MOVING SOIL FROM THE FARM USING SCRAPER(S) THE FIRST THING TO DO IS SET UP A SCRAPER PROBLEM USE THE PROJECT REQUIREMENTS AS YOUR GIVENS: SCRAPER MODEL: SEE PROJ REA'TS ROLLING RESISTANCE SEE PROJ REQ'TS LOAD TIME: USE NORMAL 0.85 MIN @ 96% CAPACITY (P235) EFFICIENCY SEE PROJECT REQ'TS HAUL ROAD LENGTH & GRADE: SEE PROJ REQ'TS SWELL FACTOR DENSITIES IN PROJ REQ'TS. STEP 1 CREATE THE TABLE TO DETERMINE TRAVEL TIME DISTANCE 22% 42 TR SPEED TIME 200 LOADED X 200 200 X 200 NOTES REMEMBER YOUR 200 FT ACCEL & DECEL SEGMENTS • SPEED COMES FROM THE CHARTS ON PAGES 232 233 • TIME COMES FROM THE EQUATION ON PAGE 239 TOTAL CYCLE TIME = TRAVEL TIME (FROM ABOVE) + LOAD TIME (p235) + DUMP TIME (p 243) + TURN TIME (p243) THIS GIVES YOU HOW MUCH TIME (IN MINUTES) FOR HOW LONG IT TAKES TO MAKE ONE CYCLE. So: How MANY FULL CYCLES CAN ONE SCRAPER MAKE OUR SO MINUTE HOUR? EMPTY STEP 2:
STEP 3: How MUCH DOES OUR SCRAPER CARRY IN BOY/HR ? LOOSE CAPACITY OF SCRAPER X SWELL FACTOR X 1.1 (p231) (You CALCULATE) ↑ THIS FACTOR FOR SCRAPERS ONLY STEP 4 SCRAPER CAN CARRY MULTIPLY WHAT YOUR IN BEY TIMES HOW MANY CYCLES IT CAN DO PER HOUR. THIS IS YOUR SCRAPER PRODUCTION FOR I MACHINE IN BCY/HR. STEP 5: IF YOU ARE USING ONLY I MACHINE, HOW MANY HOURS WILL IT TAKE TO MOVE THE 7500 BCY FROM THE FARM? (REMEMBER AHR, SHE BULE) STEP 6: SET UP YOUR CREW (SEE PRAN REQTS) HRS $ per He= 1 SCRAPER C 1 D7 DIZER @ 1 GRADER @ COMPACTOR(S). HRS * $ par He: HRS $ per He= HRS X $ perte = 1 SUPERVISOR @ 1 LABORER +425 × $ HRS X $ per He- per HQ= MOVES FOR EACH PIECE NOT ALREADY THERE: TOTAL = STEP 7: WHAT HAPPENS IF YOU ADD MORE SCRAPERS? STEP & CHOOSE YOUR BEST COMBINATION HINTS: REMEMBER MOVES FOR EACH ADDITIONAL SORAPER : YOU KNOW WHAT YOUR ROLLER CAN DO PER HOUR. BE SURE YOU DON'T NEED MORE. REMEMBER THE MOVES FOR EXTRA PIECES REMEMBER THE THE + 8 HR RULES
4) TRUCKS = OFF HIGHWAY TRUCKS CARRY 15 LET OVER THE ROAD TRUCKS CARRY 10 LEY AT 75% OF THE POSTED SPEED LIMIT. 