1. GEOTECHNICAL RESPONSIBILITIES
-
D Wall Panel Layout Design & Approval
: Prepare detailed D Wall (diaphragm wall) panel layouts, coordinating closely with the site team and rebar team to ensure layout feasibility. Engage with the client to finalize designs and obtain necessary approvals. -
Trench Stability & Dewatering Scheme
: Review and verify the trench stability and dewatering schemes for the D Wall. Manage design checks and secure client approvals, ensuring that on-site conditions align with approved designs. -
Site Proposal Analysis & Technical Submittals
: Analyze geotechnical site proposals and collaborate with HQ-Design to develop comprehensive technical submittals. Address any modifications required for client approval. -
Geotechnical Factual Reports
: Conduct geotechnical field investigations, including borehole studies along the diaphragm wall alignment at project sites , compiling factual and interpretive reports for submission to the client. -
Depth Reduction Proposals
: Develop and submit proposals to reduce D Wall depth in hard rock zones, considering site-specific trenching challenges and technical requirements. Create backup documentation for client review and approval. -
Coordination with GTI Site Team
: Provide technical guidance to the GTI site team, ensuring drilling activities align with technical and client standards. Oversee drilling activities and depth confirmations as per requirements. -
Drilling Activity Monitoring & Piezometer Installation
: Track daily drilling operations for piezometer installations, compile data for future reference, and monitor slurry properties during bentonite circulation for quality assurance.
2. SITE COORDINATION
-
Documentation & Revision Updates
: Keep the site team informed of recent revisions to technical submissions, clarifying any layout or depth-related adjustments. -
Issue Resolution:
Address queries related to D Wall panel layout, structural elements, and depth requirements, providing guidance to site personnel. -
Structural Element Importance
: Emphasize the critical role of each structural element in maintaining overall design integrity, explaining these aspects as required for site awareness.
3. SURVEY COORDINATION
-
Final Alignment Checks
: Collaborate with the survey manager to verify the alignment of D Wall panels, checking coordinates against reference points and ensuring layout accuracy. -
Daily Alignment Updates
: Provide continuous updates on any adjustments to the panel layout alignment, ensuring synchronization with the latest survey data.
4. QUALITY ASSURANCE
-
Technical Support for Quality Verification
: Offer technical support to the quality team, overseeing the verification of CHSL (Cross Hole Sonic Logging) reports. -
Method Statements & Approvals
: Draft and update method statements for geotechnical investigations and shear pin installation, addressing client feedback and obtaining approval. -
Slurry Monitoring
: Conduct day-to-day monitoring of slurry properties during bentonite circulation to ensure adherence to quality standards. -
Client Communications
: Manage client-related technical communications, including handling TQ (Technical Queries) related to shear pin casing and other requirements.
5. PLANNING & PROGRESS TRACKING
-
Variance Analysis:
Create variance statements to assess deviations from the tender specifications to actual performance and budget. -
Progress Summaries
: Compile summaries that track daily D Wall construction progress, providing insights into project completion rates. -
GFC Requirements
: Clarify technical requirements for Good for Construction (GFC) drawings as they pertain to geotechnical elements, ensuring alignment with project specifications.
6. DRAWING AND COMMUNICATION INTERFACE (DCI)
-
Drawing Management:
Track incoming GFC drawings and manage the transition to working (output) drawings, ensuring version control and clarity for implementation. -
Client Input Updates
: Address and clarify any changes in client-provided input drawings, maintaining accurate records for day-to-day project tracking.
7. CLIENT COORDINATION
-
Weekly Design & Progress Meetings
: Participate in weekly meetings with client , presenting design status, technical queries, and progress updates. Collect feedback to enhance execution planning. -
Technical Constraint Management
: Address site-specific constraints, technical challenges, and propose modifications based on client feedback in ad hoc meetings. -
Real-Time Approval Coordination
: Attend and facilitate client meetings on new design proposals or drawing changes, ensuring timely approvals and preventing delays in site activities. -
Site Activity Authorization
: Manage client interactions regarding layout adjustments or depth modifications, securing approvals to proceed with site activities.
