of the museum shown in Figure 13.18. Slope indications would also be shown along swales and where steep cut and fill slopes occur. Technical sections would also be provided where the designer wishes to ensure that the contractor understands the grading design intent for subtle or critical earth forms and slope changes.
Construction Sequence for a Bus Shelter The contractor lays out the construction area using the staking or layout plan included in the construction document packaged prepared by the landscape architect. The staking plan is the basis for the contractor to establish the locations of all the design elements. The contractor may hire a land surveyor to locate the design elements following the staking plan or may do the work with in-house employees. After staking is completed, the contractor does rough grading then constructs the wood forms following the staking plan and grading plan. The forms contain the poured concrete and are positioned on the ground conforming to the elevations shown on the plan. The contractor sets the top of the forms following the spot elevations shown on the site-grading plan. Stakes are installed to secure the wood forms so they do not move or bow out when wet concrete is poured. The sequence followed in erecting the forms and setting the elevations can be seen in Figures 13.19-A through Figure 3.19-J. Figures 13.19-A and 13.19-B show the overall layout for a bus shelter next to a street. The center area of Figure 13.19-A is the location
