Construction Contracts

and Project Delivery Methods

ACT 380

1

Objective

Exposure to the different types of construction contracts, the number of contracts, the method of contractor selection and the basis for contractor payment.

2

Contract Defined

An agreement between two or more parties representing a promise to be performed for consideration

3

Necessary Parts of a Typical Construction Contract

O Parties identifiedO Parties make promises that constitute

an offerO Both parties sign the contractO Both parties receive consideration:

O Contractor – payment for work doneO Owner – use of the completed project

O Parties of the contract must have the LEGAL AUTHORITY to negotiate a contract

4

Contractual Relationships

O Agreement between the OWNER and CONTRACTOR is the primary construction contract

O There are other contractual relationships which exist

5

Construction Agreement Forms

O Agreement – legal, binding, written document signed by owner & contractor

O Defines the relationships and obligations that exist

O By reference it incorporates ALL OTHER CONTRACT DOCUMENTS

6

Standard FormsO AIA Document A101O EJCDC Document 1910-8-A-1

7

Advantages to Using Standard Agreement Forms—Disadvantages

if Modified Forms UsedO Advantages

O Familiarity of the formsO Legal precedents interpreting the

documentsO Uniformity of terminology

O DisadvantagesO Modifications warrant care that all

references are coordinated (change in one part of the form may require changes in several locations)

O Seek legal counsel8

Conditions of the Contract

O Define basic rights, responsibilities, and relationships of the parties involved in the construction process in greater detail than the agreement

9

Design & Construction Parties

O Owner – may be an individual or an organization; initiates the project and secures funding for the design, construction and operation of the completed project

O Contractor – agrees to build the project; may enter into sub-contracts

O A/E – develops project designs and prepare construction documents; consultants may include: structural, civil, mechanical, electrical, acoustical, & environmental engineers and landscape architects, interior designers, and hardware specialists

10

Methods of Contractor Selection

O Competitive BiddingO Direct Selection

11

Competitive BiddingO Objective is to ensure that the cost of

the project is reasonable and consistent with existing conditions in industry

O Publicly funded projects – owner required to select lowest bidder

O Private projects – owner may also consider the bidders’ qualifications, experience, financial condition, and performance history

12

Direct SelectionO Owner, with advice from the A/E

selects contractor – total price and method of payment is then negotiated

O This method is generally NOT allowed for public projects

13

3 Decisions Made in Determining Kind of

ContractO Number of contractsO Contract typeO Basis of payment

14

Number of ContractsO Single Prime Contract – most

common, uses competitive bidding (pg 3.12; fig 3.3-C) owner has contract w/ A/E & contractor; but A/E & contractor do NOT have contract

O Multiple Prime Contract – Owner divides the work among several contractors & has separate contract w/ each of them. (pg 3.13; fig 3.3-D) [e.g. paving, site work, foundations, landscaping, painting] Often used in FAST TRACK projects when construction on parts of the project is started prior to all of the design elements of the project being completed

15

Project Delivery Method

O Design-Bid-BuildO Design-Negotiate-BuildO Construction ManagementO Design-BuildO Owner-BuildO Construction SubcontractsO Total Project Commissioning

16

Design-Bid-BuildO Traditional method of project deliveryO Typically uses competitive biddingO Considerations

O Project fundingO Owner’s capacityO CostO Extent of workO Time priorities

O See Figure 3.4-A on page 3.16

17

Design-Negotiate-Build

O Similar to the Design-Bid-Build contract but only ONE contractor involved in developing costs and negotiating a contract to construct the project

O Primary considerations are construction excellence and time (project costs not subject to competitive bidding process)

O See figure 3.4-B on page 3.1918

Construction Management

O May have either single or multiple prime contracts

O Construction manager is employed by the owner to oversee and administer the project (may or may not actually perform any of the construction work)

O See pg 3.24; figs. 3.4-C & 3.4-D

19

Project ManagementO Similar to construction management

but also includes coordination of the design & planning stages of the project

O Large projects overseas have been successful using this

O Projects involving multiple structures & extensive site improvements often require this type of supervision; complex projects such as industrial & process engineering plants use this type of contract

20

Design-BuildO Owner contracts w/ a single entity to

design as well as build the projectO Turnkey – an extended design-build

contract in which the selection, procurement, and installation of all furnishings, furniture, and equipment is also included

O See pg 3.30; fig 3.4-E

21

Owner-BuildO This type of contract is usually seen

with large-scale developers O Only construction contracts needed

are between the owner and various subcontractors

O See pg 3.34; fig. 3.4-F

22

Construction Subcontracts

O Usually involves a contract between the contractor and subcontractors and material suppliers

O May be verbal…best if written

23

Total Project Commissioning

O Defined by ASHRAE as a method to improve the delivery of a process.

O Focus is on QUALITYO Makes sure that all components of a

building are planned, installed, and maintained according to an owner’s requirements

24

3 Types of Basis of Payment

O Stipulated (Lump) SumO Unit PriceO Cost-Plus Fee

25

Stipulated SumO Simplest method usedO States that the contract

requirements will be completed for a given amount of money

26

Unit PriceO Used when the extent of work or

actual quantities can not be determined when bids are made (earthwork is such an example)

O Many civil engineering projects use unit price type of payment

O With unit price, the owner pays for exactly what is documented as done after the work has been completed

27

Cost-Plus FeeO Contractor paid for actual cost of labor

PLUS a fee for overhead and profitO Fee may be a percentage of the labor &

material cost or a fixed amountO Cost-Plus Fee agreements may also

include incentives for early completionO It is reasonable for the owner to require

a guaranteed maximum price to ensure that the total project cost will not exceed a given amount
