The project is located in Sultan Qaboos Highway close to the Burj Al Sahwa Roundabout, Rusayl.

The main component of the project:

Sultan Qaboos Street with Seeb Street bypassing Burj Al Sahwa Roundabout under which two ramps are under passing, one is connecting Sultan Qaboos Street with Burj Al Sahwa Roundabout and another is connecting Burj A1 Sahwa Roundabout with Seeb Street.  At the both underpasses there is seepage of water and accumulating on the road and its surrounding which sources are unknown.

Therefore the Muscat Municipality intends to find out sources and reasons of water accumulation/seepage at the two underpasses road and its remedial measures to cater the seepage problems.

According to the TOR, the Scope of Work is detailed as follows:

The Scope of Work as detailed in the TOR includes the following tasks:

• Geotechnical investigations to determine characteristics of underground materials in terms of mechanical properties and permeability along the approach roads, underpass and its surroundings
• Investigations to determine the source of sources of groundwater affecting the roadway and underpass structures
• Analyse the groundwater regime and recommend measures to prevent seepage daylighting in the project area
• Recommend remedial measures to road and surroundings where affected by seepage
• Recommend remedial measures to underpass structures and surroundings where affected by seepage

Based on the above the work outline plan will include the following activities

• Phase A –Preliminary Design
• Phase B - Detailed Design
• Phase C – Pre Contract Quantity Surveying Services
