCAD and the budget holds but costs rise to the equivalent of 34 BCAD then available 26 BCAD will only buy 12 ships with the intended capabilities.
More ships can be acquired if some or all of them have reduced capabilities.
None of this takes into account the timelapse between the original 26 BCAD estimate and the current realities or realities at time of construction.
Nor does it take into account the Canadian Conundrum that sees a 100 MCAD Svalbard become a 460 MCAD Harry de Wolf with broadly similar fits and capabilities. Fits and capabilities also broadly similar to the second hand Ice Ship that the RN bought second hand from Rieber of Norway in 2011 for about 400 MNOK or 63 MCAD - constructed in 2001. Or something in the same price range as a new Svalbard.

So when the press get ahold of a number like 26 BCAD and discover to their glee that the number could be higher, I does not demonstrate the malfeasance of the estimator or the incompetence of the client. It demonstrates the ignorance of the press.
A Feasibility Study is not a Budget.
A Budget is not a Contract.
