Case Study
Mahshahr Taxi Parking Facility
A 4,000 m² transport parking roof in Bandar Mahshahr where sandwich panel layout, drainage paths, gutters, and sealing details had to work together under coastal exposure.
Verified scope: sandwich panel roofing, drainage coordination, gutters, flashings, downspouts, and installation checkpoints.
Case Study
Project snapshot
Project challenge
The parking facility needed a durable sandwich panel roof for a high-use transport environment in Bandar Mahshahr. The useful engineering challenge was not only panel supply; it was keeping rainwater movement predictable through slopes, gutters, flashings, downspouts, and sealed transitions in a coastal climate.
- Coastal exposure and corrosion-aware detailing
- Continuous drainage path from roof surface to downspouts
- Waterproofing continuity at flashings and panel laps
- Controlled installation sequencing for a 4,000 m² roof
Engineering decision
SIPANEL coordinated the sandwich panel roof as a complete drainage and weather-protection assembly, aligning panel layout, gutter positions, downspouts, flashings, fastening, and sealing checkpoints.
The engineering decision was to treat drainage as part of the roof system instead of a later accessory. Slopes, water-flow paths, gutter locations, and panel alignment were coordinated before installation.
Sandwich panel roofing was selected because it combines fast enclosure, lightweight insulated covering, and controlled lap/seal detailing suitable for a transport parking facility.
Roof panel layout, gutters, flashing lines, and downspout positions needed to be coordinated with the supporting structure before site installation.
Execution detail
Installation sequence
Execution followed an ordered sequence: confirm roof references, install panels with alignment checks, set gutters and flashings, coordinate downspouts, then verify fastening and sealing at water-sensitive interfaces.
Procurement control
Panels, flashings, gutters, sealants, fasteners, and downspout accessories were controlled as one accessory package matched to the approved roof layout.
Coordination with site team
The site sequence kept water-management components aligned with panel installation so drainage details were not left for late-stage correction.
Quality checkpoints
- Panel alignment and lap verification
- Gutter slope and downspout continuity review
- Flashing and sealant inspection at edges and transitions
Measured result
Risks controlled before publication
Water accumulation
Slope, gutter, and downspout coordination reduced the chance of standing water on the roof.
Roof leakage
Panel laps, flashings, and sealant points were treated as inspection checkpoints.
Coastal durability risk
Accessory coordination and sealing details were selected with Bandar Mahshahr exposure in mind.
Improper drainage flow
Water paths were reviewed before installation instead of being adjusted only on site.

32-Bed Military Hospital
Raz & Jargalan, North Khorasan, Iran
- Challenge
- During the COVID-19 emergency, a fully operational 32-bed military hospital was needed from excavation to readiness in under 50 days, requiring full EPC coordination.
- Engineering decision
- Engineering teams coordinated full EPC delivery — from excavation and structural construction to sandwich panel envelope, internal partitions, and final readiness — within an emergency timeline.
- Result
- A fully operational 32-bed military hospital was delivered from excavation to readiness in less than 50 days during the COVID-19 emergency.
Ahvaz Airport Passenger Terminal
Ahvaz, Iran
- Challenge
- The passenger terminal included a curved front architectural feature where the covering had to bend in a perpendicular direction. That made geometry control, substructure alignment, aluminium panel layout, ZIP-TECH transitions, and final visual quality the main execution risks.
- Engineering decision
- The engineering decision was to control geometry first: define curved references, coordinate panel and roofing interfaces, then execute the covering without interrupting the architectural line.
- Result
- 4,000 m² of ZIP-TECH and aluminium cladding were executed while preserving the curved architectural form and final visual quality.
Mehrabad Aircraft Hangar
Tehran, Iran
- Challenge
- The hangar application required accurate sandwich panel covering over a continuous curved structure. Installation access, panel alignment, substructure coordination, and roof-wall transitions all affected weather protection and visual continuity.
- Engineering decision
- Engineering teams defined installation references from the hangar geometry, coordinated support points, and reviewed transition details before site installation.
- Result
- A 5,000 m² sandwich panel covering was executed while maintaining the continuous curved form of the aircraft hangar.
Kermanshah Industrial University Petroleum Faculty
Kermanshah, Iran
- Challenge
- The petroleum-faculty building required structural glass facade connections that could tolerate relative movement in the primary structure and reduce the risk of transferring displacement into brittle glass panels.
- Engineering decision
- The engineering decision was to separate glass performance from uncontrolled structural movement by using connection details that reduce stress transfer into the panels.
- Result
- Approximately 1,000 m² of structural glass facade was executed. The project record states that the facade reportedly remained without glass damage during the Kermanshah earthquake in the 1390s Solar Hijri decade.
