 Richa Steel structure is an ideal solution for High Rise applications as today in urban
Infrastructure there is a space crunch and such buildings are an appropriate solution to this
problem and are cost effective too due to optimized use of steel.
 Steel Buildings can be built as per architectural design for optimized energy requirement,
such as Natural cooling, solar gains & natural day light
 These buildings incorporate a high level of services which can be easily interfaced within
our system: Air conditioning system ducts, flooring, electric power plants for essential
facilities , fire protection system and all other Mechanical and electrical services easily
designed in our Structural system

 Better quality control as manufacturing takes place under controlled quality system in plant
 Flexibility in selection of member section or can be made from built up
 Mass Production resulting in cost control and highest degree of quality
 Excellent accuracy of product dimension within close tolerance as per code requirement
 Just-In-Time Logical Delivery
 Faster erection at site
 Easy to fabricate in any shape for any application
 High load bearing strength and excellent ductile properties
 Cost effective
 Eco-friendly

PROCESS OF MANUFACTURING
STEEL STRUCTURES

FABRICATION
Structural steel members are fabricated by precisely cutting, sharing, punching, drilling, fitting
and welding in order to produce the configurations detailed in the shop drawings. Each member
is labeled with a piece mark, length, and job number for identification.

LABELLING
Once fabricated, each finished structural steel member is labeled. In this case the fabricator
labels each steel member with its piece mark, sequence number, and the last two digits of the
job number. Richa uses specific labeling practices. In the image, the label color is yellow to
differentiate it from previous labels. Labeling of the steel pieces is crucial because it helps
identify members on the job site.

STORAGE
After fabrication, finished structural steel members are stored in the storage yard. The yard is
properly organized and it makes easier to transport steel to the site in phased manner. Steel
structures are stored according to erection sequence. Sequences define areas of the frame
and are used to organize their delivery and erection. The practice of planning and storing by
sequence improves the efficiency of loading, delivery, offloading and erection.

ANCHOR BOLT
PLAN
One of the first drawings prepared by the detailer is the Anchor Bolt Plan. This
plan guides the foundation subcontractor in the placement of anchor bolts. It
contains horizontal and vertical information for placement of anchor rods, as well as
dimensions and elevations of leveling plates (if used).d).

ANCHOR BOLT
SURVEY
Before the erection process started, anchor bolts and leveling plates are surveyed to check if they
are correctly positioned. If anchor rods are improperly located, they are corrected by the
foundation subcontractor before the erection process may start. The surveyor uses a total station
to determine the horizontal and vertical location of each leveling plate and anchor bolts.

ERECTION
PROCESS

ERECTION TEAM
The Erection Team consists of One Project Manager, One Foreman, 3-4 Iron workers for
hooking steel, three to four iron workers connecting steel and a crane operator.

CRANES
Cranes are selected on the basis of cost, availability, speed, reach and capacity. There are
many configurations and sizes of cranes available.

UNLOADING &
SHAKEOUT
Upon delivery to the job site, fabricated steel unloads and places on wood or steel blocking.
The blocking allows for chokers to be attached to each member for subsequent hoisting and
erection. Shakeout of structural steel takes place after unloading. Shakeout is the process of
sorting the steel pieces on the site so that they can be efficiently erected, and involves
organizing and spacing each structural steel piece.

ERECTION
DRAWING
This is the erection drawing of floor framing for a project. The numbers one and two inside the
red hexagons on each side of the red line indicates the sequence number for each part of the
structure. The piece marks on the drawing matches those on the beams, girders and columns
and are used to locate and orient each member during erection.

SEQUENCE

2. INSTALL BEAMS AND GIRDERS
3. PLUMB STRUCTURES
4. COMPLETE ALL CONNECTIONS (TIGHTEN) INCLUDING BRACING
5. GROUT COLUMN BASE PLATES

FIRST COLUMN
This is the first column being hoisted into position. Using ladders, iron workers temporarily
bolted the column. Prior to erection, the erector must consider column stability in accordance
with safety standards and the AISC Code of Standard Practice.

SEQUENCE
COLUMN

BEAMS
Main girders are hoisted after the columns. Beams are then hoisted and connected to the
girders.

PRILIMINARY
BOLTING
The connector uses pins to align the holes between structural steel members being connected.
Then several bolts are placed and temporarily tightened with spud wrench. At least two bolts
per connection are used to temporarily fasten each connection.

HAND SIGNALS
Teamwork and communication are important when erecting steel. Iron workers use hand
signals to communicate with the crane operator.

PLUMBING
Turnbuckles are a common part of the bracing system. A turnbuckle is a device that usually
consists of a link with screw threads at both ends that is turned to bring the ends closer
together. Using several turnbuckles connected to the temporary bracing, the steel frame is
shifted until it is vertically aligned.

METAL DECKING
This is a view (right 1st image) of the welding used to fasten metal deck to the
structure.

PERIMETER
SAFETY CABLES
On multi-storey structures, perimeter safety cables are installed at the interior and exterior
perimeters of floors and openings as soon as the metal decking has been installed.

SHEAR STUDS
This is a view of the welded studs. Shear studs are tested to ensure that they are correctly
welded to the structural steel members in compliance with the bend test of the AWS D 1.1
Structural Welding Code.

TEMPORARY
BRACING
Temporary bracing is used to provide temporary lateral stability to the structure and to plumb
up the frame. The temporary bracing is removed once the structural steel frame is secured.

FINAL BOLT UP
After a section of the structural frame is assembled and vertically aligned, iron worker
permanently fastens the structural steel members with additional bolts. Tension controlled
black bolts of SS 8.8 grade are widely used. Final bolt-up is performed using a torque wrench.
The wrench stops automatically when the bolt shears at a tension control groove indicating that
the required tension is reached.

SLABS
Floor slabs are poured after the structural steel frame is secured to the vertical masonry shafts.
After reinforcing steel and concrete is placed, the slab is leveled and finished.
