General Estimating Flashcards
Who does the removal of loose furniture
Ideally, we would use Furniture Liquidators bc they are better for the environment and typically cheaper than Demo.
But the 2 options are either Demo or Furniture Liquidator
How do I know how many Electrical “stand by” days to include on a demo job?
Typical rule of thumb = 3,000 sq. Feet per day of stand by
What is a “Subtop” and who Furnish & Installs it?
A subtop is a supporting layer used under a freestanding table or peninsula counter top that uses a heavy top material (like marble, granite or aggregate material) to provide a base to attach your table legs or table base or bases to
Who Furnish / installs Top & Bottom Channel partitions.
F/I by Arch. Metal & glass.
Channel’s are the pieces that hold the glass (partition) in place.
What is the trade “Window Film” responsible for?
Window film contractors will furnish & install window film (sometimes referred to as “distraction banding”) at glass furnished/installed by others. By code, certain glassfront partitions (depending on size & location) require distraction banding to lower the risk
of injury from walking into it. Window film vendors will also provide / install window tinting.
Distractions bands = thin strips
Window film = full film from top to bottom of glass partition (more expensive)
Scaffolding
Scaffolding contractors provide working platforms for other tradespeople in order to reach places unreachable by other means. Scaffolding contractors also provide overhead protection to ensure the safety of persons below the area of work (i.e. a sidewalk bridge or working platform)
Typically not shown on the drawings. This is a means & methods trade. Consult a colleague or your estimating manager if unsure whether scaffolding is required.
Fine Cleaning
At the end of a project, some clients require a Final “White Glove” cleaning. Typical projects require a “Construction Clean” only which would be performed by JRM’s laborers and does not require a trade. If the drawings call for a “White Glove” cleaning, the 017423 - Fine Cleaning trade is required. If ambiguous on the drawings whether a construction clean or a Fine Clean is required, submit an RFI or discuss with your estimating manager.
Typically found as a note on the architectural drawings (A-XXX), also often found in the RFP or supporting documents.
Demolition
Demolition subcontractors perform all major & minor demolition. They will remove everything from the structural slab, to the finishes. Note that all MEP demolition requires the associated trade to prepare their work prior to demo (i.e. if removing electrical equipment, an electrician is required; if removing ductwork, an HVAC contractor is required; if removing plumbing fixtures, a plumber is required; if removing a sprinkler heads/piping, a Fire Protection contractor is required). Electricians safe-off electrical equipment so no-one is shocked, HVAC contractors cut duct/piping and place a cap on them so no air or water escapes and Plumbers / Fire Protection contractors cut & cap piping so water does not escape when demo commences. Note: Demo subcontractors will often give push-back for pricing surgical removals, including removal of wallcovering, stripping of paint, any salvage work, etc. Additional Note: JRM IS SIGNATORY TO LOCAL 79 meaning ALL PROJECTS require UNION Demo subcontractors, regardless of the labor requirement of the project.
Typically, if there is demo on a project, there will be demolition drawings (often tagged DM-001, 002, and so on).
Typical Keynote Tags: DM-X, D-X
Asbestos Removal
Asbestos Removal contractors do exactly that. They remove asbestos from “hot” areas in or around the work area prior to construction. Asbestos remediation is typically required on projects where asbestos containing materials are disturbed; often ceiling tiles, structural work, flooring & any space that was built prior to 1989 when asbestos was officially banned from new use in New York.
Typically shown in notes on the demo drawings (DM-XXX) or construction drawings (A-XXX) or their own asbestos abatement drawings.
Concrete Masonry Fireproofing
Concrete contractors typically handle the pouring of new concrete (stairs, new slab, sidewalk flags, etc.) or patching concrete. Masonry contractors are typically used for new or patching of existing masonry. Similarly, Fireproofing contractors are typically used for new or patching of existing fireproofing. Most contractors JRM contracts typically do all (3), Concrete, Masonry & Fireproofing. Note: JRM IS SIGNATORY TO LOCAL 79 meaning ALL PROJECTS require UNION concrete subcontractors, regardless of the labor requirement of the project.
