A Review Of rebar detailing standards
How to Estimate Rebar Detailing Services
Most construction projects require rebar detailing. There are different ways that rebar detailing services are provided. One way is through a "cut and throw" method which involves sourcing out read from a landfill site, cutting it up, and then dumping it into the project. The other method that is commonly used is through pre-fabricated rebar kits which require the detailers to manually measure and cut the rebar before it arriving at the fabrication shop.
When looking at steel erectors or fabricators the key to identifying reputable contractors and companies comes down to one fundamental quality. This is: do they build what they say they will? Most companies will either build something to meet a quote or simply put forth an estimate based on what is laid out in the contract. But by paying close attention to a few key things like:
Quotes - When approaching different firms for rebar detailing services one of the biggest mistakes you can make is to send an estimate. The estimate is simply an offer and nothing more. The estimate should be used as a starting point to help structural engineers, rebar fabricators, and steel erectors develop a strategy for the job. By developing a strategy the client can get a better idea of how much the job will cost and then determine if they can afford it or if some changes or upgrades are needed.
Drawings - Rebar detailing services do not just mean a physical drawing. More than likely your client will be requesting rebar drawings and additional photos. These additional photos will prove useful when it comes time to build the actual structure. The drawings will also prove useful when trying to negotiate terms with your prospective contractor. The drawings are the key to getting a reasonable agreement.
Structural Engineering & Analysis - Another aspect of rebar detailing services is getting an accurate analysis of the job. This analysis is used to determine what material is needed as well as rebar detailing standards how much of that material must be produced. This will vary greatly depending on the size and complexity of the job. Some of the other components that will be discussed are structural engineering details, site investigations, soil conditions, water availability, utilities considerations, zoning & building restrictions, etc.
Foundation Details - Along with foundation details the client will most likely be requesting rebar shop drawings as well. Most rebar shops will use detailed illustrations and/or virtual reality programs to show how the foundation will look once the structure has been poured. The foundation details will then discuss how to construct the foundation based on rebar detailers' drawings. In many cases, rebar detailers can provide rebar installation drawings as well as footing, roof, and wall drawings. Once all these components have been generated rebar installers will create the actual rebar.
Steel Fabrication - When looking at rebar detailing service it is important to look for a company that has a wide range of expertise. This is to ensure that they have a variety of certified steel fabricators that can meet the client's construction needs. A good rebar manufacturer should have a wide range of trained personnel that have a proven track record and can meet the client's specifications. These service providers should also have a good understanding of OSHA and other safety standard established organizations.
These are just a few aspects of rebar detailing. All these components can be derived from the actual drawings generated by the manufacturing engineers during the fabrication process. There is only so much a client can do in terms of estimating materials and labor costs. They are more interested in getting the job done quickly and efficiently with minimal loss of material as possible. When all these components of the detailing job are put together, it can help to determine an accurate estimate of materials and labor costs.
