Introduction

To avoid potential

troubles during

construction,

constructors have towork on the solutions

before the problem

comes. With future

events unknown, that iseasier said than done.


8/58

Construction Staging

Construction staging is the logistics of space

allocation for equipment movements and

materials storage, worksite access, temporary

works, provisions for construction workrequirements, including the schematic

organization of the staging areas.


9/58

Construction staging involves strategically dividing the whole

area into different parts, treating each part as one separate

job site, as in first phase, second phase and so on.


10/58

Construction activities progress from one part to the next,

and then to the next, until all parts or phases have been

completed


11/58

In urbanized area or existing facility, construction staging

involves enclosing specific areas while undergoing operations

and shifting enclosure as work progresses.


12/58

Construction staging needs planning of the combinations of

various construction elements procedures, methods,

equipments, technology and available space for each phase.


13/58

Construction Staging

The important factors in planning the

construction staging are:

S U S T A I N

S- site limitationsU- utilities

S- safety

T- traffic controlA- access to work area

I - impacts during construction

N- nature protection


14/58

S - Site limitationsExisting Site Condition

Terrain and landscape affects themovement, supply and transportof materials and workers.

Residents in the vicinity can besource of labor.

Trees, soil, ground and naturalenviron can be source ofmaterials.

Its climatic condition mayinfluence critical scheduling asstorm occurrence can causeflooding.


15/58

S - Site limitationsExisting structures and underground utilities

Existing buildings & structures, utilities within project siteincluding power lines, pipelines, buried cables and sewers.

Existence can delay the work:

Block the movement of workers, equipments & materials

Block the line of sight of the surveying equipments

May conflict with newproject

May require revision ofproject design or relocationof the existing utilities


16/58

S - Site limitationsSpace Allocation

Staging Area

A designated area

where vehicles,supplies and

equipments are

positioned for access

to construction site.


17/58

S - Site limitationsSpace Allocation

Temporary Works

Towers, trestles, scaffolds and

temporary structures

The stability and reliability of the

temporary works is the bottom

line of the quality of the finish

work.

Once done, immediatelydismantled to give way to other

necessities.


18/58

S - Site limitationsSpace AllocationSite Office and Other

Requirements Whenever possible,

provision on site for fieldoffices, toilets, showerrooms, mess hall and restrooms including sleepingquarters shall be providedon site or in the

neighborhood. This cansave transportation timeand cost.


19/58

S - Site limitationsSpace AllocationSpace Allocation for Waste:

Appropriate stockpilesize and location will

facilitate activities,reduce damage tosensitive areas.

Orderliness and safetyof the site, the qualityof the work finish aredirectly related towaste management.


20/58

U - UtilitiesConstruction staging plan should consider

essential utility needs for the project:

Energy Requirements

Water Requirements Drainage Requirements

Communications


21/58

U - UtilitiesEnergy Requ irements

In construction, energy is a

primary commodity. Without

sufficient energy supply, project

can not progress as intended.

Construction staging should

consider power and energy

requirement on site, hourly fuel

demand of the mobile equipmentsand vehicles, power demand of the

tools and machines in the yard,

and others.


22/58

U - UtilitiesWater Requirements

Water supply is a very important

commodity in the construction

site.

Water is used in the concrete

works, earthworks, washing and

sanitary facilities.

Construction staging should

consider the details of water

supply scheme, including its

hourly supply and demand

inventory.


23/58

U - UtilitiesDrainage Requirements Drainage provision should be

considered particularly whenthere is dewatering operation.

Improper sewerage system cancreate chaos in the community.

With field offices and quarters,drainage system is important.

In the absence of a properdrainage system in the area,portable sanitary facilitiesmaybe employed.


24/58

U - UtilitiesCommunicat ions

Communication facility is also

a basic necessity in the

construction site.

The choice of system the site

would use may depend on the

type of works involved in the

project.


25/58

S - Safety Construction staging should

always consider safety inevery activity.

In a construction site

involving various workerswith diverse activities,materials, tools andequipments; the work place

itself is a potential hazard.


