This is an example brief. Its company, dates, budget, assignment and progress illustrate a project; they do not represent available or commissioned work. Proposals cannot be submitted.

The brief

The work and the intended result

A building-services team is replacing three rooftop units and wants an early view of how their support frames could align with the known structure. Compare two framing arrangements, show indicative load paths and list the information required for a detailed check. The fixed package includes one concept model, two layout sheets and one coordination meeting. Site verification, roof-capacity confirmation, connection design and construction approval are excluded.

What you’ll deliver

  • A source-drawing register and a clearly bounded assumptions note
  • Two support concepts with indicative load paths and equipment clearances
  • A concept model and two annotated layout sheets
  • A list of survey questions and calculations needed in the next design stage

Expertise needed

  • Experience coordinating small structural support frames with building services
  • Ability to identify where old drawings are insufficient evidence
  • Editable model or CAD exports alongside readable PDF drawings
  • Structural analysis
  • Steel design
  • BIM
  • Concept design

A running start

What’s already in place

  • Existing structural plans and recent roof photographs
  • Dimensions, masses and service-clearance envelopes for three units
  • Proposed lifting access and the building-services layout

Project milestones

To shape together
  1. 01

    Map the known structure

    Locate the three units against the supplied plans and record uncertainties in the existing-building information.

  2. 02

    Compare the support arrangements

    Develop two concepts with visible load paths and review their installation constraints.

  3. 03

    Prepare the detailed-design brief

    Hand over the chosen study direction with each unresolved dimension and structural question identified.

To agree before starting

A shared definition of done

Confirm the deliverables, review checks and response window together so everyone knows what a successful handover looks like.

Suggested acceptance criteria

  • Every agreed deliverable is included in the handover, in the agreed file formats.
  • Assumptions, limitations and open questions are documented alongside the work.
  • The project owner reviews the work against the brief and returns one consolidated feedback list before approval.

When the scope changes

Record the requested change, its reason and its effect on deliverables, budget and timing. Both parties agree the revised scope in writing before the additional work begins.
