Apologies for the very long reply time on this one. The base building section is in the process of being revamped, with additonal worked examples being provided in errata section section of the website.
Do the construction time bonuses (and additional costs) provided by such additional teams accumulate over the entire building or are these applied per hex only?
They accumulate across the entire building in the case of an isolated structure, or across a complex. Complexes will be slower to build, but optimize the times and costs through savings on roundings.
Example:
A 4-hex, 1-level heavy hangar is constructed with two additional hired professional teams per hex, i.e. 8 total. The construction time required before bonuses applied is 12 days. No structural modifiers or additional equipment apply.
- Is the construction time bonus in this case calculated per hex (12 days * 0.8^2 = 8 days rounded up) or for the entire building (12 days * 0.8^8 = 3 days rounded up) ?
The calculation process has now changed to make it simpler. In this case using 8 trained crews across 4 hexes gives a build time of 9 days. (12 / squareroot [8*1/4] = 8.5, which rounds up to 9 days).
- If the bonus is calculated per hex are equal numbers (i.e. equal outfit of additional teams/vehicles/etc) required for construction?
That was one of the problems that needed addressing. The new method takes into account the number of hexes and just averages out all the crews across the structure. You could have 2 trained crews in 1 hex and and IndustrialMech in another, but the amount of work is assumed to be the same per hex.
- The same questions apply for summing up the cost penalty (+11% on each hex for two teams each or +68% for the entire building for eight teams total).
Costs have also now changed. In the case of this example, each trained crews costs 5,000 C-bills per week. The build process takes 2 weeks (9 days / 7 = 1.3, rounds up to 2 weeks). So your Total Construction Cost will be 80,000 C-bills (5,000 * 8 * 2 = 80,000 C-bills).
