Construction material testing
Purchasing new house comes with some questions about design and construction quality. There are a lot of innovations in construction business these days, but it’s not uncommon to find people complaining about quality of their newly acquired house.
Violation of building code is the reason for structural and safety malfunctions, which compromises quality of the project. That creates a potential danger for people who are going live. Normally most of the defects are easily visible, but Lay man wouldn’t be able to find structural problems and material issues
Here are few things which you can check by yourself.
Usually every construction contractor promises quality construction, but few of them provide the detailed documentation, it is important that you check bookings, purchases, annexes, schedule of amenities, specification related to windows, fittings, doors, and flooring. Correct documentation creates pressure for contractor to deliver what he promised.
When purchasing new home some unscheduled visits will help understand the quality of work and construction.
Understanding soil is important because whole structure is going to be standing on the ground. Stability depends on the soil. You will find difference in soil samples as much you visit different places. Differences such as particle size and sand characteristics for aeration and drainage. US Occupational Safety and Health Administration (OSHA) defines following soil classifications
- Stable Rock
- Type A – cohesive, plastic soils with unconfined compressive strength greater than 1.5 ton/sf
- Type B – cohesive soils with unconfined compressive strength between 0.5 and 1.5 ton/sf
- Type C – granular or cohesive soils with unconfined compressive strength less than 0.5 ton/sf
Structural design is the most important component of construction like wireframe in computer graphics. Structure should be checked to withstand earthquakes of specific magnitude. Usually five or six years old building can easily withstand earthquake around 4.0 and some remarkable building are designed to withstand earthquake of 9.0. Mostly depends on weight distribution on the ground and quality of steel. Ignoring this part will be much costly in terms of adjustments and reconstruction.
Structure’s load defines the strength of concrete required. Contractor monitors closely concrete mix, composition varies on different stages. It’s not possible for you to check concrete mix on every stage, so you can appoint a supervisor or ask for certificate from laboratory.
ALTERATIONS & FITINGS
Check for alternation made as they are promised such as quality of electrical wiring, bathroom fittings, and so on.
Spend some time on the site, small details are usually missed in a brief visit. Ask questions, it clarifies things on time and provide chance for rectification. Know about construction, you
