Design And Build Contract Aims Construction Essay

Published: Last Edited:

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

In the following discussion we shall attempt to describe these documents and explain how they are prepared while focusing on the significance of these documents for the contract.

The standard design and build contract or the turn key contacting system is a method of procurement in which the contractor provides both the services of designing and building the project under one contract unlike traditional procurement method in which the owner's designers had to provide the designing services to the contractor.

This delivery system is gaining popularity in the industry because of its inherent advantages such as reduction in delivery time because of simultaneous designing and building by the single contractor and lessening of risks as contractor is responsible for design as well as construction; besides, providing flexibility to the contract based on the needs of the work and the requirements of the owner/employer.

This successful and innovative approach seems to have found its motivation in "Master Builder" approach used in almost all pre modern construction projects wherein one Chief Architect- the Master Builder- was In charge of all the aspects of the project from onset to completion.

Design and build has been recognized by the industry as well as JCT as standard form of contract as JCT d&b98 and 2005

1.1 Overview

Design and build contract aims at optimizing the traditional method of procurement through bringing together the design,permit and construction works. Minimizing the delivery schedule is achieved by doing the different aspects of the construction activity such as design and construction simultaneously in a overlapping the traditional method construction activity has to wait while the design is underway but here construction can start while the structure is dtill being designed.

As the name suggests the key element of this procurement is that in this delivery system -single organization is responsible for both the design and construction of the project there by aiming at achieving the optimum results through co-operation in an collaborative environment.

Flexible nature of the method allows for both the contractors or the design firm to work in a design build environment. Hence the nomenclature-"Contractor led Design-Build" and the "Design led Design -Build" respectively. Although the organization employed for design build may handle both aspects of-design and construction in house by hiring the required professionals in respective departments, but it is rarely the case in either case the organization prefers to subcontract the other aspect to the concerned professionals.

Hence the process is very simple the employer employs single organization for both design and construction through a single contract. This basic and simple difference saves money and time by allowing the designers and builders to work simultaneously in an overlapping fashion under one organization in an environment of team work and collaboration .

In a standard D&B contract the process begins with the request for proposal by the employer, the document called ER which has been described below, the contractor offers the proposal called CP and the contractor also prepares another document called CSA giving the general break up of component costs.

2.0 Major documents:

All these main documents are used in conjunction with standard DB Contract namely:

Employer's Requirement

Contractor's Proposal and

Contract Sum Analysis

Are described below explaining how they are prepared and their significance to the contract:-

2.1 Employers requirement:

Single point responsibility is one of the key features responsible for the popularity of Design and Build contracts as the litigation is being involved more and more these days in construction projects like all other businesses today the extent of contractor's liability can be well defined through sensible drafting of the contract document.

The document popularly called "employers requirement" acquires prime importance in the design and build contract as this is the basic document that describes the project. It provides the outline design of the project. In a design build delivery system employer has little control over the detail design as it evolves during construction this document can be used to employers advantage by providing as much initial and fundamental detail as possible within this document.(as can be seen in the example Annex-1 A-where in complete detail of requirements have been provided) This is basically an outline design or the details of requirements and expectations of the employer from the project asking the contractor to propose a design to meet such requirements/expectations hence the name.

As can be seen in the example Employer's Requirement provided at Appendix-1A where in detailed requirements alomng with other terms and conditions have been included very precisely. .

2.1.1 How to Prepare ER:

As stated before it is wise and in the interest of the employer to invest some time and resources in developing this document so that it can used to full advantage of the owner. Hence it is advisable to seek the professional help of project managers, designers and legal advisors to develop ER in consultation with the employer, considering the size and complexity of the project.

Although the ER is drafted for individual projects but it should essentially contain following items, where applicable, in order to make it more effective and serve the purpose the document is intended to serve.

Project Over view

General background

Detailed site including the boundaries

Kind and number of structures

Purposes for which the structure id to be used

Detailed scope of work

Design and structural requirements to meet

Legal and statutory requirements to meet

Health and safety standards and compliance

Specific/special requirements-

Mechanical performance specification

Electrical performance specification

Acoustic requirements

Voice and data requirements

Audio-visual specification

Wall and floor finishing schedules

Furniture specification and space standards

Density and mix of dwelling and any height limitations.

Concept and design

Employers requirements regarding submission/proposal of contractor's design/drawing

Schematic lay out/ drawings

Drawing, plans, sections,elevations,details,scale etc.

