Lean Docs - Part 3

This Workflow below wraps up discussion of one drawing system that can be implemented into a Lean practice - there are many more.  It is based on over 20 years of use of the system.  Yes, it does repeat some information previously shared in earlier posts, but is combined here together into a teachable workflow.

Workflow for Toilet Types System

DESIGN

Develop floor plans with toilet room layouts.  Model and draw accurately and be sure to design to meet accessibility requirements, where applicable.  The included 1/4" scale vignette toilet fixture plans on the Toilet Types sheet already provide dimensions and fixture tagging, and for the accessible fixtures, complies with current accessibility guidelines.

CD’s

Review and edit the Toilet Accessories Schedule for your project.

Add your project specific 1/4" scale enlarged toilet room plans onto this sheet and name them T2, T3, etc.  Note that T1 is reserved for the typical, single occupant, accessible toilet room.

  • “Plug” the applicable vignette drawing designations (WC1, S1, S2, ST1, etc.) onto your enlarged plans using 12” BOLD Arial text (so it stands out)!
  • “Plug” the T1, T2, T3, etc., designations onto your 1/8"scale floor plans.

Review & edit the 1/4" scale vignette toilet fixture plans for any accessory changes you want to make.  Some common edits are:

  • Sink vignette drawings have a tendency to change per project.
    • Your 1/4" scale enlarged plans showing counters with multiple sinks, such as in large, multi-occupant bathrooms, are the place to indicate locations in context with the actual wall layout for paper towel and soap dispensers.  In this instance, the dispensers are tagged both on the S1, S2, etc., vignette drawing and then again on your enlarged toilet room plan.  (Yes, this is a small compromise in duplication to ensure understanding by the contractor)
    • On some projects it may be preferable to locate soap dispensers in the field with the Owner and Contractor during construction.  If so, note that on the S1, S2, etc., drawings accordingly.

  • Showers can be similar to sinks and it may be helpful indicate the actual locations of towel bars and robe hooks on the 1/4" scale enlarged plans (for context in the actual room layout).  Again, the SH-1 or -2 vignette drawings still show & tag all accessories.

SPECIFICATIONS

They should reference the drawing for the Toilet Accessories Schedule and provide a list of other acceptable manufacturer’s.

BIDDING

Draw the contractors attention to this scheduling system for Toilet accessories and how it works at the Pre-Bid or review it beforehand with your Design-Build partner.

CA

Go over how this system works with the contractor's field superintendent.  Review the Toilet Accessories and Toilet Partitions submittals with this sheet.

DO'S & DON’TS

Do not elevate bathroom walls to show fixtures in elevation as fixtures are already elevated on the Mounting Heights drawings.  You may elevate the walls to show atypical tile patterns or other design features.

  • Note that a "reference elevation" may suffice for wall tile as it provides the graphical "rules" on how tile is installed, i.e., wainscots & repeating tile patterns w/ applicable dimensions.
  • If you need to elevate walls, do NOT retag the accessories or repeat dimension already provided on the vignette plans.  Remember,  the Toilet Types sheet is the only place in the documents providing that information.
  • Also, the toilet partitions are a manufactured item and do not need to be shown in elevation for the contractor to be able to bid or prepare shop drawings.
