2. Assignments • Current Assignment: • HW 5: Team Assignment, 2 people per team, turn in 1 HW set per team. • b.) assume separate restrooms, industrial facility (non-foundry) and assume they want minimal space increase • Next Assignment: • Prep for Exam II Parking Lot Problem, 2 people per team – see next slide • Measuring tools are in the MIL Lab (IER 310) on the South blue pegboard • Return the tools ASAP • Layout the parking lot according to the handout heuristic • Show your work (for your OWN benefit) • Put this on EP paper for your use on the second exam and keep it in your engineering notebook. • Exam dimensions and design constraints may be similar, but different. • Good idea to clearly document what you did, so you can adapt your model for the exam quickly.

3. Questions & Issues • Exam II Parking Lot Design Problem(prepare ahead for exam!): • Measure the IER parking lot AND the gravel area to the East for: • Location of utilities, side walks, building entrances & walls – considering them to be Monuments • Monuments are things that cannot be removed or relocated – like pillars • Dimensions to the nearest foot (rounding down) • Assume curb cuts, sign posts & foliage can be moved • Assume the width of the level part of the curb cut is the same as the width of a cross aisle (if any cross aisles are needed) • Using the Parking Lot Design handout, design the most efficient lot possible if the strategy for the lot is to allow quick turnover, and: • 90o parking must use the stall width midpoints, others can use smallest stall widths • 2% of the stalls are handicapped accessible (use largest stall width) • 10% of the stalls are for compact vehicles • 10% of the stalls are for large vehicles • Bumpers can overhang the sidewalks to the South and East, but not the West • Bumpers cannot encroach on the alley, or the garbage truck will hit them!

4. Personal Space Design • Spaces vary depending on facility purpose • Examples: • Walmart • 7-11 / Convenience Store • Convention Center • Religious Center • High School • College Building • Hospital • Prison IENG 471 Facilities Planning

5. Personal, Sanitation Requirements • Personal Requirements: • 6 ft2 per person - personal space • Toxic material handling requires change of clothes, showers • Weather conditions may require outerwear storage • Sanitation Requirements: • Restrooms within 200 ft of permanent workstations • Separate sex restrooms are required, unless sufficient single occupancy rooms are provided • Number of accommodations vary by facility type (see Table 4.2) • 15 ft2 per entrance, screen interior from outside view • 6 ft2 per sink, unless using basins (24” linear or 20” arc /person) • 12.5 ft2 - 15 ft2 per toilet • 6 ft2 per urinal (can replace up to 1/3 of toilets for males) • Aisle width increases with length, and if stall doors open outward • Female accommodations may include cots – allow 60 ft2 / cot IENG 471 Facilities Planning

6. Dining, Food Service Requirements • Dining Requirements: • Food consumption may not occur in manufacturing areas • 30 minutes is the minimum lunch shift for Federal requirements • First 1/3 of dining shift is spent acquiring / preparing food, so shifts may overlap by up to this amount • Food Service Requirements: • Off-site food service requires longer dining shifts • On-site space should be located within 1000 ft of permanent workstations • On-site vending machines require 1 ft2 per person (food prep) and a break room to sit and eat • On-site catering (with serving lines) is feasible at about 200 employees • On-site kitchen (and serving lines) is feasible at about 400 employees • A serving line typically requires 300 ft2 and serves 7 employees / minute • Kitchen space is for food preparation,cafeteria space is for seating (see Table 4.5 for kitchen space required / meal served in a lunch shift) • Cafeterias may double as break rooms (see Table 4.4 for space / seat) IENG 471 Facilities Planning

7. Cafeteria Tables • Typical table height is 29 – 31 inches • Square Tables • Typical seating is 4 persons • Typical table sizes are 36”, 42”, and 48” wide • Round Tables • Typical seating is 1 person every 30” of circumference • Typical table sizes are 30”, 36”, and 42” in diameter • Rectangular Tables: • Typical table width is 30” • Typical lengths and seating / side is given in the table below: • Tables may be placed end-to-end for maximum efficiency • If end seating is to be used, reduce seating / side by 1 person (over the entire length) IENG 471 Facilities Planning

8. Other Requirements • Workstation Requirements: • Drinking water should be provided within 200 ft of workstations • Break rooms should be within 400 ft of permanent workstations • 30” minimum aisle widths are required between stationary objects • 36” minimum aisle widths are required between a stationary object and an operating machine • 42” minimum aisle widths are required between operating machines • Recommended Office Spaces: • President’s Office: 250 – 400 ft2 • Vice-President’s Office: 150 – 250 ft2 • Executive Office: 100 – 150 ft2 • Partitioned Space: 80 – 110 ft2 • Open Space: 60 – 110 ft2 • Conference Rooms: 20 – 30 ft2 / person, (15 ft2 if theater style) • Reception: 125 – 200 ft2 (receptionist and 2-4 persons); 200 – 300 ft2 (receptionist and 6-8 persons) • File Room: 7 ft2 / file plus a 3 – 4 ft aisle width IENG 471 Facilities Planning

9. Summary of Codes & Standards • Workstation Accessibility Requirements: • Able-bodied clearance and reach requirements are shown in Figure 4.11 • Wheel chair clearance and reach requirements are shown in Figure 4.10 • Common accommodation aisles run 3 – 3.5 ft in width • Common seated easy reach zone runs 3 – 4 ft high • Code / Standard Compliance: • International Building Code covers use and occupancy classes • NFPA 101 Life Safety Code covers occupancy and exits • International Fire Code covers fire safety and access constraints • ADA and ICC/ANSI A117.1 covers accessibility of facilities • ICC International Energy Conservation Code covers climate ctrl • IAPMO/ANSI UPC 1 Uniform Plumbing Code covers sanitation • NFPA 70 National Electric Code covers electric & utilities IENG 471 Facilities Planning
