2.6 Design Method
- Ultimate Strength Design (USD) method will be adopted for design of all R.C.C. structural members.
2.7 Plinth level
- Plinth level will be finalized by RAJUK/Cantonment Board considering the record of rainwater logging on the nearby roads and it will also be higher than the highest previous flood level as recorded during 1988-2006.
2.8 Aesthetic & Functional Aspects

- Cross ventilation for natural air circulation and wide windows for allowing natural light shall be incorporated in the floor plan.
- Emphasis to be given to the privacy of master, first and second bed room in relation to the common users facilities.
2.9 Drawing, Design and Approval
- All architectural design and drawing will be approved by the architect in consolation with Land owner.
- Structural design and drawings will be done by the Qualified Structural Engineer.
- Clearances and approval required to execute the projects shall be obtained by the Developer in a proper manner and a copy of the papers so received in this regard shall be handed over to the land owner.
3. MAJOR STRUCTURAL MATERIALS
- High Strength Deformed Bars (60,000/40,000 psi) will be used in the structural design.
- The bars will be sourced from reputable manufactures such as BSRM/ KSRM/ Rahim steel mills Ltd, AKS STEEL.
- Grade-60 will be used in all RCC works except lintel, false slab and boundary walls while Grade-40 will be used in the RCC works in lintel, false slab and boundary walls.
- Random testing procedure will be maintained. Cylindrical Tests shall be done at BUET Laboratory. If required.
- High quality cement should be used as building material. Portland cement manufactured by Cemax/Scan/Emirates/ Premier /Crown cement could be acceptable.
- Recent testing result of cement will be collected form the company concerned and if required, testing may be done at BUET Laboratory. If required.
- Stone chips will be used in all casting in foundation, column and picket bricks chips in beams, roof slabs.
- Stone chips will be collected from crushing of boulders of Sylhet origin.
- Saline-free Coarse Sand (Sylhet Sand) of minimum F.M. 2.20 (will be used in RCC work after proper screening).
- Saline-fee Medium Sand of minimum F.M. 1.20 (will be used in RCC works after proper screening while both screening and washing shall be done for using in brick work and plaster).
Special Note: All structural materials including steel, cement, Bricks, Sylhet sand and other aggregates etc. will have to be of highest standard and quality as available in the market. In case of non-availability of shortage of supply of any specified item, an equivalent item competing quality will be used in consultation with the Land owner.
