Building codes and regulations provide minimum standards for building construction and safety. They address requirements for materials, building systems, fire resistance, means of egress, occupancy loads and more. Various codes apply to different aspects of construction, such as the International Building Code, International Residential Code, and National Fire Protection Association codes. Buildings are also subject to zoning ordinances and legal requirements regarding accessibility and worker safety. It is the responsibility of architects and designers to understand and comply with all applicable codes and regulations to ensure building safety.

- Introduction to purpose for building
- Suitability: PRIMARY FOCUS OF THIS COURSE SUITABLE FOR THE USE INTENDED EXAMPLES: CARRY THE LOADS, PROVIDE THE REQUIRED FUCTION, SUITABLE WITH ENVIRONMENT Availability; CAN YOU OBTAIN IT? IN THE TIME NEEDED? Cost; MOST ALWAYS A “PRIME” CONSIDERATION OFTEN THE PRIMARY RESTRAINT Appearance; DESIGN (AND TASTE) CONSIDERATION, subjective ARCHITECT AND OWNER Preference; SUBJECTIVE CONSIDERATION - A/E & OWNER
- Building Performance Issues ITEMS SUCH AS FUNCTION, AESTHETICS DURABILITY, LIFE, expansion/contraction, heat flow “ STRUCTURAL” Design CONSIDERATIONS MAINTAINANCE MARKET ATTRACTING FIRE SAFETY, ETC. INITIAL COST, LIFE CYCLE COST Evaluated on Every Building CONFRONTED DURING DESIGN Involve “Trade-offs” - Time, Cost, Quality Construction Issues Deal with Actual Construction Relate to Means and Methods ITEMS SUCH AS: SAFETY, SCHEDULE, COST, QUALITY, OPTIMUM USE OF TRADES, WEATHER, ACTIVITY SEQUENCING, PRODUCTIVITY
- Contractual Arrangements; TRADITIONAL OAC?, DESIGN BUILD?, DBO?? A/E STILL INVOLVED - DEGREE OF INVOLVEM’T Designer/Architect TYP.-PRIMARY INVOLVEMENT/RESPONSIBILITY WITH INPUT FROM; Owner for suitability, appearance & preference AND Contractor on cost and availability AND SOMETIMES SUITABILITY WHY SHOULD A CONTRACTOR BE FAMILIAR WITH MATERIALS? HAVE KNOWLEDGE OF COST, AVAILABILITY, INSTALLATION REQUIRMENTS - TO BE AN EXPERT/SOMEONE WHO CAN ASSIST THE THE OWNER AND A/E
- EXPLAIN AIA 201 (CONTRACTUAL CONDITIONS) WHY IS CONTRACTOR RESPONSIBLE? (& NOT A/E, ETC) Most Knowledgeable, “controls” the site operations Method/means affects price, & time What the contractor should best know HOW OFTEN IS CONTRACTOR “ instructed otherwise ”? WHY HOW DO CONTRACTORS GET IN TROUBLE? USING “NON-APPROVED(SPEC.) MATERIALS NOT FOLLOWING MANUF. RECOMMENDATIONS EXAMPLES; WP CURING TIME, HOW TO AVOID PROBLEMS FOLLOW PROJECT SPECIFICATIONS, MANUFACTURERS INSTRUCTIONS/RECOMMENDATIOS
- MANY CODE REQUIREMENTS HAVE TO DO WITH “FIRE RATING” REQUIREMENTS Measured in Hours (or fraction thereof) Typically - Increased Fire Resistance results in Increased Construction Cost INCREASED RATING - GENERALLY INCREASED SAFETY, BUT ALSO INCREASED COST THEREFORE OFTEN BUILD YTO LOWEST ACCEPTABLE RATING. WHY??? OWNERS WANT TO BE UNSAFE??? NO, OWNERS WANT TO BE COMPETITIVE
- Full Scale Laboratory Tests MOCKUP, ACTUAL COMPONENTS TEST TO DESTRUCTION Identification of Components TABLES / STANDARDS PUBLISHED MUST BUILT TO / DUPLICATE TO MAINTAIN RATING American Society for Testing and Materials (ASTM) AS WITH A NUMBER OF CONSTRUCTION TESTS, ESTABLISHES TESTING STANDARDS
