I´d like the construction yard to be changed
into a more realistic ability.

Now you are CONSTRUCTING predefined DESIGNS.
It is more realistic to construct its components and then give the order to ASSEMBLE.

Space Yard Facilities will then be used for
constructing bridges, CQ, LF, Engines etc etc.
The ´surplus´ of one turns build would be stored
on the planet. (Ability 1 storage 2500kT).
Cargo facilities can enlarge the storagecapacity.

When you have made all components you construct (=assemble) the design. Assembling cost could be
an ability (10 % of the total constructioncost
of all items).

You will be able to produce more efficient but it
will also mean a better planning and transport
of builded items.

Yard Facility on ships can work with a storage ability (500 kT and rising when achieving a higher techlevel). If not sufficient you will have to use more ships !!
