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
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
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
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,
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
Design-Build Services Contract
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
200 of the CDBI Practice Manual is part of a series
of guides designed to assist Owners and Design‑Builders to understand the
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.
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
(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
Proposal security (submittal
Pre-proposal conference and
Design-Build proposal protocol and schedule;
Technical exhibits required
with the proposal;
Proposal form (instructions for
Submissions of proposals;
Opening of proposals and

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
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.
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:
Construction industry; and
Essential elements of a good conceptual
Understanding of the project
Take-off or quantity survey;
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.
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.
