Here's a step-by-step of what is going on behind the scenes for the construction of the Fitzroy to Gladstone Pipeline (FGP) - and it's quite a process. 1️⃣ The Right of Way (ROW) is surveyed and investigated. Cultural Heritage Monitors conduct a ‘walk through’ to identify artifacts. 2️⃣ All vegetation is removed from the ROW. 3️⃣ The ROW is cleared of all obstructions and bulldozed to prepare a flat construction platform. Topsoil is reserved for reinstatement later. 4️⃣ A survey is conducted to determine the centreline and the centreline is pegged. 5️⃣ Pipes are ‘strung’ end-to-end along the ROW next to where the trench will be dug. 6️⃣ A trench is excavated using specialist heavy earthmoving machinery. Trenchless methods, such as drilling or boring, are used where the conditions do not suit the use of an open trench, such as waterways, rail, and some roads. 7️⃣ The pipe is laid into the trench using specialised heavy machinery. 8️⃣ The trench is backfilled using soil maintained from step 3. 9️⃣ Specialised equipment is then used to test the pipeline’s pressure – called hydrotesting to expose and rectify any operational defects. 🔟 All areas affected by construction are reinstated to pre-construction conditions as far as practicable.

The trial pit is dug to conduct subsurface investigations, providing an understanding of the soil's composition characteristics and geological conditions. This aids in assessing the site's suitability for construction, analyzing soil properties as construction material, and informing foundation design to ensure the stability and safety of the structure/facility. #geotechnicalengineering #testpits #groundinvestigation #tailings

(Excavation of pits for column ) There are several types of excavation methods used in construction, including trench excavation, basement excavation, cut and fill excavation, slope excavation, dredging, footing excavation, pit excavation, rock excavation, channel excavation, trenchless excavation, and underwater excavation.

Dynamic compaction also known as dynamic deep compaction is a method used to improve the ground by repeatedly dropping a heavy steel weight onto the surface. This technique has been applied worldwide to various construction projects like roads airports, and large halls. The goal is to transmit strong energy waves through the soil to enhance its properties at depth making it suitable for all types of granular soil. Dynamic compaction is especially useful for nonorganic fill made ground and areas with different characteristics, even when large blocks are present. It is effective in both dry and wet soils below the water table.

THE Exposed Pipeline Remediation Experts Little Mulberry Creek Case Study – In our latest case study, discover how Submar protected a 24-inch natural gas pipeline that was exposed for 10 feet due to headcutting at Little Mulberry Creek in Chilton County, Alabama. The site was dewatered using sandbag dams and pumps. Both banks and the streambed were graded, and a geotextile material was placed on top of the grade. A Submar articulating concrete mat system was installed from high bank to high bank to armor the pipeline. All edges of the mat system were toed into anchor and flank trenches that were backfilled with existing material and rip rap. A subgrade rock grade control was installed downstream of the mat system to prevent headcutting. Geotextile and rock were installed on the banks for bank paving. Submar offers comprehensive turnkey solutions for onshore and offshore pipeline protection, erosion control, and streambank stabilization for the pipeline industry. Our services include site inspection and surveying, environmentally conscious engineered designs, environmental permitting and regulatory compliance, product design and manufacturing, project management and construction, and post-construction monitoring.
