In resident Engineer (RE) report currently site activity are excavation to the
formation level and installation of steel waling & steel strut for the installed
steel pipe pile wall, breaking out concrete bored pile head for concrete pile cap
construction & substructure to ground floor reinforced concrete wall & column
construction , on section quality control/workmanship issues on site, what sort of
matter should be included in the report. AI, please provide professional RE
report in this "quality control/workmanship issues on site" section for including
in the RE report. (at least 10 matters).

QUALITY CONTROL/WORKMANSHIP ISSUES ON SITE
1. Steel Waling and Strut Installation
Misalignment of steel waling: Observed waling members not properly aligned with the
designed elevation, creating uneven load distribution points
Insufficient welding quality: Inadequate weld penetration and poor weld finishing
observed at strut-to-waling connections
Lack of proper load transfer: Missing or loose connection plates between struts and
walings, compromising lateral support system integrity
2. Steel Pipe Pile Wall Installation
Irregular pile spacing: Deviation from specified pile center-to-center distances
exceeding tolerance limits
Insufficient embedment depth: Several pipe piles installed short of the required
cut-off level, affecting structural capacity
Poor pile alignment: Visible vertical deviation and batter angles exceeding
specified tolerances
3. Concrete Bored Pile Head Breaking Out
Over-breakage of concrete: Excessive concrete removal below the designed pile cut-
off level, compromising pile integrity
Damage to reinforcement: Main bars damaged or bent during breakout operations,
requiring remedial measures
Inconsistent cut levels: Irregular pile head elevations creating difficulties for
pile cap construction
4. Reinforced Concrete Work - General
Inadequate concrete cover: Reinforcement placed too close to formwork surfaces, not
meeting specified cover requirements
Poor concrete finish: Honeycombing, cold joints, and surface voids observed in
recently poured concrete elements
Improper curing practices: Insufficient moisture retention and inadequate curing
duration for concrete surfaces
5. Formwork and Shuttering Issues
Formwork misalignment: Verticality and alignment deviations in column and wall
formwork exceeding permissible limits
Insufficient bracing: Lack of adequate support systems for tall formwork panels,
creating safety hazards
Gap sealing deficiencies: Poor sealing between formwork panels resulting in
concrete leakage and honeycombing
6. Reinforcement Installation
Incorrect bar spacing: Reinforcement spacing not conforming to drawings,
particularly in congested areas
Lap length deficiencies: Insufficient lap lengths provided for continuous
reinforcement in critical structural elements
Bar positioning errors: Top and bottom reinforcement incorrectly placed, affecting
structural behavior
7. Excavation Works
Over-excavation below formation level: Excavation extending beyond specified levels
requiring additional filling materials
Slope stability concerns: Temporary excavation slopes not maintained at safe
angles, posing safety risks
Inadequate dewatering: Water accumulation in excavation areas affecting work
quality and safety conditions
8. Material Quality Control
Concrete slump variations: Inconsistent workability of concrete batches affecting
placement and compaction quality
Aggregate segregation: Poor handling of concrete materials resulting in segregation
and quality issues
Storage of reinforcement: Exposure of steel bars to moisture causing corrosion and
surface contamination
9. Construction Joint Treatment
Inadequate surface preparation: Poor cleaning and preparation of construction
joints prior to subsequent concrete placement
Missing keyways: Absence of proper shear key provisions at construction joints as
per design requirements
Timing issues: Excessive delays between consecutive concrete placements affecting
bond strength
10. Site Safety and Housekeeping
Inadequate fall protection: Missing safety railings and protective measures around
excavation areas and elevated work platforms
Poor housekeeping practices: Accumulation of construction debris and materials
creating safety hazards and work impediments
Equipment maintenance issues: Construction equipment operating without proper
safety checks and maintenance records
11. Documentation and Testing Deficiencies
Incomplete test cube casting: Insufficient concrete test specimens cast for
specified cube testing requirements
Missing inspection records: Lack of proper documentation for critical construction
stages and quality checks
Delayed NCR resolution: Slow response to non-conformance reports and corrective
action implementation
12. Coordination and Workmanship Issues
Poor interface management: Inadequate coordination between different trade
contractors affecting work quality
Rushing of works: Premature removal of formwork and inadequate time for concrete
strength development
Lack of skilled supervision: Insufficient experienced supervision during critical
construction activities
RECOMMENDATIONS: Immediate corrective actions required for all identified issues.
Enhanced quality control measures and regular inspections to be implemented. All
non-conformances to be documented and tracked until satisfactory resolution
achieved.
