Sea Port Construction, Project Execution PlanDetails of how a Sea Port is constructed, and how the progress, safety and quality will be monitored and controlled. Also the measures to ensure that the site is environmentally friendly.

http://www.slideshare.net/DavidHMoloney/sea-port-construction-project-execution-plan

Brief Description

The purpose of this presentation is to give an understanding of the Methods, Plant and Sequence to construct a Sea Port .

This presentation can be used to engage Stakeholders and to get the Site Teams commitment to the programme. Also can be used for Induction Training and as a way to capture and share knowledge.

Project Execution Plan (PEP) details how a project will be executed, monitored and controlled.

High in Educational Value and easily understood. Recommended for Continuing Professional Development (CPD)This Video Presentation is innovative and has many beneficial uses.

Quay WallQ

Brief Description

The quay wall is constructed using precast reinforced concrete hollow blocks that weigh up to 160 tonnes. The blocks were cast in the on-site precast yard and loaded onto barges at the temporary loading jetty that had a 200 tonne capacity gantry crane.

A screeding frame that extended from the sea bet to above water was used to place the bedding layer to the correct level.Up to 22 blocks were placed per day using a barge with a crane.Part of the coping beam was cast in-sit-u in sections using concrete pumps positioned on the reclaimed land behind the quay wall.

The breakwater is constructed using core rock, rock armour, precast armour units and geotextile.The core rock is placed using split hopper barges in deep water and by lorry tipping and dozers in shallow water where the risk of slippage is minimal.The precast armour units are placed using crawler cranes fitted with a real-time visual aid system that enabled 70 placements per day.The wave wall is cast in-sit-u in 6 metre long sections.

Full-scale sample castings are constructed to demonstrate and document that all the requirements of the concrete and the execution of the work are fulfilled using the actual methods and performed by personnel that will carry out the future castings. One concrete component of each type is produced for approval. The approved castings were retained in a dedicated area for quality assurance purposes.

All works were inspected in accordance with the Inspection & Test Plan on an ongoing basis, in accordance with the site Project Quality Plan. The ITP set out in matrix form the sequence of inspection steps, the governing document (specification, standards), the standard to be achieved, the persons witnessing and the supporting documents to be produced.

Brief Description

The sequence to construct a reinforced concrete wall is as

follows:

Tie the reinforcement.

Erect stop-ends and the wall shutters.

Pour and vibrate the concrete mix.

Remove the shutters after the concrete has hardened.

Concrete MixG

s

A concrete mix contains 5 major

elements: cement, water, coarse

aggregates, fine aggregates (sand) and

air in different proportion. Additional

elements such as pozzolanic materials (fly

ash, silica fumes or slag) and chemical

admixtures can also be incorporated to

the mix to increase its properties.

Dredging & ReclamationD

tion Brief Description

Dredgers are marine vessels used to excavate and fill under water.

Types

1. Cutter Suction Dredgers are used to dredge hard soils by cutting

and breaking up the soil using a rotating head at the end of a pipe

which is lowered onto the sea bed. The fragmented material is

sucked and pumped either into a hopper barge or through a floating

pipeline. During operation the dredger is anchored by a spud that

allows the cutting head to swing in an arc.

2. Trailing Suction Hopper Dredgers are used to dredge soft and

loose soils, gravels and silts. There are two suction drag heads

which are lowered onto the sea bed. These move with the dredger

along the sea bed. The dredged material is sucked and pumped

either into the hopper or through a floating pipeline to a discharge

area.

Rock - Excavability

The excavability of rock depends mainly on the rock strength and the layer thickness. This diagram shows excavation methods for rock of various strengths and thicknesses, with a free face.

Vibro Compaction - Fill behind Quay

Ground Improvement using deep vibro-compaction.

Purpose is to provide protection against liquefaction during a seismic

event. Also to provide a specified minimum ground bearing capacity.

Vibro-compaction was use to compact the Dubai man made islands

that were constructed from dredged sand.

Equipment.

Vibroflot with extension tube, hydraulic power pack mounted on crane,

diesel engine driven water jetting pumps, compressors, crawler cranes

60 tonne capacity, water tank, de-watering pump