Look for notes calling for patching of existing areas, or notes pertaining to new work (typically on Architectural drawings (A-XXX). Your structural drawings (S-XXX) will typically be a good place to look for new structural concrete pours. Often times, concrete/masonry/fireproof patching is not shown on the drawings but we include a team day allowance to cover anticipated patching.
Concrete Finishing
Concrete Finishing contractors are used to provide Polished Concrete finishes. They will typically either pour a topping slab or use the existing slab. With the slab, they then grind the slab down raising the “Grit” level until the desired finish is achieved.
Good place to look is the Finish Plan (A-XXX, often A-400).
PC-X; CON-X -> Note: CON-X also often times refers to new concrete pours, not to be mistaken with Polished Concrete.
Masonry
Masonry contractors are typically used for new or patching of existing masonry. Note: Masonry is NOT considered Local 79. If you have a heavy Non-Union Masonry project, ensure your masonry subcontractors are non-union, however Concrete Scope MUST be union (consult your estimating manager for exact concrete scope that is required by Local 79)
Look for notes calling for patching of existing areas, or notes pertaining to new work (typically on Architectural drawings (A-XXX). Look out for big penetrations in existing masonry walls (sometimes shown for MEP work on the MEP drawings (M-XXX, E-XXX, P-XXX, SP-XXX). Often times, masonry patching is not shown on the drawings but we include a team day allowance to cover anticipated patching.
Façade Restoration
Façade restoration contractors work on the façade or exterior face of the building. They will typically rework masonry, repoint stone or brick, modify limestone, patch or repair cracking etc.
Typically shown on the Architectural Drawings (A-XXX) and often times shown on elevations. If there is structural façade restoration work, it will typically be found on the structural drawings (S-XXX)
Structural Steel
Structural Steel contractors handle all heavy duty steel work, not to be confused with the “Architectural Metal & Glass Trade” which handles finished metal. Steel contractors will provide stair stringers, steel dunnage, metal decking, lintels & structural steel support @ rolling grilles (entry grilles -> think the gate in front of a store when closed) / operable (movable) partitions / oversized equipment / etc. Steel vendors will also frame openings in structural slabs & provide structural shoring (additional temporary support for areas of work to be supported with permanent steel later in the project).
Structural Steel scope will typically be found on the Structural Drawings (S-XXX). Note: If you have operable partitions, rolling grilles or oversized equipment, you will likely need structural steel to support it, even if not drawn. If that is the case, submit an RFI or consult a colleague / your estimating manager.
Convector Enclosures
Convector enclosures (sometimes referred to as Perimeter Induction Units) subcontractors will typically handle the physical enclosure covers that surround your perimeter induction units. The actual mechanical equipment (induction units) that runs through the convector enclosures will be handled by your HVAC contractor. Convector Enclosure contractors will often times powder-coat their NEW convectors in their shop. Note: Patching or painting of convectors enclosure in the field will typically be done by your painter depending on the severity of patchwork.
Typically the mechanical work for the induction units as well as the details for the convector enclosures will be shown on the Mechanical Drawings (M-XXX). Sometimes the convector enclosure details are found on the Architectural Drawings (A-XXX) towards the back of the set.
Decorative Stairs
Decorative Stairs Contractors will handle your entire stair scope. They will provide the stringers, handrails, guardrails, treads, nosings, risers, etc. They will NOT typically provide the demo for the slab opening or the concrete patching.
Typically a combination between the Architectural Drawings (A-XXX) & the Structural Drawings (S-XXX).
Waterproofing
Waterproofing contractors provide waterproofing for wet areas. You will often see bathrooms, storefronts, mechanical/electrical rooms & pantries require waterproofing. Note: Bathrooms & Pantries often schedule stone floor or wall tile: the waterproofing below the finished floor will be picked up by your Ceramic Tile & Stone vendors.
Often found on architectural details, otherwise in keynotes on Architectural Plans (A-XXX).
Roofing
Roofing contractors handle all penetrations, pitch pockets, roof pavers, flashing, waterproofing, etc. Roofing Contractors provide all scope @ your roof, new or existing.
