Methodology

of Rebar Fabrication

& Installation

CUTTING LISTS

Cutting lists means producing shop drawings and

computations of rebar cut length

and bend taking into account a

minimum wastage on

commercial length. It also

means value engineering. For

shop drawings and

computations, it should be

based on the approved For Construction Drawings. It will be submitted for

correction/approval of the

client/s and designers. In these

computations of rebar cutting

lists, minimum wastage is to be

considered from each

commercial length that will be

used in the project.

Only approved materials complying with the standard

specifications & requirements

set by the designer, duly noted

by QA/QC inspector that it has

proper documentation and

passed a series of test

requirements indicating batch

file numbers of materials are to

be use in the fabrication and

installation.

FABRICATION

Cut and fabricate reinforcement bars needed for installation

using the approved rebar cutting

list and staking plan as the

basis. Prior to fabrication,

double check actual clear

lengths based on actual site

condition with respect to the

approved cutting list, make

adjustments as per actual

measurement if necessary.

The bar will be cut based on cut length from a commercial

length using a bar cutter. If the

bar needs to have a hook, it will

be bended using a bar bender

until the degree of bend will be

met. Note that each machine has

a maximum bar diameter to be

(

cut or bend. Bar diameter higher

than the allowable diameter of

the machine should not be cut

or bend on the machine to

prevent machine breakdown.

INSTALLATION

Haul fabricated bars from the fabrication area to the site for

installation.

It will be assisted by a mobile crane or a tower

crane. Hauling small items such as

ties and chair bars, an improvised basket

should be used.

Install necessary scaffoldings and lifelines prior to installation of rebar especially at

columns and perimeter beams and girders. Use

necessary personal protective

equipments such as safety harnesses and

gloves.

In installing reinforcement bars for mat footings, bottoms bars

are to be installed first then

chair bars are to be position in

place before the top bars are

installed.

For columns, a tie is tied on the footing as a guide in the

installation of starter bars. Once

the corner vertical bars are put

in place, a set of ties are to be

tied up to hold the vertical bars,

then the remaining vertical bars

are to be installed. After that,

ties will have to be completed.

Vertical bars are to be spliced

only at the splicing zone

required by the structural

designer. For columns, it should

be at the middle H/3 of the

column where H is the clear

height of column. Prior to

splicing, ties up to the next floor

level should be installed. Then

the vertical bars are to be

lapped, and fabricated concrete

spacers are to be put in place

before the forms are installed.

Same methodology with shear

walls and retaining walls.

For beams and girders, Top and bottom bars should be put in

place and tied up together at the

center of span for easier

placement of ties. Once the

required numbers of stirrups are

put in place, it will be tied up

with the main bar with correct

spacing based on the approved

cutting list. Rebars are to be

spliced only at the splicing zone

required by the structural

designer. For top bars, splicing

should be within the center but

will not go beyond L/4 of clear

span from the face of column.

And for the bottom bars, the

splice length center should be

0.22L from the face of the

column. Extra top bars should

go until L/4 from face of

column and whichever length is

larger from the adjacent span

will govern. Extra bottom bars

are placed 0.165L of clear span

from each column face. Stirrups

on splicing will have spacing

100mm or as it is stated on the

designers general notes. Shear bars of the same diameter of the

main bar is installed if there are

construction joints. To have a

correct concrete covering for

the bar, a fabricated concrete

spacers are tied to the bars.

For slabs, bottom bars are to be placed first. All necessary

embedment for electrical,

mechanical, fire protection, etc.,

are to be installed by the trades

in charge prior to the

installation of top bars. Then

concrete spacers are to be

placed between the bottom bars

and the slab forms. Also, a chair

bar will be place between the

bottom bars and the top bars.

QUALITY ASSURANCE

The fabrication and installation will be strictly under the

supervision of an appointed

rebar

supervisor/foreman/leadman to

implement a quality work. He

will implements monitor and

check fabrication and

installation considering

approved cutting lists, proper

housekeeping and safety.

If there are comments by the management on the work, it will

be immediately be rectified.

MASONRY

METHODOLOGY

CHB LAYING

Prepare area for layout of concrete hollow block ( CHB ) wall Layout

all CHB wall in accordance with the

approved plans and shop

drawings.Upon completion of all

layout, straightened all dowels or

drill vertical and horizontal starter

bars with epoxy if not provided.

Set out one layer of starter block on all laid out areas prior to

commencing of all CHB

laying,Areas with waterproofing and

with CHB wall pour 75mm thick

Upstand wall ( Zocallo ).After

completion of the starter block, start

laying the CHB and fill all cells as

per structural requirements.

Install Styrofoam at end of CHB wall between reinforced columns, beams

and walls, sealant with backer rod

follows after completion of CHB

wall.

Provision of stiffener beam above 3.00 meter high wall and stiffener

column wider than for 4.00 meters

width wall.

Recheck layout and plumbness of CHB wall in relation to door and

window openings.

Place all plastering guide and then request for approval with the concern

departments prior to plastering

works.With the approval proceed

with the plastering work.

Proposed Rectification Methodology of

Wall with Short Horizontal Dowels

Determine the area of chb wall to be cut ,were the rebar dowels is short.

With the used of a Grinder cut the

determined area of chb to be

removed.

Demolished the chb until the rebar is exposed.Clean the rebar, it must be

free of concrete littans.

Spliced the rebar with the standard length of splicing to meet the

required length for dowels.

Replaced the chb and fill it with mortar.

PLASTERING

Check all areas to be plastered base on latest FCD and approved

drawings.

Prepare all documents to be submitted/routed/signed/ by all

concern prior to commencing

plastering to insure all utilities are in-

placed.

After obtaining the approval, prepare plaster bases and substances for

direct application of plaster ,

removing loose materials and

substances which might impair the

work.

Immediately apply scratch coat on areas to be plastered to insure

maximum bonding of plastering to

CHB wall.

Provide concrete button or concrete guide strips to insure alignment and

plumbness of the finish plaster

following the surveyors layout and

set-out points.

Allow scratch coat to dry then apply the finish coat following the guide

buttons or strips using straight

aluminum bars to specified smooth

trowel finish.

Clean the area and moist cure the completed plastered surfaces.

Quality Assurance

Program

I. Jobsite Quality Control

Trained project Supervisor / General

foreman will supervise and control the

quality of works, monitor if the rebar

that have been installed meet the

technical requirements of the structural

supervisor and in compliance with all

the requirements appeared in the

approval of cutting list.

II. Monitoring and Control on/offsite activities

The fabrication in charge will check

the actual cut length to see if they

match in the cutting list and fabrication

requirement to avoid the confusion and

error during the installation of rebar.

III. Cutting and Fabrication

Fabricate desired diameters of rebar to

desired length using approved rebar

cutting list and structural framing plan

as the basis of fabrication. Double

check actual clear length of the are of

installation on site with respect to the

approved cutting list , make sure

adjustments as per actual measurement

if necessary. Also maximize the

materials such that the total length of

rebars is utilized and wastage is

minimized.

IV. Briefing of Installer & Steelman

In order to avoid the mistakes during

the installation, the steelman will be

advised of all the detailed

requirements, regarding rebar

installation. Also , they will be

provided a copy of approved cutting

list.

V. Installation

The installation works will be strictly

under the supervision of the appointed

site rebar supervisor/ general foreman,

to follow the details. Also, installed

rebar as per approved cutting list,
