Germany – Architectural, engineering and planning services – Generalplanungsleistungen für die Sanierung und Instandsetzung der Tiefgarage Hospitalstraße 6, 55232 Alzey

The city of Alzey intends to award general planning services for the restoration of a structurally damaged car park in Hospitalstraße 6, 55232 Alzey. The subject of the measure is the planning, coordination, tendering, procurement support and project-supervisory accompaniment of the necessary structural and technical restoration and maintenance measures. The basis for the planning are the results of the existing investigation report as well as the damage patterns and recommendations for action identified therein. According to the available investigations, the car park has significant damage to the load-bearing reinforced concrete components, floor surfaces, ramps, stairwell connections and technical installations. The main causes of damage identified were chloride- and carbonation-induced reinforcement corrosion, leaks, cracking, hollow spaces and damage to surfaces and coatings; the need for restoration is imminent. The objective of the service to be awarded is to develop a technically sound, economical and permanently sustainable restoration concept as well as the complete planning and supervision of the implementation until the defect-free completion. The restoration is to be planned in such a way that the car park, after completion of the measure, will again meet the requirements for stability, durability, traffic safety and usability and will enable a further planned service life of 40 years. The car park is located in the northwest of the city of Alzey and is accessed via Hospitalstraße 6. It was built in 1980. The facility consists of one component, which was subsequently partially overbuilt with a three-storey residential and commercial building and a stone hall. The remaining areas above the car park are used as additional parking spaces. In total, there are around 176 car parking spaces available, which are distributed over two parking levels and are publicly accessible.
