Start from a brief

Paste something like this.

“We're fitting out a new 1,500 sqm office on the third floor of a multi-tenant building in Manchester for around 90 staff. It's a Cat B fit-out — open-plan desks, six meeting rooms, a boardroom, a tea point, a breakout area and reception. The landlord has handed over the shell and we need to be in by the end of Q3. Design is roughly agreed but we still need the landlord's licence to alter and to appoint a main contractor.”

That’s the before. Here’s the plan Ganttastic builds from it.

Typical timeline · 10-16 weeks on site (4-6 months end to end including design and procurement)

The construction fit-out plan.

An editable construction fit-out Gantt plan generated in Ganttastic, with task bars, dependencies, and milestones
  1. 1

    Design, approvals & procurement

    • Measured survey, space planning and test fits
    • Detailed design, specification and M&E design
    • Secure landlord's licence to alter and building control approval
    • Tender package, main contractor appointment and programme sign-off
    • Order long-lead items — glazed partitions, feature lighting, furniture, HVAC plant
  2. 2

    Site setup & strip-out

    • Site establishment, welfare, hoarding and floor/lift protection
    • Asbestos refurbishment & demolition survey and any licensed removal
    • Strip out existing partitions, ceilings, floor finishes and redundant M&E
    • Builder's work — core drilling, penetrations and structural openings
  3. 3

    First fix & M&E

    • Erect metal stud partitions and blockwork
    • First-fix electrical — containment, cabling and distribution boards
    • First-fix mechanical — ductwork, pipework and VRF/AC refrigerant lines
    • Data/comms cabling and fire alarm containment
    • Suspended ceiling grid, plasterboard and skim
  4. 4

    Second fix & finishes

    • Flooring — raised access floor, screed, carpet tiles and vinyl
    • Decoration — tape, joint, skim and paint
    • Second-fix electrical — accessories, light fittings and small power
    • Second-fix mechanical — grilles, diffusers, sanitaryware and taps
    • Joinery — tea point, reception desk, doors and glazed manifestation
  5. 5

    FF&E, IT & commissioning

    • Install furniture, workstations and storage
    • AV, IT network and access-control installation
    • Signage, branding and manifestation graphics
    • Commission M&E, air balancing and BMS controls
    • Fire alarm and emergency lighting commissioning
  6. 6

    Handover & completion

    • Snagging and defects rectification
    • Building control and fire authority sign-off / completion certificates
    • O&M manuals, as-built drawings and warranties
    • Builder's clean and practical completion walkround
    • Client occupation and defects liability period begins

Key dependencies

  • The landlord's licence to alter and building control approval must be in place before any works start on site — beginning without them risks stop notices and costly reinstatement.
  • Design has to be frozen early because bespoke joinery, glazed partitions, feature lighting and HVAC plant carry six-to-twelve-week lead times, so procurement runs in parallel with enabling works rather than after them.
  • On site the sequence is strict: strip-out before partitions; partitions and first-fix M&E complete and inspected before ceilings and boarding close them in; then second fix, finishes and FF&E.
  • M&E commissioning and air balancing can only begin once the space is weathertight, powered and clean, which is why it sits close to handover.

Timeline risks

  • Fit-outs most often slip on long-lead procurement and on latent conditions uncovered during strip-out — asbestos, redundant services or structural surprises the survey missed.
  • In occupied, multi-tenant buildings, restricted access, out-of-hours noise limits and goods-lift booking quietly erode the programme.
  • Protect the end date by ordering long-lead items at design freeze, holding a float week before commissioning, and never compressing M&E testing and snagging just to hit practical completion.
