MPNH Floor Extension
Materials
From the list of materials provided previously, the number of units for each material was calculated using the conceptual design. The cost for materials was researched from at least three different sources per material, and the lowest cost was taken. Miscellaneous materials include all fasteners, nails, and connections. It is assumed that the cost of all electrical wiring and gas pipes is included in the specialty labour cost.
Personnel
On this project, the required personnel include a project manager who will also coordinate and supervise work, a structural consultant to ensure that all designs and construction is built to code and adequate for the loads, and labourers to carry out the work. There are also specialty labourers, who will be completing work such as electrical/gas lining, the installation of hardwood and the fireplace, and any other work that required specialized knowledge to be completed properly. Hours are based on eight-hour days, over the six weeks as proposed by our project schedule. The manager and consultant hours include additional time for any work prior to or after construction that is required (e.g. Coordination of labour, closing of project).
The assumed average wages for each type of personnel are listed below:
Equipment
Equipment includes all tools required to carry out construction of the project.
RS Means Method
The cost of the proposed floor extension project was also analyzed using the RS Means Method. All data used is from tables RK1010-050 for a community center and ENR’s Building Cost Index History. The proposed area of the design floor is approximately 482 square feet, which translates into a size factor of 0.05, taking into account the typical size for community centers of 9400 square feet. Using this size factor and corresponding cost multiplier of 1.1, the base unit cost of $134/ square foot was adjusted to $147.40 / square foot. The total cost of the project could then be adjusted for time, as the data tables used are from 2006.
