Decking advice please

[steveb21]

Hello all,

Not sure if this is the correct place to post this, please correct me if it needs to be moved.

I am planning to build a deck in line with my outdoor pool.

Deck size will be:

5.4m x 6.0m
17.7ft x 19.6ft

I can get hold of either 5.4m or 6.0m deck boards so i have a choice on which way i lay my deck, both options will be no waste/cutting of boards.

I am considering laying the deck boards vertically and using the 5.4m boards.

Plan is to dig footings for posts (under frost line)
Fill with concrete and attach a post bracket (in wet concrete or attach via bolts)
Lay beams (using 2 joists nailed together)
Install joists
Lay decking boards


Questions:
For an area 32.4m square how many footings should be required? I think i can get away with 3x3 = 9 , or should i do 4x4 = 12

Thinking of using a post bracket fitting on top of the footing and then attaching deck post. Is this a good method?

Did try to upload or link to pictures however i do not have permission to do so.

Thank you.

Personally I would have at least 4 rows or 4 that's 16 posts depending on joist size might be overkill but that's the way I roll.

I had thought about 16 as well however that does seem like overkill.

Think i might just got with 12.

4 Across the 6.0m (2.0m spacing )and 3 down the 5.4m (2.2m spacing).

A question of attaching beam/joist to post. Do you attach on the beam to each the side of the post? or rest it on top of the post via some sort of bracket? What is the preferred method here?
