  architettura, costruzione, garante dei costi sia



Keytek is a service company whose purpose is to ensure the execution of real estate projects by guaranteeing cost and quality of construction in partnership with its clients and their contractors. We place at your disposal a team highly experienced in the technical and financial aspects of building construction. Because we take a detached view of the cost, quality and planning of projects, we are able to monitor the implementation phases in a neutral way and guarantee a cover in the event of a cost overrun. We are a safe and transparent alternative to the general contractor model and are recommended by the SIA (Swiss Society of Engineers and Architects) (an SIA guarantee contract). Some of our prime clients are project owners, banks, architects and investors in real estate and construction.
