QUANTITY ESTIMATION & MANAGEMENT (RCE-503)
B.Tech (SEM-V) – AKTU
SECTION A
(Attempt all questions – 2 × 7 = 14 marks)
Q1 (a) Define most likely time and mean time.
Most likely time is the time required to complete an activity under normal working conditions.
Mean time is the expected average time for completion of an activity and is calculated using optimistic, most likely, and pessimistic times in PERT analysis.
Q1 (b) Define Contract.
A contract is a legally binding agreement between two or more parties, in which one party agrees to execute work and the other agrees to pay for it under specified terms and conditions.
Q1 (c) Differentiate between free float and total float.
Free float is the amount of time an activity can be delayed without affecting the early start of the succeeding activity.
Total float is the maximum time an activity can be delayed without delaying the overall project completion time.
Q1 (d) Enlist the main items of work used in estimation of buildings.
Main items include earthwork, foundation concrete, brick masonry, RCC work, flooring, plastering, doors and windows, painting, and finishing works.
Q1 (e) What do you mean by critical path of a project network?
The critical path is the longest path in a project network which determines the minimum project completion time. Activities on the critical path have zero float.
Q1 (f) Differentiate between Event and Activity.
An event represents the start or completion of an activity and does not consume time.
An activity represents actual work carried out and consumes time and resources.
Q1 (g) What do you mean by Land Acquisition?
Land acquisition is the process by which government or authorized agencies acquire private land for public purposes such as roads, buildings, and infrastructure projects.
SECTION B
(Attempt any three – 7 × 3 = 21 marks)
Q2 (a) What are different types of construction contracts and state their main attributes?
Construction contracts include lump sum contracts, item rate contracts, percentage rate contracts, cost plus contracts, and turnkey contracts.
Each type differs in payment method, risk sharing, flexibility, and suitability depending on project size and nature.
Q2 (b) Explain briefly the importance of specifications in estimation and contract.
Specifications define quality, type of material, workmanship, and execution method. They ensure uniformity, avoid disputes, help in accurate estimation, and form a legal part of contract documents.
Q2 (c) Explain the objectives of project management in construction.
Project management aims to complete construction projects within time, cost, and quality constraints. It ensures proper planning, scheduling, coordination, cost control, and efficient utilization of resources.
SECTION C
(Attempt any one part from each question – 7 × 2 = 14 marks)
Q5 (a) What are the various steps for evaluation of tenders?
Tender evaluation involves checking eligibility of bidders, technical evaluation, comparison of quoted rates, checking arithmetic accuracy, assessing financial capability, and finally selecting the lowest responsive and responsible bidder.
Q6 (a) With the following data of activities of a project, develop a suitable network by CPM. Determine project completion time, critical path and total float.
Activities and duration (days):
A = 5
B (after A) = 6
C (after B) = 14
D (after B) = 8
E (after D) = 5
F (after C & E) = 9
G (after F) = 6
By drawing CPM network and performing forward and backward pass,
The critical path is A → B → C → F → G.
The project completion time is 40 days.
Activities on critical path have zero total float, while others have positive float.
Q7 (a) Write short notes on:
(i) Earnest Money Deposit
(ii) Security Money**
Earnest Money Deposit (EMD) is the amount submitted by the contractor with the tender to show seriousness. It is forfeited if the contractor withdraws the bid.
Security Money is deposited after award of contract to ensure proper execution of work. It is returned after successful completion of the project.