5) EQUIPMENT > • EXCAVATOR/BACKHOE & LOADER ALL HAVE 3 CY BUCKETS • GRADER NEEDED FOR HAUL ROAD MAINT • EACH PIECE OF EQUIPMENT HAS A FIXED DELIVERY OF $500 • SOIL COMPACTION REQUIRES 6 INCU LIFTS; 6 PASSES/LIFT AT 4 MPH • REPLACING TOPSOIL DOES NOT REQUIRE COMPACTION AND USES TUS D3 DOZER •ALL EQUIPMENT RUNS AT A 50 MINUTE EFFICIENCY. OPERATING COSTS/H₂ OPERATOR WAGES (INCL. BENEFITS, ETC) • OVER THE ROAD TRUCKS : $60.00 $30.00 • D7 DOZER (IDEAL: 200 LCY/H₂) = $115.00 $35.00 • 3 CY EXCOVATOR OR LOADER : $125.00 $35.00 • 120H GRADER $60.00 $35.00 • OFF HIGHWLY TRUCKS : $75.00 $30.00 • 631E SCRAPERS : $155.00 $35.00 • 5 FT WIDE COMPACTORS * $75.00 $35.00 $ $ 70,00 $30-00 • D3 DOZER (FOL TOPSOIL REPLACEMENT) • SUPERVIS02 • LABORER $50.00 $25.00 NOTE NO OVER TIME WILL BE ALLOWED ON ≤ 4 HRS = 1/2 DAY THIS JOB = 8 4es FULL DAY FOR YOUR FINAL BID USE 25% OVERHEAD + PROFIT. WE WILL DIVIDE PROJECT PART & INTO 4 SECTIONS SECTION 1 SECTION 2 STRIP THE TOPSOIL AND MOVE THE CUT ON SITE BRING SOIL FROM THE FARM USING SCRAPERS SECTION 3 BRING SOIL FROM THE FARM USING AN EXCAVATOR OR LOADER AND CHECKING IF ON ROAD OR OFF ROAD TRUCKS ARE BETTER SECTION 4 PLACING AND GRADING CRUSHED STONE, CONCRETE AND ASPHALT SUBCONTRACTORS, REPLACE TOPSOIL SUBMIT FINAL BID. 6) COSTS :
CREW REQUIREMENTS STRIP TOPSOIL: D7 DOZER (S), SUPERVISOR, LABORER MOVE CUT 3 D7 DOZER (S), SUPERVISOR, LABORER, COMPACTOR. BRING SOIL FROM THE FARM: 4) SCRAPER (<), I D7 DOZER TO PUSH AT THE FARM, 1 GRADER TO MAINTAIN THE HAUL ROAD, COMPACTOR(3), SUPERVISOR, LABORER B) 1 EXCAVATOR (SELECT EITHER A BACKHOE OR LOADER), OFF ROAD TRUCKS, 1 GRADER FOR THE HAUL ROAD, 1DT DOZER ON THE JOBSITE, COMPACTOR(S), SUPERVISOR, LABORER c) I EXCAVATOR (SAME AS ABOVE), ON ROAD TRUCKS, 1 D7 DOZER ON THE JOBSITE, COMPACTOR(S), SUPERVISOR LABORER PLACE + GRADE STONE HOW MUCH STONE DO YOU NEED ? YOU CAN ONLY PLACE & GRADE 500 ccy / DAY. (Bhrs). 1 D7 DOZER, 1 GRADER, 1 COMPACTOR, SUPERVISOR, LABORER CONCRETE SUB: HOW MANY LINEAR FEET OF GUTTER DO YOU HAVE? THE SUBS TAKES 5 DAYS: 2 TO PLACE (YOUR SUPERVISOR NEEDS TO BE THERE) 3 DAYS TO CURE. ASPHALT SUB: HOW MANY TONS OF ASPHALT DO YOU HAVE? IT TAKES 2 DAYS (YOUR SUPERVISOR NEEDS TO BE THERE). REPLACE TOPSOIL (ONLY IN THE RO.w.). THIS WILL TAKE 4 HES WITH A LOADER, THE (D3) SMALL DOBER, SUPERVISOR + LABORER REMEMBER EVERY MOVE OF EQUIPMENT COSTS $500 FULL DAYS ARE 8 HRS. (NO OVERTIME OR SATURDAYS) 1/2 DAYS ARE ≤ 4 Hes
