Ubi - Car Servicing Pits

Being a mechanical servicing pit supplier is no easy when you only have the PDF plan of the existing building. In this order, the client require me to estimate the plan and plot according to his rough sketches. The supplier is required to maximize the usage of space within the yellow highlighted area. They also need to know how many cars can be parked when the servicing pit is full.

Below are some samples for viewing. Thanks!
