A $20$ in$.$ square column $12ft$ high is to be concreted in $1hr$ at temperature of $60F.$ Use Tables and Design the formwork $($sheathing$,$ studs and clamps$)$ for ten or more uses, with $\frac{3}{4}-$in$.$ plywood sheathing braced by $24\text{'}$s of construction grade Douglas Fir$-$Larch used flat and clamped with metal "self$-$squaring" clamps. $(10$ points$)$

Use Tables and out spacing of supports for sheathing, joists, and stringers components of slab formwork using tables. The total dead and live load including the self weight of the slab acting on sheathing is $355$ psf$.$ Use $2$x$4$ S$4$S for joists and stringers. Use #$2$ Douglas Fir Larch species. Use $\frac{3}{4}$ inch plywood for sheathing. Assume all supports as continuous over four or more supports. Assume grains parallel to span. Assume forms are not reused. $(10$ points$)$

Use the tables to determine spacing of wall form members, assuming continuing reuse of the forms and No$.2$ grade Douglas Fir$-$Larch or equal lumber, with sheathing of Plyform class I plywood. Design a $10ft$ high wall form for a maximum lateral pressure of $600psf,$ assuming no reduction of pressure near the top of the form. $(10$ points$)$

A four story building shown below is formed using one level of shoring and two levels of reshoring system. The thickness of each floor or slab is $10in.$ The slab is designed for its self weight, $30$ psf superimposed dead load, and $50$ psf live load. During the construction cycle, a new slab imposes its self weight, $10$ psf formwork load, and the $50psf$ of construction load. Use unit weight of concrete as $150pcf.$ Assume rate of pour as one story per week $(5$ days$)$ at temperature of $60F.$ Assume that slab$-4$ is just poured.

A$)$ Prepare a table to compare the maximum slab load with equal distribution of construction load and slab load capacity when the slab$-4$ is poured $(2\mathrm{.}5$ points$).$

B$)$ Identify which slab and under what stage of construction will have the maximum load and calculate the magnitude of that load $(2\mathrm{.}5$ points$).$

C$)$ Calculate the magnitude of maximum load acting on shores $(2\mathrm{.}5$ points$).$

D$)$ Also check whether the one level of shoring and two levels of reshoring system work or not $(2\mathrm{.}5$ points$).$
