A little re-cap (from memory)...

I'm springing a little pop-quiz on myself tonight. 




If you'd like to do this, read through my blog posts to date, let it all gel overnight and tomorrow. Tomorrow night, number a paper (or Word Document) from 1-10. Then write down the (10) tips from my posts that will help you (from memory!!). OR better yet, re-cap from your own test prep!

Directions:

List 10 tips, strategies, and facts that you've identified and retained over the past month. 

  1. Lighting: Calculate wattage allowed before going all symbol-crazy on your plan (watts per SF X total SF) and keep track of watts as you add fixtures. 
  2. Egress: To determine the travel distance to each stair, remember to add your farthest path traveled within the existing suite to to the common path of travel to each stair. 
  3. ADA Restroom: 36H rim std lav, 34H rim ada lav, 15H t.o. seat std toilet, 17H t.o. seat ada toilet, 24H to rim std urinal, 17H to rim ada urinal, 34H t.o. grab bar, 40H to b.o. mirror, 40-44H to operating parts of wall-mounted accessories. Oh, and 30X48 access in front of sink/urinal. 
  4. Systems Integration: Pay attention to ceiling height changes with regards to ductwork!
  5. Millwork: draw blocking in the wall and OVER-label everything!
  6. Egress: use the "grid-block" space planning method to divide your floor into designated spaces (find SF of a grid block and divide each required SF to determine roughly how many grid-blocks). 
  7. Life Safety: 1-hour rated walls belong suite-suite, suite-public corridor/lobby, and assembly-suite corridor, should have acoustical properties, and extend to the underside of the deck. 
  8. Lighting: Assign DLV (dimmer low voltage) to low-wattage fixtures when laying out switching plan. 
  9. Life Safety: You need a Fire Extinguisher both in the shared lobby/corridor AND in the tenant space (usually they'll have a space with enough SF requiring TWO and they should be located no more than 75' from the further occupant. 
  10. Space Planning: Pay attention to plumbing trenches, don't forget to locate required electrical outlets/data as required, and highlight the program as you go!
There are more, but these are my faves!

Happy re-capping!

Egress Exercise: A Smart Approach


A few strategies to keep in line with the clock...If you're like me, you know all of this but creating an accurate plan within an hour is tough!

cute calculator from anthropologie

  • Before you even start, roughly determine each space's Occupancy using the provided minimum SF in the program. Doing this early on gives you an idea of which space will need two doors! HINT: it's usually the Assembly space!
  • Write Space Names into chart on vellum - an on-sheet checklist!
  • Using your grid lines on the plan, find the SF of (1) grid block; Divide by (2) for half block. My husband taught me this logical method!
  • Next, divide the minimum SF provided for each space by (1) grid block SF to determine how many "blocks" & "half blocks" per space. This allowed me to lay out the entire floor in less than TWO MINUTES!

{ EXAMPLE }

A 1200 SF minimum cafeteria
Block SF = 325 SF

1200 / 325 = +/- 3.75 grid blocks 

  • Recessed doors = 15 SF (5' wide by 3' deep) which can affect the SF of your space. If it helps, add door SF into each minimum SF before drawing out spaces so you don't risk going under the minimum. If you have a 1280 SF rectangle without your recessed doors drawn in, you can now place your 5' wide by 3' deep recess without losing 15 SF.

{ EXAMPLE }
1250 SF minimum cafeteria
1250 / 15 = 84 (>49) = (2) doors 
2 x 15 SF = 30 SF 
1250 + 30 SF = 1280 SF Min
  • Sketch rough wall-lines using "blocks"created by the grid on trace paper over plan.
  • Slide your trace under the vellum test sheet to trace final plan.
  • Write in Space Names & Actual SF as you go.
  • Add doors recessed 3'-0" in from corridor with 12" on push side and 18" on pull side (see above).
  • Calculate actual Occupancy factor with your actual SF by referencing the provided Occupancy Load Chart
  • Then continue with your "travel distance," "door placement and reasoning," "stair distance," and load per stair. Divide by (2) if there are (2) stairways.
    • If you have an odd total divided by 2, it will look something like this:

59 / 2 = 29.5
Translate to: 29 for stair #1 and 30 for stair #2
  • Remember: the total travel distances to the stairs =

farthest path of travel within the existing suite
+ 
common path of travel to each stair once in the corridor
