True Data · Data format

The shape of a contributed project

This is the format project data is normalized to for use in benchmarks. Each record type below lists its fields and the vocabularies give the allowed values for the categorical fields. Some information may not be available on every project; fields marked req are generally required for a project to be qualified for market-data comparisons.

Cost is normalized to the UniFormat Level 2 elemental level and not available more finely on market-data benchmarks, but own-data and peer-network data (at admin and member discretion) may include more detailed and/or additional cost coding. See the methodology for more information about conditioning and privacy.

Record types

Project

Type

A single construction project contributed to the corpus. A project carries its descriptive attributes (type, location, delivery, sustainability and quality targets) plus a history of design checkpoints — point-in-time snapshots that hold the project's size, program, design metrics, and cost estimate as the design progressed. Schedule milestones and a risk register round out the record. Provide whatever you have; only a name and type are needed to start.

Field	Type	Description
idreq	string	GUID — unique identifier for this project.
namereq	string	The project's name.
typereq	ProjectType	The primary use of the project. Choose the single closest category.
statusreq	ProjectStatus	The current outcome / lifecycle status of the project.
sector	Sector	Whether the project is privately or publicly owned and funded.
wageBasis	WageBasis	The labor wage basis for the construction work — union or open shop.
deliveryMethod	DeliveryMethod	How the project is contracted and delivered (e.g. design-bid-build, design-build, CM at risk).
city	string	The city the project is located in.
region	string	The state or province the project is located in.
country	string	The country the project is located in. The USA if omitted.
macroRegion	Region	The broad geographic region the project falls in. If omitted, it is inferred from the state.
checkpointsreq	Checkpoint[]	The project's design checkpoints — one per estimate milestone (concept, schematic design, design development, and so on). Each checkpoint captures the project's size, program, metrics, and cost estimate as of that point in design. Contribute as many as you have; a single late-stage checkpoint is fine.
createdAtreq	IsoDate	When this project record was first added to the corpus. Set by the pipeline, not the contributor.
updatedAtreq	IsoDate	When this project record was last updated. Set by the pipeline, not the contributor.

Checkpoint

Type

A snapshot of the project at one point in design — usually tied to an estimate milestone such as schematic design (SD) or design development (DD). A project has one checkpoint per milestone (the phase identifies it), each holding the project's size, program breakdown, design metrics, and cost estimate as they stood at that time.

Field	Type	Description
statusreq	DataStatus	The data status of the checkpoint in the corpus — whether its data is ready to benchmark against, still in review, or excluded (for data-quality reasons or because the contributor opted out).
phasereq	DesignPhase	The design phase this snapshot represents. A project has one checkpoint per phase — the phase is what identifies it.
datereq	IsoDate	The as-of date this estimate/snapshot was produced. Used to escalate costs and filter for relevance.
currencyreq	Currency	The currency every cost line in this checkpoint's estimate is expressed in.
programRequirementsreq	ProgramRequirements	Description of special requirements on this project. Benchmarks correlate these with cost/schedule/risk.
componentsreq	Component[]	The project broken into its component areas at this checkpoint (e.g. residential tower, parking, retail podium), each classified by use type, program class, and space function.
costLinesreq	CostLine[]	The cost estimate at this checkpoint, as elemental line items coded to UniFormat Level 2.
expectedContingencyPctreq	number	The cost contingency carried for the project, as a percentage of construction cost (e.g. 7.5).
metricValuesreq	MetricValue[]	Project-wide design and program metrics at this checkpoint (e.g. exterior wall area, window area, annual energy use). Every checkpoint must lead with GROSS_FLOOR_AREA, SITE_AREA, STORY_COUNT, BELOW_GRADE_STORY_COUNT, in that order; all other metrics are optional and may follow in any order.
schedulereq	ScheduleMilestone[]	Major schedule milestones for the project. Benchmarks compare the durations between them.
riskRegisterreq	RiskEntry[]	The risks tracked for the project, each scored by likelihood and impact.

