2. Water

The contractor shall obtain water from commercial sources. The city cannot provide water for this contract.

3. Work Area

The routine work shall be undertaken in any area of the City as instructed from time to time by the Engineering Department.

The first set of basins to be cleaned are those that have not been cleaned within the last 15 months. These basins are located throughout the City, with a higher density in the downtown area. The location of these basins are shown in Attachment 1. It is required that all basins are cleaned once before a basin is cleaned for the second time, unless specifically instructed to by the City Engineer. Consistent with this, all basins must be cleaned for a second time before they can be cleaned for a third time, and so on.

Contractors shall familiarize themselves with all areas of the City to ascertain conditions prior to submitting their bids.

4. Priority Catch Basin Cleaning

At times, the City needs particular catch basins cleaned within a short time period, namely three (3) working days. The "Priority Catch Basin Cleaning" item exists to cover any additional costs associated with scheduling the cleaning of singular, assigned catch basins.

These catch basins may be located in all areas of the City. Priority Catch Basin assignments are to be completed within three (3) working days of assignment.

5. Pipe Jetting

The City shall advise the Contractor from time to time of locations where pipes are clogged and in need of cleaning. The Contractor shall undertake the cleaning within fourteen (14) calendar days of being advised of these locations. Pipe jetting locations are most likely to be of catch basin lateral pipes and so should assume shorter lengths of pipe to be cleaned at each assigned locations

(typically 10-30 feet). As far as is possible, several locations will be instructed at one time. However, isolated sections of pipe may require cleaning from time to time.

6. Supplemental information to be submitted with the bid

The contractor shall submit the following information with their bid:

(i) The location of their staging area for dewatering and storing catch basin wastes. This shall include pro-forma documentation from the owner of the site indicating their willingness to enter into a rental agreement with the Contractor if the site is not already owned by the Contractor.

(ii) The location of the final disposal point for the solid wastes from the catch basins.

(iii) The location for the disposal of liquid wastes from the catch basins. It must be noted that decanting in to sanitary sewers is prohibited.

7. Contract Length

This contract is for one year, with the option for two one-year renewals each year after.

8. Permits and Traffic Control

The Contractor will be responsible for all permits necessary to complete the work. A City

Obstruction permit will need to be obtained for this work. In addition, it is the Contractor's responsibility to provide Trafficperson in instances where they are necessary for the safe implementation of the work. The Contractor shall also use other methods of traffic protection as described in the Section 32.04 of the Specifications as appropriate. Payment for the uniformed trafficperson is a pass-through cost covered by an Allowance as shown in the bid table.

9. Record Keeping and Invoicing

To document maintenance activities, the ArcGIS Field Maps application will be used. The

City will provide the Contractor with access to the ArcGIS Field Maps app for use of documenting maintenance activities. The ArcGIS Field Maps app is free to download and will be no cost for the Contractor to use. The app can be downloaded and used on any smartphone or handheld device (ipad, laptop, etc). The app allows for uploading of photos, notes on condition of catch basins, and keeps track of dates when maintenance work was conducted and will be used for invoicing purposes. Invoicing is to be submitted monthly.

Each operator will need to create their own account. There is no cost for multiple accounts.

When logging catch basin cleanings, the Contractor is required to upload at least three pictures to the ArcGIS Field Maps app for documentation. These pictures will include a before cleaning, a during cleaning, and a post-cleaning image showcasing the basin appropriately cleaned. The Contractor is also required to upload the condition of the basin, the type of cleaning being performed, the sediment depth, the jet length when applicable, and any relevant notes. If there are any issues in completing any of these steps, the Contractor must immediately inform the City Engineer in an effort to resolve the issue and utilize an alternative tracking method (i.e. paper maps, etc) until resolved