26/58

S - SafetyAccidents

can delay,

demobilize,

demoralizeand degrade

construction

projects.


27/58

Murphys Law:Left to themselves,

things tend to go from bad to worse.

Hence, a construction sitehas the normal tendency

to become 4Ds:dirty

disorderly

dense (crowded)

and dangerous


28/58

Practical Ways to keep Construction

Site from becoming 4Ds: 5Ss of Good Housekeeping:

Sort (arrange)

Systematize (organize)

Sweep (clean)

Sanitize (free from dirt and germs)

Self-discipline (practice consistently)


29/58

Hierarchy of Safety:

1. ELIMINATEthe hazard2. If not practical, PREVENT

3. If not practical, CONTROL


30/58

Last line of

control/defense

2. Administrative Control:

Exposure time limitations Safe work practices

Alarms and warning signs

Training and education

3. (Point of contact)Personal Protective

Equipment

Three areas where hazards can be controlled:

SOURCE RECEIVERPATH

1.(Pre-contact) Engineering Control : Elimination/minimization

Enclosure of the hazard

Redirection of hazard


31/58

Engineering Controls

If . . .The work environment can be physicallychanged to prevent employee exposure to

existing and potential hazard,

Then. . .The hazard can be eliminated withan engineering control


32/58

Administrative Controls

If .. .The wayemployees do the job

can be changed, and

exposure to potential

hazard is removed,

Then. . .The hazard

can be eliminated with

administrative control

& others


33/58

S - SafetySummary of PPEs for the safety of construction personnel:

Head protection hard hat, bump cap;

Eye and face protection safety glasses, safety goggles, face

shields;

Ear protection ear plug, ear muffs, canal caps; Respiratory protection filtration respirator, air-purifying respirator,

air-supplying respirator;

Hand and arm protection gloves, hand pads, sleeves;

Foot and leg protection foot guards, safety shoes, boots, leggings;

Fall protection safety belts, safety harness, lanyards;

Torso or body protection vests, jackets, aprons, cover-alls, full-

body suits.


34/58

S - SafetyBasic requirements to effectively

promote safety in a job site

(acronym: SAFE ESCAPE):

Safety personnel

Ample lighting Fire protection system

Electrical hazards checked

Efficient material storage

Structural soundness

Controlled access

Adequate ventilation

Personal protective equipment (PPE)

Excellent housekeeping


35/58

T - Traffic control Construction activities

within a transportation

facility area would

result to traffic

disruption. Construction staging

must prepare a traffic

flow scheme for the

immediate relief ofvehicles traveling the

area during the

execution period.


36/58

T - Traffic control Alternative route or

traffic diversion route

must be provided using

standard trafficengineering system.


37/58

T - Traffic control Ineffective traffic

control scheme

would result to

encroachment of

traffic to the worksite, causing delay to

operations, or

effecting damage to

finished works.


38/58

A - Access to work area Access to work area is a basic requirement.

Controlled access to delicate job or restricted area is

a major concern.

Site access should include access road to the area,

ingress and egress, and probably, isolation of somespecific work areas.


39/58

A - Access to work areaACCESS ROAD

Temporary access road

need to be constructed to

transport materials,

equipment and personnelto the work area.

Access roads should be

properly maintained

throughout the duration ofthe project.


40/58

A - Access to work areaINGRESS AND EGRESS

Controlling entrance and exit of a

construction area is not only for

safety and security, but also for

resource and quality management. The site that is protected from

external influence is cleaner, more

orderly and undisturbed.

Intrusion to job site may disturb the

delicate setting of materials (e.g.,

concrete, tiles) and the quality of

finish (e.g., painting).


41/58

I - Impacts during construction One of the most

crucial concerns in the

construction site are

the impacts duringconstruction operation

particularly when

massive earthworks

and heavily powered

equipments areinvolved.


42/58

I - Impacts during constructionDISRUPTION OF

PEDESTRIAN ACCESS

The disruption of a

pedestrian access route,

may create severe impactto pedestrians.

