Quality Management – Cost and Time Management
Initial Cost of Materials & Equipment Labor Cost Long Term Cost Time Management
Quality Management – Cost and Time Management
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.
Quality Management – Cost and Time Management
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
Quality Management – Cost and Time Management
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
Quality Management – Cost and Time Management
Fabrication time: shop vs. site Erection time: prefabricated items go up
faster Construction Sequence: contractor
controlled, but design has influence on sequence– Partitions that extend to the deck limit the ceiling
installation till after the walls are finished
Project Code & Zoning Analysis
Working with the IBC Working with a Zoning Ordinance
Working with the IBC
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
Working with the IBC
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.

300 people w/ 2 means of egress; 150 people per egress
150x0.2=30” wide corridor…or..
If you design a 5’ wide stairway it can hold 60/0.3=200 persons get bonus w/ sprinkler 60/0.2=300 persons
Working with a Zoning Ordinance
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.
Working with a Zoning Ordinance - 1
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
Working with a Zoning Ordinance - 2
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
Working with a Zoning Ordinance - 3
Obtain the zoning map that outlines the various zones in your municipality and locate your project address on the map.
Working with a Zoning Ordinance - 4
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!
