CM 102 Chapter 9-13

Three fundamental objectives of a quality management plan

1)Do right FIRST time (know standards) 2)PREVENT things from going wrong (preparatory inspect) 3)IMPROVE the process (Total quality management Program)

Project Control cycle (DEM IEM D)

1. DEVELOP the project plan 2. Establish the project BENCHMARKS 3. MONITOR the project performance 4. identify performance DEVIATIONS 5. evaluate CORRECTIVE options 6. Make ADJUSTMENTS as needed 7. DOCUMENT, report, and evaluate results

Four primary components of an effective safety management plan

1. Management commitment 2. Job site analysis 3. Hazard prevention and control 4. Safety and health training

Precedence Diagram

A graphic presentation of a schedule depicting project activities on a node with an arrow that depicts the dependencies that exist between the activities

Special-purpose schedules

Activities scheduled to SUPPORT the work. ex delivery schedules.

Two techniques to create a network diagram

Activity on the arrow network diagram and activity on the node network diagram. Node example:

What decisions might be made by a contractor during the prebid stage in assessing the risk in bidding a particular project

Add contingency, joint venture, or reject the project

BIM

Building Information Modeling: 3-D model

Differences between BIM and 3D CAD

CAD engine uses a coordinate-based geometry ("dumb graphic") BIM uses a parametric change engine which automatically coordinates changes everywhere in the model

Preparatory insepections

Checks progress to make sure everything is ready for the next stage of construction

Crashing a schedule

Compressing the overall schedule,

Look-ahead schedule (Short-interval schedule)

Created by superintendents and foremen to coordinate and manage work within a short period of time

Quantifying Risks

Determining Probability- Impact potential

What is used to establish benchmarks in the project control cycle

Estimates and Schedules

four primary causes of job site accidents

Falls, struck by materials, crushed, electrical shocks

Summary-Schedule

Group activities under broader headings. ex site work, foundation. etc.

What is Material Safety Data Sheet?

It is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity,health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures.

Construction

Labor: availability, quality Site conditions Site access

Which federal agency is responsible for establishing and enforcing safety standards for construction

Occupational Safety and Health Administration (OSHA)

What are the mechanisms of a Quality Control program?

PLANS AND SPECS_ Submittals, mock-ups, shop drawings, testing standards, independent testing and inspections, code inspections

Identify the policies/procedure of a Quality Assurance program

POLICIES AND PROCEDURES_Hiring practice, training programs, safety Subcontracting practices, procurement methods, employee incentives

Forecasts

Periodic prediction stated in reports as the final cost and schedule outcomes, while the work is still going on

Design

Poor quality or inadequate bid documents,

Two factors to determine the risk rating when quantifying risk

Probability and Impact potential

Three different types of activites that are included in a typical schedule

Production, Procurement, and administrative

Difference between Quality Control and Quality Assurance

QC: at project level QA: at a process level

Gantt Chart

Uses bars to show length of each activity

Factors impacting project performance

Weather, Workforce quality, Supervision quality, Sequence of work, Change orders, Overcrowding, Defective materials, Tools inadequate, Deliveries late

Escalation Clause

a clause in a contract that allows for an increase or a decrease in wages or prices under certain conditions

Contingency

a provision ($$) for an unforeseen event or circumstance

critical path

activites that must stay on track in order to meet the planned schedule

Float (slack)

amount of time an activity that can be delayed before it impacts the project's completion (float calculating)

Financing

cash flow, limited credit, owners finances

Political/regulatory

changes in a law, changes in taxes

Administrative activites

contract administrative- ex. permitting, submitting, inspections, testing.

Prebid

contract requirements, size and location, schedules

5D

cost/estimating

Risk avoidance

don't take project to begin with

Early Start

earliest possible time that an activity can start (forward pass calculating)

Early Finish

earliest time an activity can finish, given its allocated duration (backward pass calculating)

Environmental

environmental permits, hazardous materials or site contamination, endangered species

Latent design defect

hidden flaw in a design, workmanship or a product that is reveal after completeion. i.e. a leak

Zero-punch list

inspecting work as it progresses (vs at end)

Late Start

latest activity can start w/o delay (forward pass calculating)

Late Finish

latest time this activity can finish without delaying the project's completion (backward pass calculating)

Risk transfer

leave it to the experts

Clash detection

like a "spell check" for BIM

Preparatory inspection

make sure everything is ready for the next phase of construction

Detailed schedule

minor work activities broken down to smaller tasks- DETAILED

Procurement activites

obtaining materials and equipment for project

Fundamental stages involved in creating a precedence diagram schedule

planning, sequencing, and scheduling

What are the various types of project risks?

prebid - design - construction- political/regulatory - financing- environmental-

Risk abatement

provide alternative or reduce risk, experience helps you know what can go wrong

Field observation reports

report used to track questionable quality and safety performance

Risk retention

retain reserve fund to offset risk or self perform work

What are the different types of risk mitigation strategies

retention, avoidance, abatement, transfer, allocation

Risk allocation

sharing risk with other parties, joint venture

Production activites

tasks associated with physical building of project