Terms and conditions

whether stage or periodic payment is to be made

method of fixing the date of completion

Ttente base date

Whether any limit on contractor's liability if limit, the extent of limit

the detailed manner in which contract particulars are to be completed

Mode of payment whether advance payment will be made or the bond is required etc.

what shall be method of measurement

managing clients and third pary liaison

details of any constraints-legal or technical

access restrictions

availability of public utilities

responsibilities and authority of the client's agent/agents

proposed form of building contract and completed appendices

managing the briefing and scope,definition process,appointing design consultants,

implementing change control

information to be included for the contract

proposed tender and construction programme

form of tender

as can be seen in the Annexed Real Employer's Requirement-as an example you can see that most of the elements listed here have been included in the example document in order to avoid confusion and disputes

in which as much detail as applicable/possible have been included including the terms and conditions, payment schedule, design requirements etc.

2.1.2 Significance of ER to the contract:

Significant considerations and decisions need to be made before contracting a project; employer may not have complete knowledge about all these considerations for various reasons such as their technical nature. All such major considerations can have significant impact on the project. Therefore, the need arises to afford sufficient time and resources to understand and make the contractor understand-what precise services and outcomes the employer expects from the contractor.

As discussed before litigations, which are main hurdles for any industry have increased many fold in recent years. Lack of clear understanding between the parties-about what is required is one of the primary reasons for disputes leading to unwanted litigation, as litigation can prove costly for both the parties resulting in waste of time and resources, jeopardizing the completion of project it self in many instances.

If ER have been unambiguously set out on the onset, it will most certainly, help to curb such disputes arising out of confusion regarding-what needs to be rpovied by the contractor.

2.2 Contractor's proposal

Contract proposal is a document prepared in conjunction with design and build procurement developed and prepared by the contractor in response to the ER -describing in detail how the contractor proposes to meet the requirements of the employer answering each employers requirement in ideal situations. This document outlines the key elements of the terms of the project giving details of the services the contractor proposes to offer and the manner in which the services shall be delivered covering the details of time and resources involved.

As the contractor's proposal is in fact an answer to Employees Requirement, the proposal will be detailed and inclusive if the ER is detailed and specific so if the ER is vague the proposal is bound to leave many loose ends which may lead to confusion. Consistency of the two documents is significant, hence it is advisable to discuss with the employer and ask the Employer to clarify and amend, if required, those elements which are not well defined, before the contract documents are signed in order to avoid any confusion and misconceptions that may lead to disputes and/or litigation.

It is also not advisable to include any provisional sums if not requested by the employer; and if the contractor wishes to include he should attaract the attention of the employer towards them so that they may be included in the requirements before signing the contract.

2.2.1 How to prepare Contractor's proposal

Care should be taken to prepare the CP as this is the document as CP gives you an opportunity to clearly define how you propose to meet the requirements of the employer, how qualified you are to meet the expectations of the client , what alternates you propose/suggest and what are your terms for the contract along with providing you with an opportunity which decides whether you will be awarded the work or not. The document should be drafted after the careful study of the employer's requirement or the request for proposal along with all the information provided which may include project overview, outline or detailed design and the budget the project. It is advisable to include a method statement with the proposal to convince the employer about how you propose to meet his requirements.

The draft will vary for individual projects but it should contain following basic elements;

details of work-it should contain all the details related to work and drawings of the project-including professionals,labour,materials. It should also contain list of contract date and time,plan date,number of addenda and their dates etc.

method of work-it is good to include programme or method statement consisting of detailed specification covering all the work and resources

Contacts-It should include the detail of contacts of both the contractor and the clients including those of architects and other professionals involved,where applicable.

site- contractor is supposed to inspect the site before submitting the proposals and note all existing conditions with reference to the project while making the proposal and generally no allowances for overlooking the conditions shall be made

costs and pricing-it must include-all the costs and pricing including alternates and unit pricing, if applicable.The CP sould also contain the details of the costs of bonds, extra insurance requirements and voluntary alternates the contractor may like to offer.

The contractor should observe due caution with voluntary pricing and value engineering.

The CP presents both the clarification and the qualification of the contractor's scope of work, it is advisable to include-

What the contractor is going to include. This may further include-

All types of materials proposed to be used

All services

What is contained in the labour burden and the inclusion or exclusion of tax

ii. what the contractor is going to exclude

Contractor should be specific about exclusions and should also clearly indicate the services not part of the proposal. He should be cautious as Architects often list the items that are not part of the contractor's trade

iii. What others are going to provide-

it should generally include the items that are to be provided by the client such as-power ,water,roads,adequate lighting, safe work environment and site security etc.

as can be seen in the sample Proposal document annexed as Annex-1B- "Proposal XYZ Roofing" in which un ambiguous details of the work with costs have been included

2.2.2 Significance of the Contractor Proposal to the contract:

A well drafted contractor's proposal not only protects the contractor from the unwanted disputes cropping up later such as disputes regarding quality and cost of materials etc, but it also increases his chances of getting awarded the project, as it is not uncommon in the industry for the employers to invite contractor's proposal from more than one organization and use them as project bids.

