Revision Summaries: These summaries are for information purposes and will highlight major or substantial changes only. Each revision and specification should be reviewed in its entirety. Construction and Materials Specification Manual Index:
References and specification dates updated.

Summary of Changes to Form 400 - Specification for the Installation of Watermains:
Specification and standards references updated.
All references to the restrained lengths in Sections 400.05.01, 400.07.01 and 400.23.02 revised to read a minimum of 18m. References to 3 full pipe lengths removed.
The following wording was added to Sections 400.05.01, 400.05.02 and 400.06: The connection of any proposed watermain or water service with a diameter equal to that of the existing watermain shall only be made using a manufactured Tee.
References in 400.07.01 to PVCO pipe removed.
Section 400.12 Temporary Water Service By-Pass for Consumers requirement for proposed by-pass configuration review added.
Changes to Appendix 400-A summarized below: Existing section 2.5, Disinfection of Watermains, 2nd paragraph minimum residual chlorine levels after the high chlorine contact time have been revised from 10mg/L to 25mg/L:
The high chlorine concentration will be isolated in the system for a minimum of 24 hours and recorded on the Watermain Disinfection, Pressure Testing and Acceptance form. After the required contact time, the chlorine residual is to be taken at each sample location by the Specialist and recorded by the Construction Inspector. Flow required to take the chlorine residuals shall be provided through the temporary connection. If the chlorine residual is at or above 10mg/L the chlorine is ready to be discharged. In the event that the chlorine residual is less than 10mg/L, the chlorine in the system is to be discharged, and the system is to be rechlorinated. The Construction Inspector has the authority to require further swabbing if the residual is less than 10mg/L. Once this has been achieved, the watermain shall be flushed and sampled for appropriate chlorine residual levels. Minimum acceptable levels; Combined chlorine residual: 0.25mg/L and Free chlorine residual: 0.05mg/L.
Existing section 2.7, Bacteriological Sampling, 1st paragraph - wording revised:
Existing wording: Before the watermain or temporary above ground by-pass system can be approved for connection to the existing water distribution system all water samples shall pass both the appropriate chlorine residual and bacteriological requirements as per City of Hamilton Environmental Laboratory testing procedures. Revised wording: Before the watermain, or temporary above ground by-pass system can be approved for connection to the existing water distribution system, two (2) consecutive rounds of water samples, taken 24 hours apart, shall pass the appropriate chlorine residual and bacteriological testing requirements as per the City of Hamilton Laboratory testing procedures. Prior to chlorine residual and bacteriological testing, all other testing and disinfection shall be completed and any super chlorinated water removed from all portions of the watermain system under consideration including hydrant leads, stubs, branches, services, etc.

Existing section 2.8, Sampling Results, last paragraph - wording revised:
Existing wording: If sample results are successful the system will be put into service once a certified copy of the form entitled Watermain Disinfection, Pressure Testing and Acceptance has been received and accepted. A single failed bacteriological parameter will constitute a failure of the entire sampling round. If sample results do not meet requirements the failed section must be flushed or re-disinfected, as directed by the Project Manager and re-sampled at sample locations determined by The City of Hamilton until all water samples pass both the appropriate chlorine residual and bacteriological requirements as per City of Hamilton Environmental Laboratory testing procedures. Revised wording:
If sample results are successful the system will be put into service once a certified copy of the form entitled Watermain Disinfection, Pressure Testing and Acceptance has been received and accepted. A single failed bacteriological parameter will constitute a failure of the entire sampling round. If sample results do not meet requirements, the failed section must be flushed or re-disinfected, as directed by the Project Manager and re-sampled at sample locations. Sampling will continue until two (2) consecutive sets of water samples, taken 24 hours apart pass both the appropriate chlorine residual and bacteriological requirements as per the City of Hamilton Laboratory testing procedures.
Summary of Changes to Form 500 - Specification for Sewer Pipe Materials and CCTV Inspection: Specification references updated including references to Type HS cement. Summary of Changes to Form 700 - Specification for Portland Cement Concrete:
Specification references to Type GU (General Use) and HS (High Sulfate Resistant) cement updated.
Table 700-1 - references to 30 MPa have been revised to 32 MPa.
Summary of Changes to Form 800 - Specification for Hot Mix Asphalt:
Specification references updated.
Section 800.02 - Specification for Superpave and Warm Mix added.
List of approved Warm-Mix technologies added.
Appendix 800-A Ministry of Transportation Laboratory Testing Method LS-318 Practice for the Design of Superpave and Warm Mix asphalt added.
