SUBJECT:
Summary of work performed on the CONCEPT computer code In an effort to improve upon the usefulness and accuracy of the CONCEPT code, the following modifications were made to CONTAC and CONCEPT:
1)
A descriptive title which is stored in each cost model consisting of up to 80 characters is now printed in the heading of each page of CONCEPT output.
2)
The D-array (detailed cost elements) has bean enlarged tohandle up to 400 separate accounts.
3)
Taxes that are directly proportional to craft labor (e.g.
social security, workmen's compensation, unemployment) are now implicitly included in the labor dollars presented in the estimate.
This is accomplished through t r. e use of the contractor's overhead burden factor (COB) which serves as a multiplier for all labor accounts.
COB should be input in the cost model as a decimal fraction less than one.
Also, any explicit craft labor taxes stored in the D-array should be removed.
4)
As a result of the changes in item 3), the case-specific overhead factor (COS) has been deleted.
Namelist changes can be made to COB to change overhead burden on a case-specific basis.
5)
In order to more explicitly account for the craft labor.-
in the construction services account (Acet. 91), the manhours in that account are now calculated and printed in the two digit summary.
The total craft ma nho ur s as well as the manhours per kilowatt printed include account 91 manhours.
This now requires that the implicit labor rate in account 31 be input in the XLR array of the cost model.
Also, the manhours in account 91 must be added to the total craft manhours in the model (MHT) and optionally to the MHP array (individual two-digit account manhours).

6)
As a result of including the account 91 craft labor manhours in the total craft manhours, the case-specific manhours j
per kilowatt input possible through namelist (AMAN) should reflect all craft labor manheurs rather than just direct craft labor manhours as stated in ORNL-5470.
I trust these changes are satisfactory.
Should you have any problems or questions, please call on me.
