3.3.5. Interior Doors

Provide interior doors of either Glass Reinforced Polyester (GRP) solid doors and frames or solid hard wood construction at the Range Operations Center.

A modern composite laminate, GRP is a versatile and well proven construction material that has been in use for over 50 years in a huge variety of applications. GRP is an inherently dent resistant laminate, able to withstand knocks and blows that would easily permanently deform and damage a traditional steel door. Unlike steel, GRP door panels will not rust or corrode. Unlike wood, GRP door panels will not shrink, swell, warp or twist and do not require the regular attention needed to ensure a wood door retains its good looks.

Solid hard wood requires the doors to be made with solid core hard wood. Hard wood is defined as the wood from a broadleaved tree (such as oak, ash, or beech) as distinguished from that of conifers.

General requirements for interior doors:

- All doors shall be installed without bottom thresholds

- All doors to be installed with heavy duty stainless-steel hinges and stainless-steel handles

- All doors shall be designed to resist a vertical force of 200 kg without any deflection

- All doors to be lockable

- All doors to be provided with professional door signs. Contractor to coordinate door signage with Beneficiary and NAVFAC COR.

Interior doors separating toilets and/or sink areas at the Public Toilets/Latrine facility can either be interior doors with louvers at the bottom for ventilation or HDPE toilet partitions, with properties durable for use in an exterior latrine facility, mold resistant, corrosion resistant, and graffiti resistant.

Hardware for the doors: All doors shall be provided with stainless steel locks, stainless steel handles, stainless-steel heavy-duty hinges, door stops, and all required accessories. The Contractor shall provide a master key system.

Provide Door Signs for each door that identify the room number and use of that room (i.e. Mechanical Room). Coordinate sign type for exterior and interior use based on door signage is adjacent to.

Ben Ghilouf, Tunisia

3.3.6. Exterior Doors

The Contractor shall provide either hollow metal or aluminum doors at each entrance to the Range Operations Center, Public Toilets/Latrine facility, and Covered Training Area. Exterior doors shall be insulated and provided with a lite (window) to allow for viewing into the facility. Door lite shall have a mesh security layer.

The Contractor shall provide either PVC framed or aluminum doors at each entrance to the facility and at each distinct exterior room.

Ben Ghilouf, Tunisia

Example entrance door.

Example entrance door.

The number and size of exterior doors shall be designed by the Contractor’s architect. At a minimum, there shall be a main entrance door to the building and a second door that opens to the rear of the building.

Provide emergency exits to comply with Tunisian code. All entrance and exit doors shall open to the exterior.

Exterior doors shall be designed and built with the following minimum requirements:

- European standard aluminum profiles with break in the thermal bridge with three rubber dust protection seals

- With triple glazing in the upper half, like the ones specified for exterior windows

- With required locks and anti-panic hardware, all made of stainless steel

- Provided with door closers and door stops to avoid damages by users

- Aluminum profiles shall be minimum 8 cm wide and minimum of 1.8 kg/m (heavy duty)

- All exterior doors to be lockable. Coordinate lock system used with Beneficiary to provide compatible system to their existing

3.3.7. Ceilings

Provide white-painted ceilings in Range Operations Center and Public Toilets/Latrines. Provide exposed sandwich panels in Covered Training Area. Paint finish should match that of walls, or selected color by Beneficiary and NAVFAC COR.

3.3.8. Flooring

Ben Ghilouf, Tunisia

WON: 1702432

For the Public Toilets/Latrines, provide new homogeneous porcelain stoneware floors. Porcelain stoneware shall have the following characteristics and be coordinated with the sealed concrete floor:

- Thickness not less than 8mm

- Provide ‘Grès’ Porcelain Stoneware. Grès stoneware is a compact, hard, colored and non-porous body

- Include matching wall base board of same model as flooring tile. Floor tiles may not be cut to be used as base board

- Tiles shall be of homogeneous (non-glazed) material: This means that all the material of the tile is made of the same material. If we cut a tile, there would be no difference between different layers of the tile. The word “grès” means that the ceramic body of the tile is extremely vitrified, that is to say compact, hence the exceptional great resistance. The result is a lean clay body, little refractory, fired in a kiln (at 1200-1400 C°) until it reaches a non-porous vitrification and a complete water-proofing.

- Scratch hardness of surface (Mohs) >8 (according to EN101)

- Resistant to impacts: Complies with ISO 10545-5

- Water Absorption: Tested by ISO 10545 - 3 ≤ 0.5%

- Deep abrasion resistance: Tested by ISO 10545 – 6: Max 175 mm3

- Frost…
