Q7) state who may write the specifications of a project? When a design company should hire an outside specification writer Q8) why “Knowledge of construction material and their market availability is important to be known by the specification writer Q9) when and where we should use TYPE II cement and why Q10) what is the problem of the following specifications statements; a- “SSPC-SP-6 paint or any equivalent paint” b- “ the contractor should submit foundation reinforcement details to the engineer and acceptance and approval should be submitted to him by the engineer at least 7 days before construction starting schedule of the foundation” c- “ Constructed columns dimensions should be not more or less than designed columns dimensions by more than 0.0001 inch” d- “proper site dewatering should be done by the contractor” Q11) State if these statements are true or not? Why? a- “Descriptive specifications” are related to “Quality Assurance” b- “Performance specifications” are related to “Quality Control” Q12) what headings should the bid table have? Q13) In quantities estimation which of the following rounding numbers is appropriate and which is inappropriate a- Round 7808 to 7800 b- Round 6111 to 7500 Q14) state two reasons for change in quantities estimated during the design phase from those quantities actually constructed Q15) Define “Unbalanced bid”, and state what the contractor may try to do when submitting an unbalanced bid

Q16) Analyze the bid table shown below and investigate if there is an unbalanced bid. Specify the items and find the difference table for all items for this bid compared to engineer. State which items are for cash flow, which may be under estimated and which are may be overestimated by the engineer from the unbalanced bid contractor point of view.
