Initial Site Assesment
The success of a project starts in the
planning of the project.

Our initial site assessment process considers the suitability and cost effectiveness of the project, addressing both on-site characteristics as well as utility interconnection potential, the likelihood of project approval, the degree of project difficulty, the cost of potential upgrades, and evaluating the project time-frame. We can also assist project developers in identifying and qualifying project sites and opportunities while providing fatal-flaw analysis.

In conclusion of the initial site assessment, we can provide PV system sizing, a site plan, multiple array layouts, a system electrical single line, along with the specifics found below:

Rooftop PV System site assessment
  • Conduct facility assessment including detailed field drawings of existing conditions.
  • Provide for engineering review of the building's structural capability to accept the additional loading of a PV system.
  • Provide for the assessment of wind loading requirements.
  • Conduct solar access and shading studies.
  • Perform assessments of existing electrical service and distribution on-site and within facility.
  • Determine conduit routing, inverter placement, and PV system interconnection location and method.
Ground Mount System site assessment
  • Direct, coordinate, and oversee civil/environmental/geo-tech engineers' on-site assessment considering factors impacting site suitability, development, and utilization regarding:
    • Zoning and easements.
    • Environmental, archeological, and wetland concerns.
    • History of use and prior contamination.
  • Determine site access, development costs, and construction logistical issues.
  • Examine activities on adjacent land that could adversely impact the solar project.
Utility Interconnection

Take advantage of the opportunities in solar distributed generation.

Whether ground-mount or roof-mount we can help supply your solar production to the grid through assessing the utility interconnection requirements at your site and within the local distribution area by:

  • Determining the nature and capacity of the existing distribution feeder.
  • Certify the distance to the substation.
  • Evaluate the nature and cost of potential utility upgrade requirements.
  • Provide insight into the amount of DG already in place and the queue on the distribution feeder and substation.

We also provide for:

  • The development of collateral technical materials for utility interconnection applications including signed-and-sealed electrical plans.
  • Liaison with the utility on technical aspects of interconnection including in-depth, point-by-point assessment.

BIM Modelling Services

We are trusted by some of the best known design-build contractors of The USA, the UK, Canada, Australia and also Mechanical, Electrical, Plumbing and Fire firms across the world BIM Modelling Services. We leverage the latest technology solutions and design software from Autodesk, to create digital representations, customized in line with our client's requirements.

BIM (building information Modelling) is a shrewd 3D model-based technique that gives architecture, engineering, and production (AEC) experts the perception and tools to extra efficaciously plan, design, construct and manipulate buildings and infrastructure.

We are the team of very well experienced architects, Civil engineers and draftsman's and we offer a comprehensive range of BIM services to the Architectural, Structural, MEP/HVAC & Facade domains for effective pre-construction planning. Our in-house team of 35+ proficient BIM engineers is capable of offering services ranging from the development of BIM models from 2D files, documentation in BIM, clash detection to delivering 7D BIM models for infrastructure management.

Through the usage of Autodesk Revit Architecture, Revit MEP and Revit shape, we will create construction planning design records for a various range of projects with the same family of software. At the same time as we favour this Closed BIM approach, we are also capable of work within Open BIM environment which uses common report formats consisting of IFC (industry foundation classes) to reduce software interoperability issues and delays.

We also provide BIM Modelling services to impartial stakeholders involved in a BIM project that may lack the understanding of creating and managing BIM models. In addition to 3D parametric modelling, we provide 4D and 5D Revit BIM services to our customers.

We provide BIM drafting services, BIM consulting services, 3D BIM modelling services and BIM 4D modelling services using Autodesk's Revit BIM platform to enable design modelling from pre-construction concept stages through to detailed construction stages. Whilst we generally favour a Closed BIM approach, using Autodesk Revit Architecture, Revit MEP and Revit Structure, we are also able to work within an Open BIM environment to provide 3D BIM services.
