The quality requirements of such a discerning client base are amongst the most demanding in the world. Often with a brief to achieve excellence, this requires an extensive range of specialist skills. Yahya Construction retains a full skills capability consisting of specialist carvers, joiners, marble, tiles and mosaic craftsmen, decorators, and gilders. These craftsmen have been recruited over the past 20 – 25 years and many have had a long service with the company. Each has been carefully selected. The selection process is so exacting that only a handful of craftsmen can be recruited each year to join the elite Yahya Construction team. Many of the craftsmen are second generation employees of Yahya Construction LLC.

Yahya Construction’s dedicated team of tradesmen is managed by highly experienced supervisors to ensure that tight tolerances on the basic structure are met. This team is fully aware of the demands of specialist finishes and work accordingly, each individual taking pride in the high level of finish he creates.

Yahya Construction Project team’s knowledge and experience of marble, gilding, furniture and joinery is often a valuable source of expertise welcomed by the architects and clients. Furniture and specialist joinery detailing is undertaken by the dedicated draughting team. Mock-ups of marble, joinery, and furniture and specialist decoration are also prepared to give the client a 3 dimensional perspective before finalizing the design.

All these activities are progressed in the early stages of the building process so that material sourcing requirements can be identified well in advance, minimizing any disruption to the contract programme.

Quality design developing staff are using latest computer CAD software for workshop drawings exchanged electronically for approval, prior to starting the production process.
