  • Initial Cost of Materials & Equipment

  • Labor Cost

  • Long Term Cost

  • Time Management


Initial Cost of Materials & Equipment: To control cost the architect considers

  • Initial Cost of Materials & Equipment: To control cost the architect considers

    • Initial cost
    • Installation cost
    • Long-term cost
  • Architects must specify the most appropriate products & materials for proper performance

  • Most products are available with various features or in various grades

    • e.g. wood grade – CMU types – concrete
  • Cost of assemblies vs. individual components

  • Cost based on product / material availability, project location, suppliers and general economic conditions.



Labor Cost

  • Labor Cost

    • +50% of construction cost = labor
    • Architects sometimes try to reduce the amount of on-site labor by specifying factory made assemblies
    • Field labor rates and productivity are union based
    • Factory conditions are better and productivity is higher
    • States set ‘prevailing wages’ to even the pay scale for union and non-union workers
    • Costs can be reduced by using repetitive materials and details


Long Term Cost (Operational Costs)

  • Long Term Cost (Operational Costs)

  • Long term costs are usually inversely proportional to short term costs e.g.

    • High efficiency HVAC has a high initial cost but saves money over time
  • Can be client-type driven:

    • Developer = short term owner vs. owner occupied school or government building
  • Maintenance Cost

  • Specifying appropriate products & materials effects maintenance costs

    • Buildings that serve large populations vs. residential buildings
    • Toilet partition types / accessible ceilings allow for maintenance


Fabrication time: shop vs. site

  • Fabrication time: shop vs. site

  • Erection time: prefabricated items go up faster

  • Construction Sequence: contractor controlled, but design has influence on sequence



Working with the IBC



New Jersey follows the International Building Code, New Jersey Edition

  • New Jersey follows the International Building Code, New Jersey Edition

  • Additionally, NJ has it’s own Administrative Code which contains the Uniform Construction Code (NJUCC)

  • NJ also has adopted other codes for plumbing, electrical, fuel gas and life safety



For this course we will outline steps for using the IBC NJ Edition

  • For this course we will outline steps for using the IBC NJ Edition

  • A good method is the following sequential format:

    • Use & Occupancy – Chapter 3
    • Construction Type – Chapter 6
    • Building Height & Size – Chapter 5
    • Fire Safety Requirements – Chapter 9
    • Means of Egress – Chapter 10
  • Other information may be required for more complex buildings.



































































Along with the building code, the zoning ordinance is absolutely necessary for project development.

  • Along with the building code, the zoning ordinance is absolutely necessary for project development.

  • Remember zoning is enforced by law, so violations are subject to penalties. Additionally, the owner/client will not be pleased with a building design that cannot be built, the client can seek damages for this error.



Obtain a current property survey from the client. Usually a survey is part of the package given to the owner when the property was purchased (closing documents).

  • Obtain a current property survey from the client. Usually a survey is part of the package given to the owner when the property was purchased (closing documents).

  • If a survey is not available, the owner should engage the services of a licensed surveyor to prepare a new one. The survey should show all meets and bounds as well as street dimensions and exact locations of all structures on the lot, utility locations

  • If your site is irregular with slopes and hills, request topographic data as well. This will help with the building design



Obtain the current zoning ordinance. You may be able to place a phone call to the zoning office and discuss your project.

  • Obtain the current zoning ordinance. You may be able to place a phone call to the zoning office and discuss your project.

  • If your project is simple, the zoning official might simply fax you the required pages.

  • Otherwise go the municipal building and discuss the project in person. You may have to purchase the ordinance, prices vary from $25 to $50 (or more), so ask first



Obtain the zoning map that outlines the various zones in your municipality and locate your project address on the map.

  • Obtain the zoning map that outlines the various zones in your municipality and locate your project address on the map.



Read the sections of the ordinance related to your project’s zone.

  • Read the sections of the ordinance related to your project’s zone.

  • Read all other appropriate sections of the ordinance that related to your project (i.e. off-street parking requirements, lighting, signage etc.). This takes time and careful reading!
