Structural Steel Estimating Services in New York

Create a member schedule that can be checked

Read framing plans with sections, elevations and member schedules. Record each member’s mark or location, section designation, quantity and length basis. Beams, girders and columns should reconcile across levels without counting a member again because it appears in both plan and elevation.

Keep channels, angles and HSS distinguishable from other sections. Use a documented section-weight source and retain its units. A member schedule should show how quantities become a weight total, including whether lengths are nominal design lengths or another agreed estimating basis.

For high-rise construction, review transfer levels, roof framing and non-typical floors separately. Repetition is a useful check, but it should not erase changes in size or detail between levels. A quantity takeoff can retain this location-based organization without adding pricing.

Separate the frame from its associated components

Joist and deck quotations need their own inclusion review. A supplier may cover the main products but exclude related edge material, closures or installation. Identify the actual package instead of converting every component into one undifferentiated tonnage figure.

Check the structural steel, metal decking, fabrication and coating specification sections supplied for the project. Their titles and requirements establish the scope; do not assume every project uses identical section numbering or package assignments.

Keep incomplete connection information visible

Count connection materials where drawings or supplied details provide a basis. When connections remain undefined, state the estimating allowance and what it covers rather than inventing plate sizes, bolt counts or weld details. The responsible design and fabrication parties resolve those requirements.

Base plates and bearing plates need coordination with concrete and masonry. Identify who furnishes anchors or embeds, who sets them and who carries related grout or repairs. The same supply cost should not sit unnoticed in both packages.

AISC’s fabrication guidance provides technical references for steel fabrication questions. The estimating deliverable follows the issued project information and does not include structural engineering, connection design or shop drawings unless separately verified and commissioned.

Price fabrication and erection on an explicit basis

Material weight does not describe all fabrication effort. Member variety, plates, holes, welding and assembly requirements can change the work behind a similar tonnage. Use supplier and fabricator quotations or agreed estimating inputs, keeping the original quote qualifications accessible.

For erection, request the proposed sequence, access and lifting assumptions from the contractor. In Manhattan, delivery and staging information can matter to that basis. Queens projects also need their actual access conditions described instead of inheriting assumptions from another site.

Identify temporary bracing, erection support and equipment responsibilities where the contract defines them. Cost allowance for an instructed item is different from designing a safe erection method. Keep the planning and engineering responsibility with the appointed professionals.

Coordinate coatings, fireproofing and miscellaneous work

Record which members require the documented primer, galvanizing or other finish and who provides it. Field touch-up, preparation and inaccessible areas may need separate scope notes. Do not assume all frame steel receives the same treatment.

Fireproofing scope should follow the specified system and locations, with responsibility for preparation and interface conditions identified. Stairs, railings and other miscellaneous steel belong in metals estimating when assigned to that package; coordinate any support steel without duplicating it.

For industrial buildings, verify equipment support and vendor boundaries. Commercial projects may also have architecturally exposed or separately finished items that require a distinct quotation basis.

Define the steel review package

Submit framing plans, member schedules, connection details, specifications and issued revisions. Include joist, deck or fabrication quotes available for use, plus the requested supply/erect split. Identify existing steel alterations and unresolved design information at the outset.

Deliverables can include a member and weight schedule, deck areas, documented connection quantities and a list of exclusions or allowances. Cost estimating adds agreed pricing, while subcontractor estimating supports the proposal scope. Review file formats and send the steel package with the required review date.
