Enter cost per lineal foot and wastage % for Stumps, Bearers, Joists and Boards to Calculate individual and Total Costs.
Lineal feet and cost are auto updated when the deck is re-calculated, with individual costs for stumps, bearers and joists displayed in each section.
Hit + and - buttons to open or close spacing, re-calculating the deck to find how different spacing options effect cost and materials.
After adjusting individual spacings (add or subtract stumps, bearer, joist etc), mouse over newly calculated 'Total Cost' results to see
previous cost and cost difference. You can instantly see how much extra it will cost to reduce spacings and add stumps, bearers, joists etc.
After entering lineal costs, hit the + and - buttons under the top diagram to re-calculate deck and total cost, and mouse over cost to see difference.
If your deck is slightly out of square (different widths), calculate results for both widths, and set out each end to suit.
If necessary, adjust number of deck boards to match in both calculations, and see if different board gaps at each end of deck are acceptable, compared to equal gaps and cutting the last board at an angle.
Use the widest dimensions for lineal quantities.
