Participation in a competition below the European thresholds - sectors (construction work) roofing work general description as an appendix to the list of services: roofing and plumbing work construction task: for the Catholic basilica "st. Lubentius" the repair of the side aisles, the upper guards with nave roof, crossing tower and transepts is planned for the year 2025 and 2026 as the second construction phase. The renovation work includes re-tiling the roof areas, repairing the damaged and weakened roof structures and flat ceiling beams, restoring the lead glazing and reworking the stone-faced facade areas with reworking the natural stone structure from the time of construction. Existing building: The Catholic basilica "st. Lubentius" is an important Romanesque building in an impressive location on a limestone outcrop high above the Lahn. The ensemble consists of several building sections which can only be accessed directly on foot. The immediate area around the basilica is surrounded by natural stone walls which form the end of the steeply sloping rock tableau to the east, south and west. Only the car park in front of the church tableau can be accessed from the north through the cramped building structure of the neighboring buildings. On the west side, below the bell towers, extends the former churchyard area with isolated old burial grounds. The southern buildings can only be reached on foot via the passage below the altar. The basilica and the adjacent chapels are a place of pilgrimage and are heavily frequented by visitors every day. Services will also take place during the construction period. The historically valuable parts of the building to be worked on, with different construction histories, are characterized by their roof structures, some of which have been preserved in their original form, which makes it possible to classify the components precisely in terms of construction time. - Roof over the central nave of the nave: oak, 1167 - Roof over the upper floor of the crossing: spruce, 1332 - Roof over the northern arm of the transept: oak, 1145 - Roof over the southern arm of the transept: spruce, 1813 - Lean-to roof of the northern aisle: oak, end of the 18th century - Lean-to roof of the southern aisle: spruce, mid-19th century. After the roof covering has been demolished, the historical roof structures will be reinforced in accordance with static requirements and in consultation with the State Office for Monument Preservation. On the stone-faced façade with its numerous natural stone structuring elements, the joint mortar will be removed and replaced. Damaged natural stone elements will be replicated. The window glazing is being removed for restoration purposes. The repair work on the historic roof structure is being carried out at the same time and requires close coordination with the commissioned natural stone company. The scaffolding of the components is being carried out in stages. In the first step, the northern and southern side roofs are being scaffolded and the slate roof covering with formwork substructure is being demolished. The roof structure, which has only been partially accessible up to now, is being structurally strengthened, formwork is being installed and pre-covered. The extent of the wood damage to the side roof structures will only be apparent once they have been exposed. The processing time is therefore currently difficult to estimate! The upper garden and the transepts with crossing towers will then be upgraded. The slate roof covering will be demolished across the entire surface, first on the nave roof. The existing formwork area is being enclosed with a weatherproof film. To work on the roof structure, 6-7 pairs of rafters are exposed on both sides in sections, statically reinforced and then re-formed and pre-covered. The transept roofs are only de-slated and repaired when the nave roof has been completely overhauled. The processing sections require close coordination between the carpenter and roofer trades. Roofing and plumbing work: The slate roof covering of the nave roof, as well as the side roofs and the roofs of the transepts were comprehensively examined by an expert in 2021. The coverings of different types of covering and age groups are clearly defective. However, the dismantling of the slate areas with new covering is already necessary due to the extensive repair of the damaged roof structures. The demolition of the slate roof covering must take place step by step. The demolition work must be carried out in various smaller construction phases. The work is weather dependent and must be carried out in direct consultation with the site manager. A demolition area is to be considered a daily performance including securing the site and weatherproofing. The construction site may not be left with an open surface "without prior notification and approval from the site manager".

Adaptive scaffolding and structures may be necessary! Information on the construction work: Construction site setup and safety work: The western Be at the adjacent former cemetery will continue to be made available to serve the construction areas of the II.ba. The access road, L/w = 30.00/4.50m including storage area, approx. L/w = 7.00 x 6.50m, on the green area of the churchyard was created with a gravel bed so that it is passable for small trucks. Scaffolding: Assembly platform: To the west of the south tower above the rock ledges, an assembly platform load class 3 (2kn/m²) has been erected as a working platform L/w=11.00/6.60m. The assembly platform is served from the lower storage area using a scaffolding lift for people and loads. Load capacity: 500 kg. The general construction power connection is provided on site on the assembly platform. The storage area and assembly platform are secured against unauthorized access by means of a construction fence. An appropriate key will be made available to the contractor. The work platform is to be raised as part of the Ii.ba Scaffolding: Construction site Ii.ba The components to be worked on are scaffolded using a W09 modular scaffolding of the contractor's choice in accordance with Dibt approval, Lk4 Din En12811-1, p = 3.0kn/m², 1 layer loaded, system coverings St/vh, adaptation to the nave wall with brackets, coverings with system-free planks 4.5x20/24/28 C24, 3-part side protection, bracing with system diagonals and system-free tubes Ro48.3x3.2 S235 in accordance with static requirements. The load is delivered via the existing west-side work platform, which is to be raised later. On both sides of the work platform platform, a 3-plank scaffolding run leads around the tower areas to scaffolding levels 5 (eaves of the south and north side aisles). All scaffolding levels are served by a passenger and goods lift. Scaffolding levels 7 and 9 will have work platforms on both sides in the lift area. To secure the interior ceiling and for work safety, a safety platform will be located inside the nave. The work platform must be built as a cantilever scaffold frame limited to the edge zones in order to be able to continue to guarantee attendance at church services. The upper work surface must be completely covered with a dust-reducing layer of bulkhead up to the wall surfaces and sealed with a soft connection (window compression tape). Material supply and disposal: Areas for material supply and car parking spaces in front of the church plateau are only available to a limited extent. The material can only be transported from the car park to the construction site via the gravel access area in the cemetery area. See the markings in the attached documents. Storage of materials outside of the areas provided for this purpose and on public areas is not permitted. Company vehicles are parked at the customer's own risk and in accordance with the applicable road traffic regulations. All costs for delivering materials, parking fees and any road traffic permits that may need to be applied for are to be borne by the customer and are covered by the standard prices. If public areas are used for material storage, the relevant registrations and permits must be obtained from the public order office of the city of Limburg at the customer's own risk and at cost. The additional storage areas must be cordoned off, illuminated and signposted in accordance with the road traffic regulations.
