R. S. Means (Reed Construction Data) has a book called
Means Residential Square Foot Costs
It has economy average custom and luxury models - 1, 1½, 2, 2½, 3, bilevel and trilevel. You then have main building, and wing or ell sections, local modifiers, 1,2, or 3 family; detached, row or semi detached; and exterior wall modification
You can calculate insurable cost or replacement cost. It is illustrated. it has specs for each level, and breaks down the cost per SF.
But the bulk of the book is devoted to break down of individual features and that can be used to estimate repairs, etc. It also includes pools, fencing, driveway costs, etc.
It has location factors. It lacks a residual table or total life estimates, which I believe NBC has & NBC has commercial buildings and ag buildings. List price is $39.95. In my opinion, Means is a little more detailed than NBC and is nearly, if not, as detailed as M & S. In fact, the assemblies section is more detailed than M & S. Buy from Amazon and have it next week. I think Barnes and Noble may keep it as well.
I created a table in Word Perfect for both NBC and Means which I can input the costs and calculate a total per SF cost. I also have a 3 sales land grid which I put the table with and an introductory section which comprises my entire Cost approach in Narrative. I created it as a template and can usually knock one out if I have the three land sales in front of me in about 15 minutes.
I find Means more often calculates a unit value that resembles local builders costs derived from the market..especially for newer houses in the 1,200 - 2,400 SF range and average-custom quality. "Luxury" is just too variable...ditto for M & S high quality home estimates, too.
There is also a program which you can buy for like $99 PLUS the CD of the book (varies but $299 is about the max) for creating estimates via their program. The program will run the SF book, but also can be used for other Means titles, including the electrical contractors cost book, commercial cost books, etc. There are also on line updates you can download quarterly. They also list 27 software vendors who use Means Cost data in their calculator programs.
how would the Craftsman book hold up in court if you had to defend it?
Reed Construction is worldwide and has been around since 1942. Robert Snow Means established the cost service. They mention him in the past tense so I assume he is dead. I was told by a casualty appraiser that they relied upon their books exclusively and that part of the data used by M & S comes from Reed. NBC polls about 120 companies plus other sources of data. M & S may be the largest but they are not the only provider. Boeckh was older than M & S until they sold out to M & S. Boeckh was used by the insurance biz probably more than was M & S, which was assessor and appraisers. M & S has ruined Boeckh, which had the very best software for Residential estimating that I ever used.
