How to analyze rates for Civil Engineering Projects

In order to settle a rate for a specific item, the factors liable for influencing the rate of that item, should be analyzed cautiously. So, the method of finding out the rates of an item is called as analysis of rates or rate analysis and it is dependent on the following elements :-

1.Specifications of works and material concerning their quality, proportion and      constructional operation method.
2. Quantity of materials and their costs.
3. Cost of labours and their wages.
4. Location of site of work and the distances from source and conveyance charges.
5. Overhead and establishment charges
6. Profit

Cost of materials at source and at site of construction: The costs of materials are assumed as supplied at site all-encompassing the transport local taxes and other charges.

The objective of Analysis of rates:

1. To compute the per unit real cost of the items.
2. To calculate the reasonable exercise of materials and processes in accomplishing the specific items.
3. To calculate the cost of additional items which are not presented in the contract bond, but should be executed following the instructions of the department.
4. To modify the schedule of rates because of raising in the cost of material and labor or owing to alteration in technique.

standard schedule of rates: The labor charges is gathered from the standard schedule of rates 30% of the skilled labour submitted in the data may be considered as Ist class, left over 70% as II class. The rates of materials for Government works are predetermined by the superintendent Engineer for his circle annually and accepted by the Board of Chief Engineers. These rates are integrated in the standard schedule of rates.

Lead statement: The “Lead” is defined as the distance among the source of accessibility of material and construction site and it is presented in Km. The cost of conveyance of material relied on lead.

 This statement will provide the total cost of materials per unit item. It consists of first cost, conveyance loading, unloading stacking, charges etc.

 The rate demonstrated in the lead statement are intended for metalled road and contain loading and staking charges. The environment lead on the metalled roads are obtained by multiplying by a factor. 

a) For metal tracks – Lead x 1.0
b) For cartze tracks – Lead x 1.1
c) For Sandy tracks – Lead x 1.4

How to estimate the quantities of masonry works

In a Masonry work, the cement and delicate aggregates devoid of any coarse aggregates are applied for constructing a structure. There exist various types of masonry work:

1. Brick Masonry

2. Concrete block / brick masonry

3. Stone / rubble masonry

4. Clay tiles, etc.

Masonry works like brick masonry, concrete block, stone or rubble masonry are usually estimated with volume, but in some cases these are computed with regard to area where the thickness of masonry is confined to single brick or single block. Tiling is estimated in area.

To estimate the quantities of masonry work, the wastage of materials like bricks, cement or sand as well as the types and classes of bricks, blocks or tiles are not considered. All types of masonry works are calculated individually into categories to estimate the perfect cost of construction on the basis of its price.

To estimate masonry works, the guidelines given below should be maintained:-

1. Masonry is computed as “net in place” containing deductions for openings like doors, windows, ventilation etc.

2. Various shapes of masonry units are individually estimated which range from rectangular, circular etc.

3. Masonry at various heights is estimated individually as masonry at greater elevation from ground may need scaffolding and hoisting.

4. Masonry work is estimated independently in the following diverse: a. Facings, b. Backing to facings, c. Walls and partitions, d. Furring to walls, e. Fire protection

Ferrocement is a useful construction material to prevent structural damages due to earthquake

Ferrocement refers to a one type of thin wall reinforced concrete generally formed with hydraulic cement mortar reinforced together with tightly placed layers having continuous and comparatively small size wire mesh. Metallic or other suitable materials are used to develop the mesh.

Ferrocement contains a very high tensile strength-to- weight ratio and greater cracking behavior as compared to traditional reinforced concrete. Therefore, the thin ferrocement structures seem to be comparatively light and watertight. Extensive use of the ferrocement materials are found in developing prefabricated housing units, boats, barges as well as hulls for boats, shell roofs, and water tanks and other portable structures. Ferrocement is approved by ACI 549R-97 for the above mentioned structures. Ferrocement is considered as a superior material because of its tightly apportioned reinforcement.

Ferrocement provides great advantages to the construction professionals due to cost efficiency, accessibility of materials, quick time of fabrication and flexibility of extension and portability.

Construction Equipments and their various usages

The site managers and construction planners should have clear ideas on the features of the leading construction equipments which are extensively utilized in various construction projects. The on-site productivity mainly depends on the amount of time needed and effort which can be significantly affected by the improper selection of type and size of construction equipments.

 Excavation and Loading: One family of construction machines intended for excavation is generally categorized as a crane-shovel.

 The crane-shovel consists of three most important components:

• A carrier or mounting which offers mobility and stability for the machine.
• A revolving deck or turntable which includes the power and control units.
• An attachment located forepart that provides the special functions in an operation.

The crawler mounting is specifically useful for crawling over comparatively rugged surfaces at a construction site. Other types of mounting range from truck mounting and wheel mounting offering superior mobility amid job sites, but superior surfaces are needed for functioning efficiently. The revolving deck contains a cab to accommodate the person responsible for operating the mounting and/or the revolving deck. Here in figure 2, the types of front end attachments might contain a crane with hook, claim shell, dragline, backhoe, shovel and piledriver.

Typical Machines in the Crane-Shovel Family: Here a tractor contains a crawler mounting and a non-revolving cab. If an earth moving blade is connected to the forepart of a tractor, the assembly is termed as a bulldozer. If a bucket is connected to its forepart, the assembly is called as a loader or bucket loader. There exist various types of loaders which caterer to most competently deal with materials containing diverse weights and moisture contents.

Scrapers refer to multiple-units of tractor-truck and blade-bucket groups with different combinations to allow the loading and hauling of earthwork. Most important types of scrapers consist of single engine two-axle or three axle scrapers, twin-engine all-wheel-drive scrapers, elevating scrapers, and push-pull scrapers. Every type contains dissimilar characteristics of rolling resistance, maneuverability stability, and speed in operation.
