GRAVITY WALL. CANTILEVER WALL. COUNTERFORT WALL.
GRAVITY WALL RESISTS BY ITS OWN WEIGHT
CANTILEVER WALL RESISTS ITS OWN WEIGHT AND THE SOIL ON THE
HEEL AND BASE SLAB.
COUNTERFORT WALL ACT AS DIAGONAL BRACING
,CONCRETE DESIGN

AGGREGATE SHALL NOT BE LARGER THAN 1/3 OF THE SLAB THICKNESS
OR 3/4 OF THE MIN REBAR SPACING.
LIGHTING DESIGN:

DEPENDENT ON LUMINAIRES OF FIXTURES. BASED ON AMOUNT OF
UPWARD AND DOWNWARD LIGHT. DIRECT=90-100% DOWN.
SEMIDIRECT=60-90 DOWN. DIRECT-INDIRECT=EQUAL UP/DOWN LIGHT.
GENERAL DIFFUSE=40-60% DOWN. SEMI-INDIRECT=10-40% DOWN.
INDRECT=90-100% UP.
CONCRETE: PRECAST V. SITE

PRECAST IS HIGHER STRENGTH THAN 3000PSI. TYPE 3 (HIGH EARLY
STRENGTH) IS TYP USED IN P.C.C. LIMITED IN WIDTH TO ROADWAY SIZE.
BETTER CONTROL FOR P.C. THAN SITE

, DUCTWORK UNDER STRUCTURE. SPRINKLER PIPING AND PLUMBING
NEXT. RECESSED LIGHTS NEXT. THEN DEPTH OF CEILING. PLENUM CAN
ACT AS RETURN SPACE.
COMPONENTS:

PIPING CAN BE COPPER, STEEL, PLASTIC, OR BRASS. CONTAINS
PIPINGS/FITTINGS/VALVES/SPECIALIZED COMPONENTS. COPPER CAN
BE USED FOR UNDERGROUND SUPPLY AND MOST COMMON FOR
BUILDINGS, JOINED BY HEATING AND SOLDERING. STEEL CAN BE USED
WHERE WATER IS NOT CORROSIVE. MORE DIFFICULT TO ASSEMBLE B/C
OF SCREW FITTINGS. PLASTIC PIPE IS SUITABLE FOR SUPPLY BUT
RESTRICTED OFTEN BY CODE. PLASTIC ALSO EMITS SMOKE/TOXINS IF
ON FIRE

WET PIPE, DRY PIPE, PRE-ACTION, DELUGE. WET PIPE MOST COMMON,
KEPT FILLED. DRY PIPE USED FOR SUBJECT TO FREEZING FILLED WITH
NO2 AND FLOW WHEN ACTIVATED. PRE-ACTION SYSTEMS SIM TO DRY
PIPE BUT WATER ALLOWED IN BEFORE ACTION. DELUGE ACTIVATES ALL
HEADS IN AN AREA AT ONCE. DELUGE USED IN HIGH HAZARD AREAS.
SOUND TRANSMISSION

HIGH NRC=LOW STC. NRC IS HOW ABSORPTIVE. STC IS HOW WELL
SOUND IS BLOCKED. ABSORPTION COEFFICIENT IS DIRECTLY
