Company Profile

Three    Keys    Software    (the    holding    company    of    QS    Project Services)   was   set   up   in   1992   with   a   view   to   creating   a   more   cost efective   and   efficient   means   of   producing   consistantly   accurate estimates for use in the Construction Industry. Over   a   three   year   period   some   10,000   detailed   rate   buildups were   produced   covering   all   the   structural   and   finishing   trades   for use   with   the   Dos   Version   of   Buildsoft.   With   the   later   introduction of   Microsoft   Windows   these   rates   had   to   be   re-   written   for   the newly   updated   Buildsoft   Software.   During   this   process   another 2,000   rates   were   added.   and   finally      in   1998   the   Pricebook   was realseased onto the market.   In the beginning  It was after many years employed as a Chief Estimator/Estimating Manager with various major ‘Australian Construction Companies’, spending thousands of countless hours building up rate after rate that I decided that there had to be a more cost effective and efficent way of pricing projects whilst still being able to compete in the market place. Using my knowledge gained over many years in estimating using the ‘Buildsoft Estimating Software’,I slowly becan to computerise my rates into a workable model which all estimators could use. Because rates are built up in detail and allow the estimator to change  production levels, waste factors and profit margins, these rates would not be limited to any one country but could be used worldwide.  It was no mean task, taking around six years from start to finish, I had to make sure rates were consistant and easy to find. The first recalc of the database took around 24 hours to recalc once resources had been updated. These days using an I7 3.95 GHz computer with 32 GB or ram, It takes around 7to 8 minutes.
