Mixed Deck — All CDS Topics Flashcards

How does risk appetite influence management decisions?

Answer: It defines the level of risk an organization is willing to accept in pursuit of objectives

Risk appetite defines acceptable risk levels in pursuit of objectives, guiding decisions about which risks to accept, mitigate, transfer, or avoid.

Under OSHA 1926.858, what is the maximum floor loading permitted for debris accumulation before it must be removed?

Answer: The design load capacity of the floor

OSHA 1926.858 prohibits debris accumulation that exceeds the design load capacity of the floor to prevent structural failure during demolition.

Which confined space classification applies to a basement demolition area with a single ladder entry point and potential for toxic gas accumulation from disturbed materials?

Answer: Permit-required confined space

A space with restricted entry and a recognized serious safety or health hazard, such as toxic gas accumulation, qualifies as a permit-required confined space under OSHA 1910.146.

On a structural drawing, what does a 'match line' indicate?

Answer: The edge of the drawing sheet where the plan continues on another sheet

A match line shows where a plan has been split across multiple sheets; the contractor must align both sheets at that line to see the full picture.

What is risk mitigation?

Answer: Taking actions to reduce the likelihood or impact of identified risks

Risk mitigation involves specific actions to reduce either the likelihood of risk occurrence or its potential impact, bringing residual risk to acceptable levels.

When a structural drawing notes 'REMOVE AND SALVAGE,' what action is required of the demolition crew?

Answer: Carefully remove the element and store it for reuse or owner retention

'Remove and Salvage' means the item must be carefully removed and preserved for reuse, resale, or owner retrieval.

What is the role of environmental impact assessments in demolition planning?

Answer: To ensure compliance with environmental regulations.

Environmental impact assessments (EIAs) are crucial in demolition planning to ensure compliance with environmental regulations and minimize ecological harm. They identify potential environmental risks, such as air and water pollution, noise, and hazardous waste, allowing for the development of mitigation strategies. This proactive approach helps protect natural resources and public health during the demolition process.

In a specification, the term 'Allowance' in the context of demolition work means what?

Answer: A pre-set budget amount included in the contract for undefined or unforeseen work, to be used as directed

An Allowance is a specified dollar amount set aside in the contract for work whose full scope cannot yet be defined, such as unforeseen conditions encountered during demolition.

A demolition drawing revision cloud indicates what to the field supervisor?

Answer: An area of the drawing that has been changed since a prior issued revision

Revision clouds are drawn around any area of a blueprint that has been modified, alerting users to review that section for changes.

When planning equipment requirements for a demolition project, which factor should MOST influence the choice of primary demolition equipment?

Answer: Structural type, material composition, site access constraints, and debris removal method

Equipment selection must match the structural type, materials, site access, and debris handling plan to ensure safe and efficient demolition.

During the demolition of a structure with suspected lead paint, at what airborne lead concentration must a full written compliance program be implemented?

Answer: Above the PEL of 50 μg/m³

OSHA 29 CFR 1926.62 requires a full written compliance program when airborne lead exceeds the PEL of 50 μg/m³ as an 8-hour TWA.

According to OSHA 29 CFR 1926.852, chutes used to remove debris from heights greater than 20 feet must be enclosed and discharge into which type of container?

Answer: An enclosed container with a tight-fitting lid or screen

OSHA 1926.852 requires that high-rise debris chutes discharge into an enclosed container to control dust and prevent debris from scattering at the collection point.

What is earned value management?

Answer: A method to measure project performance by comparing planned versus actual progress and cost

Earned value management integrates scope, schedule, and cost metrics to objectively measure project performance and predict future trends.

What is residual risk?

Answer: The risk remaining after mitigation measures have been applied

Residual risk is what remains after mitigation measures are applied, and it must be accepted, further reduced, or transferred based on organizational risk tolerance.

The ICC/ANSI A117.1 standard becomes relevant in a demolition project context when:

Answer: Temporary accessible routes for the public must be maintained

ICC/ANSI A117.1 accessibility standards apply when temporary pedestrian routes must be maintained near demolition sites, ensuring ADA-compliant access.

During the planning phase of a demolition project, what is the PRIMARY purpose of a pre-demolition survey?

Answer: To identify hazardous materials, structural elements, and site conditions

A pre-demolition survey identifies hazardous materials, structural vulnerabilities, and site conditions that affect safety planning and sequencing.

What is the primary purpose of regulatory compliance in professional practice?

Answer: To protect public safety and ensure minimum standards of care

Regulatory compliance exists primarily to protect public safety by ensuring all practitioners meet minimum standards of competence and ethical conduct.

On a plumbing or mechanical demolition drawing, what does the note 'CAP AND ABANDON' mean?

Answer: Seal the pipe end at the nearest accessible point and leave it in place

'Cap and Abandon' means the pipe is sealed at a specified point and left in place rather than fully removed, reducing demolition scope.

Which document records all approved changes to the original contract scope, schedule, or price?

Answer: Change Order

A change order documents approved modifications to the contract's original scope, schedule, or cost.

A subcontract agreement primarily serves to:

Answer: Document scope and payment terms between the GC and subcontractor

A subcontract agreement establishes the scope, schedule, and payment obligations between the general contractor and each subcontractor.