ProgramRequirements

Type

A description of targets and special program requirements for this project. Benchmarks correlate these with cost, schedule, and risk. All the requirement drivers are optional — provide the ones you know; the special systems and FF&E are lists of what the project includes.

Field	Type	Description
specialSiteRequirements	SpecialSiteRequirements	Degree of site difficulty — subsurface conditions and grade variation.
sustainabilityTarget	SustainabilityTarget	The project's energy or sustainability certification target, if it has one.

ffereq	FfeItem[]	The furnishings, fixtures & equipment the contribution includes — any of the FfeItem values.

Component

Type

A portion of the project grouped by how it is used — for example a residential tower, a parking structure, or a hospital's surgical platform. Attributing costs and metrics to a component lets benchmarks compare like-for-like areas across projects. Three required fields classify a component: useType names the owner program area it serves, programClass names where it sits in the building's anatomy, and functionType names the specific space function below useType. A hospital surgery component, for instance, is useType: HEALTHCARE_INPATIENT, programClass: FUNCTIONAL_SPACES, functionType: OPERATING_ROOMS; the garage beneath it is useType: PARKING, programClass: FUNCTIONAL_SPACES, functionType: BELOW_GRADE_PARKING. Building-fabric components — sitework, core, and shell — have no single space function, so their functionType echoes their program class (SITEWORK, CORE, SHELL), with CORE_SHELL for the combined core+shell grossing many fit-out takeoffs report as one floor-area figure. Split a genuinely mixed area into separate components so each is dominated by a single function.

Field	Type	Description
idreq	string	A unique reference for this component — what cost lines attribute to (CostLine.componentId).
namereq	string	A short label for this component, e.g. "Residential Tower", "Below-grade Parking", or "Surgical Platform".
useTypereq	UseType	The owner program area this component serves. Drives which program metrics apply — each UseType value's description names the key Metric values to provide.
programClassreq	ProgramClass	Where this component sits in the building's anatomy — sitework, core, shell, or one of the space classes.
constructionType	ConstructionType	Whether this component is new construction, a renovation, or a tenant improvement. Per-component, so a single project can mix scopes (e.g. a new wing alongside a renovated department).
functionTypereq	FunctionType	The specific function of the space, refining useType — e.g. OPERATING_ROOMS within HEALTHCARE_INPATIENT. Building-fabric components (with no single dominating function) name their fabric element — SITEWORK, CORE, or SHELL — echoing their program class. Should be consistent with useType; this is checked during normalization. Selecting a functionType requires the metrics that function scales by — each FunctionType value lists its required set (a building-fabric function requires the one metric it scales by).
metricValuesreq	MetricValue[]	Program and design metrics for this component — the key program counts for its use type (e.g. UNIT_COUNT for RESIDENTIAL, BED_COUNT for HEALTHCARE_INPATIENT) plus shared measures like GROSS_FLOOR_AREA. The leading rows must be the functionType's required metrics, in the order listed on that value; any additional measures may follow.

MetricValue

Type

A single measured value for a metric. Every value belongs to either a checkpoint (a project-wide metric, in Checkpoint.metricValues) or a component (a metric for one program area, in that Component's metricValues) — which list it sits in is what attributes it. Provide values in whatever unit you measured; they are normalized to the metric's canonical unit before benchmarking.

Field	Type	Description
metricreq	Metric	Which metric this value measures.
valuereq	number	The measured number, in `unit` — or in the metric's canonical unit if `unit` is omitted.
unit	Unit	The unit the value is expressed in. Must match the metric's dimension (e.g. an area unit for GROSS_FLOOR_AREA); if omitted, the metric's canonical unit is assumed.

