I am renovating my pool area and I might have a dispute on how the landscaper has screwed the hardwood to the feature wall and also the customer made seat they are doing.
Everyone I have spoken to after the event has said to avoid warping and cupping two screws should be used. As per the picture the landscaper has only used one and after only two weeks (they haven’t finished the job yet due to Xmas) some boards already have visible cupping.
When I questioned the landscaper why he only used one when I had received advice that two is standard he said that Hardwood under 100 ml only needs one screw.
Does anyone know if there are any standards for how many screws are required for hardwood. Our boards are 90 ml. I want to be able to have a reasonable discussion with him. He as suggested he could do more screws but having 3 screws on a 90ml board is overkill and my preference would be for him to start again and build to standards required.

The link below pertains to building decks.
Section 1.5.2 details fixing with nails and AS specify 2 nails per board per joist.
Section 1.5.4 talks about screws and states that the same principles should be followed.
Your issue may be that your not dealing with a deck but screens and the landscaper may try and use this as an out.
Simply put, it's very poor construction and no decent chippy would ever think of fixing of decking, screens or seating like that. You always use 2 screws. The board's will cup and look horrible in a very short amount of time. They haven't even countersunk the screw heads flush with the board.
