Infrastructure Quantity Surveying & Estimation with AutoCAD

Describe the work inspection request (WIR) process, detailing contractor, consultant, and client roles, inspection against drawings and specifications, and how approvals drive payment.

Understand the delivery note's purpose and essential fields, such as supplier, project, date, and unique numbers, and see how inspectors verify delivery and integrate it with payment application.

Learn to read storm drainage drawings by interpreting legends, symbols, and color codes for manholes and pipes (RCP and GW), and understand plan and section details for quantity estimation.

Explore the underground manhole drawing details from top plan to section views, including diameter, wall thickness, PCC, and concrete construction, to estimate quantities for infrastructure works.

Explore how technical specifications complement drawings by detailing soil preparation, underground piping, manholes, concrete, and the strong drainage system, including execution, product handling, and testing.

Explore the civil engineering standard method of measurement (CSM) and how global length standards, coding, and item classification guide quantity preparation and project pricing.

Learn to read BOQ items with CESMM4 by decoding pipe works classifications, nominal diameters, depths, and reference codes, including exclusions and additional descriptions for BBC pipes.

Learn pipe measurement rules for infrastructure works, including centerline length, fittings, and profile guidance; measure inside manhole surfaces and account for excavation, backfill, reinforcement, and finishes.

Interpret the progress monitoring sheet and quantity sheet using drawing references, column meanings, and key formulas. Understand upstream and downstream, manhole, pipe details, and deductions to determine length.

Learn to use a progress monitoring sheet to track excavation, bedding, pipe laying, backfilling, testing, and commissioning with time and cost weightages and work inspection references.

Quantify pipe work for infrastructure projects using AutoCAD and Excel by entering data from drawings, identifying manhole references, calculating center-to-center pipe lengths, and updating progress with hatch marks.

Explore how to prepare and reference a work inspection request form, assign unique reference numbers, and report site inspections for excavation, piping, and related works.

Learn to perform take-off quantities for manholes by interpreting diameters of 1.2 m and 1.5 m, using reference lines to map wall thickness, and calculating excavation and concrete quantities.

Master pump station 3d drawing from concept to final cut, highlighting practical steps for understanding within quantity surveying for infrastructure works using cad and Excel.

Identify and locate pump station items from sectional drawings of the two rectangular live structures. Quantify components like PCC, retaining walls, foundations, slabs, manholes, waterproofing and roadworks for the BOQ.

Divide the pump station into main structure and shell, draw sections, set offsets, and compute areas and volumes to determine total excavation across deep and shallow portions.

Learn to quantify retaining walls for a pump station by reading plan drawings, defining long and short walls, calculating length, thickness, height, and total volume for deep and shallow structures.

Quantify the solid concrete slab for a pump station by isolating the slab from walls and defining its area. Compute gross and net volumes, deduct openings such as manhole covers.

Explore quantification of stainless steel ladder and manhole cover for a pump station, including 17 meter depth, site sizes, supplier quotations, unit rates, and installation costs.

Calculate vertical waterproofing for a pump station by assessing the front, left, right, and back wall areas. Exclude earth-connected zones and manhole openings, then sum to determine waterproofing area.
