Players want to repair and restore an old giant outpost

[warren Burgess]

Greetings all
Ok in the exploration campaign I am running my players have found an ancient giant outpost an would like to repair and restore it for smaller folk use (read human) as a forward base of operations that extends their range.
where would I find the mechanic/costs for this endever or do I need to pullout my old 3.5 and 2nd ed guilds to chop it out?
The place is 2 stories each level has a 25ft ceiling and is roughly 100ft x 120ft mason work that is structurally unstable but could possible be repaired (the player have a PC with Profession engineering)
I know that they will have the best chance with a person that has craft stone work or profession mason.
But the cost and the DC I can not locate so any suggestions or info would help
Thank you

At this point, I would just say use your DM hammer and make an executive decision.

X Amount for stone(unless they cut it themselves)
X Amount/day for manual laborers to haul it to the site
X Amount for other materials(scaffolding, etc)

Obviously, if the PCs pitch in with the manual labor this will reduce costs, and so will it if there's a mage using spells to make life easier. Enlarge, Bull's Strength, Unseen Servant, etc.

My party is actually doing something very similar to this in my game.

I'd say wing it. You're the DM. What you say goes, but make it reasonable, and the players will bite.

You're the DM, make up some reasonable numbers and go with it.

Give em unreasonable numbers that can be lowered by doing a variety of reasonable things. Make it fun. Have them enlist a dispossessed clan of dwarves to help them, in return for their promise to help the dwarves locate their lost-to-time ancestral home. Perhaps a wizard (a studier, not an adventurer) they rescue lives their a while and helps out magically to rebuild and enhance the place while they are away. Maybe they can get reduced timber costs by doing a quest for a nearby village in the forest.

Some diplomacy checks with the nearest towns and cities to get trade routes or caravans to head out there with workers could also be a fun skill-based thing the PCs could do to lower prices.

I'd go with stuff along those lines. It'll mean more to them than just dropping some gold.

Suggest their bard to get a lyre of building and save on the manpower ;D

[RedPorcupine]

The party doesn´t include a druid per chance ? Greatest building-masters and interior decoraters, with wood-shape, soften earth and stone, stone shape?
Have the consider wooden-ceilings/platforms to increase living space.
