Municipal underground infrastructure is becoming increasingly congested with the addition of utilities ranging from sewers, watermains, gas, power, telephone and other pipeline networks. Coordinating a repair to deteriorated sewer and watermain networks has become a major undertaking. With the potential for damage to other utilities, the inconvenience to the public and the high cost of restoration, trenchless rehabilitation of sewer and watermains has become the preferred construction method in urban areas.
Course OutlineAs one of the core courses in the epCIP program, the Trenchless Rehabilitation course will provide in-depth knowledge of rehabilitation selection, techniques and design methods. Upon completion of this course the civil infrastructure professional will acquire a comprehensive foundation of knowledge and skills relating to:
- Selection criteria – rehabilitation versus new construction, structural versus non-structural, localized versus full length, bypassing, direct and social costs and environmental impacts.
- Design methods – non-structural, structural (flexible and rigid liners), site investigation, risk assessment and life cycle costing.
- Techniques – repairing mainlines, laterals and maintenance holes, both structural and non-structural methods and pipe bursting.

- QA/QC – field and test coupons, epoxy resin mixtures, etc.
Effective management of our municipal infrastructure is an essential element of maintaining the long-term viability of our Cities and Towns. Sewer and water assets have been neglected and municipal governments have accrued significant liabilities. Collectively we must clearly identify a strategy for ensuring that these critical assets are maintained to guarantee effective long-term service. Implementation of effective asset management requires agencies to understand their asset inventory and its associated condition. This in turn means that there are vast quantities of data that must be managed and analysed to develop asset management strategies.
Course OutlineThe Data Management course will provide in-depth knowledge of computerized systems available for the storage, management and analysis of asset attribute and condition data as it relates to underground infrastructure. In addition the course will explore future advances in the information technology field. The course gives the civil infrastructure professional a comprehensive foundation and skills relating to:

- Statistical Analysis Tools
- Asset Management Systems
- Simulation and Modelling
As a result of lower reconstruction costs, shorter construction periods, and lower social costs due to reduced traffic delays, trenchless construction methods are rapidly becoming an economically viable alternative to conventional open-cut construction. The use of trenchless construction methods has also been shown to significantly increase pavement life and reduce pavement maintenance and rehabilitation costs.
Course OutlineAs one of the core courses in the epCIP program, the Trenchless Construction course will provide in-depth knowledge of trenchless construction methods used to install new underground infrastructure. The course gives the civil infrastructure professional a comprehensive foundation of knowledge and skills relating to:
- Method selection – trenchless vs open-cut, direct and social costs and environmental benefits.
- Design methods and considerations – site investigation, impact assessment on utilities, risk assessment, life cycle costing, structural designs and services/connections
- Construction - site preparation, traffic planning, specifications, quality assurance and quality control.
- Access point construction – vacuum extraction and open-cut.
- Mainline and lateral trenchless construction – moling, pipe ramming, auger boring, pipe jacking, microtunnelling, and horizontal directional drilling.
Infrastructure professionals dealing with the rehabilitation of municipal infrastructure are faced with the need to upgrade sewer and watermain networks in a cost effective and timely manner that minimizes social and environmental impacts. In urban areas this need has been addressed through the use of trenchless construction and rehabilitation methods. For practitioners who specify trenchless methods, knowledge of current and developing technology is essential.
Course OutlineThe Design Methods course builds on the foundation of trenchless construction and rehabilitation knowledge and focuses on the details of trenchless pipe design. This course gives the infrastructure professional a comprehensive foundation and skills relating to the design of:
- Gravity and pressure systems - structural and non-structural design methods for flexible and rigid liners.
- New pipelines installed using horizontal directional drilling (HDD), pipebursting, microtunnelling, auger boring, pipe jacking or pipe ramming.
Contract Administration and Construction Supervision
As municipalities and other governmental agencies under increasing fiscal pressures consider the use of trenchless technologies, questions arise concerning “the outside forces” that cause project failures. The majority of the No-Dig (trenchless) systems/methods available on the market today have been in use for a number of years and personnel using these technologies are well trained in their application. However, when project failures occur they are often due to inadequate investigation, contract specifications, administration and supervision, rather than the failure of the product or method used. A successful construction or rehabilitation project is one in which the owner has a well written specification, the method proposed is the right solution and the contractor has clear direction to perform the work properly.
Course OutlineThe Contract Administration and Construction Supervision course will provide an in-depth overview of the various administration and inspection techniques currently used in underground infrastructure construction and rehabilitation. The course gives the civil infrastructure professional a comprehensive foundation and skills relating to:
- Contract law and case studies
- General contract specifications – for pre-qualification, bonding, insurance, commencement and completion, prescriptive and performance specifications, liquidated damages, tendering and awards, health and safety, and risk mitigation.
- Construction and rehabilitation specifications - for bypassing flows, design criteria, traffic control, materials acceptance, warranties, social and environmental impacts.
- Administration techniques – pre-construction meetings, commencement letters, public relations, progress payments, holdback release, conflict resolutions and claims.
- Site inspection techniques – daily reports and inspection staff knowledge.
- QA/QC specifications – material testing for conformance.
Life Cycle Cost Analysis and Asset Management
Municipalities, government agencies and their consultants are under increasing pressure to establish life cycle cost analysis tools and asset management strategies. The selection of the best materials, construction or rehabilitation techniques require knowledge of the factors that impact their life cycle performance. Effective asset management programs must be based on sound baseline information and how the assets perform in the short and long-term. This will ensure that available financial resources will be applied to critical assets at the optimal time.
Course OutlineThe Life Cycle Cost Analysis and Asset Management course provides in-depth knowledge of the essentials processes and techniques required to perform life cycle cost analyses and establish an asset management program. The course will give the infrastructure professional a comprehensive knowledge and skills relating to:

- Deterioration models
- Performance monitoring
- Economics analyses
- Business process modelling
Asset Inventory and Condition Assessment
Effective management of our municipal infrastructure is an essential element of maintaining the long-term viability of our Cities and Towns. Nowhere is the task of providing long-term sustainable infrastructure more challenging than for existing sewer and water networks. These assets have often been neglected and our municipal governments have accrued significant liabilities. Collectively we must now clearly identify a strategy for ensuring that these valuable assets are maintained to guarantee effective long-term service. Before we can embark upon the asset management process we must have a sound understanding of the extent and condition of our sewer and water inventory.
Course OutlineThe Asset Inventory and Condition Assessment course will provide an in-depth overview of the many techniques that are currently available for identifying asset location and collection of condition data as it relates to sewer and water networks. In addition the course will explore some advanced techniques that are available but which have not seen broad use in the industry as a whole.
