Standards Engineer’s First Roller

Incorporation of Accessibility Design Standards into Volume 1

3

F-3512 TACTILE WALKING SURFACE INDICATORS (TWSI’S)

New SP outlining the installation requirements for TWSI’s.



TWSI’s shall one of the approved cast-in-place, cast or ductile iron products described in MS-13.1 and listed in MS-22.15.



Multiple plates shall be bolted together with Stainless Steel bolts and nuts.

4

F-3512 TACTILE WALKING SURFACE INDICATORS (TWSI’S)

From the Accessibility Standard (Part of detail drawing SC7 shown)



TWSI’s shall be set back 150 to 200mm from the back of curb.



TWSI’s shall be 610 to 650 in depth and a minimum width of 1500mm.



For curb ramps and single transition areas, TWSI’s shall extend the full width of the curb ramp/area.



All TWSI’s shall have 6mm wide x 6mm deep drain grooves at corners between the TWSI and the curb. Panel joints may be adapted for use if touching.

5

F-3512 TACTILE WALKING SURFACE INDICATORS (TWSI’S)



Unless indicated otherwise on the contract drawings for blended transition areas (dropped corners?) serving two crossing directions provide .3m gap between the TWSI sets.



Plates shall be parallel with the curb radius (i.e. not necessarily perpendicular to the direction of pedestrian travel). This will require the use of radius TWSI plates in some instances.



Radius TWSI’s are available in various radii. Careful consideration of radius design is required as the TWSI radius shall follow as close as possible the back of curb radius.

Note Natural uncoated finish for concrete

6

F-3512 TACTILE WALKING SURFACE INDICATORS (TWSI’S)



Tops of TWSI’s shall be aligned and level with the adjacent concrete surface and installation in wet concrete shall be effective in permanently securing the TWSI in place once dry.



Measurement will be the area of TWSI’s in m².



F-3510 and F-3511 (Sidewalk Construction Specs) also updated to include TWSI’s.



4 Approved suppliers on approved list. MS-22.15 shown below.

7

F-4070 MH’s, CB’s Ditch Inlets and Chambers



Self-level Catch Basin frames now approved but limited to one supplier at the moment.



Requirements are described in MS-13.1 and the approved supplier is listed in MS-22.15. Conditions of the approval have since been satisfied.

Adapter plate required for square CB’s.

F-4080 Adjusting or Rebuilding MH’s CB’s …..

 Same as F-4070, self level surface inlet Catch

Basin Frames and Covers now approved.

allowed, to be prevented to reduce chances

(Page 6)

Before Now

F-4081 Self Level Maintenance Hole Frame and Cover

Installation on Existing/Retrofit structures

 Structure to be minimum 250mm below surface

depending on manufacturer. 150 to 230mm

• typical. East Jordan 250mm high so more room

needed.

 Section 7 modified to stress the importance of

putting generous quantities of asphalt under the raised lip so it sits about 25 to 38mm higher than the surrounding asphalt before rolling. Also using better pushing tools than the sharp end of a shovel is suggested.

11

F-4081 Self Level Maintenance Hole Frame and Cover

12

F-4081 Self Level Maintenance Hole Frame and Cover

 Section 8 now requires compacting to start

from the outside and work towards the centre to ensure compaction of the material under the lip.

13

F-4081 Self Level Maintenance Hole Frame and Cover

• New section 9 to stress that the

upper frame is not to rest on the guide frame otherwise will loosen and rock causing noise complaints, possible damage to the frames and possible ejection

• f the cover, possibly leading to

an accident.

• Picture - 311 forces replaced
• riginal SL F&C with regular

F&C after a noise complaint.

• Changed back to SL before

completion.

14

F-4100 PIPE SEWERS

 Page 4 – Cored Tees approved for years but not

mentioned in F-4100 and now they are.

15

F-4100 PIPE SEWERS

 Gap at top of PVC sewer pipes when using Kor-

n-seal connectors has been resulting in cracks/breakage during cleaning operations.

 Obvert to be cut back 50mm to reduce stress on

• bvert when using Kor-n-seal. See page 5.

16

F-4451 WATERMAIN CLEANING AND STRUCTURAL LINING

 Many clarifications made to ensure

that the end result will be a structural lining with a sleeve/jacket not just a spray coating. Old spec was inconsistent.

17

F-4491 COMMISSIONING OF WATERMAINS

 Page 3 Nozzles

are no longer to be installed on hydrant laterals.

 Nozzle removed

from hydrant lateral on associated drawing W46.

18

F-4493 TRACING WIRE FOR WATERMAINS …..



From page 2 of 4493.



W36 revised to show extension of wire for PEX.



OK to use the same wire as specified tracing wire is superior to wire specified in OBC and OK’d by John Buck.

MATERIAL SPECIFICATIONS

 The primary purpose of the material

specifications is to outline the technical requirements for products prior to approval.

 After approval, products are listed in

the appropriate list of approved products.Water MW-19.15; Sewer (TWSI’s) MS-22.15.

Accessibility Standard Applied to Sidewalk Drawings

Accessibility for Ontarians with Disabilities Act, 2005 Exceptions, General 80.31 Exceptions to the requirements that apply to exterior paths of travel are permitted where obligated organizations, other than small organizations, can demonstrate one or more of the following:



• 6. - It is not practicable to comply with the requirements, or some of them, because

existing physical or site constraints prohibit modification or addition of elements, spaces or features, such as where increasing the width of the exterior path would narrow the width of the adjacent highway or locating an accessible pedestrian signal pole within 1,500 mm of the curb edge is not feasible because of existing underground

• utilities. O. Reg. 413/12, s. 6.

(Therefore no expectation exists in the Act to expropriate land or narrow the road surface to generate more room for curb ramps. Also the Ottawa Accessibility Standard mentions “blended transitions” for traffic calming locations but currently has no drawing example to show what that should look like.)
