Equipment rental at BuildlT.
Build IT is a construction company specialized in public works, such as roads, bridges, pipelines, tunnels
and railroads. Within BuildlT, engineers working at a construction site (called site engineers) often need
equipment, such as a truck, an excavator, a bulldozer, a water pump, etc. BuildlT owns very little
equipment; instead, it rents most of its equipment from specialised suppliers.
The existing business process for renting equipment goes as follows. When site engineers need to rent
a piece of equipment, they fill in a form called "Equipment Rental Request" and send this request by
email to one of the clerks at the company's depot. The clerk at the depot receives the request and,
after consulting the catalogues of the equipment suppliers, selects the most cost-effective equipment
that complies with the request. Next, the clerk checks the availability of the selected equipment with
the supplier via phone or email. Sometimes the selected option is not available. In these cases, the
clerk has to select an alternative piece of equipment and check its availability with the corresponding
supplier.
After finding a suitable and available piece of equipment, the clerk adds the details of the selected
equipment to the rental request. Each rental request must be approved by a works engineer at the
depot. In some cases, the works engineer rejects the equipment rental request. Some rejections lead
to the cancellation of the request, i.e., no equipment is rented at all. Other rejections are resolved by
replacing the selected equipment with another equipment-such as a cheaper or more appropriate
piece of equipment for the job. In this latter case, the clerk needs to lodge another availability request.
When a works engineer approves a rental request, the clerk sends a confirmation to the supplier. This
confirmation includes a Purchase Order (PO) for renting the equipment. The PO is produced by
BuildlT's financial information system using information entered by the clerk. The clerk also records
the equipment rental in a spreadsheet that monitors all ongoing equipment rentals.
In the meantime, the site engineer may decide that the equipment is no longer needed. In this case,
the engineer asks the clerk to cancel the request for renting the equipment. The supplier delivers the
rented equipment to the construction site in due time. The site engineer then inspects the equipment.
If everything is in order, the site engineer accepts the engagement and the equipment is put into use.