As the two documents Employer's Requirement and Contractor's Proposal are complimentary in nature, under typical contract, the employer is required to accept the contractor's proposal as meeting its requirements hence making it mandatory to fulfill legal requirement of the contract.Hence the Contractor's proposal gives an opportunity to plug any gaps in Employers Requirement by filling in the missing vital information such as contract data and attaracting the attention of the employer to amend the requirement accordingly before signing the contract. If the vital information is missing in both the documents it is a recipe for disputes. Hence the Contractor's proposal is very significant document in standard DB contract

2.3 Contract Sum Analysis

It is document prepared by the contractor in conjunction with D&B procurement-primarily to enable the agent of the employer to -

assess or value the changes in the ER (variations), contained at the end of the CP and

to value the work in parts or stages or the services.

As the CP essentially mentions the sum contractor needs to carry out the work in response to ER in CP ,under JCT-98(B&D) the contractor proposes a lumpsum amount along with a contract sum analysis to facilitate-agreement to additional costs incurred due to variations in ER.

Essentially, the contractor carries out the job for a fixed stated amount payable by the employer.In standard DB contract there is no provision for re-measurement-but there is a provision for changes in Employer's requirements and variations. Provision of payment may be done either in fixed stages(mile stones) or periodic payments based upon the value of the work completed. Hence the purpose of the Contract Sum Analysis-Break down Analysis of the contract sum is to help in evaluation of variations and changes and also the work completed by the contractor.

Method or formula of valuing design work should essentially be included even if not required by the employer. This may be on hourly basis and proves handy in valuation of changes and also in valuation of design work carried out but aborted later.

Where formula for fluctuations are used the proposal must contain definite and appropriate information to avoid any disputes.


Contract Sum Analysis helps in valuing any additional work/works carried out by the contractor and also the part of the work thereby minimizing the chances of disputes relating to additional or alternate work or any other interim payment hence is an important document along with ER and CP in relation with DB procurement.

CSA-the break down of contract sum- is prepared by the contractor in accordance with the ER but some elements like method of valuation or the formula for fluctuations must be included even if not required by the employer for the sake of clarity and avoiding problems. As we know in DB standard contract there is no provision for re-measurement and only a provision for change and fluctuation hence the the Contractor Sum Analysis is absolutely important for evaluating such changes.

2.3.2 How to prepare and develop

Before developing the CSA the contractor should study the ER carefully as this may, in most cases, specify how the cost should be displayed. So that it is prepared according to the expectations of the client as far as possible.

Form and content of the CSA is not standard hence will vary from contract to contract. However JCT has provided some essential elements which can be used as guideline.

The CSA should normally include;

payment schedule based on (i)milestones and/or (ii)progress

milestones payments means pertaining to (a)time e.g. weekly or monthly or achievement of certain event e.g. Equipment delivered on site. While in progress payment the payment schedule is linked with actual progress of work. Hence it is common practice to include milestone payment schedule with certain rights of the owner to with hold payments or part of the payment in case of large differences between the milestone and actual progress(measured quantity).

Detailed cost and time of staff and labour

Cost of management time

Time and cost of administration

Estimate of reimbursable expenses to be incurred by the contractor

A provision for valuation of changes/variations by milestones/day work should be provided where the valuation by progress/through actual measurement is not feasible, as is provided in JCT 98 (d&b)

It should also include value of adjustment to the contract sum with reference to values.

Essentially, a detailed break down, duly supported by calculations should be provided. To avoid any confusion and ambiguity,unit of measurement, currency you are dealing in and whether the price include VAT or any other applicable taxes should be clearly mentioned. As this form of procurement seems to benefit the employer at the risk of contractor it is a good idea to include a reasonable contingency for any unexpected or miscalculated cost that may arise in due course.


Employer's requirement, Contractors proposal, Contract sum analysis,

The three major documents used in conjunction with a standard Design and Build contract have been discussed in detail explaining their significance in DB procurement and the way they should be prepared. Two main documents viz. ER and the CP have been illustrated with help of real examples

It is concluded from the discussion that these three documents are very important in DB procurement and they are inter linked and inter related, hence should be read with reference to each other. Further it is important to develop and draft them very meticulously to take full advantage, as carefully and sensibly drafted ER, CP& CSA can help in avoiding confusion leading to litigation and other hindrances that may affect the contract.
