Technology Assisting the Estimator Estimating loads are becoming more demanding. Estimate more projects in Technology Assisting the Estimator Estimating loads are becoming more demanding. Estimate more projects in less time. Electronic documents help estimators fight back. Electronic documents may help estimators win more projects.

What Are Electronic Docs? Same thing as paper, just on a computer screen. Spec’s What Are Electronic Docs? Same thing as paper, just on a computer screen. Spec’s are typically PDF files. Drawings are often TIF, CALS or DWF files. They are not the computer automatically calculating all the quantities.

Creating Electronic Documents Generated directly from CAD or Word Processor Generated from the applications Creating Electronic Documents Generated directly from CAD or Word Processor Generated from the applications in the exact same way as paper documents. The files that are created are Read-Only. The PDF spec files can are searchable. Scan Documents Readability issues. Wasted resources. Scanned specifications are typically NOT searchable OCR helpful but not 100%

Typical Costs to Contractors The contractor pays a local reprographics company to print the Typical Costs to Contractors The contractor pays a local reprographics company to print the entire set of documents Contractors prints only the sheets they need. The contractor may elect to print smaller sheets to reduce costs. A free viewer is used to print the documents to scale in-house. The above options does not represent a cost savings to the project, rather a cost shift is what has occurred.

Alternative to Printing On Screen Takeoff Measurements are taken from the computer screen. Identifies Alternative to Printing On Screen Takeoff Measurements are taken from the computer screen. Identifies what has been taken off. An organizational structure can be used.

Additional Features The measurements are modifiable. Review of takeoff easily accomplished. Highlighting View multiple Additional Features The measurements are modifiable. Review of takeoff easily accomplished. Highlighting View multiple views at a time. Ability to efficiently perform repetitive takeoff. Ability to copy and paste or link into estimating software.

Electronic Document Benefits Contractors can review the doc’s to decide if they want to Electronic Document Benefits Contractors can review the doc’s to decide if they want to bid the project. Receive project documents quicker (Internet/Email). Addenda docs are readable vs. faxed docs. Better distribution to subcontractors. Subcontractors receive a full set of plans that they can keep.

Additional Benefits Greater accuracy than digitizers. Easier to identify where cost differences occur in Additional Benefits Greater accuracy than digitizers. Easier to identify where cost differences occur in design/build projects. Measurements are modifiable and stored. All the measurements can occur before calculating quantities. Easier archival of documents. Ability to overlay drawing changes.

Benefit to Estimators The Takeoff and plan checkout process is streamlined. Takeoff time is Benefit to Estimators The Takeoff and plan checkout process is streamlined. Takeoff time is reduced. Standardized colors can be used for takeoff. Takeoff review is visual. Plans are easily taken with you, as well as the takeoff tools. Takeoff can be “Linked” to Excel

Benefits for Clients Graphically designated quantities with the numerical quantities. Increased communication prior to Benefits for Clients Graphically designated quantities with the numerical quantities. Increased communication prior to construction. Better estimates from contractor.

Other Benefits of Using Electronic Documents Presentations to show staging and site considerations. Project Other Benefits of Using Electronic Documents Presentations to show staging and site considerations. Project Manager can verify estimate quantities. % complete calculations and provide support to the calculations. As-built drawings. For remodel work, photographs can be included with the drawings.

Screen Size Does Matter Minimum monitor size should be 17”. Recommended 19” or Larger. Screen Size Does Matter Minimum monitor size should be 17”. Recommended 19” or Larger. Screen resolution 1600 x 1200 or above. Dual monitors are great. Plan view on one screen; details, schedules, specifications, or estimating software on the other screen.

Elect. Doc’s in Education Greater accessibility to plans & specs Reduced cost to students Elect. Doc’s in Education Greater accessibility to plans & specs Reduced cost to students Introduce students to more types of projects Easier to show students the solutions. Require students to still use scales and digitizer.

Elect. Docs in Education Cont. Computer lab has 50 computers with dual screens. Faculty Elect. Docs in Education Cont. Computer lab has 50 computers with dual screens. Faculty have gone to dual monitors. Industry is switching as a result of summer hires and graduates.
