## Abu Dhabi City Municipality — Circular No. 001/2021, Safety requirement for tower cranes

The circular’s first page is titled **“Safety requirement for tower cranes”** and applies to consultants, contractors, and developers working in the building and construction sector in Abu Dhabi City. It explicitly states the following requirements:

| Control area | Browser-verified finding |
|---|---|
| Permit | A permit to install the tower crane must be obtained from Abu Dhabi City Municipality for all types of cranes, including self-erecting cranes, in accordance with approved MEPS drawings. |
| Erection | The erection company and technical inspection provider must confirm that the erection permit was issued and installation follows approved drawings and specifications. |
| Site boundary | Tower cranes must be erected wholly within the project plot boundary. All lifting-operational crane parts, including counterweight and boom, must not exceed the project fence/plot limit. |
| Multi-crane interface | Tower cranes must be located so as not to create collision risk with other cranes in all operating configurations. |
| Maintenance | Monthly inspection and maintenance are to be carried out by a specialized third-party maintenance company, following manufacturer recommendations and considering age and condition; reports must be available on request. |
| Pre-use inspection | Daily and weekly inspection must be conducted by a competent person; reports must be available on request. |

The official DCAA crane-operation service URL was opened. The public browser view did not render the service details beyond the site shell; therefore, the final package will state the DCAA approval requirement as an authority-verification item and will not reproduce unverified height, lighting, or submission thresholds from secondary sources.

## Extracted official-source findings

| Source | Verified finding used in final package | Evidence boundary |
|---|---|---|
| MoIAT / ENAS ETR 06 | Tower cranes are within Class A1 powered lifting machines. The document defines inspection-body competence and sets a 12-month mandatory inspection frequency for Class A1 and a six-month interval for Class C lifting accessories. It specifies certificate contents and says authorities may reject incomplete third-party certificates. It also notes full NDT every two years during normal inspection and a 25% SWL reduction for tower cranes aged 20 years. | ETR 06 is dated 11 August 2014. The project team must check current authority acceptance and whether a more recent condition or circular applies. |
| Sharjah City Municipality service catalogue | The service is explicitly for requesting issuance or renewal of a tower-crane permit to install and use a tower crane and equipment within site boundaries. | Public extract did not expose document checklist or technical conditions; confirm them directly with SCM. |
| Trakhees guideline G20 | Requires RA for mechanical lifts; SLI over 1 tonne; anti-collision where two or more cranes may collide; anemometer on highest crane; manufacturer wind limit; 12-month equipment testing and six-month lifting-accessory examination; certification for crane operator, signaller and slinger by approved third parties; recorded weekly service inspection; lifting manager and supervisor for critical lifts; radio communication if no line of sight or crane exceeds 35 m ground-to-cab; tested climbing frames; emergency procedure. | Apply only where Trakhees is the governing authority, or as a sound control benchmark if the local authority accepts it. |
| Ajman Municipality service catalogue | AJ municipality offers a compliance-with-environmental-and-safety-requirements certificate service for facilities requested by local or federal authorities. | The page is not a crane-specific approval instrument; it does not validate a specific crane permit, inspection frequency, operator licence, or wind limit. |
| Ras Al Khaimah Municipality ZP07 | Arrangement and Mobilization Permit can authorize preparation tasks including bringing in cranes or heavy machinery before the building permit is secured. Required inputs include site plan, trade licence and site-service clearance NOCs; activities must remain inside plot boundaries; validity is 12 months. | This source is about mobilization, not the whole tower-crane lifecycle. A separate construction/structural and HSE approval may still apply. |
| Umm Al Quwain service catalogue | Building-permit service requires contractor licence, NOCs including Civil Defence and utilities where necessary, location inspection form, reports/drawings and engineering approval. | No publicly accessible UAQ tower-crane service specification was located; verify crane-specific submission and inspection expectations with Engineering Affairs and Civil Defence. |
