Review Quiz 1 basic construction management Flashcards
1
Q
what does CM do as a specific delivery method?
A
- Management services are provided to owner before construction or contractor hired
- CM becomes part of team early design phase, assists owner throughout entire design process
2
Q
What are the two types of CM delivery
A
- Agency CM (without risk)
- At risk CM
3
Q
What is an Agency CM
A
- CM hired by owner to oversee construction process but “does not use his own crews for labour and not financially responsible for construction costs”
- hired early in the process to provide expertise
- At completion of design CM co-ordinates hiring of separate GC who will complete physical work/hire subs
- CM manages GC
4
Q
Advantages of Agency CM
A
- Construction expertise early in process
- Allows for fast tracking / or sequential
- Cost benefit of competitive bidding for construction work
5
Q
Disadvantages of Agency CM
A
- Requires high owner input & level of sophistication
- Only suitable for commercial or large projects that would benefit from increased levels of management
6
Q
What is at risk CM?
A
- Similar to Agency CM acting as a consultant to the owner early in process but then acts as equivalent of the GC during construction process
- CM carries some risk bc he provides owner with price guarantee for construction work
7
Q
What is fast track: Concurrent design & construction?
A
- Construction begins without owner having a complete design & detailed and complete estimate
8
Q
What is the risk of fast track
A
- If construction begins and design problems occur at later stage of project, forcing budget change, the owner at that point is committed to more than simple redesign
- good communication between designer and CM is essential as often working on concurrent tasks that must be coordinated
- Designer’s design schedule must be precisely tied to the bid and award of each work package & the detailed construction schedule
- difficult for owner to know real cost of project before construction begins
9
Q
What is the project chronology
A
- precon
- procurement
- construction
- project closeout
10
Q
stages of preconstruction
A
- conceptual planning
- schematic design
- design development
- contract documents
Bidding & award also preconstruction but are discussed under procurement
11
Q
what is the general role of CM during preconstruction
A
- requires continuous owner involvement and interaction as ideas and requires of owner must be clearly translated into contract documents
- supports design process, judges design for constructability, look for ways of reducing cost, prepares for construction & provides competent cost and schedule information
12
Q
owners role in conceptual planning?
A
- hires designer and CM
- selects project site
- establishes conceptual estimate, schedule and program
13
Q
what is schematic design
A
- completion of this phase represents approx. 30% design completion
- design team investigates alternate design solutions and alternate materials and systems, as well as supporting value engineering
14
Q
what happens to schematic design if the CM team decides to tighten schedule?
A
it impacts the designer
15
Q
what happens during schematic design of the designer specifies a specific material?
A
impacts the CM
16
Q
what happens during the design development?
A
- design team evaluates and selects all major systems and components of the project
- evaluate and finalization of all the arch components and project systems
- concurrently project budget and schedule continue to be monitored
- CM evaluates potential contractors and prepares to secure necessary permits
- design firm recommends project systems
- owner decides whether system is acceptable to end user
- CM evaluates cost and schedule implications
- continued estimating and scheduling critical to detecting a design in excess of bidget and to ensure schedule continuity
- preferable to forced redesign when bids have been received and they all exceed budgets
- forced redesign and rebid leads to higher cost and longer duration
17
Q
what happens at the end of the design phase?
A
- design 60% complete and should have good system definition
- most of the project should be quantified and actual unit prices developed
- a detailed network schedule should be in progress and necessary permits identified and scheduled
- all key subcontractors should be identified and involved in the estimating, scheduling, and design process as necessary
18
Q
what happens during contract documents phase?
A
- final prep of documents necessary to define each of the bid packages
- preparation of the technical documents. drawings and specifications and all other necessary supporting documentation
- Fast - track - coordination required between designer and CM as bid packages go out to bid
- Master schedule for the project becomes important during this phase, since designers completion of technical requirements for each bid package needs to be coordinated with advertising/bidding out of the work packages to qualified contractors followed by start of construction
- before going out to bid, contract documents need to be reviewed by CM last chance to catch/correct any discrepancies
- as contract documents near completion, CM prepares complete/detailed estimate (owners estimate, fair cost estimate)
19
Q
How can a project be put out to bid?
A
- bid package by bid package (phased construction)
- done in total with a single contractor bidding on entire project
- final estimate and schedule & an integrated cash flow analysis are completed & used to manage the remainder of the project.
19
Q
What are some important things regarding the owners estimate?
A
- defines the fair cost giving owner a yardstick with which to compare contractor bids
- carefully reviewing the estimate provides an excellent opportunity for the owner/CM team to prepare for the construction phase. Review may lead to addenda being published
- provides owners with final accurate cost info - projects owners cash needs on day to day basis when integrated with the finalized network schedule
