Roles and Responsibilities of a Surveyor in ConstructionDecember 11, 2017
Everyone's heard of a surveyor, but does that mean everyone knows the role of this skilled individual? On asking someone, an acutely self-conscious observer gestures vaguely while mumbling something about land development. He's almost right. In construction projects, surveyors examine land.
Benefits of Underground Electricity Connections versus Overhead Powerline ConnectionsDecember 4, 2017
Viewed from a strictly aesthetic point of view, underground electricity connections are obviously popular because they free land from overhead powerline connections. Strung in great loops, ugly overhead lines obstruct views. They also go down during a storm. Okay, so buried cables do require a greater initial investment, but great savings come to those who are prepared to make that investment.
Kiosk Substation Foundation Works: What is it all about?November 17, 2017
It feels a little counterintuitive, this notion that a building can be designed with open foundations. Heavy structures employ steel grids and strong concrete mixes, with the dried base forming a solid pad, right? That's almost true.
Locating Underground Cable FaultsNovember 2, 2017
High-voltage cables run across pylons and overhead structures, passing over highways and the outskirts of cities. When one comes down, it's a quick call to the electrical authority, and the power is back on before the day is over. Underground faults present an obvious extra layer of difficulty. The cable is under several feet of soil, maybe passing under a road or through the fringes of a park. It's neither logistically desirable nor cost-effective to call in the diggers and pull up the ground at random.
Safe Civil Engineering Work for Gas Pipeline and InfrastructureOctober 23, 2017
Gas mains systems deliver methane-based fuels to homes and businesses. The gas pipelines use cast iron or steel backbones. Further down the line, the piped networks branch into those residential and commercial properties as polyethylene or polyvinylchloride offshoots. Elsewhere, the pipeline infrastructure swaps natural gas for liquid petroleum or some other fossil fuel. This is civil engineering territory, the piped fluids that act as the lifeblood of a thriving community.
Backfilling of Sewer Sanitary Trench - Considerations and Compaction DegreeOctober 16, 2017
The effluent pipes are in place, the bedding material is packed, and the line has been tested for leaks. The backfilling stage comes next. Take a moment to consider the procedure. Remember, if this job isn't done right, the pipe could break. Sewage leaks stink. Worse still, they're a health hazard. Backfill that sewage sanitary trench with caution, with step-by-step professional care.
The Value of the Open Cut Trenching MethodSeptember 29, 2017
Have you ever taken a walk out onto a construction site only to be overwhelmed by what you see? Excavation sites can look like microcosms of little cities and towns with people hustling back and forth to do tasks you aren't familiar with. Stealing the show, as always, is the massive array of power tools and construction vehicles. These vehicles are extremely important particularly when it comes to the task of trenching.
The Importance of Geotechnical Testing in Trenching and Boring SafetySeptember 15, 2017
It's easy to write off excavation work as a simple job that requires little more than heavy machinery and the ability to dig. As it turns out, there are many different ways that an excavation can go wrong. A poorly done excavation, whether by way of horizontal boring or a fully exposed trenching, can lead to damage to property as well as potential injury to the workers at the site.
Excavation Risks and Dangers: Why OH & S is A Must?August 30, 2017
The OH&S exists to ensure workplace safety. The abbreviation stands for Occupational Health and Safety, for a regulatory body that traditionally looks after factory workers and construction personnel. However, on further examination, workplace settings are not set-in-stone. Excavation risks, for example, refer to an equally dangerous place of work. Imagine the scenario, the heavy equipment and the hazards in the trench.
Quality Control Checklist for Excavation WorkAugust 18, 2017
Adherence to the upcoming quality control checklist will ensure site excavation work is carried out methodically, from the arrival of the first excavator to the laying down of the final back filled load of topsoil. Absolute procedural control is the goal here, and that goal becomes that much easier to realize when a poorly coordinated process adopts a controlled, properly managed approach to this potentially hazardous operation. Let's begin with excavation planning.
What is Test Pit Excavation for Soil Evaluation and what is Its Purpose?July 27, 2017
Before a ground-based work project begins, a test pit excavation examines the properties of that ground. It uses a soil evaluation methodology to examine the soil conditions, to see if there's an easy to excavate ground covering, which would be the best case scenario. If the soil is loaded with clay and rocks, then the test pit provides important predictive data. Essentially, this is the trenching equivalent of a feasibility study.
