Project Manual & Specs Flashcards
project manual
a bound book contaiing all the contract and nonctract documents for a construction project, except drawings
includes specificiations
the project manual is divided in 4 major parts
1) bidding requirements
2) parts of the contract
3) the general and supplementary conditions of the contact
4) the technical specifications
what are the contents of bidding requirements in a project manual?
- invitation to bid
- prequalification forms
- instructions to bidders
- information available to bidders
- bid forms
supplements to bid forms include:
- bid security form
- subcontractor list
- subsititution list
what are the contents of contract forms in a project manual?
- agreement (contract between owner and contractor)
- performance bond
- labor and materials [yament bond
- certificates of insurance
- general conditions of the contract (e.g. AIA form 201)
- supplementary conditions
technical specs and drawings are complementary. How so?
- drawings show general configuration and layout of building components, along with general notes to explain graphics
- techincal specs describe the quality of materials and workmanship along with general requirements for the execution of the work, standards, and other items that are more appropriately described in written, rather than graphic, form
what is one method of ensuring that wirtten techincal specifications contain requirements for all the mateirals and construction idicated on the drawings?
-the use of a common checklist between sepc writer and project manager
when there is aconflict between the drawings and the specifications, which is more binding in the case of conflicting information
written specifications
what are the four areas of concern when coordinatin informatioin between drawings and techincal specs?
1) specs should contain all the materials and construction indicated on the drawings
2) the terminology used in both documents should be the same
3) dimensions and thicknesses should only be indicated on one document
4) notes on the drawings should not describe methods of installation or material qualities; these belong in the specs
master specification
- a prewritten test that includes the majority of requirements for a particular specification section
- edited by deleting uneccessary portions, and adding particular information related to project at hand
two broad categories of specificatoins
1) prescriptive
2) performance
prescriptive specs
- Product/materials/systems are specifically listed by name and # and there’s no substitutions allowed.
- aka Closed specifications
- specificy brand names
when should prescriptive specs be used?
You or the owner want to see something specific, because you want it, or know it will work best for the application (eg: Owner wants the same window to match the rest on the existing house)
who’s primarily responsible for prescriptive specifications?
contractor
performance specificiations
- tell what results the final construction assembly should achive
- give contractor some choice in how they will be achieved
- Like an open spec, but instead of listing manufactures, the required expectations/criteria and results for the intended system are given.
when should a performance spec be used?
-You don’t have a manufacture preference and the contractor can competitively bid
who is priamarily responsible for performance specifications?
Contractor
which spec is most restrictive
proporietary sepcs
- give architect complete control of what is installed
- do not allow for competitive bidding
- easier and shorter to write
- burden is on the specifier who must call out products that meet code requirements and within budget
base bid with alternates
- type of spec that calls out a propietary roduct but allows the substitution of other products that the contracto thinks are equal to the one stated
- dangerous method of specifying because contractor may substitute a less expensive item that he or shoe thinks is eual but is actually not
two variation of base bid specs
1) list several apporved manufacturers of a product
- contractor is free to bid on any one listed
- satisfies the requirement for public work where at least 3 manufacturers must be listed
- burden is on architect to make sure all options are equal
2) base bid with approved equal language
- states that one product or an approved equal must be used
- contractor may propose and substitution but it must be apporvied by architect
- burden on contractor for finding a substitution
- burden is also placed on architect to fairly and accurately evaluate proposed substituions from contracto
- spec must clearly state how much lead time the contractor must give the architect and how alternates will be evaluated
why are descriptive specs more difficult to write?
-architect must include all the pertitnent requirements for the construction and installation of the product
