Create a linear schedule for the following $12,000$ foot$-$long Light Rail project, with $6$

platforms, and indicate the total project duration. $(5$ points$)$

Sequence of tasks:

Utility work, done in $4$ segments $($or "blocks"$)$ of $3,000$ feet each, using $2$ separate

work crews. $2$ months duration per segment

Roadway work, done in $6$ segments of $2,000$ feet each, using only $1$ crew. $1$ month per

segment

Platforms, $6$ total located at stations $00+00,20+50,50+00,70+20,90+00,$ and

$120+00.1-$month duration per platform

Signals, done in $6$ segments of $2,000$ feet each. $1$ month per segment

Streetlights, $1,500$ feet per month. Must be done linearly from $00+00$ to $120+00$

Overhead Contact Systems $($OCS$),2,500$ feet per month. It must be done linearly from

$00+00$ to $120+00.$ It must keep a $\frac{1}{2}$ month buffer with Streetlights.
