Project Overview
The City of Toronto Watermain Rehabilitation Program has been delivering Cured-in-Place-Pipe (CIPP) Watermain Structural Lining and Cathodic Protection of existing watermains for several years. In 2015, Builterra was successfully configured and delivered to the local Greater Toronto Area (GTA) consulting engineering community as a better method of delivering contract administration services to the City.
The development team at Builterra has worked closely with the participating consulting engineers (R.V Anderson, WSP, GHD, AECOM, CIMA+, Robinson Consulting, The Municipal Infrastructure Group (TMIG) and the City contractors to ensure the successful delivery of the program each year. During Builterra's first year being used by the engineer's contract administration staff, over 525 km of watermain, making up 9.5% of the city’s 5,550 km watermain distribution network was rehabilitated. Over the past 4 years, thousands of daily reports & photos, hundreds of millions of dollars in progress payment approvals have been managed and processed by engineers and inspectors using Builterra.
What is Watermain Lining?
Cured-in-Place-Pipe (CIPP) Watermain Lining is a method of watermain renewal achieved through the installation of a lining on the interior of existing aging watermains. First, the interior of the watermain is cleaned using any number of tools, including high-pressure washing and scrapers to remove any existing linings, tuberculation, and buildup to create a smooth surface. The liner, composed of either an unreinforced or glass reinforced felt tube, is impregnated with a thermos-setting resin and inserted into the existing watermain. Following installation, the liner is cured using hot air or hot water until hardened.
Water service connections are robotically re-instated from the interior of the pipe, or by tapping a new service from the exterior.
In addition to laboratory testing of liner samples, the liner quality is inspected using CCTV camera and any deficiencies are removed and replaced. All valves, hydrants, and sub-standard water services are replaced as part of the work, resulting in a renovated water system.
The rehabilitated watermain is designed to last 50 years.
Managing Chaos
The average CIPP contract value is about $12 million dollars in construction. With a large program such as the Toronto CIPP program, project teams are dealing with tens of active site locations (streets) at any given time per contract.
The Solution: Integration of Daily Inspection & Progress Payment Workflow
The Builterra mobile inspection app allows real-time mobile inspection and photo capture of any project related task.
The Builterra web inspection portal provides 24/7 access to inspection data and photos for inspector review and approvals.
Combined, the complete product provides the inspection team, contract administrators and external contractors with an easy, seamless solution to implement complex daily reporting with direct access to the online contract item description and quantity for progress payment reporting and approvals.
