Conceptual Estimating

Owing to high number of design constraints and intricacy of construction a system known as conceptual cost estimation (also referred to as predesign cost estimation) has been developed to conceptually estimate the costs for construction industries.

 

The project team members develop the conceptual estimate during conceptual design stage (generally before the construction drawings and specifications are available) and create a preliminary baseline cost estimate range based on the activities, materials and other sources of expenditure for designing and constructing a specified facility.

 

A well developed conceptual estimate is based on the study of historical project cost factors and result in forecasting rapid estimates accurate cost for project feasibility studies, budgeting and financing the finished products, financial valuation of a number of alternative projects etc.

 

The system is very useful for construction industries, chemical industries, refinery industries, industrial plants, engineering firms and operating companies as there is a strong requirement to generate precise cost estimates for new plants, major equipment acquisitions or upgrades, large maintenance projects, new buildings, etc.

 

Conceptual estimating also provides great assistance to the structural engineering sectors as it looks at the performance specifications and footprint of a structure and creates a budget for all of the activities regarding steel in the structure including detailing, fabricating, painting, transporting and erecting.

 

There are various techniques available for conceptual cost estimation. Regression analysis, simulation, and neural networks are mostly recognized techniques that are used all through the initial project stages.

 

In regression analysis one can estimate the project cost with a regression model as well as a number of independent variables. Here, cost-conscious models were considered for both regression and neural network modeling. A cost conscious model seems to a model that fits the data adequately without using any unnecessary parameters.

 

In order to enhance the conceptual estimating process new and improved cost estimating software has arrived for more efficient computations as the process often involves complex mathematical calculations and requires advanced mathematical techniques. These software led estimators to have more time to visit and analyze projects.

Additive manufacturing alias 3d printing technology becomes popular in construction and engineering sectors

Arup, the most recognized multidisciplinary firm that offers innovative design services for structural engineering, has applied 3d printing technology for the first time to produce structural steel elements for accomplishing complicated projects. This system facilitates to minimize costs of the construction as well as waste.

This newest 3d printing is also recognized as additive manufacturing and it can be used for generating complicated individual- designed construction steelwork more professionally in quickest possible time.

3D printing technology can contribute to reduce costs, waste and the carbon footprint of the construction industries.

 

With 3D printing technology, the project team was able to redesign a steel node having a complicated geometry that could be applied in a lightweight structure, like a footbridge.

Arup has vast experience dealing with identical structures, along with the tensegrity – a balance connecting compressive and tensile members – structure of the Kurilpa Bridge, in Australia, where Arup’s role was to create engineering design of the pedestrian bridge. In this project the geometry of the bridge was straightforward, the cables (in tension) and tubes (in compression) were assembled with a structural rhythm that offers strength and resilience.

 

The additive manufacturing can help in making several complicated individually designed pieces more competently. This approach basically forms a very refined design devoid of simplifying the design afterward to curtail costs.

Labor Estimating

Good project management in construction depends upon the well-organized application of labor, material and equipment as these components comprises a large part of the construction cost. In order to control cost of constructed facilities, labor estimating is one of the most important concerns.

The owner can gauge the success of an operating system on the whole with labor productivity by utilizing labor, equipment and capital to transfer labor efforts into useful productivity.

The labor estimating will vary according job location, accessibility of skilled labor, contract wage regulations, union or open shop labor requirements, general market conditions, and so on.

Labor Productivity is frequently described as functional units per labor hour for each type of construction task. The thorough application of labor hours to a quantity result in managing the exactness and competence of an estimate. The assessment and explanation of the labor hours often leads to the accuracy of the project’s schedule and work force requirements.

The project costs include the major factors like combined costs for worker’s compensation, unemployment insurance and social security taxes. The perfect method for including these costs is to describe labor hours and wage rates; then apply percentages to the labor costs.

If construction output is stated in terms of functional units, the labor productivity will be related with units of product per labor hour, for example cubic yards of concrete placed per hour or miles of highway paved per hour.

On the contrary if it is expressed with constant dollars, the labor productivity is recognized with value of construction (in constant dollars) per labor hour to which factors for waste, overhead, and profit are added to capitulate the unit cost in dollars. A labor dollar per unit of work (ex: $20 per cubic yard for grade beams or $30 per cubic yard for walls) will only be relevant if the cost history supports the data being used.

Now-a-days computer aided design software are available for perfect labor estimating. These softwares are applied for collecting and controlling all labor records, analyzing labor costs with projects and activities for inclusion in project-based cost analysis and reporting. In order to get a perfect estimation of the complete construction costs, just add the labor estimating cost and other contingency expenses.

Plexxis Software launches the beta version of Electronic Price Agreement (EPA) for construction estimators

Plexxis Software introduces the Electronic Price Agreement (EPA) intended for the Drywall ERP estimating, digital takeoff, construction management software, and mobile app solution. It is still in beta stage. The estimator can apply it for getting the most updated material pricing for bids efficiently and precisely.

 The application comes up with some intuitive features like filtering, sorting, automatic quantity conversion and material code matching standard. Another exclusive feature is the EPA Unit Of Measure Intelligence (UOMi) that aids estimators to forward a request concerning material pricing in the units of measure they prefer. As for instance lineal feet or number of screws. The supplier will also able to provide pricing in their favorite units of measure like sheets or box of screws. The UOMi will provide huge benefits to both estimators and suppliers by converting as well as updating pricing easily and smoothly.

 

Plexxis is also planning to include some exclusive features like Bid Protection, Search & Suggest, Code Match etc.

Bid Protection will allow estimators to alter quantities a little or merge quantities from several bids with the intension of avoiding third parties from finding out projects that are being bid on.

 

Search & Suggest feature helps suppliers to go with the same database search features like estimators and acquire the rapid item searches and the calculation of special offers outside of the estimators requests.

 

With Code Match the estimators can automatically matches their material codes with the codes utilized by the supplier. As a result both can immediately analysis items as required by them.

 

EPA beta testing is planned for 4 months. After that all Plexxis customers can utilize it for their work. To avail the demonstration of the product, wall and ceiling contractors can make contact with Plexxis. For getting more updates about the product visit the Plexxis website.
