During this operation, the car shall automatically by-pass registered hall calls. Such hall calls shall not be cancelled, but shall remain registered to be answered by a car in normal automatic operation.

8. Load Weighing – The load weighing by pass mode is initiated when the car is

loaded to the predetermined percentage of full capacity. When activated the car will ignore additional hall calls and deliver on board passengers to the registered floors. Upon release of passengers the elevator will automatically reset to normal service.

Materials

Specification and drawings outline the specific material to be installed on any project. On most AIA specifications the elevator section will be Section 14000, Conveying Systems.

Go to the outline of equipment for a quick reference as to the specific characteristics for the elevator specified. Then proceed to the specific details for the equipment to be supplied by going to the specific area of the specifications which will give the specific requirements for the equipment to be installed. For example, under “New Equipment”, Machine Room A.1 see the requirements for the new hoist motor and so on.

This study guide shows a specification for an elevator modernization. A modernization usually means certain equipment will be replaced while the remaining equipment will be reconditioned as new.

It is always recommended to compare the specifications with the appropriate sectional and plan view drawings of the elevator as shown on the accompanying layout drawings.

Labor

The number of hours for the job can be secured from construction supervisors and project managers. The labor rate can be obtained from your financial officer. The hourly rate may be broken down into hourly rate

(direct costs) and benefits, taxes, travel (indirect personnel costs). The labor costs in the Example of the Internal Estimate for the Apartment Building combines the total cost into one weekly rate.

Overhead/Miscellaneous Costs

This rate is determined by the financial officer for each job and considers different insurances, bid bond ( if required), tax rates specific to the local and job, shipping, fees, permits and a percentage of the company’s operational costs.

Markup

This rate is based on a percentage of the total estimated cost of the job and may vary based on the job. For example, a job for a long term customer or for a charity may be lower than for other customers. The rate may be higher for a job that is exceptionally challenging. The mark up for this Example Internal Estimate is 30%
