Engineering drawings for authority approval

A permit is only as good as the drawing set behind it. We prepare and coordinate architectural, structural, MEP and fire & life safety drawings that reviewers can check quickly, so your application spends less time in comment rounds.

Every authority in Dubai reviews drawings, not intentions. Whether the file goes to Dubai Municipality, Trakhees, the Dubai Development Authority or a free zone, the reviewer sees only what is on the sheets, and anything missing, unclear or contradictory comes back as a comment.

This page is about the drawing package itself: what goes into it, which standards it must meet, and how it travels from your brief to an approved, stamped set. If you already know which permit you need, the matching permit page explains the approval route. Here we focus on producing drawings that survive review.

We are an independent consultancy. The authorities alone decide whether to approve a design. Our role is to prepare drawings that are complete, coordinated and compliant, and to manage the revisions until the set is accepted.

What an authority drawing package contains

"Engineering drawings" covers several disciplines that have to agree with each other. A typical package for a building permit, modification or fit-out approval brings together the following sets. Not every project needs every one, and smaller works may need only two or three.

Architectural

Site plan with setbacks, floor plans, roof plan, elevations, sections, area statements and door and window schedules. For alterations, clearly marked existing, demolished and proposed elements.

Structural

Foundation layouts, column and beam schedules, slab details and the supporting calculations. For changes to an existing building, a check of the structure that will carry the new loads.

MEP

Electrical layouts and load schedules, water supply and drainage, air-conditioning and ventilation, and thermal insulation details. See our MEP design service for the detail.

Fire & life safety

Fire alarm, firefighting and voice evacuation layouts, escape routes and compartmentation, prepared for Civil Defence review where the building or use requires it.

Alongside the sheets sit the supporting documents: ownership proof, the official site plan, developer NOCs, consultant and contractor appointments and, where the building type calls for it, soil investigation and survey data. A drawing set that cites a plot area different from the site plan, or a use different from the trade licence, will stall however good the design is.

The standards drawings are checked against

Reviewers don't assess drawings against general good practice. They check them against specific codes, and the drawings should make compliance easy to see.

StandardWhat it coversWhere it shows up in the drawings
Dubai Building Code (2021 edition)Minimum design requirements across architecture, accessibility, vertical transport, building envelope, structure, incoming utilities, indoor environment, security and villas. Mandatory across Dubai under Decree No. 45 of 2021.Room sizes, stair and corridor widths, accessible routes, envelope build-ups, structural design basis, utility rooms
Al Sa'fat green building systemSustainability requirements. New buildings must reach at least the Silver Sa'fa level.Insulation and glazing specifications, U-value calculations, water and energy measures
UAE Fire and Life Safety Code of PracticeThe fire code Dubai Civil Defence applies to fire alarm, firefighting, evacuation and fire separation.Fire and life safety layouts, exit widths and travel distances, fire-rated construction
Service authority regulationsDEWA electricity and water requirements, plus drainage, district cooling and telecoms where they apply.Load schedules, meter and substation rooms, connection points
Developer and community guidelinesAppearance, height, materials and boundary rules in master communities.Elevations, materials schedules, 3D views

The Dubai Building Code is split into Parts A to K. Part A sets out the general rules and how to navigate the code. The rest are themed: Part B architecture, C accessibility, D vertical transportation, E building envelope, F structure, G incoming utilities, H indoor environment, J security and K villas. Our Dubai Building Code explainer gives a plain-English tour.

Free zones too: the Dubai Building Code applies emirate-wide, including free zones. Authorities such as Trakhees also publish their own regulations, which apply in their jurisdiction alongside it.

Drawings for each authority

The same building can need slightly different presentation depending on who reviews it. We confirm the permit authority from the plot's site plan before drawing anything, because the route affects both the format and the order of submissions.

  • Dubai Municipality handles most mainland plots through the Building in Dubai platform, which uses BIM-based automated checks for suitable submissions. Clean, consistently layered models and drawings help here.
  • Trakhees covers land owned by PCFC, Dubai World and their subsidiaries, including many Nakheel areas, and applies its own published building regulations alongside the Dubai Building Code.
  • Dubai Development Authority reviews projects in its zones, such as the TECOM business parks.
  • Civil Defence and DEWA review their parts of the package on almost every project, either directly or as NOCs feeding the main permit.

