ENGINEERING
Dear Readers
The contents of this publication has been prepared by Engineers of long experience in implementing Remodelings-Industrial Construction- Construction of Buildings
We appreciate any comments ,that help improve this blog
The importance of the Item Engineering in the formulation of a Estimation, is according to what we are estimating
- If we are selling Conceptual Engineering and /or Basic engineering, in addition to the Construction of the work , the relevance that acquires the engineering ,surpass the cost and the risks of the work, since we are selling a Concept or idea ( generally patented )..For example.. If we Construct a house, that esthetics and functionally, satisfy the Customer , or a procedure ( that make a transformation).. for example ... the Basic Engineering to separate the effluents from Petroleum Refinery in water and Oils , or the Basic Engineering to convert paraffin oil in Aviation Naphtha
The concept, the technique, the creation ..definitively..exceeded the cost of the action of Constructing
Anyway, when the Professional or the purveying Company of the Basic Engineering allows to, the Client, first acquires the design or the Basic Engineering ,that is suitable to their requests and that next Bids for the Engineering of details and work's Construction separately
In these cases, the value of the design or of the Basic Engineering, are established by who sells it
- As to the cost of the Engineering of details (diagrams, memories of calculation, technical specifications, payrolls etc., that they allow to make a correct Construction), has also a cost that it varies according to the Client and the type of Work
#According to the Client, because some are very demanding as to the level of detail, shape and periods for the presentation of the Engineering of detailed and conformed diagrams to Work
#According to the type of Work, because there are Works that present an important degree of interference with the existent Facilities, or Works with sophisticated control systems , or Works that require calculations that need to be accomplished by specialists, etc. -
When we are found in front of this type of situations, the Engineering of details, increases its gravitation in the preparation of the estimation and in general they should value for comparison with similar works
- In the Bids in what the Engineering of details, can rate it , like the necessary to Construct the work without the complications that we decrypt more up, is pondered in the 5 % of the cost of the work
- In other occasions the Client delivers part or the whole Engineering of details and the estimation, to be done according to that situation
- We go back to conclude that the best estimator is the one that already did a similar work