CostLine

Type

One elemental line of a cost estimate. Every line is classified by an extensible list of cost codes: the two UniFormat levels are required and lead, and a contributor may attach further codes — its own internal cost codes, or another standard such as MasterFormat — so a line reconciles to both the shared taxonomy and its native coding. Where possible a line is attributed to a design component (componentId) so cost ties back to a specific part of the project. Benchmarks are only ever published at UniFormat Level 2 or coarser — never as finer-grained unit prices.

Field	Type	Description
codesreq	CostCode[]	How this line is classified. The two UniFormat levels are required and must lead — a UNIFORMAT_L1 major group (e.g. "B") then its UNIFORMAT_L2 element (e.g. "B20", Exterior Enclosure) — after which any number of additional codes may follow: your own internal cost codes, or another standard such as MasterFormat. Benchmarks are computed on the shared UniFormat taxonomy and never published finer than Level 2; the additional codes are kept for your own reconciliation.
description	string	A short description of what the line covers; the standard UniFormat element name is assumed if omitted.
costreq	number	The line's cost in the checkpoint's currency, as estimated — before any time, location, or currency normalization.
componentId	string	The id of the Component this cost is attributed to, if known — omitted for project-wide lines (site & shell).

CostCode

Type

One classification of a cost line under a single coding system. The benchmarking backbone is the pair of UniFormat codes every line is required to carry (shared across the whole corpus, so costs compare like-for-like); a member company may attach further codes — its own internal cost codes, or another standard such as MasterFormat — letting the same estimate reconcile to both the shared taxonomy and the contributor's native coding without either giving way. Recognized standards are named by system; a member's own system uses CUSTOM and names itself in systemLabel.

Field	Type	Description
systemreq	CostCodeSystem	The coding system this code belongs to — a recognized standard (UNIFORMAT_L1, UNIFORMAT_L2, MASTERFORMAT) or CUSTOM for a system you define.
systemLabel	string	For a member-defined system (system: CUSTOM), the name of that system as you call it, e.g. "Acme WBS" or "GL account". Ignored for the standard systems, whose name is fixed.
codereq	string	The code within the system — "B" or "B20" for the UniFormat levels, "26 05 00" for MasterFormat, or whatever value your own system uses.
label	string	What the code denotes, when it isn't derivable from a standard catalog (the UniFormat element name is assumed for UniFormat codes if omitted).

ScheduleMilestone

Type

A dated milestone in the project schedule. The durations between milestones are what schedule benchmarks compare.

Field	Type	Description
namereq	string	The milestone's name, e.g. "Notice to Proceed" or "Substantial Completion".
datereq	IsoDate	The date the milestone is planned for or was reached.

RiskEntry

Type

An entry in the project's risk register, scored by likelihood and impact.

Field	Type	Description
namereq	string	A short name for the risk.
descriptionreq	string	A fuller description of the risk.
likelihoodreq	number	How likely the risk is to occur, on a 1–5 scale.
costImpactreq	number	How severe the cost impact would be if it occurs, on a 0–5 scale.
scheduleImpactreq	number	How severe the schedule impact would be if it occurs, on a 0–5 scale.
statusreq	RiskStatus	Whether the risk is still open or has been closed out.
mitigation	string	The plan to mitigate or manage the risk, if one has been set.

Vocabularies & value types

UseType

Enum

The owner program area a component serves — what the space is for, in the owner's terms. Classifies the major program areas that carry different owner-driven program metrics; each value's description names the key Metric values to provide for components of that use. Choose the single closest category, and split a genuinely mixed area into separate components rather than forcing one value. Orthogonal to ProgramClass (where the component sits in the building's anatomy) and refined by FunctionType (the specific space function).

OTHER: A use not covered above. Prefer a specific value where one fits. Key program metric: GROSS_FLOOR_AREA.

ProgramClass

Enum

The spatial class of a component — which part of the building's anatomy it represents, independent of the owner program it serves (that is UseType's job). Splitting an area by program class lets benchmarks separate what the program itself costs from what the site, structure, core, and services wrapped around it cost.

