BIM to Manage Construction

- Building a project in a virtual world before building it for real -work out many glitches behind a computer as opposed to in the field - link schedule and estimates

Occupational safety and health administration (OSHA)

- Establishes safety standards for construction industry - Enforces standards through inspections at the job site - Fines if regulations are not followed

Primary causes of jobsite accidents

- Falls (33%) - Struck by materials, equipment, or other objects (22%) - Crushed or trapped (18%) - Electrical shocks (17%)

Common products requiring Material Safety Data Sheet MSDS

- Gas and fuel oil - Paints - Adhesives

Risk Quantification

- Likelihood of occurrence? - At what impact? (cost, schedule, etc) - What consequences? (more work, defects, etc)

When overrun occurs a Superintendent and Project Manager can mitigate by?

- Material Price Escalations - Increasing the amount of workforce - Identifying Quantity Errors

for evaluating project performance use *project debriefing*

- Target Goals and achievement - On-site team performance - Owner issues - Designer issues - Quality control issues - Subcontractor performance - Unusual circumstances or conditions

Factors Impacting Project Performance

- Weather conditions - Quality of Workforce - Quality of Supervision - Incorrect sequencing of work - Change orders - Overcrowded Job site - Defective Materials - Inadequate Tools and Equipment

Risk Mitigation

-Anticipate negatives ex. weather, price rise, enviro issues, political fallout, etc - Initiate actions - implement strategies

Detailed Schedules

-Break major activities down into smaller tasks so the overall schedule can be analyzed in greater detail -used at the field office

Why is estimating used in BIM (5D estimating)

-Estimating is the 5D aspect of BIM -makes it easy to conduct take-offs -limits room for errors in take-offs ("take-offs" are quantities of items they will need from blueprints in order to prepare part of the estimate. Examples of possible take offs include the number of light fixtures needed in the building plan)

Summary Schedules

-Group activities under broad headings Ex. mobilization, site work, foundation -most often used for management reports and presentations

Why is scheduling used in BIM? (4D scheduling)

-It adds a fourth dimension to the model -Helps with sequencing of activities -Helps with phasing and coordination -Helps with project logistics (a logistic is a detailed coordination of a complex operation)

How can BIM help with prefabrication?

-Knowing exactly how to prefabricate a piece will help cut down the schedule. -Prefabrication helps to raise the quality and lower costs. prefabricate: manufacture sections of to enable quick or easy assembly on site

How does BIM integrate subcontractors and suppliers?

-Many subs create their own BIM models -Elements contain information on product data, fabrication and installation

programs to aid in scheduling projects:

-Primavera P6 -FastTrack Schedule 9 -TracTime -BuildIt

What are the basics of *clash detection*?

-Show's material conflicts -Problems can be addressed before reaching the field -Saves money and time in rework/redesign.

How can BIM help with Layout and Fieldwork?

-Superintendents can use a model to see where lay-down areas and deliveries would best work with pinpoint accuracy

How is Operations and Maintenance effected by BIM?

-The As-Built is updated continuously during construction and given to building engineer. - BIM can link products & materials to the equipment and maintenance manuals installed

designing in BIM

-allows for what if scenarios in a virtual environment -allows specialty subs to see how their components interact with architectural components

Mini- Schedules

-broken down into even finer detail Ex. showing plumbing, heating, ventilation and air conditioning

Short-Interval Schedules (Look ahead schedules)

-created by superintendents and foremen to manage work over short period of time typically 3 week schedule -acts as work plan for work crews on site

Ways to track Job Performance

-daily field reports -time cards -subcontractor billing statements -delivery tickets -material invoices -equipment time tickets -job logs

AON Network Diagram [A]------------------------------>[B] activity relationship activity

-method of choice for the industry -also called precedence diagramming -Activity is noted on the node and arrows show relationships

The Planning Stage

-read project plans and specs -use WBS to create activity list

Feedback

-used to detect variances btw actual cost, time, and productivity from the estimate and schedule
