We have been contracted by a number of pool installers this year to assist them in installing pools using “geofoam” as part of the design. There are some very good reasons why you would want to use this foam material in pool construction, as well as in other construction applications. With regard to pool construction, Geofoam is a great choice because it simplifies the construction process itself. It provides a medium onto which the concrete can be directly formed, rather than going through a more expensive process of forming and filling structures entirely of concrete.
When you choose a builder, landscaper or pool company, you also are choosing numerous other sub-contractors that will work in conjunction with the primary contractor you have chosen. This is especially true when heavy excavation or drilling is part of the project. Few contractors do this type of work themselves (in-house) because the equipment investment is very high, and the training needed get it done efficiently and safely make it prohibitive for contractor to do it themselves.
Landscapers Often Use Excavation and Drilling Specialists
In Northern California many houses sit packed together on small plots. With homes of 2,500 square feet or more sitting on a lot of 5,000 sq. ft. This can present some serious challenges if you’re thinking of installing a nice swimming pool, but it’s certainly not impossible. If you’ve been told a pool can’t be built in your yard there is a good chance the company you are talking with doesn’t want to bother. Or they don’t have people with the expertise to do it.
Tight Home Lots Make for Complex Excavation Work
The inclusion of reinforcement bars (‘rebar’) in concrete construction is a method that adds long-term strength to the concrete used to build foundations, walls, pools, pads and other structures. Concrete handles compression well, but without rebar would perform less well under tension or torsion (stretching and twisting). Load-bearing structures like foundations or walls need to handle multiple pressures from lateral and horizontal tension, compression and torsion. Rebar works well with concrete because these materials expand and contract at the same rate when temperatures change. Continue reading “How Rebar Reinforces Concrete in Construction”
Many public utilities have underground piping which is used to deliver services to all the residents and businesses of a given community. To avoid any injuries, damage to utilities, and or interruption of service, it is necessary to locate where these Utilities before beginning any excavation work. There are some hefty fines which can be levied against individuals or companies who damage utility lines.
How to Locate and Identify Underground Utilities
In the past, it was a common practice during the demolition of buildings or other structures to simply cart the waste materials away to a landfill. Today however, the growing cost of disposal and new materials, has put a greater emphasis on recycling old materials. De-constructing is an approach that involves a more careful disassembly of a structure so that parts of it can be reused or recycled. This has given a whole new face to waste management, one which reduces the amount of materials put into landfills, reduces the demand for precious natural resources and, best of all reduces the cost to the consumer.
The 4R’s of Construction Waste Management
An experienced builder understands that a sloped building lot presents issues such as stability, varying soil types, possible erosion, and poor drainage which can complicate construction and drive up costs.
The slope of the site might be obvious. If site drops six feet from one end to the other, for instance, you know you may need a deeper foundation on the low side, or a stepped-down foundation. Soil types are less obvious, but unstable soils can require remediation that also makes a site challenging to build on. And we have written previously about the utility of trenching to control water flow. Continue reading “Excavation: Grading a Sloped Construction Site”
Your property needs to properly drain water to protect your home. Foundations in particular need to be protected from pooling water and seepage. So the property surrounding your structure needs to be engineered to divert water from storms off the property easily.
And you may need to work with your neighbors. If their land stands at a higher elevation than yours, you may receive their water run off. One option in such cases is excavating your property: Digging trenches and installing French drains to divert the water flow away from buildings.
The Northern California rainy season has begun, and with it come special challenges for construction project crews.
The most common wet weather dangers are “slips, trips and falls.” These dangers are particularly prevalent when working in elevated positions such as when using scaffolding, hand holds, stairs and ladders. Even after the rain stops, conditions remain muddy underfoot for days.
Strong winds create their own hazardous conditions, scattering unsecured materials and putting pressure on scaffolding. Wet and windy weather can also make driving and operating excavation machinery more dangerous due to slick conditions and reduced visibility. Continue reading “Excavating and Drilling in Wet Weather”
Excavation and trenching are naturally hazardous construction operations, and contractors need to take all the appropriate steps to ensure worker safety. The Occupational Safety and Health Administration (OSHA) defines an excavation as “any man-made cut, cavity, trench, or depression in the earth’s surface formed by earth removal.” A trench, in particular, is defined as “a narrow underground excavation that is deeper than it is wide, and is no wider than 15 feet (4.5 meters).”
When we approach any excavation, drilling or demolition job we keep safety first, starting with the planning for the job. It is not just the possibility of the sides of an excavated plot or trench collapsing. Safety planning also must accommodate the interaction of our people and the machines they need to employ to carry out the job, and the terrain on which those machines must operate.
