The 100 Series of the CDBI Practice Manual is the first of a series of guides designed to assist Owners and Design‑Builders to understand the Design‑Build process.

In the traditional project delivery system the Owner engages an Architect/Engineer to prepare designs and construction documentation, and hires a contractor to build the project. In the Design-Build project delivery system, the Owner contracts with the Design-Builder to provide both design and construction services in one package.

Design-Build is not one-size-fits-all and, in some instances, traditional project delivery systems may offer distinct benefits on certain projects. By carefully weighing all the benefits and disadvantages, Owners can select the method most appropriate to any given project.

This guide also includes a comprehensive list of Design-Build terminology, industry acronyms, benefits of Design-Build and other considerations.

The information contained in Document 110 is intended for use with the CDBI documents published by the CDBI. The best practices and additional considerations contained in the guide are specific to the transportation infrastructure sector.

The transportation sector brings together a number of professional design and construction disciplines in various fields of expertise such as transit, roads, rail, tunnels, bridges, highways, airports, and ports.

There are several key elements common to transportation projects that uniquely impact on CDBI's best practices. These project elements impact project conceptualization and design, the design-build procurement process and the post-award project results.

This guide will discuss three primary sections:

·         Procurement

·         Design-Build Services Contract

·         Project execution

In making these choices, it is critical for an Owner to consider the particulars and circumstances of each project. After thoroughly considering these issues, an Owner should make a strategic decision to take full advantage of the many benefits inherent in the design-build process.

Series 200 of the CDBI Practice Manual is part of a series of guides designed to assist Owners and Design‑Builders to understand the Design‑Build process.

The Design-Build method of project delivery involves a single source for design and construction services. While the Design-Build method may be applied to a wide variety of project types and sizes, this guide is generally more suited to large or complex projects. The Series 200 documents are intended to assist Owners in preparing documents for a Design-Build proposal call, however prospective Design-Builders should also make themselves aware of the content of these documents to understand the Owner's perspective. Design-Builders are advised to refer to Series 300 for best practices in responding to RFQs and RFPs.

Owners must pay particular attention to the early development and finalization of design and construction criteria, as well as to the procedures for selecting the Design-Builders, the design solution, schedules, contract conditions, contract price, methods of delivery and payment, and the best overall proposal.

This guide also includes information on why and how much Owners should pay in honouraria.

CDBI Document 210 is a guide for Owners to develop a Request for Proposal (RFP). It describes the principles and organization of the general requirements contained in a typical RFP.

In addition to a short narrative description of the following subject matters, this guide provides sample optional wording for users to choose from:

INFORMATION TO PROPONENTS

·         Proposal documents (honourarium, purpose, and use);

·         Qualification of Proponents;

·         Examination of the RFP documents and site (Proponent's responsibilities, Owner-provided information);

·         Availability of lands for work;

·         Omissions, interpretations, and addenda;

·         Proposal security (submittal and return);

·         Contract times;

·         Pre-proposal conference and Design-Build proposal protocol and schedule;

·         Technical exhibits required with the proposal;

·         Proposal form (instructions for completion);

·         Submissions of proposals;

·         Opening of proposals and evaluation;

·         Owner's acceptance or rejection of proposals.

PROPOSAL FORM

·         Project identification;

·         Proposal salutation;

·         Proposal obligations and representations;

·         Contract price;

·         Terminology.

SUBMISSION

·         General requirements;

·         Format.

Series 300 of the CDBI is a guide designed to help Design-Builders confidently and professionally respond to Requests for Qualification (RFQ) and Requests for Proposals (RFP).

This guide focuses on the following main points:

·         How to analyze an RFQ to determine whether a response is worthwhile;

·         How to assemble a design-build team and to demonstrate that they are the most capable in performing the work;

·         Key considerations in preparing the submissions; and

·         What to analyze in the owner's statement of requirements.

There are also discussions on the development of proposal designs and response to draw/build proposal calls.

CDBI Document 310 offers guidance to conceptual estimating and shows how it plays a very important role in the Design-Build process.

A conceptual estimate is an assessment of the cost or value of a project based on conceptual design information, including general characteristics such as size, shape, location, material selection, etc., and by necessity must include all items necessary to complete a project, regardless of whether explicitly shown or specified.

This guide explains the factors that influence the cost of a project, and these typically include:

·         Economy;

·         Construction industry; and

·         Building.

Essential elements of a good conceptual estimate include:

·         Understanding of the project intent;

·         Take-off or quantity survey; and

·         Pricing by both subcontractors and sub-consultant design professionals.

There are also discussions on the two conceptual cost methods, single-unit cost method and multiple-unit cost method.

Series 400 of the CDBI Practice Manual is a guide designed to assist Owners and Design‑Builders to understand the Design‑Build process.

There are significant differences between the delivery of Design-Build and traditional design‑bid-build projects. The major difference is that the Design-Builder assumes the traditional roles and responsibilities of the Consultant and Contractor for both design and construction. The Design-Builder undertakes to design and build a project that meets the Owner's statement of requirements.

The key to delivering a successful Design-Build project is for all participants (Owner, Design‑Builder, Consultants, and Contractors) to commit to working together co-operatively for the benefit of the project. It is important that all participants agree to and understand their roles and responsibilities. A co-operative approach reduces decision-making times, administrative costs, and the risk of cost and schedule overruns and disagreements about contract interpretations.

This guide also includes a comprehensive list of Design-Build terminology, information on agreements, schedule & cash flow, payment, changes, dispute resolution, the role of authorities having jurisdiction, and more.
