$[20$ points$]$ You have been assigned as a staff geotechnical engineer for a project described below. The site is approximately $2\mathrm{.}5$ acres in size. Currently, the site is being used as a parking lot. The planned new development for the site will add $6ft$ of fill $($SP or SM$)$ to the top of the site $($i$.$e$.,$ from the top of existing pavement$).$ The existing pavement and base course material will be removed and replaced with this fill. The unit weight for this material, when properly compacted to $98\%$ of ASTM D$1557,$ will be $117$ pcf$.$

You have been provided with the following soil information:

Boring B$-1($see Figure $7\mathrm{.}3).$

$1$D Consolidation Test Results for the CL layer from a UD Sample taken at a depth of $17\mathrm{.}5ft($see Figure $7\mathrm{.}1).$

ID Consolidation Test Results for the CL Layer from a UD Sample taken at a depth of $37\mathrm{.}5ft($see Figure $7\mathrm{.}2).$

Soil Unit Weights summarized in Wible $5.$

Calculate the total consolidation settlement in the CL layers due to the addition of the $6ft$ of fill.

Table $5.$ Summary of Soil Unit Weights from Boring B$-1.$
