PROCEDURE FOR RECEIVING AND RECORDING OF CONSTRUCTION MATERIALS AT SITE
Delivery challans, while receiving any material, should specify the time and the receipt date. They should also carry the stamp of the site with the watchman’s signature.
PROCEDURE FOR RECEIVING MATERIAL AT SITE AND RECORDING OF MATERIALS
This procedure is described in the chart.
While receiving the material, the following steps will help avoid any mistakes in recording, quantity checking, and quality checking.
- The security personnel should complete the preliminary inquiries when material transport like tempo/truck/auto arrives at the entrance gate.
- The material should then be checked for quantity, measurement of material. type. quality, make, damages, defects, duplication, etc. and any anomalies should be mentioned on challan.
- If the quality does not match the specifications, the material should be rejected without unloading it (truckload) on site.
- If any material, other than the building material, differs from the specifications on the challan. it should be noted on the delivery challan The supplier should also be informed of it.
- The material should be unloaded to avoid any hindrance to activities like stock checking/issuing of material.
- If required, site engineers should help in stacking the material at the proper place.
- The storekeeper should inform the respective site engineer and project engineer after receiving the material.
- The project address on the challan should be checked. Any doubts about quantity should be communicated to the storekeeper.
- The storekeeper should check the documents, confirm the validity of supply with the engineer, and decide on the location for unloading.
- A sample checking for quality should be done at this stage with help from the engineer.
If the engineer cannot verily the supply/quality, he should inform the project engineer of the details regarding the supply/quantity of material.
After confirming that the material is required at the site and the supply is being done through proper channels, permission is given for the vehicle to enter.
- The watchman will note down the entry time and the details regarding the supplier, material quantity, etc. in his notebook.
- Unloading will be done at the location (e.g near working place/inside material godown/near store) indicated by the storekeeper.
- The storekeeper will supervise the unloading operation.
- If the material is found to be defective or of bad quality, after unloading, it will be referred to as the concerned driver.
- Measurements of truck/material will be taken in the presence of the driver.
- The driver will be informed of any comments to be written on the challan and his consent signature will be taken on both the copies.
- Complete information about the material, quantity received, disparities of measurement, material to be returned, etc. should be noted clearly on the challan. The storekeeper should seal it with the project stamp and his signature.
- He should also prepare the gate pass in duplicate.
- The gate pass is the permission for the truck to leave the site premises. Details of any material going out should be mentioned on the gate pass along with the exit time.
The watchman should sign and stamp the duplicate challan copy. He should also check the gate pass for the contents in the outgoing vehicle. Only then the vehicle is permitted to go out.
In case the material is to be rejected, the storekeeper informs the project in-charge of it. He, in turn, will intimate the purchasing department, and a decision to be reached after discussions.
BUILDING CONSTRUCTION MATERIAL STACKING AND PRECAUTIONS
- The storekeeper should take precautions while stacking all materials. General norms followed are listed below –
- The site engineer should be informed immediately of the receipt of materials, to finalize the stacking location.
- The material should be stacked nearest to their immediate required place.
- It should be stacked so that the material received first, is utilized first.
- All materials should be stacked in locked godowns. In case this is not possible, then at least M.S. chains should be tied for securing the items kept in open spaces/parking, etc.
- The security guards should be informed of any such items to ensure that daily counting and checking are observed.
- Fragile and expensive items like plumbing fittings and sanitary ware should be utilized immediately. The stacking period should be minimum. Unnecessary handling should be avoided.
- Since building materials get affected by water, necessary precautions should be taken to avoid dampness at places of storage.
- Up-to-date records of the stock must be maintained on a daily basis. A minimum level of stock should be maintained for each item and should be stacked at convenient locations.
- In case Interoffice Correspondence (I.O.C.) is received for the transfer of material to other sites, it should be easily located.
- The storekeeper should also check the collection/ accumulation of scrap material periodically. It should be stacked properly.
- The project in-charge should inform the purchasing department to arrange for the disposal of this scrap (e.g. empty cement bags, steel scrap, etc.).
I.O.C. OF MATERIAL RECEIPT TRANSFER TO OTHER SITES
- The storekeeper should exercise caution while handling an I.O.C. When the purchase department issues an I.O.C. for collection of material from the site, a Jr. Engineer Supervisor from other sites approaches with the I.O.C. to collect the material. In this situation, the following precautions should be taken.
- All transfers of material should be assigned to a Junior Engineer/Supervisor. Labour should not be deputed for these transactions.
- The storekeeper should check the quantities and specifications of the materials to be issued. The person accepting the material should also check all the details in the I.O.C.
- If the material referred to in the I.O.C. is not available on-site, the purchase department should be informed of the details of consumption of the material and hence the non-availability of the same.
