Penyelidikan Lapangan
Field investigation is a method for obtaining actual technical information about ground and construction conditions directly on site. UP. PPP conducts these investigations to support road and bridge projects across DKI Jakarta, serving both government and private-sector needs.
All field work is performed by competent personnel using calibrated equipment, with results documented in factual data reports.
Sondir & Soil Sampling
Cone penetration testing (sondir) and undisturbed soil sampling to evaluate subsurface conditions at project locations.
Standard Penetration Test (SPT)
In-situ dynamic penetration testing to determine soil density and strength parameters for foundation design.
Coredrill
Drilling and coring of asphalt concrete and concrete structures to extract samples for laboratory analysis.
PIT & Closure Tests
Pile integrity testing and closure assessments to verify the condition of deep foundation elements.
Field Density (Sand Cone)
On-site density measurement using the sand cone method to confirm compaction quality of earthworks and pavement layers.

Retribution FeesField investigation activities carried out by UP. PPP Bina Marga are a critical component of infrastructure development in DKI Jakarta. These on-site technical assessments provide the factual data needed for planning road and bridge construction, as well as maintenance and rehabilitation projects. By conducting cone penetration testing, soil sampling, and other ground surveys, the unit ensures that engineering decisions are based on actual subsurface conditions rather than assumptions. The work supports both government infrastructure programs and private sector development, helping to verify that designs are appropriate for local soil characteristics and load-bearing requirements. All field personnel follow standardized procedures to maintain data quality and reliability.
The results of field investigations directly inform the design and execution of road and bridge projects throughout the province. Data collected from sondir testing and soil sampling helps engineers determine foundation depths, pavement thickness, and appropriate construction methods for each specific location. This technical approach reduces the risk of structural issues and helps optimize project budgets by matching designs to actual ground conditions. UP. PPP coordinates closely with other units within Dinas Bina Marga to ensure that field data is properly integrated into project planning and implementation. The unit's commitment to systematic investigation contributes to safer, more durable transportation infrastructure across Jakarta.