SITEWORK: Work outside the building enclosure — earthwork, site utilities, paving, landscape, and other site improvements.
CORE: The vertical core — elevators, stairs, shafts, and the service rooms banked with them.
SHELL: The primary structure and enclosure — foundations, superstructure, exterior walls and glazing, and roof — independent of interior fit-out.
FUNCTIONAL_SPACES: The spaces that directly deliver the owner's program — dwelling units, patient rooms, operating rooms, classrooms, data halls, sales floors.
SERVICES_SPACES: Spaces that house building systems — mechanical and electrical rooms, plant, and telecom rooms.
CIRCULATION_SPACES: Horizontal circulation and gathering — corridors, lobbies, waiting, and other space that moves people between functional spaces.
INDIRECT_SERVICES: Support spaces that serve the building indirectly rather than any one program area — loading, waste handling, janitorial, general storage, and staff support.

FunctionType

Enum

The specific function of the space a component holds — a finer taxonomy than UseType, distinguishing for example the operating rooms from the patient units within one hospital. Benchmarks use it to scale comparable projects to fit a target program. Choosing a component's functionType fixes the metrics it must measure — the required-metrics column lists that set, in order (the leading rows of the component's metricValues), with the function's primary scaling metric in bold; further measures may always follow. Every component names one; split components rather than blending functions. Building-fabric components (sitework, core, shell) have no single space function, so they take the like-named SITEWORK / CORE / SHELL values, each requiring the one metric it scales by (site area, elevator cabs, envelope area) — plus CORE_SHELL for the combined core+shell grossing, which scales by gross floor area. A component's functionType should be consistent with its useType (OPERATING_ROOMS with HEALTHCARE_INPATIENT, DATA_HALL with DATA_CENTER) — inconsistent pairs are flagged for review during normalization, though some pairings are legitimately cross-sector (e.g. FOOD_BEVERAGE in an office building).

Metric

Enum

The measured metrics — the underlying countable values a contribution provides directly, as MetricValue rows. Every project and component type has a natural set of metrics of interest, and many are shared across types (e.g. GROSS_FLOOR_AREA); each UseType value's description names the key metrics for components of that use. Values are named without units — the canonical-unit column shows the unit each value is normalized to, and the description states how to measure it and whether it applies checkpoint-wide or per component. A contribution may supply any dimensionally compatible unit via MetricValue.unit.

Value	Canonical unit	Description
GROSS_FLOOR_AREA	SF	Total constructed floor area, in square feet, measured to the exterior face of the enclosing walls and including every enclosed level. The universal denominator of the derived efficiency metrics (SKIN_TO_FLOOR_RATIO, NET_TO_GROSS_RATIO, FLOOR_AREA_RATIO, the area-per-count intensities). Expected on every checkpoint, and per component for like-for-like comparison.

A direct driver of envelope, structure, and MEP riser cost, benchmarked against type norms (roughly 9–10 ft residential, 13–15 ft office and lab, 14–16 ft healthcare). Provide per component in mixed-use projects.
CLEAR_HEIGHT	ft	Clear height from finished floor to the lowest overhead obstruction, in feet, at the typical bay. A key capacity driver for warehouses (racking), data halls (airflow), and GMP suites (interstitial space).

DerivedMetric

Enum

The standardized efficiency ratios computed from the measured metrics — the formula column shows each one's defining computation. Contribute the measured inputs rather than these: the derived values are computed consistently across the corpus by the benchmarking pipeline, and a benchmark simply doesn't appear when its inputs weren't contributed.

