10. Your engineering firm has been contracted to solve a sewer Leak in a clay tile pipe next to the lucky lady horse Barn.  Your recommendation is to remove the existing Sewer and replace the entire 300-ft long section with a new 6-in.diameter pvcpipe.  Your design requires a 5-ft wide by 6.7 ft deep excavation with vertical side walls(see fig. 1 in Moodle).

A. You call dr. Mahar for his advise and he gives you the following list of activities and the activity sequence:

-          Replace asphalt                           - place/compact granular

                                                                       base course

-          Layout sewer line                        - excavate asphalt and     

Soil and remove

                                                                            damage pipe

-          Compact soil beneath                - place new 6 in. Pvc pipe

   new pvc pipe

-          Backfill and compact                - pavement markings

    trench

B. The activity sequence for replacing the damagedsewer
