These guidelines may also be stipulated for use for projects not undertaken directly by the Department but where the funding agency (whole or partial funding) is Transportation and Economic Corridors (TEC). See ‘Appendix A: General Engineering Processes’, for an overview of engineering processes. Should a discrepancy exist between this document and the documents prepared specifically for a project, for example the Terms of Reference for a project, the latter shall take precedence. Standards, guidelines, legislation, regulations, specifications and engineering practices evolve over time, and it is therefore not practical to expect all the contents of this document and the documents referenced to be up-to-date. The Consultant is responsible for using current standards, design codes, and guidelines and for ensuring that all current legislation and regulations are followed. A list of current Federal and Alberta Provincial legislation and regulations that are relevant to highway planning, preliminary engineering, design, construction, and operations is contained on the Department website. This list is not all-inclusive. In the event of discrepancies, the hierarchy of documents shall be as follows, in descending order: 1. Legislation and Regulations 2. Consulting Services Contract 3. Engineering Technical Standards, Warrants, and Processes 4. ‘Engineering Consultant Guidelines for Highway, Bridge, and Water Projects’ See ‘Section 1.1.1: Definitions’ for more information. The Prime Consultant retained by the Department is responsible for the professional liability of all work performed under their Contract, including work by any Sub-Consultant. The checking of the Consultant’s or Sub-Consultant’s work by the Department or the signing of drawings by Department staff does not relieve the Consultant from any responsibility for the work. Therefore, these guidelines will generally use the terminology of “acceptance” rather than “approval” when referring to engineering Professional Work Products submitted to the Department by the Consultant. The purpose of this manual is as follows: To outline the Department’s expectations for the provision of engineering services for the planning, design, and tendering of all provincial highway, bridge, and water management projects where a consultant is hired directly by the Department. To ensure uniformity and consistency in the provisions of these services to the Department. To outline specific responsibilities and authorities of the Consultant when providing these services. The Consultant’s obligations are detailed in the Consulting Services Contract and Construction Contract documents. This manual outlines the deliverables and standards established by the Department which will typically fulfil the consultant’s obligations and ensure that Department requirements are met in the desired manner. This manual does not provide a complete record of all the processes, responsibilities and authorities of the Consultant and the Department in managing the delivery of a department construction contract. Other documents or manuals which must be considered include but are not limited to the following: ‘Engineering Consultant Guidelines for Highway and Bridge Projects – Volume 2 – Construction Contract Administration’ This document provides guidelines covering the post-tender period. ‘Traffic Accommodation in Work Zones Manual’ This document provides information and minimum standards for the provision of traffic accommodation through work zones on highways and bridges in Alberta. ECG Vol. 1 Section 1: General | Rev. 2023 1 Classification: Public The authorities, responsibilities, and processes contained in all these manuals are based on the Department’s policy statements, authorities matrix, contract specifications, and contracts for engineering consultant services. Updates or revisions to existing contract specifications, the terms of the contract, policy statements or the authorities matrix may affect these processes, responsibilities, and authorities. In the event of any such changes which significantly affect the contents of these manuals, users will be advised accordingly. This manual is not intended to replace or modify the contents of the Department’s construction contracts or engineering consultant contracts. If a conflict or ambiguity exists between this manual and the Consulting Services Contract, the user shall contact the Project Administrator for clarification. If the user notices any omissions, obvious errors, or recommendations for future updates, the user should forward to [email protected]. 1.1.1 Definitions The following words, when used in this document, shall have the meaning as defined below: Alberta Land Surveyor A person or corporation registered to perform land surveys in the Province of Alberta. Approval The subject work shall be “approved” by the Department for matters relating to things such as Department policy, funding, contract extensions or over-runs, right-of-way purchase, or Contract Design Change Proposals. The Department will also review and approve Design Exceptions as required. See ‘Section 1.6.1: General’ for more details. Bridge Assessment A technical review of bridge condition, functionality controlling issues, and technical parameters with respect to the crossing and roadway approaches. A key objective is to identify optimum strategies for preservation, rehabilitation or potential reconstruction of the crossing over the life cycle of the structure. See ‘Section 11: Bridges’ for more details. Bridge Conceptual Design An engineering process for bridges undertaken prior to the structural design phase including but not limited to bridge assessment, functional planning, geometric design, hydro- technical design, site location and survey, environmental determinations, preliminary geotechnical investigation, and development of optimized concepts for advancement to structural design. Bridge Structures Consist of: Standard Bridge: Any bridge built using the Department’s Standard Bridge Design Drawings and guidelines. The Department standard bridge design drawings include the SL, SLW and SLC bridge types. Standard Bridge-Sized Culvert: Culvert with a diameter (or summation of diameters) greater than 1500 mm and less than 4500 mm. Major Bridge: All bridge structures not included within the definitions of Standard Bridge or Standard Bridge Sized Culvert. These can include Major Bridge-Sized Culverts, or complex buried structures such as open bottomed culverts. Major bridges are typically built from site-specific drawings but can also be built from standard girder drawings with engineered modifications. Typically, Major Bridges are river crossings, highway interchanges, or railway crossings. ECG Vol. 1 Section 1: General | Rev. 2023 2 Classification: Public Major Bridge-Sized Culvert: Bridge Sized Culvert with diameters (or summation of diameters) of 4500 mm or greater, or structures of lesser diameter having complex site restraints or specialized engineering requirements.
