Regulatory Requirements [6 Hours]

11.1 Safety Requirements 20812080207920782075207320712070

Why Regulatory Requirements are Needed in Construction 2080 2073

Regulatory requirements are essential in any construction project for the following reasons:

1. Worker safety & health: Construction is one of the most hazardous industries. Regulations ensure minimum safety standards, PPE usage, and safe working procedures to protect workers from injury and death.
2. Public safety: Construction activities affect the surrounding public. Regulations ensure that structures are safe for occupants and that construction processes do not endanger nearby people or properties.
3. Quality assurance: Building codes and standards ensure that materials, workmanship, and design meet minimum quality requirements, preventing structural failures.
4. Environmental protection: Regulations control pollution, waste management, noise, and dust emissions from construction sites, protecting the environment and surrounding communities.
5. Legal liability & accountability: Regulations establish clear responsibilities for employers, contractors, and workers. Violations lead to legal penalties, ensuring accountability.
6. Compensation & insurance: Regulatory frameworks mandate insurance coverage and compensation for workers injured on the job, providing financial protection.
7. Uniform standards: Regulations provide uniform standards for construction practices across the country, ensuring consistency in quality and safety.
8. Dispute resolution: Regulations provide a legal framework for resolving disputes between parties involved in construction projects.

In Nepal, key regulatory instruments include the Labor Act 2074, Environment Protection Act 1997, National Building Code (NBC), Building Act 2055, and related building bye-laws.

What is an Accident?

An accident is an unplanned and unexpected occurrence which upsets the planned sequence of events and actions, resulting in the loss of production, injury to the person, and damage to plants and equipment.

Causes of Accidents 2081 2078 2071

In the construction industry, there are many causes of accidents. Broadly, the causes may be classified as follows:

Physical Causes — Relating to Machines

• Working space for machines may be inadequate
• Obstruction-free movement of man and material is not possible
• Machines not being properly placed or adjusted
• Unsuitable machines not being properly guarded

Physical Causes — Relating to Tools

• Due to constant use, tools being blunt
• Tools employed on the job too small
• Tools used may be of brittle nature (e.g., blades of a circular saw)
• Handle of tool may be too short or loose
• Tools used may be unsuitable for the job

Physical Causes — Relating to Materials

• Materials used may be poisonous and dangerous (acids, salts, etc.)
• Material may be too hot (tar or bitumen in road construction) with no proper precautions taken
• Explosives, petroleum products, and chemicals being handled carelessly
• Not adopting proper precautions while working with materials that emit foul gases

Physical Causes — Relating to Uniform

• Uniform may be loose
• Shoes may be slippery and loose
• No protective device being used (e.g., while welding)
• Sleeves of a shirt being without buttons

Physical Causes — Relating to Environment

• Poor lighting arrangement at site of work
• Poor ventilation and unhygienic conditions
• Non-insulated wires left carelessly
• Loose electric cables
• Obstacles in the working area
• Floor being slippery
• Scaffolding used being unsafe
• Use of unsuitable (weak or short) ladders
• External disturbances like noise
• Loose discipline among workers

Objectives of Accident Prevention

• Saving human life
• Prevention of temporary and permanent injury
• Prevention of damages to plants and equipment
• Saving in the cost of compensation to workers
• Saving in loss of time due to injury

Classification of Accidents

1. According to cause of occurrence
2. According to nature of injury:
   • Temporary disablement
   • Partial disablement
   • Total disablement
   • Death
3. According to severity of injury:
   • Minor accident
   • Major accident
   • Accident hazard

Safety Requirement

Many safety standards use the concept of a safety requirement to ensure that the system carries out the functions needed to make it acceptably safe. A safety requirement has two components:

1. Safety functions requirement: Details how the system should avoid the occurrence of a hazard
2. Safety integrity requirement: Details how often the function can fail and allow the hazard to occur

Why Safety is Important in Construction? 2079 2078 2075

In Nepal, the construction industry is labor-intensive and has the largest labor force after agriculture. The cost of an accident is very expensive.

1. Humanitarian reasons: The sufferings and distress of the injured worker and family members are difficult to quantify in economic terms
2. Economic reasons: Accidents have direct and indirect costs
   • Direct costs: Medical expenses, compensation amount, legal charges, cost of replacement of damaged material
   • Indirect costs: Slowdown in progress, productive time lost, decrease in productivity due to moral decrease, need to make up for lost time, loss of confidence, loss of administrative time
3. Organizational image: Good safety record enhances morals, loyalty, and public image of the organization
4. Laws and Regulations: The employer must adhere to regulations laid down by the Government for the safety of employees. Violation may lead to punishment

Factors Influencing Safety

During construction, safety is influenced by decisions taken during planning and design. Clear separation of traffic from construction zones can greatly reduce possibility of accidental collisions. Safety also depends on:

• Education and training of workers
• Vigilance and cooperation during construction
• Choice of proper technology and machines
• Proper choice of materials
• Educating managers and workers about proper procedures and hazards

Safety Measures in Construction Areas 2073

Safety measures are required in the following areas:

• Excavation
• Scaffolding, ladders, and formworks
• Hot bitumen work
• Demolition works
• Drilling and blasting works

Approach to Improve Safety

1. Organizational approach: Safety committee, development of safety system, incentives
2. Physical approach
3. Behavioral approach
4. Danger signs and signals
5. Caution signs and signals
6. Informative signs and signals

Lightning Arresters/Conductors

Many incidents in Nepal where lightning strikes have caused fire. Lightning arresters should be installed at the highest part of building, connected by conductor to an earth rod buried in the earth.

Insurance 2079 2070

Insurance is primarily used to hedge against the risk of uncertain, contingent loss. The insured assumes a known relatively small loss (premium) in exchange for the insurer's promise to compensate in case of financial loss.

Characteristics of Insurable Risks

• Large number of similar exposure units: Benefits from the law of large numbers
• Definite loss: Loss at known time, place, and cause
• Accidental loss: Fortuitous, outside control of beneficiary
• Large loss: Meaningful from perspective of insured
• Affordable premium: Likelihood and cost proportionate
• Calculable loss: Probability estimable and cost assessable
• Limited catastrophic risk: Losses ideally independent and non-catastrophic

Types of Insurance

• Health insurance: Covers cost of medical treatment
• Accident, sickness, and unemployment insurance: Financial support when unable to work
• Short-term disability: Covers up to six months
• Long-term disability: Covers until permanently disabled
• Total permanent disability insurance: Benefits when permanently disabled
• Workers' compensation insurance: Replaces wages and medical expenses for job-related injury
• Property insurance: Protection against fire, theft, weather damage

Methods of Insurance

• Co-insurance: Risks shared between insurer and insured
• Dual insurance: Same risk covered by two policies
• Self-insurance: Individuals themselves bear the risk
• Reinsurance: Insurer passes some/all risks to another insurer (reinsurer)

Construction Works Insurance (Contractor's All Risk — CAR)

CAR Policy provides an "All Risks" cover. Any hazard not specifically excluded is covered. It covers sudden and unforeseen loss or damage from the starting date until the Defects Liability Period.

Contractor's risks covered:

• Loss of or damage to Works, Plant, and Materials
• Loss of or damage to Equipment
• Loss of or damage to property in connection with the Contract
• Personal injury or death

CAR Policy perils covered:

• Fire and Lightning
• Accidental damage during construction (falling, defective workmanship, negligence, malicious act, human error)
• Water damage, Flood, Storm, Tempest, Earthquake
• Collapse, Collision, Impact
• Theft & Burglary, Malicious Damage
• Subsidence, Landslide, Rockslide

Fire Insurance

Governed by Nepal fire policy. To constitute fire under fire policy, three features required:

1. There should be actual ignition
2. It should be fortuitous/accidental in nature
3. The property destroyed or damaged must be insured

Standard fire insurance policy covers: Fire and Lightning, Explosion, Flood and Inundation, Storm/Cyclone/Hurricane, Strike/Malicious damage, Subsidence and Landslides, Earthquake fire and shock, Aircraft damage, etc.

11.4 Environmental Concern & Protection 2071

Environmental Law

Environmental law encompasses those rules, norms, values, and laws that relate primarily to the protection of the whole environment — air, water, and land against pollution, the protection of ecosystems together with public information, remedies, and procedures.

Environmental law, in its broadest sense, is an instrument for achieving sustainability. It requires standards, gives permanence to policies, and is based on scientific understanding and clear analysis. These laws set rules for human conduct and lead to communities living within the limits of the earth.

Major Features of Environmental Law

• Often framework acts requiring detailed regulations to be made effective
• Commencement is often delayed or staggered
• Include unclear definitions to preserve flexibility in application
• Confer wide discretions in areas like protection, setting standards (e.g., amount of pollutant discharged), and enforcement

International Environmental Law

Key international agreements include: Stockholm Declaration 1972, Rio Declaration 1992, Kyoto Protocol 1997, and Paris Agreement 2015. Key principles: Precautionary Principle, Polluter Pays Principle, Principle of EIA, and Sustainable Development.

Implementation Status in Nepal

Nepal, being a member of UN, SAARC, SACEP, and ICIMOD, has played a significant role in the field of environment. Nepal participated in the UN Conference for Environment (UNCHE) at Stockholm and the Earth Summit in June 1992.

Environment Protection Act 1997 (Nepal)

Enacted to maintain clean and healthy environment, minimize adverse impacts, and achieve sustainable development through proper use and management of natural resources.

Salient Features

• Defines 'Environment', 'IEE' (Initial Environmental Examination), and 'EIA' (Environmental Impact Assessment) — which must be submitted before implementing any development proposal
• Section 3, 4, 5, 6: Contain provisions on IEE, EIA, and procedures for getting approval
• Section 7: Prevention and control of pollution
• Section 8: Appointment of 'Environment Inspector'
• Section 9: Protection of national heritage
• Section 10: Authorizes GoN to declare Environment Protection Areas for areas containing aesthetic/rare wildlife, biological diversity, or places of historical/cultural importance
• Provision for establishment of 'Environment Protection Fund'
• Provision of compensation to victims of pollution
• Empowers Ministry to prohibit any material, fuel, equipment, or plant having adverse effects on environment

Shortcomings of the Act

• Has not recognized public participation effectively in EIA and IEE processes
• EIA guideline should be mandatory under Section 23
• Prevention and control of pollution provisions are almost dead in practice
• No appointment of Environment Inspectors till date
• No separate section for biodiversity conservation
• Laboratories not established
• No 'Environment Protection Fund' to date
• Punishment provisions should be reviewed and limits fixed scientifically

11.5 Building Codes & Quality Control 208120802079207720752074207320722070

National Building Code (NBC) 2081 2079

A building code, or building control, is a set of rules that specify the standards for constructed objects such as buildings and nonbuilding structures. The main purpose is to protect public health, safety, and general welfare as they relate to the construction and occupancy of buildings and structures.

Building codes are generally intended for architects, engineers, constructors, and regulators but used by safety inspectors, environmental scientists, real estate developers, subcontractors, facility managers, tenants, insurance companies, and others.

NBC Background in Nepal

Most of the buildings in Nepal are highly vulnerable to earthquakes. The 1988 earthquake in eastern Nepal resulted in more than 600 deaths and 20,000 buildings collapsed or damaged, including school buildings.

As a result, the government ultimately developed the National Building Code (NBC) which provides both regulations and guidelines for design of buildings in all areas of Nepal. Nepal lies in a high seismic zone, and NBC plays a significant role in earthquake-resistant design of buildings.

Although NBC came into existence in 1994, it was approved by the government only in 2003.

Four Levels of NBC 2079

Part I: International State of the Art

NBC 000 — Applicable to modern and sophisticated buildings such as BICC, constructed considering building codes of developed countries.

Part II: Professionally Engineered Buildings

Standard code requirements for professionally qualified engineers. Covers structures such as hospitals, meeting halls, factories, warehouses, multistoried buildings, and residential buildings where:

• Plinth area > 1000 sq. feet
• Story > 3 numbers
• Structural span > 4.5 meters

Related codes: NBC 101 to 114 and NBC 206 to 208.

Part III: Mandatory Rules of Thumb

For buildings not requiring professional engineer design (plinth area ≤ 1000 sq. ft, stories ≤ 3, span ≤ 4.5 m). Can be designed by trained level technicians.

