TOPIC – SURVEY AND REPORT ON BUILDING IN DISTRESS
Presented by: Gauri Patil Under guidance: Prof. Rahul Chutake
ABOUT BUILDING IN DISTRESS……….
Distress
sadden, grief
- Trouble, pain, hardship,
FACTORS LEADING TO DISTRESSED BUILDING •Faulty design •Faulty construction material and workmanship •Faulty use , miss use or loading •Lack of maintenance •Age of construction •Sub grade changes •Atmospheric – thermal, light, moisture, radiation, wind chemical •Below ground – seismic activity, moisture, vibrations from neighbor, chemicals •Incidental – fire, flash floods, cyclone etc.
•
WHY BUILDING SURVEY AND STATUS REPORT?
To maintain building in good condition to increase its life. Exact details of distress at columns/beams/slabs (cover or
core) 25%-50%-75% shown in colors. Useful for loan application to bank, useful for insurance claim.
Members can understand the exact status/condition of their property Helps contractors to understand the exact nature and sources of distress
before touching the structure for repairs, so chances of increasing the work/cost is minimal. Even owner can visualize the extent of repairs during work It has remedial measures Estimated repair cost and priorities can be decided On the strength of authentic reports even after some years if problem arises one can contact consultants or contractor for rectifications Consultants involvement in repairs (proper planning-systematic/methodical repairs) improves the work
INTRODUCTION………BUILDING SURVEY
BUILDING DIAGNOSTICS/SURVEY IS A HOLISTIC PROCESS OF DATA
COLLECTION REGARDING CONDITIONS, DETECTION AND ANALYSIS OF FAULTS/ABNORMALITY/DEFECTS IN BUILDING MATERIALS AND FABRICS.

BEFORE BUILDING SURVEY…..
Obtain building permit for survey Set of architectural and structural drawings Data collection Name of project Location Age Year of construction etc. Form a group and work allocation
CHECK LIST BEFORE SURVEY 1.Measuring tape 2.Camera 3.Pen, pencil, etc. 4.Notebook and questionnaire
5.
MINIMUM REQUIREMENTS FOR ASSESSMENT OF DEFECTS & THEIR CAUSES
•PRESENT CONDITION •ORIGINAL DESIGN APPROACH •ENVIRONMENT AND CONTAMINATION •CONDITIONS DURING CONSTRUCTION •HISTORY OF STRUCTURE •FUTURE USE •INTENDED USE, DESIGN LIFE & SERVICE LIFE •REQUIRED PERFORMANCE CHARACTERISTICS •LONG TERM PERFORMANCE OF PROTECTION OR REPAIR WORKS. •ADDITIONAL PROTECTION & MONITORING •NUMBER & COST OF SUBSEQUENT REPAIR CYCLES •COST & FUNDING OF ALTERNATIVE PROTECTION OR REPAIR OPTIONS, INCLUDING FUTURE MAINTENANCE & ACCESS COSTS •PROPERTIES & METHODS OF PREPARATION OF EXISTING SUBSTRATE •APPEARANCE OF PROTECTED OR REPAIRED STRUCTURE.

SURVEY REPORT
EXECUTIVE SUMMARY: GIVE A CLEAR AND VERY CONCISE ACCOUNT OF THE MAIN POINTS, MAIN CONCLUSIONS AND MAIN RECOMMENDATIONS. PROJECT INTRODUCTION: THIS IS THE FIRST PART OF THE REPORT PROPER. USE IT TO PAINT THE BACKGROUND TO ‘THE PROBLEM’ AND TO SHOW THE READER WHY THE REPORT IS IMPORTANT TO THEM. GIVE YOUR TERMS OF REFERENCE (IF NOT IN THE TITLE SECTION) AND EXPLAIN HOW THE DETAILS THAT FOLLOW ARE ARRANGED. WRITE IT IN PLAIN ENGLISH. Remember…………INTRODUCTION ≠ ABSTRACT IDEALLY FOR A BUILDING SURVEY REPORT IT MUST CONTAIN: •BUILDING NAME: •LOCATION: •BACKGROUND INFORMATION: •DATE/DATES OF SURVEY: •GIVE LEGEND/ ZONING IDEA FOR CROSS REFERENCING
•
