Introduction and Objective The purpose of this report is to provide the structural analysis and design for foundations for Main PEB Building in this project. Foundation design based on reactions provided in the figure 1 as shown below.
1. Along Grid A and along Grid G Main Frame PEB columns reactions provided and designed as concentric isolated foundation. This part is elaborated under the Chapter 6.
2. Along Grid G from Grid 1 to 4 Main Frame PEB columns reactions provided and designed as eccentric isolated foundation. This part is elaborated under the Chapter 7.
3. Along Grid A / 1 & 10 and along Grid G / 1 & 10 End Frame PEB columns reactions provided and designed as isolated foundation. This part is elaborated under the Chapter 8.
4. Along Grid 1 and along Grid 10 End wall PEB columns reactions provided and designed as isolated foundation. This part is elaborated under the Chapter 9.

Design Data & Materials Properties CONCRETE
Design of concrete shall be in accordance with BS8110:1998 Structural Use of Concrete. –
Reinforced structural concrete C40 Compressive Strength: f cu = 40N/mm2 with minimum 370kg/m3 Ordinary Portland Cement (OPC). Blinding Concrete C15 Compressive Strength: f cu = 15N/mm2 with minimum 280kg/m3 Sulphate Resisting Cement (SRC).
REINFORCEMENT STEEL
Two types of reinforcing steel will be used. •
Main Reinforcement Uncoated high yield strength deformed bars with characteristic strength of 500N/mm2 conforming to BS4449.
•
Links and Blinding Steel Uncoated mild steel plain bars with characteristic strength of 250N/mm2 conforming to BS4449.
4.
Stability Analysis In stability analysis calculations, using factored working loads, foundations shall be designed to have minimum factors of safety as noted below. The weight of soil overburden may generally be taken into account when calculating factor of safety, except as noted below.
Min factor of safety against overturning = 1.5 Min factor of safety against sliding = 1.5 Min factor of safety against uplift = 1.5 (including overburden) Min factor of safety against uplift = 1.1 (no allowance for overburden)
5.
Existing Ground As Per Soil Report The assumed parameters as per the geotechnical investigation report provided, are as the following:
