Survey, Design, and Construction Supervision
(Resident) Services in Karachi, Pakistan

Work Station: Karachi, Pakistan
Expected Start Date: 1 May 2026
1. Background / Rationale:
The United Nations Human Settlements Programme (UN-Habitat) is the United Nations agency
mandated by the General Assembly to promote socially and environmentally sustainable towns and
cities with the goal of ensuring adequate shelter for all. In Pakistan, UN-Habitat works in
partnership with national and provincial governments, development partners, civil society
organizations, and academic institutions to support inclusive urban development and improved
living conditions in underserved settlements.
UN-Habitat Pakistan is currently implementing a participatory settlement upgrading programme in
several cities, including Haripur, Kohat, Peshawar, Karachi, and Quetta. In Karachi, the programme
targets 12 underserved settlements where Community Action Planning (CAP) processes are being
conducted to identify priority needs and feasible interventions. The programme combines social
programming with targeted infrastructure improvements, including public space upgrades,
improved connectivity, and the construction and rehabilitation of small-scale infrastructure. These
interventions aim to enhance living conditions by improving access, water supply, sanitation and
sewerage services, and other essential community infrastructure.
Karachi, Pakistan’s largest metropolitan city, faces complex urban challenges including high
population density, heavy traffic volumes, monsoon-driven drainage issues, and coastal
environmental conditions. Within this framework, the project also includes improvements to smallscale
urban infrastructure to enhance accessibility and safety. The present procurement is covers
the design and construction supervision of two Steel Bridges Near Lassi Goth (10ft wide – 260ft
long for light vehicular bridge) and Hassan Noman, (4ft wide – 230ft long pedestrian bridge)

2. Objectives of the Assignment:
The objective of this assignment is to procure the services of a qualified consulting firm to
undertake the engineering design and construction supervision of two bridges in Karachi. The
consulting firm will conduct the necessary site surveys, soil investigations, hydrological
assessments, and traffic load analyses required for safe, reliable, and economical bridge design.
Based on these investigations, the consultant will prepare complete engineering design packages
including detailed drawings, structural calculations, technical specifications, Bills of Quantities
(BOQs), and engineer’s cost estimates to support procurement and construction.
The firm will also support UN-Habitat in obtaining necessary approvals and No Objection
Certificates (NOCs) and also provide technical clarifications during the procurement process (if
required). The consultant firm will prepare all required engineering calculations and documentation
to facilitate third-party design validation or review by the relevant government authorities.
During the construction phase, the consulting firm will act and provide Engineering services on
behalf of UN-Habitat, for the works and provide full construction supervision to ensure that the
works are implemented in accordance with the approved designs, technical specifications,
environmental and social safeguards, and applicable safety standards.
The consultant will establish and implement a comprehensive Quality Assurance and Quality
Control (QA/QC) system, including supervision of construction activities, review of contractor
method statements, verification of contractor performance, certification of work progress, and
monitoring compliance with contract specifications and engineering standards. Material testing
required for quality control will be carried out by the contractor through approved laboratories,
while the consultant will review testing procedures and results, watch critical tests where necessary,
maintain testing records, and ensure that only quality materials are used in the works.
In addition, the consultant firm will provide contract administration services, including the review
of contractor submissions, review and recommendation of interim payment certificates for UNHabitat
approval, evaluation of variations, and monitoring of construction progress against the
approved schedule. The consultant firm will remain engaged until completion of the bridges and
issuance of the Substantial Completion Certificate to the contractor.
During the construction stage, UN-Habitat (including third-party monitoring entity) will undertake
routine monitoring of the works and oversee the certification of payments, management of
variations. UN-Habitat directly or through Third party monitoring, will be responsible for handover
process and will monitor the project during the Defects Liability Period (DLP) and coordinate with
the contractor to ensure that any defects identified during this period are properly addressed. Below
is the bridges information.
Bridge-1: Light vehicular Steel bridge 260 ft long X10 ft wide at Lassi Goth-Karachi
Bridge-2: Pedestrian Steel bridge 230ft long x 4 ft wide at Hassan Noman-Karachi

The consulting firm will provide all professional services necessary for the soil investigation,
design, documentation, and technical support during the construction of two bridges in Karachi.
The investigations and studies undertaken for design purposes will be limited to those reasonably
required to support a safe, reliable, and economical bridge design, and will be proportionate to the
scale and complexity of the works. The assignment includes geotechnical investigations,
determination of High Flood Level (HFL), estimation of scour depth, detailed engineering design,
preparation of construction documents, and technical supervision during construction. The scope
includes the below but not limited to;
3.1. Site Surveys and Investigations: The consultant firm will undertake all necessary surveys
and investigations required for the proper design of the bridges, which include:
a. Topographic surveys of the proposed locations for both bridges, including surrounding terrain,
approaches, drainage paths, and existing infrastructure
b. Carry out geotechnical investigations and soil testing at both bridge locations to determine soil
characteristics, bearing capacity, groundwater conditions, and other parameters required for
foundation design and prepare report.
c. Determine the appropriate design load classification for the bridge based on analysis of current
and projected traffic volumes and composition, covering cars, pedestrians, bicyclists, and other
vehicles.
d. Collect and review relevant site data, existing infrastructure information, and environmental
conditions.
3.2. Concept Design: Prepare concept design options and layout drawings for both bridges
including footpaths, service ducts, accessibility elements and finalize the concept in consultation
with UN-Habitat. Explore the possibility of introducing guiding tiles for visually impaired
persons, and the use of Sindh motifs to enhance the visual identity of the bridges.
3.3. Structural Design: prepare complete structural designs for the bridges and associated
structures, ie. Foundation/ sub-structure, super-structures/abutments, deck, railing, approach road,
protection work if needed.
The firm will submit the design for review and endorsement by a third-party validator or relevant
government department, as recommended by UN-Habitat.
3.4. Engineering documents: prepare complete construction documentation for bidding and
