Costs of project development need to be calculated

The customer asks for a calculation for the development of the PPRK, everything has already been developed, passed, signed the act, and he put forward this to me. I've never seen this before.

It is necessary to calculate the costs of developing a project for the production of works by cranes of the PPRC for the installation of equipment.

Project parameters:
Number of cranes: 1;
Composition:
- text part with calculations - 70 sheets;
- sculpting plan - 4 sheets;
Standards of working time of specialists
- 6 days x 3 persons;
Departure to the facility:
- 500 km one way and back;
Printout:
- 70 sheets A4 x 4 copies;
- 4 sheets A3 x 4 copies;
A CD with all this information recorded.

The price that should be indicated later.

I ask for help from experts in the estimate, economists and others.

In my understanding, this can be one of the following: an estimate with real prices for the development of such documentation, namely organizational and technological; calculation of the time spent on its development (in hours x price per hour + the cost of paper + the cost of printing + the cost of a CD-ROM recording + other costs); costing at some other prices (only in force to the Customer not to blush) + other costs; time standards for the development of such documentation + other costs; to pull out of overhead costs for CMP (as it seems to me they sit there, if possible).

Dear experts in the field of calculation and estimates, I am waiting for your suggestions.

I hope for mutually beneficial cooperation on this project and promising in my other projects (CMP and PIR).
