Markham City Standard to be Followed for this Project

ROADWAY DESIGN : Follow: OPSD600.040 and MR20,MR4

2 Way Urban lane= 9.25M Crown Undivided lane SLOPE .02 DESIRABLE MINIMUM K VALUE FOR CREST4 SAG 7 THICKNESS:HL3=40MM,HL8=75MM(LIFT ONE) BASE 150MM(20MM CRLS) SUBBASE 300MM (50MM CRLS)

Lane (W): 3.95m+Curb:.2m+Gutter:325m+BLVD(In)=3.0m Sidewalk:1.5+BLVD(Out)=.3m

Lane (H): Curb:A=.225B=.3m,C=.025,D=.15, E=.2mF=.15,Curb radius and Gutter Radius is used R5 and R25 (as noted),otherwise need permission from directors of engineer,City.

WATERMAIN(COVER:1.75):PRESSURE PIPE,ELBOW,TEE AND GATE VALVE HAVE BEEN USED.

LOCATION:ON STREET LINE, 1.75M BELOW FROM CENTERLINE(NORTH AND EAST DIRECTION),LOOPED.CULVERT AND CLEARANCE NEED TRCA AND MOE PERMISSION.

DIMENSION:DUCTILE IRON, UPTO 300 MM DIA.,USE AWWA C-152 STANDARD=AD THICKNESS.

STORM(COVER:2.50) AND SANITARY(COVER:2.75):OPSD 701.010 :GRAVITY PIPE:.02 TO .08 SLOPE HAS BEEN USED.MAX. LENGTH=200M

PRECAST CONCRETE COMPONENT:701.03,701.031,701.032, DIA:1200MM(MH).

LOCATION:1.5M FROM CENTRELINE.

  1. Drawing plans and profiles: Creating technical drawings (general plans, profiles, and detailed designs) for infrastructure like roads and sewers.�
  2. Hydraulic analysis: Using Manning’s and Darcy-Weisbach equations to design and analyze flow in sanitary and storm sewer systems, including computing Hydraulic Grade Line (HGL) and Energy Grade Line (EGL).�
  3. Code compliance: Ensuring design aligns with Markham City engineering standards, Ontario Provincial Standards (OPSS/OPSD).�
  4. Efficient earthwork calculation: Using tools (like Civil 3D) to optimize excavation and grading work for cost-effective project execution.

CONCLUSION

​

EASY TO MODIFY BECAUSE OF DYNAMIC OPTION IN 3D PLATFORM

  • Explore: Interactive and dynamic design functionality in civil 3D for project : BY LAWS:MARKHAM CITY

WHAT: Follow respective city specification and design code

  • Model development in civil 3D for SUBDIVISION

HOW: BASE AND CONTOUR HAVE BEEN PROVIDED as a case study area for urban 2 way lane.

  • Implementing MARKHAM CITY BY LAWS MTO design code and specification in civil 3D.

CONCLUSION AND DISCUSSION:

Possibility and implication for many other civil infrastructure application or facilities: Specially: a) Geotechnical, b) Water main, Sanitary, Storm water system c) Hydrology and Hydraulic analysis and computation (Rainfall-Runoff model:Ex:Waterbudget), WHILE all gravitational flow has been treated as open channel flow :Darcy and manning need to be considered for all engineers.

-100 yrs computation but 2yrs to 5yrs computation for any city requirement including water balance.
