BUILDING INFORMATION MODELING(BIM)

engineers, contractors, developers, and building owners – to sync together allowing them to view the model

in different ways and seamlessly share information.

The BIM Project Execution Planning guide provides a structured method to plan the implementation of

Building Information Modeling on a project. The procedure includes the following four steps:

1) Identify high value BIM uses during the projects planning, design, construction and operational phases.

2) Design the BIM execution process by creating process maps.

3) Define the BIM deliverables in the form of information exchanges.

4) Develop the infrastructure in the form of contracts, communication procedures, technology and quality

control to support the implementation

BIM Uses are categorized into five primary purposes:

1) Gathering,

2) Generating,

3) Analyzing,

4) Communicating and

5) Realizing

The various stages for BIM are:

Conceptual or schematic design

Preliminary design

Design development

Construction documents and details

freedom, to explore more design options, to make better informed design decisions, and to

predict costs and performance. Design and construction documents are automatically coordinated,

eliminating errors and omissions. Architectural and AE firms can deliver better buildings on time and on

budget, thus improving client services and increasing revenue – business‐critical benefits in today’s

competitive environment.

We perform seamless integration between design, engineering, analysis, construction, and operations for

the entire life cycle of facilities. we bring together multi‐disciplinary work groups and global teams in a

managed environment, allowing them to build as one.

➢ Conversion of 2D drawings to 3D BIM Architectural models➢ Construct ability Review of Design➢ BIM Architectural Coordination models➢ Bidding Marketing Presentation models➢ Pre‐construction Site logistic models

Structural BIM Services

As part of Structural BIM, we provides seamless integration between design, engineering, analysis,

construction, and operations for the entire life cycle of facilities. We have comprehensive documentation

and building information modeling (BIM) serving the needs of structural engineers, designers and BIM

practitioners through accurate document generation and integrated project delivery.

● Detailed Construction drawings.

● 3D Models Preparation (Steel, Wood and Concrete) from the drawings.

● Shop drawings of different structural elements including beams, columns, intels, roof

frames, shelf angles, bracing and wall partitions.

● Planning and cost estimates for Bidding, Construction materials procurement and

practical construction.

● 3D Modeling and Erection drawings for virtual construction management.

● Structural design and construction documentation for structures in steel, concrete and

timber

● Integrated analytical model with finite elements, nodes, boundary conditions and

member releases, loads and load combinations

● Parametric, dimension‐driven creation and modification of structural components

● Automatic user‐definable cutbacks and coping of intersecting members

● Quantity takeoffs, member schedules, volume and weight analysis, center of gravity,

and other reports

We have the ability to automate and synchronize the creation of construction documentation

across a project. This provides a significant time savings over a 2D workflow. The construction

documentation is easily customizable allowing for incorporation of standards.

With Structural BIM, Stake holders can access timely information across multidisciplinary

project teams whether they are working in a single office or distributed across many offices.

MEP BIM Services

MGSPL provides comprehensive 2D MEP Drafting Services for residential houses, buildings,

hospitals and factories etc. as part of its Mechanical Electrical Plumbing services.

Our MEP Services are supportive of light and energy conservation and green energy as we plan

and design accurate Load Calculation, and electrical requirements as per different projects. Our

team of adept MEP modelers can create tailored MEP drawings and specifications with detailed

layout sand models.

We create and design layouts based on the input provided in the form of AutoCAD files, JPG

images, PDF documents, Revit files and hand‐drawn sketches.

Our comprehensive MEP Services include:● Virtual 3D Model Creation● 4th Dimension of Time● Project Information Extraction● Clash Detection and Risk Mitigation● Energy Simulation for Different Projects● Precise, high‐quality construction documents

PHOTOGRAMMETRY

PHOTOGRAMMETRY

It is a Technology of obtaining accurate data through the process of

measuring and Interpreting photographic Images. Planimetric features (roads,

building, hydro, vegetation, utilities etc) and contour interval will be collected based

on the map and photo scale of the Projects.

We do the following services using Client Input Imageries and deliver the output

according to the client requirements.

� DEM Generation

� Stereo Compilation

� DEM‐DTM Extraction

� Contour Generation

� Ortho Generation

LiDAR(Light Deduction And

Ranging)

measures properties of scattered light to find range and/or other

information of a distant target. It is Commonly known as Laser

Radar. LiDAR is based on the transmission of relatively short

wavelength laser light and recording the amount of light

the terrain. LiDAR is not only replacing backscattered from

convential sensors but also creating new methods with unique

Properties that could not be achieved before.

• Types of LiDAR

• Airbone LiDAR

• Terrestrial LiDAR

• Mobile LiDAR

How the LiDAR Works:

The LiDAR Technology uses laser beam to scan the earth surface.

Laser Scanner mounted in aircraft emits laser beams with high frequency

and receives the reflected beam.

Time difference between emission of laser beam and reception of the

reflected laser signal is recorded to get the distance (range).

High frequency rotating mirror placed in-front of the laser converts this

laser into a laser scanner.

GPS data recorded in air and on ground (DGPS base stations for every

25kms) determine aircraft position.

IMU record attitude variations (pitch, roll, yaw) of the platform for carrying

out attitude corrections for the laser beam.

In other word this technology involves the use of pulses of laser light

towards the ground and measuring the time of pulse return. The return time for

each pulse back to the sensor is processed to calculate the variable distance

between the sensor and the various surface present on (or above) the ground.