Often found on architectural details, otherwise shown on Architectural Plans (A-XXX), typically in keynotes.
Fireproofing
Fireproofing contractors are typically used for new or patching of existing firestopping. Typically, fireproofing will be “Spray-On Fireproofing” or “SOFP” which is applied by being sprayed to the desired location. Most contractors JRM hires typically do all (3), Concrete, Masonry & Fireproofing. Note: JRM is signatory to Local 79 which means all CONCRETE work must be UNION, regardless of project labor requirement.
Look for notes calling for patching of existing areas, or notes pertaining to new work (typically on Architectural drawings (A-XXX). Often times, fireproof patching is not shown on the drawings but we include a team day allowance to cover anticipated patching.
Firestopping
Firestopping contractors will provide firestopping at penetrations through fire-rated assemblies (slab, fire rated walls, etc.). When a pipe, duct, conduit, etc. goes through a wall that is fire rated, the firestopping contractor will fire-caulk around the penetration to seal the assembly and maintain the rating. Typically, we like to have each responsible trade include all firestopping of their own penetrations (i.e. the HVAC subcontractor will firestop around their own duct penetration, a plumber will firestop around their own piping penetration, a sprinkler contractor will firestop around their own piping penetration and electricians will firestop around their conduit / cable penetration.
Typically shown as a keynote on the architectural drawing. All fire rated assemblies are required to be firestopped regardless of whether or not it is specifically called out on the drawings. It is good practice to put make the following line on your leveling sheet -> “This contractor to firestop all penetrations through fire-rated assemblies created by this contractor.”
Doors Frames Hardware
Doors Frames & Hardware vendors will FURNISH & DELIVER ONLY hollow metal (HM) doors, hollow metal (HM) frames & the hardware for all hollow metal AND wood doors. These contractors will NOT typically provide wood doors, wood frames, glass doors, or hardware for glass doors. Your drywall subcontractor will provide the install for the hollow metal doors & frames, and your Architectural Woodworkers will provide the furnish and install of your wood doors & frames. Your Doors Frames & Hardware vendor will also provide the keying for the locks of all of your doors. If master keying is required, ensure your Doors vendor includes the master keying by the building locksmith.
Typically shown on the “Door Schedule” or “Door & Hardware Schedule,” often times towards the back of your Architectural Set (A-XXX). The location of your doors is typically found on your “Construction Plan” with a door tag, often a # with a circle around it.
Rolling Grilles & Shutters
Rolling Grilles & Shutters vendors will provide & install your rolling grilles & fire shutters. Rolling Grilles are typically found on ground-level projects with access to the street (Think a store after hours with the metal gate that secures the stores entrance). Fire shutters are rolling shutters that when triggered (typically by the fire alarm system), will roll down and prevent the fire from spreading to other locations within the building.
Typically shown on the architectural drawings (A-XXX), specifically the ceiling details. Sometimes, grilles & shutters are shown on the structural drawings for new slab openings / stairs
Storefronts, Entrances & Curtain Walls
Storefront vendors will provide all Metal & Glass Finishes @ the storefront, often times, inclusive of low-gauge steel. They will provide and install the following: Glass Panes, Glass Doors, Revolving Doors, Frames & Hardware for Glass Doors, Metal Accents, Canopies, Transoms, etc.
Typically shown on Architectural drawings, details & elevations (A-XXX) and sometimes on Structural Drawings (S-XXX)
Officefronts
Officefronts vendors will furnish & install all officefront glass partitions, officefront glass doors, officefronts frames and officefronts hardware. Note: if not specific manufacturer or vendor is specified, your architectural metal & glass subs should be able to price this scope. Additional note: Check the partition schedule. More often than not, the glassfront/officefronts will have a drywall/stud header or low wall. Each partition may require the drywall contractor as well.
Partitions typically shown on Construction Plan (A-XXX, often A-100), Doors & Hardware typically shown on “Door & Hardware Schedule.” All typically shown in elevation & details
Windows
Window vendors will furnish & install new exterior-facing windows.
Typically shown on the architectural drawings as keynotes & in details / elevations (A-XXX)
