1 TERMS OF REFERENCE PROJECT EDINBURGH ROAD FROM SPEEDVALE AVENUE TO LONDON ROAD OBJECTIVES/PURPOSE The City of Guelph intends to upgrade the underground services to current standards and carry out complete roadway reconstruction on Edinburgh Road from Speedvale Avenue to London Road. The hiring of Consultant Services is to be considered as an extension of City Staff and as such Consultant Staff are expected to conduct themselves as representatives of the City. City Staff will be part of the Project Team to provide limited support and guidance to the Consultant(s) as required. The Consultant(s) shall complete the preliminary design, final design, coordinate all related project needs, tendering, contract administration and resident services during construction of improvements to the roadway, underground services, drainage, traffic services and other related infrastructure. A dedicated and independent environmental Inspector is to be provided for to ensure that the environmental protection recommendations in any agency approval conditions are complied with during the Road reconstruction period. All design work must be completed in accordance with City of Guelph standards. In conjunction with the normal utility agencies affected by the proposed works, design considerations and streetscape improvements are to be coordinated with the Neighbourhood Association (if one exists), and any other special interest groups or County and City Committees and Departments. PROJECT MANAGEMENT REQUIREMENTS It is expected that the Project Manager for the consultant will coordinate all aspects of the preliminary design, final design, administrative, construction and maintenance phases of the Project. The Project Manager will be the primary contact for the City and Contractor and any related agencies. Quality Assurance will ultimately rest with the Project Manager. GENERAL SCHEDULE Final Design of Projects to be complete by December Anticipated construction tender to occur in January Public Information Centres shall be held at 60% design and prior to tender advertisement.

Prepare and submit MOE - Certificate of Approval Applications (Application fees will be paid by the City). Liaise with other relevant agencies including arranging and attending meetings, preparation of meeting agendas and minutes, and preparation and submittal of applications for agency approval as required (Application fees will be paid by the City). Liaise and coordinate services within the project area as required (e.g. waste management pick up and routing, Canada Post, Guelph Transit, Goderich Exeter Railway, Utilities, etc.). Provide an Engineer s Estimate for Total Project Construction Cost at the following stages: Preliminary estimate with Proposal for Consultant s Work Plan and Fee Estimate. Detailed estimate at 90% and 100% Design. Final Detailed estimates one week prior to the close of the tender. Reproduce tender documents and drawings (allow 10 sets hard copy) and submit digital drawings in both AutoCAD and PDF format. Answer questions from contractors during the bidding period and if required, prepare Addenda to be distributed by the City to all registered bidders. Review tender submissions for mathematical accuracy, check contractor references as required, provide a cost comparison for each bid item for all bidders and make a recommendation for tender award TR3

4 Stage 2 Construction Services (provisional, subject to City requirements) The consultant shall provide the following construction services: Organize, attend and document a pre-construction meeting and bi-weekly construction meetings. Provide full-time resident inspection of construction services. Provide environmental specialist inspection services as required for compliance with GRCA fill permit requirements, tree impact requirements and Migratory Bird Act requirements. Provide Contract Administration services including preparation and recommendation of progress payment certificates and change orders, review and recommendation of shop drawings and provide all public relations activities including but not limited to preparation of letters, mailing or hand delivery to all resident-owners, non-resident-owners and occupants in project area plus one block on side streets in all directions (refer to Appendix B - Capital Project Mailing requirements) and follow up on all complaints and claims. Provide post construction services, consisting of Construction Record drawings in printed and digital.autocad dwg file format, warranty inspection and administration. TR4

Complete necessary field investigations/testing to prepare an engineering report with recommendations pertaining to excavations and dewatering, pipe bedding, ground water control, trench backfill, roadway construction, pavement structure and compaction requirements. Identification of the presence of any potential contaminated or unsuitable material and recommendations with regard to further testing including applicable chemical testing. Please note that this type of issue would be considered unforeseen and a reasonable cost for testing would be considered. General - Consultant Responsibilities: The consultant shall immediately inform the City s Project Manager of any critical defects or deficiencies and unsafe conditions which are discovered in the field during the work. The consultant shall immediately inform the City s Project Manager of any contamination encountered during drilling and of any potentially contaminated sites based on site usage which are observed in the field during the inspection. Additional boreholes may have to be carried out by others (not part of this assignment) to determine the type, depth and limits of the contamination.

14 The geotechnical consultant shall remove any groundwater monitoring wells prior to constructions and no additional cost to the City. Final Documentation 1.

Borehole log sheets undertaken on roads and shoulders, where available. Borehole location plans. Grain Size Distribution consisting of grain size analysis tests, and where applicable, particle size (hydrometer) tests. Grain Size distribution shall be plotted against upper and lower band limits for various material such as Granular A and B, in accordance with Ontario Provincial Standards (OPS) materials. Based on the testing results, the report shall provide a recommendation relating to the suitability of the in-situ material being used for Granular A and B. Standard Proctor Moisture Density Test Results.