- After the transfer as per the I.O.C., consumption entries of the material should be entered immediately and the records should be updated by the storekeeper.

- Aný balance material should be collected from the respective persons, making the requisite entries after the day’s work.
- The material should be issued exactly as per the instructions on the material issue slip.
- At the end of the day’s work, all materials issued a consumption chart.
- This chart should also indicate the day to day balance stock of each consumed material, after deduction of the day’s consumption.
- This chart is submitted to P.E by the storekeeper for further reporting to C.E, along with DPR.
DETAILED PROCEDURE FOR ISSUE OF CONSTRUCTION MATERIAL
The contractor his representative will demand the material required for the day’s work. This work is planned and discussed with the engineers the previses day or unpredicted alterations on that day.
The Engineer will issue the material issue slip to the contractor/representative.
- The writing should be legible and neat.
- It should indicate the location of the work and the work details.
- The material will be consumed should be clearly mentioned.
- Quantity of material required.
- Description of material with details of type, class, etc. should be mentioned.
- The engineer should sign the issue slip.
|Detail procedure of issue of material|
All materials should be issued strictly under the supervision of the storekeeper.
- The material should be checked before the issue.
- Material that is received first should be issued first.
- Quantity of material should be exactly as shown on the issue slip.
- The contractor/representative should sign the issue slip as acceptance of the material.
- All material issued should be recorded immediately non-consumable materials register.
After the day’s work, the balance material, if any, ould be returned to the stores.
- The storekeeper should visit the workplace during work hours, to see that there is no wastage.
- The entry of any returned material should be made immediately in the consumable/non- consumable register and actual consumption should be noted.
- The contractor representative should sign this register.
The engineer will take the measurements of the work done on the previous day. Reconciliation will be done and the storekeeper’s recording will be cross-checked.
The storekeeper will make entries on the daily material consumption chart, along with the balance stock of consumable items for that particular day.
The engineer will cross-check all consumption recorded and submit the daily material consumption report to the project engineer.
After checking the entries, the project engineer will submit his report along with other daily reports to the chief engineer.
CONTROL POINTS FOR ISSUE OF CONSTRUCTION MATERIAL
The contractor’s work should be carried out as per the instructions and planning of the site engineer. If it is observed that the contractor is not working as specified, the issue of materials can be delayed or stopped. This decision should be taken for the following reasons –
BY BUILDING SITE ENGINEER
- If the contractor does not clean the previous day’s work properly.
- If he delays curing or makes improper arrangement for curing.
- If manpower for repairs of the faulty works Is not arranged on a priority basis.
- If he diverts his labourers to some work other than specified, then the material issue can be stope.
BY BUILDING CONSTRUCTION STOREKEEPER
- If the contractor is wasting the material.
- If he does not return balance material or empty bags, electric focus, lighting wires, etc.
- If he does not stack the scrap steel in the godown properly.
- If he does not return wooden planks, M.S. ghodies, scaffolding material after completion of the work.
- If he does not co-operate in signing memo notes raised against his name.
PERIODICAL STOCK CHECKING
The storekeeper should cheek the actual physical stock twice a month, For this, he may ask for the site engineer’s help. The stock recorded, should be counter-signed by the project engineer. Any discrepancies found should be communicated to the head office immediately.
Materials should be stored separately for minimizing the time required for stock checking under the following categories.
- Sanitary ware
- The storekeeper should clean and rearrange the store periodically. Labeling of Items should be done. Entry in the store during such works should be restricted to the site staff.
- The godowns should be locked and sealed with paper, signed by the watchman and the storekeeper together with the due date, time, and the site stamp every day.
- It should be unlocked on the next working, day, the presence of the storekeeper, engineer, and the watchman on duty.
- The storekeeper should prepare daily material Consumption reports for all consumable he materials and record them in the register daily.
- But materials which are not issued directly by the storekeeper,e, steel, sand, metal, gt, dust, etc, daily consumption report is not possible.
- In this case, the concerned engineer should prepare the consumption statement and give it to the storekeeper on every 14th and 29th of the month for preparing the fortnightly report.
- For timely feedback of material consumption and reconciliation, the engineer should submit the reports in time, The project engineer should deal strictly in this matter, He should instruct the storekeeper to collect the reports from the concerned engineer in time.
- If the considerable difference in actual stock and recorded stock is observed by the project head, then all the recording should be corrected as per actual stock after thorough checking and verification.
- Also, a written explanation should be submitted by the project head, detailing all the corrected entries in the record.
Keeping the stores updated is very important. Not only storekeepers but the site engineer should also participate actively and effectively in the storekeeping activity. The engineers should also attend to other systems on the site like the safety of temporary electrical wiring, cleaning, wastage control, etc.
The Project Engineer should allot duties in rotation to every engineer, for checking the store daily, as per the given format.
