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.

Create a project

Only the project name is required. Save now and fill the rest as the information arrives — an empty field is recorded as not yet known, never guessed.

1. Project identity
2. Building definition

A total is derived from the typical floor area only when you supply it. Incomplete floor data never produces a total.

3. Engineering basis
Available information

Ticked means available. Unticked means not recorded — the workspace will list it as missing rather than assuming it does not exist.

4. Project scope
5. Documents and missing information

Documents and the missing-information register are managed inside the workspace once the project exists.

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.

  1. 01

    Project Setup and Site Information

    Identity, building definition and engineering basis for one project.

    Supported

    No calculator attached · Project Setup

    • No dedicated site-information calculator; site data is entered as free text.
  2. 02

    Site Preparation, Survey and Earthworks

    Cut and fill, trenching, excavation volumes and site drainage.

    Partially supported

    4 existing calculators

    • No survey import or setting-out model; levels are entered manually.
    • No bulk earthwork optimisation or haulage planning.
  3. 03

    Foundations

    Bearing capacity, piles, settlement and footing volumes.

    Partially supported

    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.
  4. 04

    Below-Ground Structural Works

    Basement works, retaining structures and earth pressure.

    Partially supported

    4 existing calculators

    • No dedicated waterproofing area or membrane takeoff calculator (see stage 07).
    • No groundwater/hydrostatic design model beyond earth pressure.
  5. 05

    Above-Ground Structural Frame

    Beams, columns, slabs, stairs, reinforcement and formwork.

    Partially supported

    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.

  1. 06

    Masonry and Partitions

    Block and brick wall quantities by volume, area and thickness.

    Supported

    2 existing calculators

    • No block layout generator or mortar mix design tied to the block type.
  2. 07

    Waterproofing and Protection

    Waterproofing and protective areas to below-ground and wet elements.

    Partially supported

    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.
  3. 08

    Facades and Building Envelope

    Envelope areas, facade elements and roofing.

    Partially supported

    2 existing calculators

    • No curtain-wall or cladding engineering (anchors, brackets, deflection).
    • No thermal transmittance calculation.
  4. 09

    Interior Finishes

    Plaster, screeds, finishes and internal surface quantities.

    Partially supported

    3 existing calculators

    • No finish schedule import; areas are entered by hand.
  5. 10

    Metalwork, Joinery and Fixtures

    Structural and architectural metalwork, doors, windows and fixtures.

    Partially supported

    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.

  1. 11

    Electrical and Low-Current Systems

    Load, distribution, cable sizing, voltage drop and power quality.

    Partially supported

    7 existing calculators

    • No short-circuit study, protection coordination or arc-flash assessment.
    • No low-current/ELV design or containment coordination beyond conduit fill.
  2. 12

    Mechanical and Plumbing Systems

    HVAC loads, duct and pipe hydraulics, and plumbing demand.

    Partially supported

    13 existing calculators

    • No pipework layout or coordinated services model.
    • No equipment scheduling or energy model linked to the quantities.
  3. 13

    Fire Protection and Life Safety

    Fire water demand, egress and life-safety provisions.

    Partially supported

    2 existing calculators

    • No smoke control, sprinkler hydraulic design or detector layout.
    • Egress checks are indicative; the fire strategy remains the governing document.
  4. 14

    External Works and Utilities

    Site infrastructure, drainage, roads, culverts and attenuation.

    Partially supported

    7 existing calculators

    • No utility coordination model; buried services are entered manually.

Commercial & Project Controls

Quantity takeoff, cost, schedule and procurement.

  1. 15

    Final Quantity Takeoff and BOQ

    Consolidated quantities and the bill of quantities.

    Supported

    4 existing calculators · Construction Workflow (quantities and BOQ), BOQ takeoff workbook

  2. 16

    Cost Planning and Rate Analysis

    Rates, rate analysis components and the cost summary.

    Supported

    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.
  3. 17

    Construction Scheduling and Resource Planning

    Programme, durations, milestones and resource loading.

    Partially supported

    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.
  4. 18

    Procurement and Material Planning

    Material take-off, lead times and purchase requirements.

    Partially supported

    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.

  1. 19

    Inspection, Testing and Commissioning

    Test schedules, hold points and commissioning checks.

    Partially supported

    1 existing calculator

    • No document-control workflow or digital signature capture.
  2. 20

    Handover, Defects and Closeout

    Handover documentation, defects register and as-built records.

    Partially supported

    No calculator attached · Construction Workflow (handover)

    • No document management or as-built drawing store.
  3. 21

    Final Project Report and Archive

    The final engineering report and project archive.

    Partially supported

    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.
