Scope of work:
NOTE: Appendix E and Appendix F are provided as separate Attachments.
2.1.1 In 2014, the City of Toronto prepared a comprehensive guideline for applying the InfoWorks computer model to conduct Basement Flooding EA projects. The purpose of the guideline was to provide detailed procedures, methodologies, and guidance for setting up and applying the InfoWorks CS model for the analysis of the storm and sanitary drainage systems for basement flooding studies. The purpose of this Request-For-Proposal (RFP) is to select a Proponent to update the 2014 modelling guidelines to reflect the evolution of the document through the latest basement flooding EA studies, address the change of modelling software from Infoworks CS to ICM, and introduce other improvements.
2.1.2 The InfoWorks basement flooding studies model guideline was prepared to ensure that model set-up, model calibration/validation, hydraulic performance and alternatives analyses, and documentation procedures are applied consistently in different EA studies by different Consultants. To this end, the modelling guideline is to facilitate and make it quicker and easier for consultants to set up the model and conduct analyses for the basement flooding EA studies. And the guideline also assists the City with its reviews and in ensuring that modelling standards are upheld.
2.1.3 Table of contents for the 2014 model guidelines document is included in Appendix E.1.
2.1.4 The 2014 model guidelines document is included in Appendix F.
2.2 PROJECT OVERVIEW
2.2.1 The following section is intended to provide the Proponent with an understanding of the specific parts of the project as developed by the City. Items not specifically listed, but required to provide fully functioning systems and to meet the intent of the City, are deemed to be included in the base scope.
a. Project Objective
1. The overall objective of the modelling guidelines is to bring consistency to the models created through the Basement Flooding studies and outline the minimum requirements for such models. The guidelines are expected to be flexible enough to allow for innovative approaches, if they are an improvement over the guidelines.
2. The ultimate goal is to streamline the application of the Infoworks model, improve the efficiency of model review and accelerate the delivery of the Basement Flooding EA studies.
3. Since 2014, many changes have occurred. Innovyze has upgraded InfoWorks from CS to ICM and some modelling guidelines have been revised and expanded during the EA studies. QA/QC requirements and check lists have also been added. The scope of this project, to be completed by the Consultant, shall include the tasks listed below:
a) Review the 2014 City of Toronto InfoWorks Basement Flooding Model Studies Guideline to identify items that need to be revised, and incorporate the revisions in an updated Guideline;
b) Solicit comments and input from engineering firms who have conducted Basement Flooding EA studies using the 2014 InfoWorks Modelling Guideline, review information from other sources (e.g. in United Kingdom and United States) in relation to InfoWorks modelling, and incorporate the relevant procedures and methodologies in the updated Guideline;
c) Add new chapters in the updated modelling guideline, as required; and
d) Prepare and submit the revised City of Toronto InfoWorks Basement Flooding Model Studies Guideline.
b. Project Schedule
1. The approximate timeline for this project is expected to be eight (8) months. This is only the City’s suggested timeline. If the Proponent considers the timeline too short or too long, identify this clearly in the Proposal. Within the Proposal, the Proponent is responsible for identifying a timeline that it is committed to accomplishing. The Consultant's ability to maintain the proposed schedule will be evaluated in the performance review at various stages throughout the project.
2.3 PROJECT ELEMENTS
2.3.1 The following section is intended to provide the Proponent with an understanding of the specific parts of the project as developed by the City in conjunction with the Appendices. These tasks are considered to be base scope. Where there is a conflict, the provisions in this section shall take precedence.
2.3.2 A detailed description of the project tasks is provided as follows:
a. Task 1 – Review 2014 City of Toronto InfoWorks Basement Flooding Model Studies Guideline
1. The Consultant shall review the City’s 2014 modelling guidelines to identify items that need to be updated and revised for improvements, corrections, or clarity. The guideline needs to be revised from the CS to ICM terminology environment. There are sections that provide too much direction, and others not enough, or require clarifications in the way of examples. The latest InfoWorks ICM modelling techniques, and current publications and research relevant to modelling guidelines and application of InfoWorks ICM in United Kingdom and United States shall also be reviewed, and the information incorporated for this update. Additional suggestions for improvements to the guidelines are provided in Appendix E.2. Following the review, the Consultant shall prepare a summary list of the findings. It is not necessary to include all suggestions in the list, but rather the items that help achieve the project objectives. The list will be discussed with the City and finalized by the Consultant as part of the Technical Memorandum.
b. Task 2 – Obtain Input and Propose Changes to Guideline
1. The Consultant shall solicit input and suggestions from engineering firms familiar with the 2014 modelling guidelines, especially those who are conducting the City’s Basement Flooding EA studies. Input from other sources, such as engineering firms who had previously conducted City’s EA studies, or engineering firms who have experience in applying InfoWorks ICM in other projects, can also be obtained by the Consultant. Where appropriate, the Consultant shall address and incorporate this input in the updated Guideline.
2. The Consultant is to organize and chair one (1) workshop with the City and engaged engineering firms (3 – 5 firms) to discuss the input/suggestions and reach consensus on the changes to be made to the guideline document by the Consultant..
3. During this task, some model tests or model sensitivity runs may be required using InfoWorks ICM. The scope of such modelling is to be based on suggestions in Appendix E.2.
4. Prepare the Technical Memorandum, which shall summarize the work done as part of Tasks 1 and 2 and provide the Consultant's recommendations for changes to the Guideline for the City's review.
c. Task 3 – Produce New Chapters
1. The Consultant shall add new sections in the Guideline to include methodology, steps, and guidelines for:
a) Cost per Benefitting Properties calculations
b) Modelling combined sewer areas
c) Investigating and modelling dual maintenance holes
d) Modelling perforated maintenance hole lids
e) Modelling ditches, and incorporating ditches with the major system
f) Application of climate change IDF curves
g) Using radar rainfall to improve rain data accuracies
h) Accounting for grease and sediments in sewers when developing solutions
i) Accounting for external areas, overlapping boundary conflicts
j) QA/QC requirements and check lists
2. The technical memorandums that were prepared during previous EA studies for some of the above topics, except items g) and i) above, are included in Appendix E. The Consultant shall review, update, and incorporate them in the revised Guideline as new chapters.
3. Again, during this task, some model tests or model sensitivity runs may be required using InfoWorks ICM. The scope of such modelling is to be based on the new chapters listed in Task 3.
d. Task 4 – Prepare and submit the revised guideline.
1. The Consultant shall submit an updated guideline, incorporating the information and findings obtained in Tasks (1), (2), and (3).
2. A table listing all of the changes and additions to the guideline shall be submitted with the deliverable. Each change and addition should be characterized and the anticipated impact on model set-up and review times quantified. The intention is for the City to be able to review the impacts of the proposed changes and select the ones that best meet the project objectives.
3. The Consultant is to organize and chair one (1) workshop with the City and engaged engineering firms to review the draft revised Guideline document
