Engineering Services
The professional engineering services offered by this consulting engineers are as follows:

Tectonical and seismo-tectonical investigations, study of regional and site seimicities
 

Preparation of basic geotechnical maps in large, medium and small scales for provinces, cities and suburban areas in national, provincial and regional projects
 

Research on seismo-geotecnical phenomena (such as Soil Amplification, liquefaction, landslide, rockfall, etc...) and preparing seismic hazard zonation maps

Evaluation and analysis of geological, engineering geological and geotechnical problems considering the specifications of the site, including the loading rate, the significance of the project and its risk; and determining the necessity of geotechnical investigations and studies.
 

Geotechnical engineering services on the base of site circumstances and the project’s specifications
 

Geotechnical investigations and ground characterization, including drilling boreholes and performing field and laboratory tests.
 

Geotechnical engineering studies and the necessary technical and economical evaluation, such as the design of shallow and deep foundations, underground structures, ground treatments (grouting, reinforced soil, nailing, micropile, etc…), short-term and long-term stabilization of excavations and trenches, dewatering and control of the underground water level, and evaluating the design effect on the surroundings from the geotechnical point of view
 

Design of light and heavy-weighted structures
 

Retrofitting and performance evaluating of built structures and earthquake (redesign and resistant structures)
 

Design of dams, barriers, channels, water Conveyance tunnels, lateral hydraulic structures, and their construction supervision
 

Design of underground structures (tunnels, water sewerage systems, shafts and artificial caves)
 

Design of quay walls, breakwaters and piers, and supervising their construction procedure
 

Natural hazard and risk assessment (flood, earthquake,...)
 

Assessment of environmental impacts of structures and linear projects
 

Supervision and quality control of structural and geotechnical constructional activities
 

Control tests on construction materials, such as:
Steel (tensional strength, yield point, verifying brand of steel)
Fine and coarse aggregates (grain size, particle shape, material’s durability and quality, water absorption, specific weight etc…)
Cement (physical, mechanical and chemical tests)
Bricks and tiles (compression strength, water absorption, moisture etc…)
 

Concrete technology and quality control tests such as: concrete additives, admixture design, sampling, workability and strength tests on concrete etc…
 

Concrete technology services on specific concretes such as Roller Compacted Concrete, Shotcrete, Fibre Reinforced Concrete, Self Compacted Concrete, Plastic Concrete, High Performance Concrete, Light Weight Concrete, Injection Grouts, etc.
 

Engineering services in the field of watertight systems and injection at tunnels, dams and hydraulic structures.
 

Local soil, concrete, asphalt and constructional material laboratories
 

Destructive and non-destructive tests on concrete and steel structures
 

Geophysical tests including geoelectric and downhole, uphole, crosshole, seismic refraction seismography for investigating physical and mechanical properties of subsurface ground

Field and Laboratory Equipment

Laboratory Equipment:
DKP Consulting Engineers posses all the necessary devices to perform various concrete inspection laboratory services.
All the tests on cement, aggregate, admixtures, grouts, fresh and hardened concrete are practicable by Darya Khak Pay laboratory equipment.

Other in-situ testing equipment for concrete and masonry structures such as drilling (coring) equipment, mortar-brick shear strength test equipment, non destructive testing of concrete structures (Schmitt Hammer, Ultrasonic pulse velocity tester, Cover measurement, ...), grout and slurry tests and etc... are also available for the company.

In the field of geotechnical inspection and laboratory services (soil and rock mechanics), Darya Khak Pay has been qualified by Iran's Management and Planning Organization. Our laboratory is equipped with sufficient number of consolidation, uniaxial, triaxial, direct shear, jackhammer, marshal and other required apparatuses commonly used to examine physical and mechanical properties of soil and construction material, depending on the project's circumstances.


Field Activity equipment:
DKP Consulting Engineers owns seven mobile drill rigs, Ski and DTHs with the maximum capacity of excavation through rock and alluvium. Additionally, we are in possession of complete set of equipment for in-situ tests, such as in-situ shear test, plate loading, CPT, SPT, density tests and borehole pressure meters.
