Alright. Time to get shit done.
Carpenters, you now have tools. You may cheer. So let's work on a lot of things for you, because there's a lot of things you're useful for.
First off, you're going to start making boats. Pontoon boats, in fact, for a pontoon bridge. Like broader, shallower canoes, made of thick planks, and upturned at either end, but relatively flat side to side. We'll use rope to keep them together at first, with several tied to big boulders or trees on either side of the river to keep them from floating out to sea. Later, we'll embed them in the ground with wooden constructions, once the project is mostly finished and both banks are connected. They should be pretty tightly packed and held together, with strong knots from whoever can do them, to be good and sturdy. Over them now, and this will all probably be done in sections going across the river, rather than all at once, over them will go balks, thin strips of wood laid over the boats, maybe 2-3 cm by 1-2 cm, and at least as long as each boat is wide(make them similar in size, guys, please?). Over these will go cross planks, planks laid perpendicularly to one another, thinly, to form a smooth surface. With metal tools, getting some of the smiths to make some nails shouldn't be too hard, or we might get some from the trade. In addition to that, guard rails on either side, mostly to keep the planks on the bridge and not in the water(part of the reason the boats need to be upturned at either end, by the way). Later, we can use it to work on an even more permanent structure, and it should be strong enough to support anything we'll be dealing with, for now. Get the Lumberjacks and Avians and smiths to help you, if you can. Oh, and for fuck's sake, keep the goddamn bridge clean and clear! Don't let debris collect on it. You need to get someone to make sure it's clear, every day. Better if it's twice a day, unless you want to restart the whole thing when it goes floating into the ocean.
But this isn't all. We need planks. Not just timber; lumber. We need the wood to be processed so it can be used more efficiently. Oh, and agreeing to make a cot for people who help you should get you plenty of volunteers for all these tasks, as long as you don't screw their new bed up. So work on that. And also, we're goblins. We need a true Goblin Hall. You can at least get people to help you lay out the groundwork for that, getting stones and whatnot for a foundation. Plan for at least 50 goblins to live in it. Preferably more, with food prep rooms, a dining hall, a place for a Shaman, a still(which will be able to be expanded), washing rooms(you won't be dirtier than the elves, damnit, even if noone can compete with Nekos), and preferably a basement storage area, though that may need to be a separate thing and will need miner help in all likelihood. Plus, it's not important yet. Also, a small barracks, separate, room for 20 plus, with armor and weapon storage, and a dining hall of it's own, with a smaller food prep area, a washing area, and a training area. These buildings are currently, however of low priority. Just get the groundwork set, area marked off, land cleared of obstacles, etc.
Still not done, though. Take some of our logs, make them into supports for those mine tunnels. Places to put torches on them(and a way so they don't catch on fire) would be good. Long, hollow tubes(yeah, I know it's hard to hollow them out if they're long, maybe cut out a section along the side, hollow it out, and attach it back on, 'kay? Glue/adhesive has been around for thousands of years. Not too hard to make it) can be used as air shafts for the miners(so they should be 3-4 inches around, at least). If we need to, we can attach pumps to them later, to get air pumping better(it could run off the river water, even). Make sure they stick up out of the ground a good 3-4 feet; short enough for people to look inside and see if something's clogging it, tall enough so people won't(usually) be tripping over them, and tall enough that stuff won't fall in it(often).
One more thing. Work with the brewers, build that Still. People who help get to have alcohol. People who refuse to help have to wait. That simple.
Ranchers, begin taming/domesticating the horse. It's feral, hostile, and we don't yet have the ability to selectively breed them, but you can certainly try. I really hope I don't have to explain how...
Brewers, help the carpenters with the still, since you're gonna have specifications. That way we can actually make a half-decent brew...
Finally, Gatherers, help everyone around. Gather some root vegetables and herbs out in the wilderness if you can, but don't pass up good opportunities.
I present the idea of Wooden Armor. Not 'bark', but hardwood, carved and shaped to fit a person, held together by leather straps, with thick, tough wooden 'scales' over joints and such. Don't use crappy wood, and preferably use the part of a tree for which the grain suits the part in question, so a lucky blow can't just split the wood in two. Better than nothing. Also, multiple shield types; Tower shield, as tall or taller than the wielder and layered with strips of hardened leather, thick wood; kite shield, some 2/3 as tall as the user or less, vaguely kite shaped, and still covered in hardened leather, also thick wood. Round Shield, maybe half as tall as the user or less, with a metal boss for the hand to grip it in(it's the protusion-y part; circular, metal, holly, blunt tip sometimes, with a handle in it), this time no leather, except for a leather strap to hang it around yourself. Finally, more weapon types. Poleaxe(Like a spear, but with an axe head up there too), pike(even longer spear! Yay! But not suited for charging. Great for stopping charges.), and...something else. I forget.