Value	Formula	Description
FLOOR_AREA_RATIO	GROSS_FLOOR_AREA ÷ SITE_AREA	The standard zoning and density measure of how intensely the site is developed (dense urban mixed-use commonly runs 8–12). Checkpoint-wide.
SKIN_TO_FLOOR_RATIO	GROSS_EXTERIOR_WALL_AREA ÷ GROSS_FLOOR_AREA	The classic envelope-efficiency measure: lower values mean a more compact massing enclosing the same floor area (0.32–0.45 is typical of a concrete mid-rise). Applies to any enclosed building.
WINDOW_TO_WALL_RATIO	WINDOW_AREA ÷ GROSS_EXTERIOR_WALL_AREA	The fraction of the envelope that is glazed. Balances facade cost, daylight, and thermal performance (0.30–0.45 is a common target band). Applies to any enclosed building; not meaningful for largely windowless types such as data halls and warehouses.
NET_TO_GROSS_RATIO	NET_FLOOR_AREA ÷ GROSS_FLOOR_AREA	The broadest plan-efficiency measure: how much of the constructed area serves the program directly. Applies to every use type, checkpoint-wide or per component.
RENTABLE_EFFICIENCY	RENTABLE_FLOOR_AREA ÷ GROSS_FLOOR_AREA	The headline pro-forma efficiency for income-producing buildings — how much of what is built can be leased or sold. Applies to multifamily, office, retail, and mixed-use components.
CIRCULATION_FACTOR	CIRCULATION_AREA ÷ GROSS_FLOOR_AREA	Flags plans that spend an outsized share of area moving people rather than serving program — a key lever in multifamily corridor planning and healthcare departmental layouts. Applies to every use type.
MECHANICAL_FRACTION	MECHANICAL_AREA ÷ GROSS_FLOOR_AREA	Separates process-driven buildings from conventional ones: expect it high on pharmaceutical (often 30–50%), healthcare, and data center projects and low on residential. Applies to every use type.
SITE_COVERAGE	BUILDING_FOOTPRINT_AREA ÷ SITE_AREA	The share of the site the building occupies at grade — a massing and zoning measure that pairs with FLOOR_AREA_RATIO. Checkpoint-wide.
AREA_PER_UNIT	GROSS_FLOOR_AREA ÷ UNIT_COUNT	Square feet per dwelling unit. Captures unit sizing plus the plan efficiency wrapped around it; read alongside RENTABLE_EFFICIENCY to separate the two. Residential and multifamily components.
AREA_PER_BED	GROSS_FLOOR_AREA ÷ BED_COUNT	Square feet per bed (BGSF per bed). The canonical hospital sizing benchmark. Applies to healthcare and senior living.
AREA_PER_KEY	GROSS_FLOOR_AREA ÷ KEY_COUNT	Square feet per key. The standard hospitality sizing benchmark, sensitive to amenity and back-of-house program. Hospitality components.
AREA_PER_WORKSTATION	NET_FLOOR_AREA ÷ WORKSTATION_COUNT	Square feet per seat. The workplace density benchmark. Office components.
AREA_PER_CLASSROOM	GROSS_FLOOR_AREA ÷ CLASSROOM_COUNT	Square feet per classroom. A program-efficiency benchmark for education projects.
AREA_PER_SEAT	GROSS_FLOOR_AREA ÷ SEAT_COUNT	Square feet per seat. The sizing benchmark for assembly, civic, and performance venues.
AREA_PER_PARKING_SPACE	GROSS_FLOOR_AREA ÷ PARKING_SPACE_COUNT (parking component)	Square feet per stall, within the parking component. The structured-parking efficiency measure (typically 300–400 square feet per stall). Parking components.
PARKING_RATIO	PARKING_SPACE_COUNT ÷ UNIT_COUNT	Stalls per dwelling unit. The residential parking-provision benchmark; per-bed and per-key analogues derive the same way. Multifamily and mixed-use.
AMENITY_AREA_PER_UNIT	AMENITY_AREA ÷ UNIT_COUNT	Square feet per dwelling unit. A market-positioning benchmark for multifamily and senior living.
