Preliminary estimating answers the first cost question: does the concept fit the pro forma before design dollars are spent? Sky Estimates Nashville builds ROM figures from sketch plans, massing studies, and program narratives when the drawing set is still thin.
Every total rests on high, documented assumptions tied to footprint area, building type benchmarks, and key drivers such as structure type, parking ratio, and envelope complexity.
Whether you are testing a mixed-use concept or underwriting a site acquisition, early ROM modeling supports investor conversations and a clear go or no-go call on schematic design spend.
Preliminary estimating operates with the least design information in the project lifecycle. Sky Estimates Nashville applies parametric unit rates and assembly assumptions when wall sections, MEP layouts, and finish schedules do not yet exist.
Each package includes a written assumption log that flags where totals depend on pending decisions, so developers and lenders understand the confidence band around every ROM figure.
Deliverables focus on feasibility summaries, sensitivity on key drivers, and broad division outlines. They are not bid-level quantity sheets that require construction documents.
Gross and net building square footage from sketch plans
Cost per SF sensitivity across low, base, and high scenarios
Structure type assumptions: wood frame, steel, or concrete

Tests go or no-go feasibility before design spend
Anchors investor and lender conversations early
Surfaces cost risk on key drivers while design is open
Sets realistic pro forma targets for acquisition teams
Documents high assumptions for stakeholder alignment
Informs whether to proceed to schematic design
We start from the fewest sheets available and identify missing concept information before figures reach decision makers.
Sensitivity tables show which drivers move ROM totals most, such as area, structure type, and parking, so developers know which assumptions deserve design attention first.
As sketches advance toward schematic design, we support updated preliminary passes and transition into allowance-based schematic and DD budget estimating when drawing depth allows.

Every assumption is logged and tied to the ROM figure it supports. Where information is missing, we state the default used and flag it as a sensitivity item so stakeholders know what could move the total.
Yes. Typical sensitivity covers building area, structure type, parking count, and envelope complexity so developers can see how changes to major assumptions affect the ROM range.
Once schematic design drawings are issued with resolved area schedules and basic systems direction, budget estimating replaces concept ROM work with allowance-based schematic and DD budgets.
