22. What are shop drawings used for?
ANSWER: They are provided by equipment manufacturers to show details of the equipment for a specific job.
23. Outline the steps involved when creating a job estimate.
ANSWER: The main steps include preparing a material take-off, tabulating and pricing, and then summarizing the costs.
Material take-offs mean counting, measuring, and listing all the material, devices, and equipment required to
complete the installation and fulfill the contract. Pricing means assigning actual individual costs for each item,
as well as the labour required to install everything. Standard labour units are usually used, as established by
various organizations, based on specified working conditions. These units would be adjusted according to
actual job conditions. Summarizing the job estimate will also include other costs, such as overhead, tool and
equipment rentals, travel, and, of course, profit.
