Hi!
As part of our requirement in our school, we have to present a detailed engineering design of
(a) Gasoline Station (minimum of 8 units)
(b) Petroleum Storage Facilities
Does anyone have this? Thanks guys! Replies will be highly appreciated.

Title Testing fresh concrete. Self-compacting concrete. Slump-flow test
Descriptors Concretes, Cement and concrete technology, Self-compacting, Flow, Flow measurement, Flow rates, Viscosity, Test equipment
Abstract To assess the flowability and the flow rate of self-compacting concrete in the absence of obstructions. Not suitable for aggregates when the maximum size exceeds 40 mm.

Standard Number BS EN 12350-10:2010
Title Testing fresh concrete. Self-compacting concrete. L box test
Descriptors Concretes, Cement and concrete technology, Self-compacting, Flow, Flow measurement, Flow rates, Bars (materials), Test equipment
Abstract To assess the passing ability ratio of self-compacting concrete, measuring the ability to flow through tight openings including spaces between reinforcing bars and other obstructions without segregation or blocking.

Does anyone have waterproofing detail around a plunged steel column and basement raft/slab interface? The Plunge column often use for top-down basement construction or supporting prop/strut which support retaining wall. Steel Construction Institute (SCI) has a publication titled 'Steel Intensive Basements Guide' may have some detail published. This can not be varified as I do not have the publication.
Seismic Design of Precast/Prestressed Concrete Structures
Year of Publication: 2007
Number of Pages: 487
Published by: Precast/Prestressed Concrete Institute
Authors: Ned M. Cleland and S.K. Ghosh
First Edition
This manual provides current information on precast design within the context of the code requirements for seismic design, ongoing research, and the authors’ opinions about appropriate practice.
It must be emphasized that this manual, although sponsored by PCI, does not represent a consensus recommended practice. It represents opinions of the authors concerning some ways in which precast design may be carried out to conform to code requirements and to perform acceptably under seismic effects.
The methods and procedures discussed and illustrated are not a substitute for the sound professional judgment of engineers familiar with both earthquake effects and precast concrete construction. This manual will provide the engineer with acceptable ways of applying the seismic design provisions of ACI 318-02, ASCE 7-02, and IBC 2003 to precast concrete structures.
Contents: Chapter 1 – Introduction

Nature of Earthquake Motion
Design Philosophy
Seismic Design by the 2003 IBC

This series EN 14488 ‘Testing sprayed concrete’ includes the following parts:
- Part 1: Sampling fresh and hardened concrete
- Part 2: Compressive strength of young sprayed concrete
- Part 3: Flexural strengths (first peak, ultimate and residual) of fibre reinforced beam specimens
- Part 4: Bond strength of cores by direct tension
- Part 5: Determination of energy absorption capacity of fibre reinforced slab specimens
- Part 6: Thickness of concrete on a substrate
- Part 7: Fibre content of fibre reinforced concrete
Part 2 specifies two methods from which an estimate of the in situ compressive strength of young hardened sprayed concrete can be made.

This part of European Standard specifies a method for the determination of the fibre content of sprayed concrete from either a fresh or hardened (i.e. before or after set) concrete sample. Only the method using a fresh sample is appropriate with polymer fibres, while both types are applicable with steel fibres.

This European Standard is applicable to sprayed concrete, to be used for repair and upgrading of structures, for new structures and for strengthening of ground.
This European Standard covers:
- classification related to consistence of wet mix;
- environmental exposure classes; young, hardened and fibre reinforced concrete;
- requirements for constituent materials, for concrete composition and for basic mix, for fresh and hardened concrete and all types of fibre reinforced sprayed concrete;
- specification for designed and prescribed mixes;
- conformity.
This European Standard is applicable to wet mix as well as dry mix sprayed concrete.
The substrates to which sprayed concrete can be applied include:
- ground (rock and soil);
- sprayed concrete;
- different types of formwork;
- structural components constituted of concrete, masonry and steel;
- drainage materials;
- insulating materials.
Additional or different requirements may be needed for applications not within this document, for instance-refractory uses.