Whenever a pedestrian

access route is blocked by

the project, an alternate

circulation path shall beprovided as long as safety

warrants.


43/58

I - Impacts during constructionCONSTRUCTION NOISE

Controlling construction

noise can pose special

problems for contractors.

Construction noisemakers can move from

one location to another

and vary in its intensity

throughout the work day.


44/58

I - Impacts during constructionConstruction noise can be

controlled, as follows:

Incorporate noise control

in all phases of project

planning and design,

Buy Quiet Rent Quiet

Equipment

maintenance,

Barrier protection,

Work activity scheduling,

Work quiet awareness.


45/58

I - Impacts during constructionNoise

When its not feasible

to reduce the noise

or its durationuse ear protective

devices such as ear

plug, ear muffs, canal

caps or others.


46/58

I - Impacts during constructionCONSTRUCTION

VIBRATION

Construction activities cause

varying degrees of ground

vibration. Buildings and structures in the

vicinity may react to vibration.

Work which employs

equipment that generateserious vibration impact must

be used with extra care.


47/58

I - Impacts during constructionCONSTRUCTION

VIBRATION

Vibration effects can range

from causing annoyance

to people inside thebuildings, to minor

(cosmetic) damage to

walls and ceilings, to major

structural damage. Special care to old

buildings close to the site

must be observed.


48/58

I - Impacts during constructionConstruction Vibration Mitigation Design considerations and project lay-out:

Route heavily loaded trucks away from residential streets.

Operate earthmoving equipment on the construction lot as far

away from vibration-sensitive sites . Sequence of operations:

Phase demolition, earthmoving and ground-impact operations

so as not to occur in the same time period.

Avoid night time activities.

Alternative construction method:

Avoid impact pile driving in vibration-sensitive areas.

Select demolition methods not involving impact.

Avoid vibratory rollers and packers near sensitive areas.


49/58

I - Impacts during constructionDUST

Common to construction site is the

presence of dust.

Also common to construction site is

exposed soil. When wind picks up

the dry exposed soil and carries itoff, dust become airborne.

Dust can cause the following:

create health problems

degrade the environment

create problems with visibility

damage or dirty property

create unsafe working conditions

D t C t l M


50/58

Dust Control Measures

Dust prevention for construction activities generally seek to

minimize soil disturbance and eradication of loose soil

fines or uncovered earth surface by the following manner: Minimize disturbed surface by reducing excavation size or

number.

Limit dusty work on windy day.

Pave haul road and storage areas. If costly, pave just the

entrance/exit, then gravel the remainder.

Water or sweep the roadway often.

Limit driving speed on unpaved surfaces to 15 kph.

Prevent transport of dusty materials by rinsing vehicles and tightly

covering loaded trucks. Enclose storage and handling areas.

Keep storage piles covered when not in use. Limit the working

face of the pile to the downwind side.

Clean up dusty spills immediately.


51/58

N - Nature protectionAs part of construction

planning, detailed

construction staging

should be sequentially

prepared incorporatingthe environmental

protection requirements.


52/58

N - Nature protectionConstruction staging can

ensure that all land used for

quarrying activity is restored to

its equivalent condition or better

than the original condition

before the commencement of

the operations.


53/58

N - Nature protection

Construction staging can

prevent disturbance of

vegetation or causerehabilitation of disturbed

vegetation.


54/58

N - Nature protectionConstruction staging

plan can avoid pollution

of the air, thwart the

contamination of water

resources and cause aneffective waste disposal

in the construction area

and its periphery.


55/58

Conclusion

Construction staging is crucial

in the over-all performance of

the construction operations.

It is as important as the

construction work itself.

Most of the construction-related

problems in project execution

are direct or indirect result of

insufficient consideration of theimportant elements in planning

the construction staging.


56/58

Conclusion

The important factors in planning theconstruction staging are:

S U S T A I N

S- site limitationsU- utilities

S- safety

T- traffic controlA- access to work area

I - impacts during construction

N- nature protection
