Note the difference in rolling circumference:

Rolling circumferences are generally approved in the range +1.5% und -2.5% g. Please check with the responsible inspector beforehand.

Speed deviation outside the norm:

In EU countries, the speedometer may display a maximum of +10 % + 4 km/h and no km/h less than the actual speed driven.

3 Fixed | Kerala Pwd Price

The rates are not static; they are periodically updated by the government to reflect market fluctuations.

The Kerala PWD Rate/Price 3 consists of several components, including:

: The system automatically generates Bill of Quantities (BOQ) and tender schedules for the e-tendering process. 2. The Role of Schedule of Rates (SoR) The "Price" in PRICE 3.0 is governed by the Delhi Schedule of Rates (DSR)

To get the most current and precise rate for any SOR item, you should check the official channels directly. The PWD publishes the SOR, but it may not be easily accessible online. For the most accurate information, it is best to:

| Component | % of Price 3 | Source | | :--- | :--- | :--- | | | 55% | Quoted from district-level dealers (Price 1) | | Labour & Shuttering | 25% | PWD standard labour schedules | | Plant & Machinery (Mixer, Vibrator) | 10% | Depreciation + fuel (linked to diesel price index) | | Overheads (Site office, security, water) | 5% | Fixed | | Contractor’s Profit | 5% | This is the key number. In Price 3, profit is legally capped at 5%. | kerala pwd price 3

The system has progressed significantly from its early iterations to its current advanced version, (commonly referenced as Kerala PWD PRICE 3 ). This software provides a unified web-based application covering the entire lifecycle of public works across multiple engineering organizations in Kerala. What is the PRICE 3.0 Software Ecosystem?

The PRICE3_PMU_Demo_Presentation outlines that the system is overseen by the PRICE Project Management Unit (PMU), which includes executive and coordination committees to ensure smooth operations.

The PRICE 3.0 system is robust, featuring several modules designed to streamline construction projects:

⚠️ These rates are revised annually or biennially. Always refer to the latest SoR (e.g., 2023–24 or 2024–25). The rates are not static; they are periodically

The Schedule of Rates (SoR) is the official rate book of the Kerala PWD. It is the foundation of all cost estimates for government civil works, including buildings, roads, and bridges. The SoR provides standard unit rates for thousands of construction items and is updated periodically to reflect market conditions.

Supports the entire approval chain, from online estimate submission by Assistant Engineers to digital issuing of Administrative Sanction (AS) and Technical Sanction (TS) .

Creating, reviewing, and approving detailed estimates and recast estimates. Tender Management: Online handling of tender processes.

Based on the standard terminology used by the Kerala Public Works Department (PWD), "Price 3" refers to a specific set of rates used for calculating contract amounts. The Role of Schedule of Rates (SoR) The "Price" in PRICE 3

Tire diameter
Tire diameter:
Diameter of the tire.
Rolling circumference
Calculation incl. load from the vehicle and at a speed of approx. 60 km/h (40 mph) (tire circumference * 0.97).
Tire circumference
Purely calculated circumference of the tire without mounting on a rim and without load.
Tire height
Height of the sidewall of the tire.
Rim size
Rim size:
Diameter of the rim.
Rim width
Rim width:
Width of the rim.
Poke (Outer Edge)
Distance between the OUTER rim edge and the contact surface of the brake disk or brake drum.
Inset (Inner Edge)
Distance between the INNER rim edge and the contact surface of the brake disk or brake drum.
Change in ground clearance
Value by which the vehicle is higher or lower with the new tires.
Changing the rolling circumference. If the deviation is too high, it may be necessary to adjust the speedometer.
Displayed speedometer value with desired tires, which corresponds to the displayed 100 mph or km/h with existing tires.
Change outer edge per side
Distance between the outer surfaces of the rims. The rims in the wheel housing move inwards or outwards by this value.
Change inside edge per side
Distance between the inner surfaces of the rims. The ET (offset) has an influence on this value.
