Construction Project Workspace
One project, one building definition, one set of quantities. Work the lifecycle in guided order or open any stage directly. Nothing is invented: where a stage has no engineering support yet, it says so and names what is missing.

Reference example — 30 floors, 3 basements
A worked demonstration driven by the real calculation engines and the real quantity pipeline. It is clearly labelled demonstration data and is never merged into a project you created.

The complete construction lifecycle
All 21 target stages are listed. Where a stage has no engineering support yet, the gap is named rather than hidden — this map is the roadmap, not a claim of coverage.
Definition & Early Works
Project definition, ground works, foundations and structure.
- 01Supported
Project Setup and Site Information
Identity, building definition and engineering basis for one project.
No calculator attached · Project Setup
- No dedicated site-information calculator; site data is entered as free text.
- 02Partially supported
Site Preparation, Survey and Earthworks
Cut and fill, trenching, excavation volumes and site drainage.
4 existing calculators
- No survey import or setting-out model; levels are entered manually.
- No bulk earthwork optimisation or haulage planning.
- 03Partially supported
Foundations
Bearing capacity, piles, settlement and footing volumes.
6 existing calculators
- Soil properties are user-supplied; the repository holds no soil database and will not invent one.
- No pile group settlement or negative skin friction analysis.
- No automatic reinforcement for foundations — see the rebar stage.
- 04Partially supported
Below-Ground Structural Works
Basement works, retaining structures and earth pressure.
4 existing calculators
- No dedicated waterproofing area or membrane takeoff calculator (see stage 07).
- No groundwater/hydrostatic design model beyond earth pressure.
- 05Partially supported
Above-Ground Structural Frame
Beams, columns, slabs, stairs, reinforcement and formwork.
14 existing calculators
- No automatic reinforcement percentage rule. Bar schedules must be supplied by the engineer; a percentage would be a fabricated design parameter.
- Member design checks are capacity checks, not a full code design routine.
Envelope & Internal Construction
Masonry, protection, envelope, finishes and joinery.
- 06Supported
Masonry and Partitions
Block and brick wall quantities by volume, area and thickness.
2 existing calculators
- No block layout generator or mortar mix design tied to the block type.
- 07Partially supported
Waterproofing and Protection
Waterproofing and protective areas to below-ground and wet elements.
3 existing calculators
- Material quantity stays unresolved until the engineer enters the coverage rate published for the selected product. No rate database exists and none is invented.
- Lap allowance, wastage, upstands, terminations and penetrations are not modelled.
- The takeoff does not confirm that a given surface is appropriate to waterproof — that is a design decision.
- 08Partially supported
Facades and Building Envelope
Envelope areas, facade elements and roofing.
2 existing calculators
- No curtain-wall or cladding engineering (anchors, brackets, deflection).
- No thermal transmittance calculation.
- 09Partially supported
Interior Finishes
Plaster, screeds, finishes and internal surface quantities.
3 existing calculators
- No finish schedule import; areas are entered by hand.
- 10Partially supported
Metalwork, Joinery and Fixtures
Structural and architectural metalwork, doors, windows and fixtures.
4 existing calculators
- This is a QUANTITY SCHEDULE. It does not establish a manufacturing specification, a bill of materials, hardware, finishes or fire rating.
- Handrail and balustrade structural adequacy is a design check against the applicable code and is not performed.
- No product, hardware or glazing selection is implied.
Building Services & External Works
Electrical, mechanical, plumbing, fire and external works.
- 11Partially supported
Electrical and Low-Current Systems
Load, distribution, cable sizing, voltage drop and power quality.
7 existing calculators
- No short-circuit study, protection coordination or arc-flash assessment.
- No low-current/ELV design or containment coordination beyond conduit fill.
- 12Partially supported
Mechanical and Plumbing Systems
HVAC loads, duct and pipe hydraulics, and plumbing demand.
13 existing calculators
- No pipework layout or coordinated services model.
- No equipment scheduling or energy model linked to the quantities.
- 13Partially supported
Fire Protection and Life Safety
Fire water demand, egress and life-safety provisions.
2 existing calculators
- No smoke control, sprinkler hydraulic design or detector layout.
- Egress checks are indicative; the fire strategy remains the governing document.
- 14Partially supported
External Works and Utilities
Site infrastructure, drainage, roads, culverts and attenuation.
7 existing calculators
- No utility coordination model; buried services are entered manually.
Commercial & Project Controls
Quantity takeoff, cost, schedule and procurement.
- 15Supported
Final Quantity Takeoff and BOQ
Consolidated quantities and the bill of quantities.
4 existing calculators · Construction Workflow (quantities and BOQ), BOQ takeoff workbook
- 16Supported
Cost Planning and Rate Analysis
Rates, rate analysis components and the cost summary.
3 existing calculators · Construction Workflow (rates and cost), Rate analysis workbook
- Rates are user-provided. The repository holds no market price database and will not fabricate one.
- A partially priced BOQ is reported as a known-cost figure, never as a project total.
- 17Partially supported
Construction Scheduling and Resource Planning
Programme, durations, milestones and resource loading.
No calculator attached · Construction Workflow (planning)
- No critical-path or resource-levelling engine; the schedule is a derived list, not a full CPM solver.
- No productivity factors are assumed anywhere; durations are engineer-supplied.
- 18Partially supported
Procurement and Material Planning
Material take-off, lead times and purchase requirements.
No calculator attached · Project Workspace (procurement register), Construction Workflow (deliverables)
- No supplier, vendor, market-price or lead-time database exists, and none is invented. Supplier, quotation and required-date fields stay unknown until the engineer enters them.
- No purchase-order workflow and no stock or availability tracking.
- Quotation comparison is only possible once two real quotations have been entered; it never substitutes a market figure.
Completion & Handover
Inspection, commissioning, handover and closeout.
- 19Partially supported
Inspection, Testing and Commissioning
Test schedules, hold points and commissioning checks.
1 existing calculator
- No document-control workflow or digital signature capture.
- 20Partially supported
Handover, Defects and Closeout
Handover documentation, defects register and as-built records.
No calculator attached · Construction Workflow (handover)
- No document management or as-built drawing store.
- 21Partially supported
Final Project Report and Archive
The final engineering report and project archive.
No calculator attached · Construction Workflow (report and export)
- Export is JSON, CSV and browser print-to-PDF; runtime XLSX export is deferred in the existing code.
