Project Estimation Techniques

Industry Techniques

Estimating methods & Techniques

Estimating the surface area of a room or the number of marbles in a jar is relatively easy and can be done quite accurately with simple rules of thumb. However, estimating the total costs of an offshore LNG platform or a high speed railroad is a little more complex.

Luckily, there are numerous methods and techniques that can help you estimate those costs throughout the different phases of such projects.

Factor Estimating

In the first phases, you can make use of several factor estimating techniques that allow for an estimate with limited accuracy but enough confidence for a go / no go decision. The factor estimating method derives its name from applying derivative factors for the preparation of the investment estimate of a project. The method is sometimes called a top-down estimate and is based on limited project scope. It uses rules of thumb, parametric models or historical databases to provide relevant cost data. It can be used to develop for example cost per square foot for a building or cost for a similar piece of equipment.

Factor estimating is used because of several reasons, amongst which:

  • The scope of the project is not yet complete
  • Preparing a detailed estimate is time-consuming and therefore more expensive
  • Many plans won’t go through, so investing time in estimating a project that might be abandoned later on, can be considered a waste


Advantages and disadvantages factor estimating


  • Quick result
  • Inexpensive


  • Inaccurate
  • Black box idea
  • Limited possibilities for adjustments
  • Possibility for wrongly use
  • Estimating with only historical data
  • Labor intensive to develop benchmarks with a similar basis


Parametric estimating

Parametric estimating entails the analysis of cost, programmatic and technical data to identify cost drivers and develop cost models. The approach essentially correlates cost and manpower information with parameters describing the item to be costed. This process results in sets of formulae known as “Cost Estimation Relationships” (CERS), which are applied to produce cost outputs for different elements of an estimate. Parametric Method generally involves the use of a regression analysis (linear and nonlinear) to determine the best algorithms for a model.


Equipment factored estimating

An equipment factored estimate is produced by taking the cost of individual types of process equipment, and multiplying it by an "installation factor" to arrive at the total costs. In practice, this has proven to be quite a useful method since a substantial part of total project costs are made up of equipment. As a result, it’s the basis for many factor estimating methods.

The installation factor, or total installed cost (TIC) factor, includes subcontracted costs, associated direct labor costs and materials needed for installation of equipment.

Lang Method Illustration

Lang method

A method that is slightly more detailed and therefore needs some more project information, is the so-called Lang method. Its basis is the equipment prices free at site, of which it’s best to have quotations. The method differentiates for solids, liquids and mixed solids/liquids.

In short, the picture below explains how the method works.

Hand method

This method, developed by W.E. Hand, is an extension of the Lang method and proposes to use different factors for each type of equipment (columns, vessels, heat exchangers and other units) rather than per process type. Hand’s factors exclude indirect field costs (IFC), home office costs (HOC), and the costs for OSBL facilities, all of which must be estimated separately.

Detailed estimating

Sometimes called bottom-up estimating. With this method, detailed estimates are made at relatively low levels in the work breakdown structure (WBS), typically at work-package or task level. This approach is closely related to scheduling, planning and resource allocation and is both time-consuming and costly. It requires a good knowledge of the activity and there also needs to be a reasonable level of definition for the exercise to be meaningful.

Page & Nations

Not really an estimating technique but rather a method strictly used for estimating direct labor in man-hours. The direct man-hours of Page & Nations were determined by gathering hundreds of time and method studies coupled with actual cost of various operations, both in the shop and field on many piping jobs located on projects in the US. Ranging in cost from $ 50,000 to $ 20,000,000.

By carefully analyzing these many reports, an average productivity rate of 70% is established. The man-hours or percentages compiled throughout this manual are based on this percentage.

Cost Engineering

There are many other methods that you might use to develop estimates, but it’s those mentioned above of which its use is most wide-spread. Cost Engineering has experts for all of these methods, and can apply them within your organization for a wide range of projects.

Long term project in Central & Eastern Europe

Cost Engineering did a long term project with a group of Central and Eastern European companies who were in the process of revising a large part of their production facilities throughout Europe. For this combination of companies, Cost Engineering has audited all feed estimates and their related processes. This was not just a case of looking at the results on paper. It meant going out into the field to get a feel for the situation and applying that knowledge on information received from both owners as well as engineering contractors.

During this project, Cost Engineering audited over a billion Euro’s worth of projects both from an estimating as well as a planning point of view. As a final result the group of companies has a much clearer view of the cost involved in the project, resulting in reduced cost where possible.


Acting as independent third party

Cost Engineering has assisted an engineering firm in the process of calculating the cost of a number of projects they are conducting for their clients. By using Cost Engineering as an independent third party, there have been no discussions about the estimates and negotiations can be focused on the technical aspects of the projects.


Statoil's greenfield projects

For Statoil, we delivered several services, amongst which we estimated the costs of multiple Greenfield projects as well as integrated with existing plant projects for different locations in Europe.

Those different types of cost estimates followed their project phases: accuracy from 40% to 20%. With a probability of P80. Cost Engineering used its own database and reported on the NORSOK coding structure. Part of this was the evaluation of different scenarios before the transition to the following phase.

Offshore Oil & Gas

A broad range of cost risks

Cost Engineering is experienced in working for the offshore industry. As an industry which faces a very broad range of cost risks, the offshore industry benefits greatly from a thorough approach to its cost engineering.

Request information

High Estimate Accuracy

High estimate accuracy

In the offshore industry, the location has a major impact on the total project costs. For that reason, Cost Engineering establishes the project’s standard conditions (e.g. location, productivity, rates, etc.) and applies custom factors where needed to not only ensure high estimate accuracy, but also the ability to trace back sources of costs.

Risk assessment

Risk assessment

Cost Engineering realizes that offshore oil & gas projects often face significant investment risks. Therefore, a Capex uncertainty analysis will be executed for the appropriate phases. This analysis will be executed with a Risk Software Program @Risk based on the Monte Carlo simulation to determine the contingency to derive the cost estimate confidence level. This risk assessment will be based on the identified project risks.

Well-head and production platform

One of the projects Cost Engineering has worked on was a conceptual design and layout for a well-head and production platform which was defined from a zero base level. It was meant for a field approximately 12 km off shore which contains 36 API degree oil and associated gas. The export route is through an existing offshore complex located to the north-west of the platform. Because of the requirements for downhole ESPs, dry trees have been selected for all production wells in this field to facilitate access and work over. The water depth at the field is 20 meters (LAT).

The designs in this project are for one well-head and one bridge linked production platform. Due to drilling constraints the well-head platform is required in 2010 and the production platform is to achieve first oil in 2011.

For this project Cost Engineering was asked to:

  • Establish a weight estimate based on the preliminary info available at the end of the FEED phase.
  • Establish two cost estimates. One with an accuracy of ±30% and a second one with accuracy of ±15% both including construction and installation.
  • Develop the cost estimate for the platforms up to a certain level of reliability in order to make a validated assessment of the total investment cost.

Cost Estimate Data

Cost Estimate Data

Other estimating projects we delivered to offshore clients include the development of cost estimate data (FPSO, Pipeline, Subsurface) for Inpex and long-term offshore cost estimating support for NAM/Shell.

Certified Specialists

Certified Specialists

A number of clients use Cost Engineering to monitor and index their contract rates on a yearly basis. Others ask Cost Engineering to supply knowledge to their organization. In the recent past that has meant that we supplied three cost control specialists to an international organization.

In another example Cost Engineering provided a certified cost engineer to the daily maintenance organization for a refinery. During our presence new contracts were initiated, work processes streamlined and cost were reduced by introducing new ways for working with cost engineering tools.