How we prepare and submit a drawing package

Brief, records and site check

We collect the title deed, site plan, any existing approved drawings and the developer's guidelines, and visit the site. If the existing drawings don't match what is built, we recommend an as-built survey before design starts.

You + our team

Compliance framework

We list the rules that will govern the design: zoning, setbacks, height, permitted use, parking, and the code parts and authority guidelines that apply. This becomes the checklist for every discipline.

Our team

Concept and coordination

Architectural layouts are developed first, then checked with the structural and MEP designers so shafts, risers, plant rooms and structure fit before detailing begins.

Design team

Developer NOC where applicable

In master communities the developer usually reviews the design before the authority does. We submit and close out developer comments first.

Consultant · developer

Detailed drawings and calculations

Each discipline completes its sheets, schedules and calculations. We run an internal cross-check so areas, levels, grid lines and room names agree on every sheet.

Design team

Submission and comments

The package is submitted through the authority's portal by a registered consultant. We track comments from each department and service authority and return revised sheets with a clear response sheet.

Registered consultant

Approved set and site use

The stamped drawings become the contractor's reference for construction and inspections, and later the basis for the completion certificate.

What you receive

  • Authority drawing setDiscipline drawings formatted for the relevant portal, with title blocks, revision history and consistent sheet numbering.
  • CalculationsStructural calculations, electrical load schedules and thermal calculations where the submission needs them.
  • Area statementsBuilt-up area, gross floor area and plot coverage tables that match the drawings and the site plan.
  • Compliance notesA short record of how the design meets key code and guideline requirements, useful when a reviewer queries a point.
  • Comment response sheetsEach reviewer comment listed with the change made and the sheet reference.
  • Approved drawingsThe final stamped set, organised for your contractor and your property records.

What affects design time and cost

We quote design work after seeing the brief, because the effort varies widely. A non-structural office fit-out can need a small set of architectural, MEP and fire layouts. A new multi-storey building needs a full coordinated package and several review stages. The main factors are:

  • Number of disciplines. Each added discipline adds design, coordination and review time.
  • Quality of existing records. Missing or inaccurate approved drawings mean surveying first.
  • Number of reviewers. Developer, permit authority, Civil Defence, DEWA and others each review and comment separately.
  • Use and occupancy. Food, health, assembly and storage uses carry extra fire and services requirements.
  • Design changes after submission. Changing the brief mid-review restarts parts of the process.

Authority fees are paid to the authorities and listed separately from our fee in every quotation.

Drawing problems that cause comments

Most comment rounds trace back to a handful of avoidable issues. Our article on architectural mistakes that delay approval goes into more detail.

  • Numbers that don't agree. The plot area, built-up area or number of floors differs between the area table, the plans and the application form.
  • Disciplines out of step. The MEP layout shows a shaft the architect has moved, or the structure has a beam through a duct route.
  • Unclear alterations. Modification drawings that don't separate existing, removed and new elements.
  • Missing fire strategy. Escape routes and fire separation left for later, then forcing layout changes after Civil Defence review.
  • Ignoring the site plan. Designing from a sketch rather than the official setbacks, height limit and permitted use.
  • Outdated templates. Reusing an old project's notes and specifications that reference superseded rules.

Engineering drawing FAQs

Often, yes. We review them against the code, the site plan and the authority's requirements and tell you what needs changing. Drawings must still be submitted by a consultant registered with the relevant authority.

Usually architectural layouts, MEP layouts and fire and life safety drawings, plus any landlord or developer requirements. Structural drawings are needed only if loads or structure change. The exact list depends on the authority and the use.

The Dubai Building Code is mandatory across the emirate, including free zones. Some authorities, such as Trakhees, also apply their own published regulations, and developers add community guidelines.

The authority or developer may hold copies. If not, or if the building has changed, an as-built survey produces accurate drawings that can support a new application or regularisation.

No. Approval is the authority's decision. Complete, coordinated drawings reduce comment rounds and avoid the most common reasons for delay.
