- 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
