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.

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!

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

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

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)

04/19/23 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)

Length: 6 ft 8 ft 10 ft 12 ftSeating: 3 / side 4 / side 5 / side 6 / side

OSHA: Occupational Safety & Health Administration Federal Standards – states (and municipalities) may enact more

stringent laws (ex. IOSH sets standards in Iowa)
