Question $5$: $(10\%)$

The arrow network shown below is from a multi$-$complex residential project. Each complex

is comprised of four buildings.

Each building has the following activities:

Excavation. $(4$ days$)$

Form and Pour Foundations and Slab. $(14$ days$)$

Frame Building. $(16$ days$)$

Brickwork.

The project manager needs to plan the start date of the brickwork activity. The Brickwork

activity requires $96$ WH for each building, and the project manager is planning to use a

brickwork crew working $24$ WH per day $(3-$person crew $*8$ hours$/$day$).$

For one complex only $($i$.$e$.4$ buildings$),$ determine, using the Linear Scheduling Method, an

appropriate start time for the brickwork activity to enable it to continue without interruption.
