Restricted invitation to tender with public participation competition VOB/A Renovation of an oven Oven construction and masonry work The existing oven is a brick natural stone oven for wood firing on the stove surface. The usable baking surface is approx. 2.15 m deep and approx. 1.70 m wide at its widest point. The baking surface is made of fireclay panels. The oven ceiling is a self-supporting vault made of fireclay bricks in the standard format (approx. 64 x 125 x 250 mm), the vault thickness is 250 mm. - Demolition of the existing oven, creation of a foundation. - Construction and commissioning of a natural stone oven with wood firing with approx. 4 m² baking surface in compliance with the technical rules for oven and air heating construction (trol 2022) including all masonry work. - If necessary, renovation work on the existing chimney or construction of a new chimney in consultation with the responsible district master chimney sweep.

Restricted invitation to tender with public participation competition Vob/a Municipality of Waldsolms, new construction of a drinking water treatment plant in the Ot Kraftsolms, Lot 1 The municipality of Waldsolms intends to build a new drinking water treatment plant and connect it to the local network at the Kraftsolms location. General description: The new construction of the water treatment plant is planned with a steel hall (12.60x7.60m) and a settling shaft. The technology of the treatment plant will be installed in a steel hall. The hall is founded on a reinforced concrete floor slab with rising 2.50m high reinforced concrete walls. The hall is planned as a steel structure and a pent roof (total height: 5-7m) made of insulated sandwich elements. The pipes in the new steel hall will be made of stainless steel (approx. 70 m, up to DN 200). A new flushing water pipe (DN 200, approx. 8 m) leads from the new water treatment plant to the settling shaft. The settling shaft made of prefabricated reinforced concrete parts for flushing water pretreatment has a usable volume of approx. 90 m³. The shaft has external dimensions of (lxwxh) 9.75 MX 4.00 MX 3.40 m. In addition, approx. 55 m of rainwater pipe from the downpipes and from the drain pipe of the settling shaft (DN 100 - 200) are planned. Also, approx. 85 m of raw water pipe (DA 110) from the well to the treatment plant and approx. 900 m of clean water pipe (DA 110) from the treatment plant to the connection point in Kraftsolms will be manufactured. A natural drainage ditch to the nearby Minetbach with a length of around 40 m is also to be created. The civil engineering work includes the construction of the outdoor area. This includes around 120 m² of paved area and around 110 m of fencing with a gate and door system. The work will be divided into two lots. Lot 1: earthworks, reinforced concrete work, pipeline, outdoor facilities, steel hall, drainage channel (lot 2: mechanical engineering is not the subject of this competition)

Restricted invitation to tender with public participation competition Vob/a Municipality of Waldsolms, new construction of a drinking water treatment plant in the Ot Kraftsolms, Lot 2 (mechanical engineering) The municipality of Waldsolms intends to build a new drinking water treatment plant and connect it to the local network at the Kraftsolms location. General description: The new construction of the water treatment plant is planned with a steel hall (12.60mx7.60mx5.00-7.00m high) and a settling shaft. The water treatment (throughput range 9-13m³/h) consists of a 3-stage process. In the first treatment stage, the iron compounds are removed. For this purpose, the raw water is aerated with an aerator candle which is installed in a stainless steel pipe section DN 100. The raw water is then filtered in a filter vessel (pressure filtration). The required diameter of the filter vessel is 1.60 m and the jacket height is 3.00 m. After the iron has been removed, the water is physically deacidified in a flat bed aerator using the countercurrent process in the second step. The water is temporarily stored in a small pump reservoir with a volume of around 1.5 m³. In the third treatment step, the manganese is removed. To demanganize the water, analogous to deferrization, is filtered in a filter vessel (pressure filtration). After demanganization, the treated drinking water is temporarily stored in a storage tank with a volume of around 15 m³. On the one hand, this serves as a template for the three pumps (2 in parallel operation, 1 redundant), which pump the drinking water via the planned drinking water connection line into the Kraftsolms pipeline network and further into the Kraftsolms elevated tank. On the other hand, the stacking tank serves as a water template for backwashing the pressure filtration. The resulting flushing waste water and the initial filtrate are taken to a sedimentation plant. The work is divided into two sections. Here, section 2: mechanical engineering (section 1: earthworks, reinforced concrete work, pipeline, outdoor facilities, steel hall, drainage channel is not the subject of this competition)
