Determining the cost for scaffolding requires taking measurements, calculating the number of units and types of parts required to cover the height and the distance of the job, using this number of units times the rental costs, and adding the labour required for the installation and removal. Then, add any special requirements of the job, such as the costs for safety netting, rubbish chutes, traffic control, and any other special needs of the work site.
For each work area, the maximum height needed for structures is measured. Differences in height are noted. The length is measured. This includes having enough material to go around the corners of a building.
Once the measurements are known, then a bespoke design is made to fit the job site. A calculation is made to determine the number of units and the type of structure that will be sufficient for the job. This number of units is used for the cost calculations.
The estimated job time in days, weeks, or months is used to determine the rental rate per unit. This is multiplied by the number of scaffolding units needed. It is always a good idea to extend this time, by adding a little extra as a contingency factor, to accommodate any job delays that might occur.
To determine the total project cost for any type of temporary structure, an estimate of the labour costs to erect and remove the platform is added to the rental costs plus the costs of any special job requirements.
