Terms and Conditions: Detail Engineering Assessment for Structural Safety 1. Deliverable: Report and As‐built Drawing in line with the codes and regulations.
2. Scope of Work: Limited to evaluation only not covers any retrofitting works.
A. Concrete & Reinforcement Configuration Tests :
I. In‐situ 4”/3” core cutting & testing from BUET lab by Universal testing machine (UTM) for determine
compressive strength of concrete. Core gives the actual compressive strength of particular concrete, but
it is advisable to collect minimum number of core from existing building. At least 4 Nos of core (per
building) may be sufficient. UPV and Rebound Hammer will be used on the same spot of coring and
determine compressive strength separately. The calibrated results of core test and UPV & Hammer shall
be used to determine a reliable value of concrete strength. Thus the compressive strength of concrete
for all key load caring structural members of the structure will be determined by UPV & Hammer.
II. Test of rebar for tensile strength.
III. Using the above mentioned correlation from core test and UPV with Hammer test regarding compressive
strength, UPV and hammer will be used at least 15 spot (/building) to determine the compressive
strength of key structural Elements.
IV. In‐Situ Scanning test – Using Ferro Scan (Existing Rebar detection) at least 15 nos. per building.
B. Soil Test:
Soil test at minimum four locations.
C. Foundation Explorations:
At least Three (If required more) Foundation (/Building) will be explored to verify its size with existing design drawings.
D. Structural Design for check existing structure:
I. Analysis of sub‐soil investigations report.
II. Develop computer simulated Finite element model (With Etabs/ Sap) by using concrete compressive
strength and rebar tensile test data.
III. Analysis will be performed as per Guideline of BNBC 2006.
IV. Checking of structural stability and safety.
V. Checking of lateral load resistance capacity of the Building
VI. Design check for soft story & Dynamic Load (For earthquake & Wind load)
VII. Checking of Special joint detail for earthquake or other lateral load.
