3. GENERAL SCOPE OF WORK OF BASE-BID
The works include the conversion of one classroom into separate bathrooms for boys and girls, including showers, together with the replacement of exterior doors and windows and the application of a thermal façade systems, as required by Montenegrin regulations and as detailed in this document
3.1. Replacement of all wooden windows (PVC – double glazing)
The contract includes the replacement of all exterior wooden windows of the school.
The windows shall comply with Montenegro regulations for public educational facilities. As a minimum the windows shall be manufactured with PVC profile and double thermally insulated glazing. Minimum requirement is PVC profiles with 5 chambers and double glazing. Each glazing shall have a minimum thickness of 6 mm.
The contractor shall completely remove all wooden windows, including the wooden anchors and the wooden sills and trims. All wood from existing wooden windows shall be removed as part of this contract. The contractor shall make the required adjustments and repairs to the window opening on the walls before installing the new windows. The contractor is responsible to visit the site, to take note of the existing conditions of the window openings and to make all required measurements to quantify the amount of work required by this contract. The contractor is responsible to repair all internal surfaces damaged by the replacement of the wooden windows.
This will be significantly relevant when removing the existing window internal sills. The contractor shall completely remove the exterior wood windows, including all framing, trims, anchors and supports.
The new windows shall operate similar as the existing ones. In other words: if a window has 2 operational panels, the new windows shall have two operational panels of approximately similar dimensions, but the opening panels/leaves of the windows shall open vertically and horizontally.
For estimating purposes, the contractor shall estimate that 50% of the window surfaces shall be operational (horizontally and vertically)
The new PVC windows shall be perfectly finished inside and outside. The joints between the building and the windows shall be perfectly sealed as seen in pictures below for a typical installation (typical “yellow” foam cannot be visible). Contractor to provide PVC sill inside as seen in the pictures below and new outside sills made of aluminum or other approved material (i.e.
natural marble or exterior rated special ceramic tiles or galvanize metal sheet).
The windows of the room to be converted in to bathrooms need to be provided with non-transparent glazing and with mosquito nets. The use of a film to make the glass non-transparent is not authorized, but at least 1 of the 2 panes shall be manufactured as non-transparent.
New windows and doors are to be made of highly valuable PVC five chamber profiles that must be of certain thickness (min. 3,5 mm) and with reinforced galvanized steel profiles. Profile should be fully in compliance with RALA quality standard.
Coefficient of thermal conductivity of profile package with metal reinforcement (according to DIN EN 12412-2) less than 1.4 W/m2K). Filling should be double layered glass IZO /20 mm/ (double flat transparent glass with a vacuum between, d=6+12+6 mm).
Inner glass is low emission – LOW E – 1,1W/m2K while the outer is classic - FLOAT.
Sealing is to be done with epoxy rubber (in line with EN410 and EN 673 , Ug=do 2.0 W/m2 K).
Joinery to be supplied with high quality replaceable seals, high quality shackles based on nickel and AL alloys, handles, doorknobs and keys.
All PVC joinery is to be done in line with schemes, in white color. The plan is to have natural flow of air when windows are closed, through especially constructed elements in the frame of the window, type Regel Air, or in some other way, in line with DIN and EU norms. Number and size of elements depends on the size of the window - minimum of two units. No elements should be put in fixed windows and over-lights. Windows should be tightened with wall screws depth 50 mm.
Sealing between wall and window frame should be done with polyurethane foam. Quality certified shackle should enable opening in line with the provided scheme. On the outer side, set an outer bench made of prefabricated aluminium profiles. They are set in the whole width of the window and light box in the prescribed bleed around current facade walls, including the intervention on the facade - construction of thermally insulated facade - the bleed should be six cm more than prescribed bleed. When installing exterior window sill, the sides must lean on the wall, and the part of the facade that is damaged must be fixed. The sill should be tightened with at least two screws in the field. They can be direct or indirect. On the interior side, place parapet benches PVC profile in white color, all in line with producer specifications and joinery schemes. Investor or supervision body (with agreement from investor or contracting authority) can chose to change the color of facade joinery.
Certificates to be submitted by the bidder for all joinery:
• Systematic testing of windows, 14351-1 and B 5300
• Certificate for air permeability EN 12207 - Class 4
• Certificate for water resistance EN 12208 - Class E 900 A

• Certificate on the coefficient of warmth conductivity DIN EN 12412-2
• Glass certificate EN 673
• Shackles certificate V ENV 1627-1630, resistance class 3
Prior to production of joinery (windows) that is done in a larger series, it is necessary to make and install a complete typical window that will, upon removal of all possible objections, be recorded and certified and accepted by the Contracting Officer Representative.
