Just a couple of fixing and structural questions using the design method Stewie has advised, to whom can answer them. First of all, slight change of that I won't be digging holes for the posts as the surface is now a concrete slab. Will be using the Pryda bolt down post anchor stirrups and Ramset 10x100mm AnkaScrews. The first question begins here. 1. The slab is on a slight slope, so to make the posts level when sitting in the stirrups can I pack under one side of the stirrup on the concrete with either plastic window packers or cut up some joist hangers and then bolt down the stirrup so when I place the post in, it will be near enough level? or bolt the stirrup down with the fall of the sloped concrete then pack under the post in the stirrup? 2. Should I use 1 or 2 M10 Bolt, Nut, Washer to fix post to stirrup? (Or 1xM10 and 1x100mm Batten screw) 3. Should I use M10 bolts in only the 140x45 bearers and just nail and batten screw the 90x45 "upper bearer" to the face of the post? or bolt both? 4. Although the posts will be off the ground sitting in the stirrups, is it over kill to water proof the bottoms? Thanks in advance guys!

Maybe you should re-read the original post and all of the replies to get a jist of what's actually going on here. Then maybe you could help with the recent questions involved as you seem to be a person who would know. Cheers. Re: Advice Needed: Construction of Merbau Platform Steps 10Nov 18, 2015 9:11 am Use galv bolts for most of the post to bearer and the post to stirrup connections. Ant stuff ups or re-levelling required and it is easier to resolve than trying to pry out nails. A bit more up front costs but well worth it. You could dig the holes, assemble most of the frame and attach the stirrups before you pour the concrete. Just temporarily support everything and you shouldn't need any packing for anything. Waterproofing the bottom of the posts certainly wouldn't hurt.

However as I said, there's a slight change as I won't be digging holes or pouring any concrete as the surface is now a concrete slab. Going to use the Pryda bolt down post anchors, which only require AnkaScrews/Dyna Bolts. So still seeking some advice on question 1? And question 3 (are bolts required for 90x45 "upper bearer" if the 140 will already have them)? Thanks! Re: Advice Needed: Construction of Merbau Platform Steps 13Nov 20, 2015 8:12 pm Stewie D Yeah, get the stirrups as level as possible by any means. Plastic wedges are a good idea. I'd still bolt the upper bearer as well. Stewie Really appreciate your time and advice Stewie. Good on ya mate ??
