Design award build delivery method
Most common Arch designs the documents Documents used for costing and award Can be a competitive bid or a negotiation with one GC Simple method as roles are well defined
Fast track delivery method
Used when overall time for design and construction is compressed
Design process over laps the construction
With this type, the owner may want to use a CM (3rd party advises on constructibility and cost during design
Design build delivery method
Owner contracts with one entity for the design and construction of the project
Owner advantages:
Single source of responsibility and administration
Fixed price
Total time of design and construction is less over traditional methods
Used by experienced owners with construction and have a detailed set of requirements
CM as an independent advisor definition
Document used…. AIA A232
General conditions of the construction contract for construction, construction manager as advisor addition
Advantages of using a CM
Early advise on constructibility
Early cost estimating, project scheduling, professional management of multiple contracts or fast track, and can be a guaranteed price and completion date
Disadvantages of a CM contract
Extra cost
Complicated management structure with more than one person on the design team
Competitive bidding among general contractors is lost
3 common methods for establishing the project cost under a CM
- Fixed price method or stipulated sum (lump sum)… Set price with no cost sharing of savings
- guaranteed maximum price (GMP)… Set price but owner receives cost savings
- Cost plus fee method …. Owner pays actual cost of construction plus indirect cost plus a fee that is agreed upon before construction begins
The prime contract
The relationship the owner has with the contractor or contractors
Most often a single prime contract
Advantage: single source of responsibility also easier for the arch to administer
Multiple prime contract
Major portions of the work are contracted with the owner …. M E P
Specialty contracts favor this
More difficult for the arch to manage
What are 3 common project delivery methods
Design bid build
Design build
Construction manager at risk
Contract documents consist of
Front end documents
Specifications
Drawings
Design build disadvantages
Owner does not have much control over design once the contract is signed
Disagreements about design and project item inclusion can occur
Quality of materials and methods are determined by the design build firm not owner
To avoid material quality issues, the owner needs a specific set of performance requirements
