Rope Bridge project at Middle East's biggest resort
Salwa Resort, Abu Samra, Qatar
The Dahab Mountain Water and Adventure Park - Salwa Beach Resort, Doha is set to become the Middle East’s premier destination beach resort, located on three million square meters of prime coastline in the southwest corner of Qatar less than 100 kilometres from Doha. With sweeping views of the Arabian Gulf, this ambitious 362-key property will feature a wide range of remarkable facilities, including three kilometres of private beach, a luxury marina and yacht club, a themed water park, a dive centre, cinemas, a shopping mall, an Arabian village, a 2,800 square meter spa and health club, and much more. The complex is expected to open in 2019. The Hilton Salwa Beach Resort & Villas, Qatar, is expected to be the largest of its kind in the Middle East and a first for Qatar.
The Salwa Resort is designed to become one of the largest resorts and residential projects in Qatar. Constructed on 257 acres of land in the Salwa area, the beach resort and villas is a massive project that includes a water park, marina, dive centre, cinemas, pools, a health club, spa and a considerable retail space. In addition to the rooms and suites in the main hotel building, the resort will also include two small ‘villages’ of family villas.

Installation plan:
✔️We supplied a two-man expert-installation team to work the following schedule - 14 work days, 2 travel days, 4 rest days plus 2 contingency days, plus two local staff provided by our client. Everything was prepared at our Surrey Hills workshop in the UK and shipped by 5-pallets air-freight because of the project timeline, but with a longer lead time could easily have been shipping container.
✔️We worked the math calculations for loads so that we could design and specify materials specific to the project.
Load Calculations for Salwa Resort, Abu Samra, Qatar Rope Bridge Project
✔️We designed a complete structural system based upon a load attachment swivel load ring that rotates through 360º and pivots 90º - each bridge system could work load-ring to load-ring and 6 at each end/12 in total, in the knowledge that we have a certificated and load tested unit proof tested to 2.5 times the weight load limit. We also designed and fabricated a steel bracket attachment for the load-rings that would be either welded to structural steel beams or fixed to concrete using a Hiliti® threaded rod and compound adhesive system. Hilti® were also engaged on-site to undertake ‘pull-out’ load tests on installed systems so that we had complete provenance of certification through accredited services.
✔️We researched rope systems and worked closely with Southern Ropes to design an ‘all-rope’ design with break-loads in excess of all calculations plus a safety ratio. From swivel load ring to structural rope we employed rope ‘Soft Shackles’ load-tested and certificated to 15 tonnes and Super Ropes braided in manilla colour fabric load-tested and certified to 8.4 tonnes.

✔️We pre-produced deck board ‘slats’ using 1200x220x45mm, C24 and Celcure treated timbers, with rounded edges on all faces and pre-routed rope channels on the reverse. We also screw-fixed anti-slip surfaces to all deck boards.

✔️We introduced a hemp coloured polypropylene and high tenacity safety netting with a mesh break-load at 3.2kN to the sides and above through each of the Rope Bridges and around the Scramble Net Bridge, Net Tunnel and ‘Dead Tree’ balustrades.
Rope Bridge Safety Netting Data Sheet
✔️We used 12mm polyhemp for frapping and dressing, particularly on the Rope Bridges for friction-weave and hand-weaved balustrade rope work, with a linear strength of around 1.4 tonnes and an average of 37 friction knots every 1m of Rope Bridge.