• NBC 201: RC Buildings with Masonry Infill
• NBC 205: RC Buildings without Masonry Infill
• NBC 202: Load Bearing Masonry

Part IV: Guidelines for Remote Rural Buildings

Address typical building styles identified from approximately 40 intensive surveys. Emphasize changes to improve seismic resistance. Normally earthen construction (unfired masonry, mud mortar, rubble, dry stone).

• NBC 203: Earthquake Resistance Construction — LSM
• NBC 204: Earthquake Resistance Construction — Earthen Buildings

Building Permit Application Forms

• NBC 206: Architectural Design Requirement
• NBC 000:1994 to NBC 114:1994 — Structural Design Requirement
• NBC 207:2003 — Electrical Design Requirement
• NBC 208:1994 — Sanitary and Plumbing Design Requirement

NBC Significance

• Maintaining uniformity for materials and techniques
• Focusing on earthquake-resistant design
• Emphasizing use of spaces with proper guidelines
• Guiding engineers, sub-engineers
• Flowing information and standards for electrical and sanitary designs
• Serving as basic document to verify designs submitted for approval

How Building Codes Help in Effective Urban Planning 2080 2079 2075 2073

Building codes and bye-laws play a crucial role in effective urban planning in the following ways:

1. Controlled & planned development: Building codes regulate setbacks, Floor Area Ratio (FAR), Ground Coverage Ratio (GCR), and building heights, preventing haphazard and unplanned construction that leads to congested urban areas.
2. Land use regulation: Codes help classify areas into residential, commercial, industrial, and mixed-use zones, ensuring compatible land uses and preventing conflicts (e.g., factories next to schools).
3. Public safety & disaster resilience: Codes mandate earthquake-resistant design, fire safety provisions, and structural standards, making urban areas safer and more resilient to natural disasters — especially important for Nepal which lies in a high seismic zone.
4. Infrastructure adequacy: Building codes ensure adequate road widths (Right of Way), open spaces, parking provisions, and access for emergency vehicles, supporting efficient urban infrastructure.
5. Environmental sustainability: Codes regulate drainage, sanitation, ventilation, lighting, and waste management, promoting healthy and sustainable urban environments.
6. Preservation of heritage & aesthetics: Building bye-laws include guidelines for cultural heritage zones, maintaining the character and aesthetic quality of historically significant urban areas.
7. Uniform standards: Codes establish uniform quality standards for construction materials, techniques, and structural design across the country, ensuring consistency in the built environment.
8. Population density management: By regulating FAR, GCR, building height, and plot sizes, codes help manage population density and prevent overcrowding in urban areas.
9. Provision of public facilities: Planning bylaws mandate allocation of open spaces, public facilities, and community infrastructure within developments.

In Nepal, despite having NBC since 1994 (approved 2003), effective implementation remains a challenge. Stronger enforcement of building codes can significantly improve urban planning outcomes, reduce earthquake vulnerability, and create safer, more livable cities.

Challenge: Construction as per the spirit of the code is not happening due to resource lack, lack of effective coordination and evaluation mechanisms.

Building Bye-Laws 2077

It is mandatory to have building permission from Town Development Office, Metro/sub-Metro, Municipalities, and VDCs. Building bye-laws are prepared to ensure public health and safety, planned development, and planned built environment.

Building Bye-Laws cover:

• Right of Way (ROW)
• Set back
• Floor Area Ratio (FAR)
• Ground Coverage Ratio (GCR)
• Height of the Building
• Guidelines for Cultural Heritage Zone
• Clearance required from important sites

Planning Bylaws: Deal with elements like land use, size of plot, area and its depth-width ratio, length of cul-de-sac, area of open space, public facility requirements.

Key Housing-Related Legislations

Building Act 2055, Town Development Act 2045, Apartment Act 2054, National Building Code Implementation Procedures 2060, Building Regulations 2062, and National Shelter Policy 2053.

Quality Control (QC) 2073 2072

Quality Control is a process by which entities review the quality of all factors involved in production. This approach places emphasis on three aspects:

1. Elements: Controls, job management, defined and well-managed processes, performance and integrity criteria, identification of records
2. Competence: Knowledge, skills, experience, qualifications
3. Soft Elements: Personnel integrity, confidence, motivation, team spirit, and quality relationships

Quality involves single product inspection, where every product is examined before delivery to the external market, using inspection for fine details to detect surface blemishes and other defects.

Important Things to Consider