Installation of Electrical Conduit SystemsJuly 19, 2017
If an electrical contractor has done his job right, the installation of an electrical conduit system fades into the background. A recent pass by a painting contractor also helps the tubular frame disappear into the supporting walls and ceilings. But what are these tubes all about? You probably picture the rounded channels carrying a mass of cables, and you're not far wrong. As with any technical service, though, there's more to an electrical conduit system than meets the eye.
Pipelaying Procedures for a Successful Water Supply SystemJune 30, 2017
Water supply systems are taken for granted in developed nations. If you twist a tap, there it is, pouring into your sink as clean water. Outside your home, the channels that convey that life-sustaining liquid are buried in trenches. Let's check out the pipe laying procedures that must be mastered before your clean water supply can be safely installed underground.
Trenching and Excavation Safe Work PracticesJune 16, 2017
Unenlightened observers can picture a trench as it is excavated. The imaginative individual similarly envisions mine shafts cutting through hard underground rocks and tonnes of soft soil. However, those considered musings tend to miss prosaic engineering features. In plain speak, real trenches and excavation projects require safe work practices as a figurative support mechanism.
Directional Drilling Definition and UsesMay 29, 2017
Directional drilling is defined in an engineer's handbook as a steerable boring technique. In other words, the technology mashes a standard vertically mounted drill with a horizontal directional drilling (HDD) system. Several engineering solutions paved the way for this guidable boring system, with oil drilling methods providing the best and most workable methods.
Water Tappings: What is it all about?May 16, 2017
It seems like a fundamental, even simplistic question, right? What are water tappings? Curiously enough, there's more to this work than meets the eye, but that's often the case. Anyway, water tappings are defined as utility connections that don't interrupt an existing service. Try and picture that, if you can, the plumbing of an additional water connection, one that doesn't force the main line to shut down.
High Voltage Installation Requirements According to Safety ObligationsApril 28, 2017
Electricity behaves differently when it passes into the higher power ranges. There are special switchgear buildings that manage the dangerously high voltages. Occupied by lines of spring-loaded switches and oil-filled circuit breakers, this is a surprisingly large setup, one that employs a lot of equipment. Let's take a gander at the high voltage installation requirements that come into play when these power distribution sites need work done.
Excavation, Bedding and Backfilling WorkApril 19, 2017
Laborious efforts uncover straight-edged trenches. This is a job for excavation equipment, the machinery that carves channels out of any soil type. Essentially, this work requires a great deal of engineering aptitude, plus many excavation tools. Importantly, what's being described here is a finitely managed cycle, a process that involves excavation, bedding, and backfilling work. Here's a closer look at this challenging excavation work.
Earthing and Electrical Grounding Installation: What is it all about?March 29, 2017
Recently, there were words said about Earthing and Ground Insulation. This was an opportunity to look into earthing theory so we could all understand the need for electrical grounding. Such concepts obviously require coverage, but we're really all about the practical work here at Metro Pits. This is a nuts-and-bolts issue, so why don't we move on to electrical grounding installation? It all begins with an earthing electrode.
Safety Management System and Risk Assessment in Infrastructure ProjectsMarch 22, 2017
An area-wide legacy is guaranteed when a new infrastructure project commences. There are new roads coming, new railway tracks and zoned parcels of land. Accompanying the engineering plans, a properly structured safety management system is required. It covers every hazard, every safety-oriented aspect of the construction work.
Roadworks and Cable Detailing: What is it all about?February 22, 2017
Roadwork projects look dirty and disorganised. Wash away that dirt, though, and there's order below the grime. That's because industrious roadwork ventures are arranged in layers. There's the labour up top, the methodical addition of traffic signals, utility lines, and numerous infrastructure extensions.
Hydraulic Engineering: Water Tapping and How Does it Work?February 15, 2017
Water main pipes pack municipal district lines with hundreds of kilopascals of pressurized fluid. The strong flow enters multi-storey buildings and housing clusters with a punch, an almighty torrent that pours from shower heads and domestic taps.
Road Construction Site Management and The Importance of Following Environmental GuidelinesJanuary 31, 2017
When a road construction site management safety helmet goes on, a very different skill set assumes command of a project. First of all, a fully qualified team is required to address a mind-numbing series of planning stages. Roadway guidelines and environmental impact studies, engineering procedures and communications skills, all of these tasks require management.
The Importance of Environmental Protection, Audit and Inspection in Civil Engineering ProjectsJanuary 25, 2017
There's a burden of responsibility attached to civil engineering projects, a set of ethically engendered obligations that regards environmental protection as an inviolable duty. Certainly, the on-site management team is charged with a great undertaking, work that will shape the land.
