Construction Contracts, Specifications, and Execution Phase Issues

Vocabulary flashcards covering construction contract types, legal principles, specifications, and project management issues during the execution phase.

Acceptance Period

The specified timeframe during which a submitted bid remains valid and binding on the contractor, typically lasting $60\text{ days}$ after closing, prior to which bids may be withdrawn or corrected.

Contract Agreement

The formal legal document binding the owner and contractor that integrates drawings, general and supplementary conditions, technical specifications, and addenda defining the scope of work.

Time Extensions

Contractual provisions allowing the original construction period duration to be extended for project delays that are not attributable to the contractor's fault.

Change Orders

Formal modifications to the original contract documents or project scope, governed by procedures established in the general conditions.

Changed Conditions

Contractor claims arising when actual physical site conditions encountered differ from those represented in contract documents or present unknown and unusual conditions.

Value Engineering

A mandatory incentive procedure encouraging contractors to propose innovative design or material modifications that lower costs while maintaining full required functionality.

Suspension, Delay, or Interruption

A directive from the owner or contracting officer temporarily halting all or part of the work, which may entitle the contractor to additional costs for demobilization, remobilization, and price escalation.

Liquidated Damages

An agreed monetary penalty paid by the contractor to the owner for each calendar day of unexcused delay beyond the completion date, assessed at $1/10$ of $1\%$ per day up to a maximum cap of $10\%$ of the total contract price.

Progress Payment

Regular interim compensation paid to the contractor covering verified direct expenditures and fee markups for portions of work completed during a billing period.

Retainage

A specific percentage of earned progress payments withheld by the owner to incentivize the contractor to complete all contractual obligations satisfactorily.

Progress Reporting

The requirement for contractors to submit and continuously update construction progress charts comparing planned schedule metrics against actual completion percentage.

ACCEPTANCE AND FINAL PAYMENT

The formal project closeout completed through a joint inspection between the owner's representative and contractor, using a punch list of remaining deficiencies to finalize work and release final payments.

contract

An agreement of at least two parties (owner

and contractor) with purpose of creating

legal obligation between the parties and

capable of being enforced by court law.

Without a contract, technical requirements

lack enforceability

Elements of an Enforceable Contract

The core legal components necessary for legal enforceability: Offer, Acceptance, Consideration, Intent to Create Legal Relations, Legal Capacity, and Purpose, represented by $\text{OFFER} + \text{ACCEPTANCE} + \text{CONSIDERATION} = \text{CONTRACT}$.

Role of Engineers in Contracts

A dual capacity serving as project designer and contract administrator representing the owner, tasked with interpreting technical specifications, certifying payments, and determining contract compliance.

Lump Sum / Fixed Price Contract

A contract model where the contractor agrees to complete all construction tasks according to plans and specifications for a single predetermined total price.

Cost Plus a Fixed Fee (CPFF)

A cost-reimbursement contract where the owner pays all direct job costs for materials, labor, and equipment plus a negotiated fixed fee sum.

Cost Plus a Percentage of Cost (CPPC)

A contract type in which the contractor receives full reimbursement of direct construction costs plus a flat percentage fee based on those incurred costs.

Incentive Contract

A contract structured around a target cost estimate where the contractor retains a portion of cost savings if finished below target, or incurs a fee reduction if costs exceed target.

Design-Build Contract

A delivery method where the owner enters into a single contract with one party to handle both architectural/engineering design and construction execution.

Integrated Project Delivery (IPD)

A collaborative workflow contract aligning stakeholders, systems, and practices to optimize project performance and reduce overall risk across design and construction.

Time and Materials Contract

An agreement where compensation is based on actual labor time spent and materials used, suitable for projects with undefined or evolving scopes.

Unit Price Contract

A contract where total payment depends on multiplying fixed unit rates by the actual measured quantities of work items completed, common in heavy civil construction.

Guaranteed Maximum Price (GMP)

A cost-reimbursement contract capping total owner payments at a fixed maximum limit, requiring the contractor to absorb any cost overruns.

Legal Documents Section

The specification division containing administrative and bidding items such as advertisements for bids, instructions to bidders, agreement forms, and legal performance bond forms.

Condition Section

The specification division defining the legal contractual framework, outlining specific rights, responsibilities, and liabilities of all project participants.

Technical Description Section

The specification division defining specific materials, equipment standards, quality requirements, testing protocols, and construction methods across trade divisions.

Performance Specifications

Methodological specifications specifying required end outcomes and operational standards without prescribing exact materials or construction techniques.

Prescriptive Specifications

Methodological specifications detailing step-by-step instructions on materials, exact dimensions, and construction methods required.

Proprietary Specifications

Specifications requiring the exact use of specific manufacturer brand names, model numbers, or proprietary products.

Supplementary Specifications

Project-specific modifications or additions generated to amend standard or general specifications for unique conditions.

Substantial Completion

The point of progress, defined as $93\%$ completion, where the owner can occupy and utilize the facility while remaining minor works do not impair structural integrity.

Labor Cost Adjustment Formula

The contract formula for price adjustments due to mandatory minimum wage increases: $\text{Adjustment} = \frac{A \times B \times C}{\text{Minimum Wage}}$, where $A$ is the labor portion, $B$ is $70\%$ affected, and $C$ is the balance of remaining work.
