TERM 3 Sequence of Specifications DEFINITION 3 (1) Invitation to bid (RFP, i.e.: Request for Proposal)(2) Instructions to bidders(3) Bid forms(4) Form of owner/contractor agreement(5) form of bid bond(6) Forms of performance bond(7) Alternates(8) General conditions of the contract(9) Supplementary general conditions(10) Technical trade sections TERM 4 Master format DEFINITION 4 This is a standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. Construction Specifications Institute (CSI) TERM 5 MasterFormat Numbering System DEFINITION 5 01-50-00-00 TERM 6 Procurement and Contracting (includes) DEFINITION 6 Advertisement for bidsInvitations to bidInstructions to biddersPre-bid meetingsLand survey informationGeotechnical informationBid formsOwner- contract agreement formsbond formsCertificate of substantial completion and certificate of completionConditions of the contract. TERM 7 Invitation to bid DEFINITION 7 Public construction projects are posted in public entities such as newspapers, trade journals, and magazines.This includes the request for bid proposal, receipt of bids, prime contract, and location of plans and specs. TERM 8 Advertisement to Bid DEFINITION 8 Sets the method of the bidding process such as location, extent and nature of work to be performed.This includes the bid security (bid bond), performance bond, and proposal indo. TERM 9 Instruction to bidders DEFINITION 9 This document states the procedures to be followed by all bidders.The manner/date/time of delivery, location of bid opening, and public vs private nature of the project. TERM 10 Proposal forms DEFINITION 10 Verify where the bids are to be received, any necessary addendum, and the time/local for changes.Local/time, base bid, alternates, date of completion, addendum acknowledged, and responsibility of bidder. TERM 21 RS Means DEFINITION 21 Reported by contractors, designers, and owners it is a national project based cost analysis of a site in the current year and averaged TERM 22 Conceptual Estimate DEFINITION 22 Based on the project type and quality value, this form of estimate can be made by multiplying the cost times the number of units.(Number of units) x (unit cost) = total costThis # will reflect the typical cost of building of the designated properties. TERM 23 Estimate DEFINITION 23 is an educated guess, appraisal, opinion, or approximation of the cost of a project prior to its actual construction.It provides, owner, designer, and contractor perspectives. TERM 24 Types of Estimating DEFINITION 24 An estimate can be preformed at any point during the project dependent on its purpose.Types include:(1) Conceptual(2) Schematic(3) Design Development(4) Procurement TERM 25 Estimating's Big Three DEFINITION 25 CustomizationBudgetSquare footage (often schedule in our management terms)**Typically an owner cannot have all three TERM 26 Conceptual Phase DEFINITION 26 A project description (a sketch or brief description) that provides an idea of unknown size though it make highlight the capacity. TERM 27 Conceptual or ROM estimates DEFINITION 27 This type of estimate prepared with very little information, relying more on historic data and whatever descriptions are available.this is the broadest based estimate requiring more time and is the least accurate (20%) TERM 28 Unit Cost per SF/CF DEFINITION 28 Cost calculated per SF or CFArea take offs of project must be calculated for the major building elements and therefore takes more time (>ROM time) but increases accuracy (15%) TERM 29 Assemblies Estimates DEFINITION 29 "Systems estimate"Prepared by working the systems via detailed units (Ie: # of plumbing fixtures) this estimate is performed late in the design state.Accuracy within 10% TERM 30 Procurement Phase DEFINITION 30 known as the "buying out" of the job, purchasing labour, materials, equipment, etc needed for project completion.Contractor's Detailed Estimate -> Bid awarded -> project start -> project completion -> post completion TERM 31 Detailed Estimate DEFINITION 31 Prepared using contract docs for entire project covering a single phase or for entire "work package" of project.this requires material qualities, construction methods, and project conditions understanding5% accurate TERM 32 Owner's Team Detailed Estimate DEFINITION 32 "fair cost estimate"A detailed estimate is prepared, to be used for negotiation of a fair price and to verify accuracy of contractors, by this party. TERM 33 Contractor Detailed Estimate DEFINITION 33 the contractor prepares a DE to identify which price to bid TERM 34 DEFINITION 34 Accuracy of Estimate Visual TERM 35 Estimate Considerations (4) DEFINITION 35 (1) Project size(2) Project quality(3) Project location(4) time period in which project is to be constructed TERM 46 Daily Output DEFINITION 46 activity duration (in workdays) = (total quanity) (Daily output) TERM 47 Labour Hour DEFINITION 47 activity duration (in workdays) =(total quanity) x(prod. rate/item) TERM 48 Productivity DEFINITION 48 increase as unis repeat but reach a maxdecrease the farther the crew/men must travel to work one.Is affected by weather: extreme temps, bad weather, protection procedures, out-of-season constrctn, cost and availability of resources. TERM 49 Logical Sequence DEFINITION 49 takes into account the relationship btwn the diff. act. req to construct said facility, i.e.: production, procurement, and admin. act.Constraints: physical relationship among prjct components. resource relationships safety and cod regs referential relationships (how scheduler prefers schedule to work) TERM 50 Physical Relationships of Seq Prod DEFINITION 50 among the project components to be supported and covered by, and embedded in. TERM 51 Resource relationship DEFINITION 51 Space competition, resource limitations, and requirement of service TERM 52 Safety and Code Regs DEFINITION 52 Tying off and tagging out (E work) TERM 53 Preferential Relationships DEFINITION 53 Ie: curb and gutter goes in before rough grading of the site TERM 54 Sequencing Procurement Activities DEFINITION 54 Follows a basic sequence of events that is typically standard for a project TERM 55 Masonry Walls DEFINITION 55 Two types of masonry walls: bearing and non-load bearing walls TERM 56 Non-load Bearing walls DEFINITION 56 These include shear, retaining, partitions, infill and cladding TERM 57 Masonry shear wall infill DEFINITION 57 Allows live load beam deflect and supports columns for lateral loads(pic with top/one sided infill) TERM 58 Masonry non-shear wall infill DEFINITION 58 (pic with three sided fill)Allows both column and beam deflectionSupports neither columns nor beams for loads TERM 59 Bearing Wall DEFINITION 59 A wall that supports gravity loads in addition to its own self load TERM 60 Middle Third Rule DEFINITION 60 States that no tension is developed in a wall or foundation if the resultant force lies within the middle third of the structure.Creates an uniform compression if the load is centred on the rigid block
