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!
