When shared work changes the consequences

The sixteen rows above use their declared additive costs and whole-work times. They do not establish whether a different work arrangement could share a mobilization, require extra temporary service or change a later commitment. EAM.10’s separate P+Q/Z case shows why that question matters: one qualified shared mobilization makes the joint solution cost 3.8 against the alternative’s 3.9, while two required visits make it cost 4.0.

For a proposed CityWater arrangement, EAM.11 must establish its actual windows and whole work, and EAM.6 its service conditions. EAM.10 then reconstructs that combination’s consequences; FIN.9 supplies the financial return if joint cash or dated funding must be developed. Recompute the affected rows rather than applying a discount to all sixteen. If the change also affects demand, recovery or a continuing policy, return that premise to EAM.4, EAM.6 or EAM.8. The existing capital, time and D-qualification branches remain valid on their stated premises.
