History

NESPAK was established in March 1973 as a

private limited company owned by the

Government of Pakistan.

Sheikh Irshad Ahmad who worked in WAPDA as

General Manager Design was the first Managing

Director. Most of the professionals at the initial

stage were from WAPDA on deputation and from

the private sector.

The first project handled by NESPAK was the

Left Bank Irrigation Tunnel at Tarbela Dam.

Affordable Low Cost Housing

Design Strategies, Building Materials & Construction Techniques

• Optimizing the available space in Architectural Design, considering all the relevant

requirements for healthy living while minimizing circulation space.

• Careful preparation of building specifications, keeping the project cost within range and

by adopting effective construction systems.

• Achieving Energy Efficiency by devising creative design ideas in planning and design,

building orientation, built form, size and arrangement of openings & building materials

along with landscaping.

• Pre-Fabrication – for Structural Building Components such as Hollow Core Slabs, Pre-Fab

Beams and Columns, Wall Panels, Masonry Units

• Standardization of Finishing Materials and Building Components such as Doors, Windows,

Kitchen Cabinets, Wardrobes etc.

• Confined Masonry is a construction system where the

walls are built first, and the columns and beams are

poured in afterwards to enclose (confine) the wall.

Confined Masonry

57

Concept

• The walls are tied down to the foundation.

• The ties work like a string around a parcel.

• Confined Masonry

• Walls are anchored to

the frames through

indentation.

• Additional re-bars will

improve anchoring

• Reinforced Concrete

• Walls are usually not

anchored to the frames

and will fall out.

Later anchoring of walls

can be difficult

▪ Conventional Construction

▪ Modern fast construction technologies

72

Conventional Construction

▪ Reinforced Concrete

▪ Special moment resisting frame

▪ Load Shear walls

▪ Dual system

▪ Building frame system

▪ Structural Steel

▪ Gable or portal frames structures

▪ Trussed structures

73

Fast Construction Technologies

▪ Technologies based on insulated formwork filled with

reinforced concrete.

▪ Technologies based on inner core of insulating material

with outer structural skin of reinforced concrete or

cement sand mortar.

▪ Pre-engineered structural steel buildings comprising

steel skeleton and cladding of sandwich panels.

▪ Conventional Precast Concrete Construction.

74

Insulating Panels Sandwiched in

Concrete or Cement Mortar

➢ The basic unit comprises four to six inch thick sheet of

insulating material with 1”x1” light gauge wire mesh one

both side. The wire meshes are interconnected with light

gauge trusses running across the panel thickness.

➢ The panel is erected over foundation and concrete or

mortar is sprayed over it under pressure.

➢ The roof may be constructed using similar panels or

conventional wooden or steel truss may be provided.

75

▪ The structural strength depends upon external and

internal concrete layer requiring careful structural

design and excellent workmanship at site.

78

Insulated Formwork

▪ The basic unit comprises interlocking hollow blocks of

insulating material.

▪ The blocks are placed one above other on an engineered

foundation.

▪ The required steel reinforcement is placed inside the box.

▪ The blocks are filled with concrete of specified strength.

▪ External and internal wall finish is required to protect

insulation material and to achieve a pleasing appearance

of finished structure.

▪ Flat roofs may also be constructed using roof or floor

forms of same insulation material. Conventional wood or

steel truss may also be used with this system.

79

▪ The structural strength depend upon infill reinforced

concrete which can be designed to resist the specified

earthquake intensity.

Insulated Formwork

80

Cold Formed Light Gauge Buildings

▪ The structural system comprises steel frames; factory

fabricated and shipped to site for erection.

▪ Wall cladding and roofing comprise insulating material

sandwiched between corrugated pre-painted sheets.

81

Cold Formed Light Gauge Buildings

82

Cold Formed Light Gauge Buildings

▪ Structural strength depends mainly on gable or portal

frames which can be accurately designed to withstand

earthquake of specified intensity.

83

Conventional Precast Concrete Construction

▪ Columns, beams, wall and roof panels are pre-fabricated

in factory and erected at site.

▪ Seismic resistance is heavily dependent upon adequacy of

connections which depend heavily on quality of

workmanship.

▪ The system is generally considered inadequate for

seismic regions.

85

86

Devastation in the Earthquake Affected Areas

Housing for ERRP

▪ Prime objective was to construct “Earthquake Resistant House”

▪ Owner driven construction approach was adopted

▪ Around 600,000 housing units were damaged and reconstructed

▪ Cash grant of Rs. 175,000/-

▪ Technical guidelines were provided with various types of available

construction materials.

▪ Stage wise construction supervision for release of financial assistance

▪ Conventional construction with seismic provisions

▪ Locally construction techniques like “Timber”, “Dhajji” and “Bahatar” were

also adopted

▪ Awareness program for the locals and work force

▪ Compliance catalogue for non compliant construction