GROSSING_FACTOR	GROSS_FLOOR_AREA ÷ DEPARTMENT_GROSS_AREA	The building grossing factor: how much whole-building area each square foot of clinical department requires once inter-department circulation and support are added. A core healthcare planning-efficiency benchmark. Healthcare projects only.
AREA_PER_OPERATING_ROOM	DEPARTMENT_GROSS_AREA ÷ OPERATING_ROOM_COUNT (surgical component)	Square feet per OR, within the surgical component. Sizes the surgical platform. Healthcare projects only.
AREA_PER_EXAM_ROOM	DEPARTMENT_GROSS_AREA ÷ EXAM_ROOM_COUNT (clinical component)	Square feet per exam room, within the clinical component. The clinic-module efficiency benchmark for outpatient work. Healthcare projects only.
POWER_DENSITY	IT_LOAD_CAPACITY (W) ÷ DATA_HALL_AREA	Watts per square foot of data hall. The headline density measure of a data center design; rising rack densities (liquid cooling, AI loads) push it up sharply. Data center projects only.
POWER_PER_RACK	IT_LOAD_CAPACITY ÷ RACK_COUNT	Kilowatts per rack. Distinguishes conventional enterprise halls (roughly 5–10 kW per rack) from high-density and AI halls (30 kW and beyond). Data center projects only.
COOLING_TO_IT_RATIO	COOLING_CAPACITY (× 3.52 kW/ton) ÷ IT_LOAD_CAPACITY	Expresses cooling redundancy and efficiency against the critical load. Data center projects only.
DATA_HALL_FRACTION	DATA_HALL_AREA ÷ GROSS_FLOOR_AREA	The white-to-gross share: how much of the building is revenue-generating IT space versus electrical, mechanical, and support gray space. Data center projects only.
CLEANROOM_FRACTION	CLEANROOM_AREA ÷ GROSS_FLOOR_AREA	The classified share of the building — the single strongest cost driver on pharmaceutical and GMP work. Pharmaceutical, GMP, and semiconductor projects.
VENTILATION_INTENSITY	AIR_HANDLING_CAPACITY ÷ GROSS_FLOOR_AREA	CFM per square foot. Captures how air-change-driven the building is; cleanroom and healthcare programs run far above commercial norms. Pharmaceutical, healthcare, and lab projects.
EMBODIED_CARBON_UPFRONT_INTENSITY	EMBODIED_CARBON_UPFRONT ÷ GROSS_FLOOR_AREA (m²)	kgCO₂e per m² — the unit embodied-carbon targets are quoted in (the floor area converts to square metres). The standard up-front carbon benchmark. Checkpoint-wide.
EMBODIED_CARBON_WHOLE_LIFE_INTENSITY	EMBODIED_CARBON_WHOLE_LIFE ÷ GROSS_FLOOR_AREA (m²)	kgCO₂e per m². Whole-life carbon on a comparable per-area basis. Checkpoint-wide.
ENERGY_USE_INTENSITY	ANNUAL_ENERGY_USE ÷ GROSS_FLOOR_AREA	kBtu per square foot per year — the energy use intensity (EUI), the standard operational-energy benchmark. Checkpoint-wide.
WATER_USE_INTENSITY	ANNUAL_WATER_USE ÷ GROSS_FLOOR_AREA	Gallons per square foot per year — the water use intensity (WUI). Checkpoint-wide.

Unit

Enum

A unit of measure a contributed value may be expressed in, grouped by dimension. A metric value's unit must match the dimension of its metric (an area unit for GROSS_FLOOR_AREA, a power unit for IT_LOAD_CAPACITY); incompatible pairings are rejected. The Metric table's canonical-unit column shows the unit each metric's values are normalized to for benchmarking.

CostCodeSystem

Enum

A classification system a cost line can be coded under (CostLine.codes). The two UniFormat levels are required on every line — the shared elemental taxonomy all market-data benchmarks are computed on — and a line may additionally carry a recognized standard (MasterFormat) or a member-defined system (CUSTOM, named in CostCode.systemLabel). This is the vocabulary that makes cost codes extensible: adding another recognized standard is one new value here, while a contributor's own systems need no schema change.
