Resource Planning

Project: The Park - Lodha

Prepared By: Karan Tibdewal (UC1510)Guided By: Prof. Reshma Shah

Scope of Resource Planning

• Materials• Equipment• Labor• Professionals – Skilled Set of People

Stages of Resource Planning

• Conceiving Stage• Development Stage• Implementation Stage• Commissioning Stage

Resource Planning – Conceiving Stage

• Bidding Weightage - 18% of Technical Feasibility Score

• Major Constraints Identified– Delivery and Storage of Materials

Resource Planning – Development Stage

• Property and applicable IS Codes of various materials required is established

• Soil Investigation Report• Quantity of Base Rate

Materials Established after Value Engineering

• Material Contracts given out.

• Requirement of onsite batching plant is established with quantity and rate of production.

• Job Layouts for all the phases are prepared

Soil Investigation Report

• Purpose of the report in Resource context

• Geotechnical investigation consisted of twenty six boreholes.

• M/s Ochre Drillers India Pvt Ltd carried out fieldwork of twenty two boreholes from December 03, 2012 to January 23, 2013.

• Geotechnical investigation was planned to obtain subsoil stratification in proposed project area and collect soil, rock and ground water samples for laboratory testing to determine engineering.

a) IS-1892 : Code of practice for Subsurface Investigation of Foundations.b) IS-1498 : Classification and Identification of soils for General Engineering Purposes. c) IS-2131 : Method for Standard Penetration Test for Soilsd) IS-2132 : Code for practice for Thin Walled Tube Sampling of Soils.e) IS-5313 : Guide for Core Drilling Observations.

Soil Investigation Report - Results• Study indicates that at expected founding level, highly & moderately weathered Tuff is present in ten boreholes and slightly weathered Tuff is present in remaining boreholes. Slightly weathered Tuff is present in all boreholes within short excavation depth. Slightly weathered Tuff is suitable for placing foundations. It continues up to termination depth, improving in quality with depth. Therefore, it is recommended to placing foundations in slightly weathered Tuff stratum.

Based on the result of chemical analysis of water, water is not aggressive to concrete but severely corrosive to reinforcement steel. Therefore, it is recommended: 1. Use Pozzolana Portland cement for all work till plinth beam2. Use minimum cement content of 350 kg/m3 of concrete with minimum grade of concrete M30.3. Adopt minimum clear cover of 75 mm to the reinforcement steel.4. Provide approved anti corrosive treatment to reinforcement steel

Challenges Identified

• Constraint of Time and Space• Availability of Resources• Not relying on single source to minimize risks

(Number of Contractors and packages: 2-5)• Direct Sourcing from Manufacturers– Volume

Dependency

Concrete (RMC)Two on-site Concrete Supply Contractor (CSC) 1) M/s. ACC Concrete Limited (at Mumbai Textile Mills Plot) and 2) M/s Lafarge Aggregates & Concrete Pvt. Ltd. (at Sreeniwas Mills plot adjacent to the Mumbai Textile Mills Plot)

in addition to 3) Backup plants offsite to act as a preferred vendor for supplying concrete to the project. As a preferred vendor,

the rates offered by the CSC will be treated as a benchmark rate for computing the difference in basic rate and the actual rate of the relevant items in the BOQ.

Payable Rate for RMC = 1.015*Variation in Basic Rate

Basic Rate of Materials

Example – Steel Procurement

Resource Planning – Estimating Requirements (Concrete)

Assumptions in Estimation

• CSC will supply concrete as per contractor’s requirement subject to: • For mass concreting, the maximum requirement should not exceed 1000

cum per day with consideration of supply for 20 hrs per day from captive plan. Additional quantities can be arranged from back up plants and commercial plants.

• Minimum quantity requirement should not be less than 3 cum for any single order at any given point of time.

• Supply of concrete from the captive plant located at site will not be available for a maximum of 2 days per month due to possible maintenance activities in the plant. These 2 days will be decided by the CSC in consultation with the Contractor. CSC will arrange the supply of Concrete upto grade M60 in this period from their nearby outside plant.

• Basic Assumption: 6 towers of 78 floors each, 6 level podium, 6 villas, retail outlet, GCP to be constructed over a period of 72 months (6 years). In addition they have considered 30% of the balance volume requirement of Shreeniwas mills for which project RMC plant can act as a backup.

RMC Estimation and Conclusion – Backward Integration

Therefore, project

would need one

dedicated RMC plant of

capacity 120 cum /

hour (running in two

shifts) to cater to peak

volumes of 25,000 cum

per month and average

requirement of 10,000

cum per month

Responsibilities of Material Management

• Receipt of materials and proper storage• Checking quantity of material received • Issue of material to site as per PO • Removal of rejected material from site• Physical check of stock at site • Disposal of expired material from site• Inventory control at site• Inter site material transfer

Resource Planning - Implementation

• Finalizing of the equipment and resources

• Stocks are maintained based on estimation

• Stores are required to update, generate inquiries according to requirements

• Based on stocks used and estimated S- Curve for Resources are plotted

Resources - Layout

Labor Colony Requirements and Clauses

• Lodha will provide space and contractor will construct colony for labour accommodation.

• In case contract requires additional labor accommodation at site during contract period Employer will charge Rs.1000/- per labor per month extra to contractor.

• Beyond contractor period i.e. due to delay in completion for reason attributable to contractor Lodha shall charge labor accommodation at Rs.1000/- per labor per month to contractor.

Material Procurement

• Total material Cost: 70%• Codification of the

materials & ABC analysis: This analysis categorized the materials based on their impact on the total inventory cost

Lead-Time Analysis

The table shows the amount of the time required for the particular materials in terms of days according to above mentioned factorsThe time between the arise of need of the particular material and its availability on site is the LEAD TIME of that particular material.The factors to be considered for the calculation of the lead time are as follows: Intimation to material manager about the quantity of the material and time at which it is needed. Material manager’s decision to purchase that material. Selecting the source, fixing the price & ultimately placing the order. Supplier to deliver the material Transportation and receiving the material Inspection and testing of materials.

Billing

• A total Mobilization advance of 7.5% of the contract value (before tax) will be paid by the Employer against the Contractor furnishing to the Employer Bank Guarantee/s of equivalent value (7.5% of Contract Value (before tax) + Service tax) from Nationalized or approved Bank by Employer within 15 days of issue Letter of AwardThis mobilization advance will be recovered from the Contractor’s running account bill starting from the 1st R.A bill in equal installments of the advance value per monthly R.A bill. Entire advance value will be recovered in the 39 months bill period from the running R.A bill irrespective of the R.A. bill value / Contract duration extension (if any)

• An advance of 90% of material value will be payable for Steel brought by the Contractor and stored at site for the purpose of incorporation in the works for the subsequent 2 months. Contractor shall claim such advance along with the respective month’s running bill and shall do so for unconsumed quantities only. Recovery of such advance will be done through subsequent 2 months R.A. Bills. No separate advance will be payable for any other materials bought by the Contractor and stored at site for the purpose of incorporation in the works

• In case the Employer instructs the Contractor to purchase any Basic Rate Material in quantities that are in excess of that required for usage within two months from the date of such instruction, the Employer will release to the Contractor an amount equal to the value of the material as shown in the invoice for the material on receipt of such material at site within 30days of material receipt. Recovery of such advance shall be done on the basis of proportionate consumption of the material thus procured.
