Ans: One way slab is the slab having ratio of longer span to shorter span equal to or more than 1.5 . If the ratio of longer span to shorter span is equal to or less than 1.5, then such slabs are called as two way slab.

In one way slab main tensile reinforcement is placed parellel to shorter side which will be the main steel, where as in two way slab both direction required main steel.

Rock wool is a materialused for heat and sound insulation, which is made by blowing steam or air through molten rock. It is wool-like, but does not come from fleece.

ICI Construction stands for Industrial-Commercial-Institutional Construction.

Overseeing contractors and releasing payments.

The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.

Noncombustible materials are those that will not ignite, burn, support combustion, or release flammable vapors when heated. While these materials cannot be ignited and will not support combustion, they may react to heat in a manner that could affect structural stability. As an example, unprotected steel is a noncombustible material, but it expands significantly when heated, which could either push a wall out or, if it is confined, twist and turn, with the possibility of structural members falling. In addition, at about 1,000°F (538°C), steel loses about fifty percent of its load-carrying capability.

Subcontracting in the construction industry offers several advantages, including access to specialized skills and expertise that enhance project quality and efficiency. It allows primary contractors to manage workload more effectively, as subcontractors can handle specific tasks, leading to faster project completion. Additionally, subcontracting can provide cost savings by reducing overhead and labor costs, enabling companies to focus on their core competencies while still meeting diverse project demands.

An infrared home inspection is the modern way of inspecting a home. Fading fast are the legacy style of typical home inspections. The days of peek and poke, inspecting with a flashlight and a clipboard are going out of style with VHS recorders. The brightest flashlights can not look through sheetrock, drywall, and flooring. Very similar to going to a dentist who does not have x-ray equipment. Modern high resolution infrared cameras can look through building materials like sheetrock, paneling, plaster, drywall, wood and tile flooring and roof materials. Infrared home inspectors can now discover and report on things like mold, termites, sewer and drain leaks, plumbing leaks, leaking roofs, missing insulation and overheated electrical circuits. Infrared home inspectors can inspect the entire home. Legacy non-infrared inspectors can only inspect the portion of the home that is visual. Depending on your location, infrared home inspections cost about $100-150 more than conventional home inspections. All super inspectors have infrared equipment.

A safety officer can be someone like a police officer who is engaged in law enforcement.

A safety officer can also be the person in a workplace who is responsible for assuring that the work is done in compliance with the workplace health and safety standards and regulations. Establishing such a position is usually part of an immature company safety culture and often results in the "safety officer" becoming an enforcement agent (and the employees complying only when he is present.) A workplace safety program works better i the long run when a Safety Specialist, rather than a Safety officer, is in place and can operate as a guide and adviser to management and labor.

A safety officer is a person in an organization to set a vision, to establish a plan, to implement the planed procedures and to follow-up and audit, in order to ensure a safer workplace. therefore his scope extends much beyond a "Police officer's duty". He acts as a policy maker, supplies officer, trainer, police officer and a Savior to minimize accidents to save people, properties, cost and the environment. Safety officer therefore is a highly productive position in any establishment.

both are derived from latin word arcus means bow

arch is a structure in the shape of arc

arc is the imaginary shape you can draw

Horizontal construction is the groundwork (grading, compaction, infrastructure, roadways, etc.) and vertical construction is from the foundation up of the actual structure (homes, apartments, etc.).

Road construction companies do the actual paving work on roads.

Prime cost is as follows:
1 - Cement (Raw material)(direct material)
2 - workers (direct labor)

it looks like a black square

Roughly 10 cubic yards (or 270 cubic feet).

It's a contra-asset account to construction in process. It's used to record periodic billings on a construction project.

One-way-solid slab flexible but limited in span. one way concrete joist system allows longer spans. Wide module or skip system allows longer span and uses less concrete than the one-way joist system. Slab bands or joist bands may be used with these systems, They serve to reduce the spans of the slabs to conserve headroom in the building.
 Two- way-2 way solid slab rarely used but useful where loads are heavy. Two-way flat slab good for heavy loading, two-way flat plate good for lighter floor loading. Very flexible in column locations. Conserves headroom in buildings. Two-way concrete joists or waffle systems good for long spans.

An elliptical construction is a construction that lacks an element that is recoverable or inferable from the context.

To calculate revenue per ton mile, divide revenue (R) by the product of the weight in tons (T) and the distance in miles (M) traveled.

Revenue per ton mile = R/(T x M)

A variation in a construction contract is a change from what is currently contracted to be built, supplied or fitted to a different build, supply or fit.

Variations are written instructions from the client to a contractor or from a main contractor to a sub contractor. The instruction will set out the details of the change so that all parties are agreed on the new construction details.

Typically, a variation is used to clarify a detail that could not be fully defined at the start of the contract - Paints, wall coverings, carpets are examples of such details that are often left to the end of the contract to decide. They can be used when unexpected issues arise during the contract. They are often used simply because the client changes his mind during a contract.

The final contract is often modified by hundreds or even thousands of variations that each reflect a change in the way the building contract is to run.

Its the preparation of a site ready for the first stage of development (e.g. Perimeter fencing, access routes, safety signage etc.) It may also include some preliminary construction works (e.g. groundworks). The result is a site that is ready and equiped for the main body of works to begin.
