Project Context
This project involved the implementation of a stormwater drainage solution along the Corredor Norte highway, centered around a reinforced concrete box culvert (cajón pluvial) and associated stormwater pipelines.
The objective was to safely convey surface runoff beneath the roadway and adjacent slopes, integrating structural, hydraulic, and geometric constraints within a highly controlled highway environment.
Tembok participated as a subcontractor, supporting the project through technical coordination, detailed plan development, and execution facilitation.
Role & Responsibilities
Tembok was not the structural designer of record.
All structural calculations, reinforcement design, and performance specifications were developed by a licensed structural engineer.
Our role focused on bridging design intent and field execution, including:
- Development of detailed construction drawings based on approved structural calculations
- Coordination of box culvert geometry, elevations, and interfaces
- Definition of stormwater pipeline alignment and profiles for field layout
- Translation of structural design into execution-ready documentation
- Technical support to the client during construction coordination
This role ensured that the designed system could be accurately built on site, with minimal ambiguity and reduced execution risk.
System Overview
The drainage system consisted of:
- A reinforced concrete box culvert, designed to accommodate stormwater flows and structural loading
- Integrated stormwater pipelines, aligned to connect upstream and downstream drainage networks
- Concrete cover slabs and access elements to support maintenance and inspection
The plans defined both plan and profile views, as well as typical sections, ensuring clarity across excavation, formwork, reinforcement, and concrete placement stages.
Coordination & Constructability Logic
A key focus of our involvement was constructability.
This included:
- Verifying alignment continuity between pipelines and the box culvert
- Coordinating elevation transitions to avoid hydraulic discontinuities
- Ensuring access openings, cover slabs, and reinforcement layouts were execution-feasible
- Supporting the client in sequencing decisions within a live traffic environment
Rather than redesigning, the work emphasized making the design buildable and predictable.
Outcome
The resulting documentation and coordination effort enabled the execution team to construct the stormwater system with confidence, preserving design intent while adapting it to real-world site conditions.
This project reflects Tembok’s strength as a technical facilitator, capable of translating complex structural designs into coordinated, field-ready infrastructure solutions.
