Description

Dunamare Onderwijs is seeking a general contractor for a significant project at the Coornhert Lyceum in Haarlem. The work encompasses renovation, energy efficiency upgrades, and expansion of the existing school building. As the general contractor, you would be responsible for the overall management and execution of the entire project, including coordinating all sub-trades. This suggests a complex project involving multiple disciplines and potentially demanding logistical challenges inherent in working within an existing school environment.

The project's scope, involving renovation, upgrades, and expansion, indicates a substantial undertaking beyond simple maintenance. Bidders should anticipate a need for skilled labor across various trades, strong project management capabilities to handle the integration of different work streams, and experience with sustainable construction practices. The brief deadline (less than a month) between publication and submission also suggests the procuring entity expects a quick response and that potential bidders should have relevant experience that allows for a streamlined tender preparation.
