Construct IT for Business, in conjunction with IT Construction Best Practice (ITCBP), have published "Computer-Aided Estimating," the latest in the series of How To Guides, specially written for companies in the construction industry.
A computer-aided estimating (CAE) system enables faster, more accurate estimates. It can lead to lower project costs and improved information flow. It is more flexible than the traditional manual approach, allowing any number of variables and "what if" scenarios. Yet while there is much to be gained from investing in a CAE system, construction professionals must approach the software selection and implementation process with care and caution. Computer-Aided Estimating provides essential practical advice and support.
"All too often companies select a CAE system and have no real understanding of the total purchase, implementation and maintenance costs involved or whether the system will really meet their business needs," warned Dr John Connaughton of Davis Langdon Consultancy, Project Manager for ITCBP. "It is essential that any investment in IT is approached with a realistic budget, a sound business case and clear, measurable goals and objectives."
"Computer-Aided Estimating" is an accessible, step-by-step guide to choosing and using a CAE system. As the guide demonstrates, a clear understanding of business needs and cost and training issues are just as important as the tools and technologies involved. Hints, tips and guidelines for successful software selection and implementation include:
1) Assess your business needs: It is critical that you identify your company's requirements and aims as a first step towards choosing a system. Establish the scope and complexity of the estimating system that will meet your needs and objectives. Compile a list of the capabilities you require and rate each as essential, beneficial or luxury. Ensure all systems you shortlist have 100% of the essential functions and at least 70% of the beneficial ones.
2) Test before you buy: Once you have reviewed the products on offer, established your requirements and drawn up a shortlist carry out "hands-on" testing using a recently completed tender and an experienced estimator. This process will give you a better feel for the software, its usability and its suitability for your needs. Take up references from a company that uses the system, preferably a company that's a similar size and operates in your area of business.
3) Address the training issues: Allocate time and resources to train and encourage users to become proficient. Don't cut corners in an area that is critical to the success of the system. Training should only be carried out by experienced users who have also been trained to train.
4) Determine the true cost of the system: The cost of the system itself is only a part of the total investment. Make sure you also take into account costs relating to maintenance contracts, implementation, support and management, training, upgrades, back up, and anti-virus protection and security.
