๐Ÿ‘‰Project Control Techniques for Successful Project Management

๐Ÿ’ซIn the world of project management, having the right control techniques can make all the difference between a project that meets goals and one that veers off track. Here are some of the top techniques to ensure projects stay on schedule, within budget, and aligned with quality standards:

1๏ธโƒฃ Earned Value Management (EVM): Evaluate project performance by comparing planned work vs. actual progress and costs.

2๏ธโƒฃ Critical Path Method (CPM): Identify the essential tasks impacting project timelines to prioritize resources effectively.

3๏ธโƒฃ Gantt Charts: Use visual timelines to track task progress and spot any delays.

4๏ธโƒฃ Work Breakdown Structure (WBS): Break down projects into manageable tasks for clear assignments and better cost estimation.

5๏ธโƒฃ Risk Management: Proactively identify and manage risks to mitigate issues before they impact the project.

6๏ธโƒฃ Change Control: Keep the project aligned by managing scope, schedule, and budget changes systematically.

7๏ธโƒฃ Cost Control: Monitor expenses and adjust to prevent budget overruns with variance analysis and forecasting.

8๏ธโƒฃ Quality Control: Regular testing, audits, and inspections to ensure deliverables meet defined standards.

9๏ธโƒฃ Resource Allocation & Leveling: Optimize resource usage to avoid overload and maintain efficiency.

๐Ÿ”Ÿ Milestone Tracking: Track key milestones to ensure significant project stages are completed on time.

Project control techniques are essential for staying on track and delivering value. By combining these methods, project managers can make informed adjustments and ensure project success!

๐Ÿ‘‰Self-compacting concrete

๐Ÿ’ซSelf-compacting concrete (SCC) is a specialized type of concrete that flows and spreads easily through formwork and around obstructions without the need for mechanical vibration. This is achieved through a careful balance of mix ingredients and the use of superplasticizers.

๐Ÿ—๏ธWhen to Use SCC

โœ”๏ธIn complex structures with dense reinforcement where conventional vibration would be difficult.
โœ”๏ธIn areas where noise reduction is important, such as urban locations.
โœ”๏ธ For elements with intricate shapes or surface textures that could be affected by vibration.
โœ”๏ธLarge construction projects where efficiency and speed are priorities.

๐Ÿ—๏ธAdvantages of SCC

โœ”๏ธImproved Quality and Finish: Provides a superior surface finish and better filling of forms.
โœ”๏ธReduced Labor and Noise: No need for vibration reduces labor costs and construction noise.
โœ”๏ธTime Efficiency: Faster placement reduces project timelines.
โœ”๏ธEnhanced Durability: Better compaction leads to improved strength and durability.
โœ”๏ธVersatility: Suitable for a variety of applications from precast structures to commercial builds.

๐Ÿ“œOverall, SCC enhances the construction process in terms of quality, efficiency, and sustainability.

๐Ÿ‘‰Subject : Foundations

๐ŸทFoundations can be shallow or deep, depending on the depth of the soil in which they are built.

๐Ÿ’ซWhat Is Shallow Foundations ??

โญ๏ธANSWER

โบShallow foundations are typically used for low-rise buildings or structures that are wider than they are tall.

๐Ÿ’ซWhat Is Deep foundation??

โญ๏ธANSWER

โบDeep foundations are used for structures that require more than 1.5 meters of depth to transfer their load.

๐ŸทParties may contemplate minor variation in quantity from contract estimate, especially if engineering documents aren't issued โ€œApproved for Construction (AFC)โ€

๐Ÿ’ซEven when AFC drawing issued prior to establishing contract price, change may occur, cause deviation from approved design & significantly increase or decrease required quantity to be installed & contractorโ€™s cost

โบUnder unit price contract contractor typically buy material, add overhead, profit markup & agree to perform work for this unit price

โ–ถ๏ธIf ownerโ€™s estimated quantity is higher than actual quantity, contractor may claim for unrecovered overhead cost & profit

Owner realize cost saving as result of value engineering, design change, reduce quantity, then request credit from contractor

Contractor might not pass on full saving achieved from ownerโ€™s change, potentially cause dispute with owner who expect larger credit

Contractor take risk with unit price contract tactically apply its overhead & profit % in unbalanced manner to items for which it expects large quantity increases as design matures, thus receiving additional profit layer

Such practice may backfire if โ€œover-pricedโ€ items quantities don't increase or decrease as result of value engineering, thus reduce contractorโ€™s overhead & profit recovery

Equitably assign risk of increase or decrease in estimated quantity result from information or conditions not reasonably apparent to parties when they enter into contract to prevent harmful losses

Contract include provision, after given variation % (e.g 15-25 %), there can be adjustment to unit price

Technical specs & drawings describe what work is payable

โ€œDiffering Site Conditionsโ€ clause override โ€œVEQโ€ clause when:
1)Actual quantities clearly exceed contemplation of parties; &

2)Cost of doing extra work greatly differs from stated unit-price because of factors not foreseen by either party

โ€œDiffering Site Conditionsโ€ clause may also prevail over use of โ€œVEQโ€ clause:
1)Ownerโ€™s estimate found to be prepared negligently; &

2)Owner fail to disclose โ€œsuperior knowledgeโ€ result quantity overrun

Contractor must maintain record of all cost associated with change or extra work

Advantage of recovery under โ€œDiffering Site Conditionsโ€ to contractor isn't limited to unit price but can recover actual cost plus reasonable overhead & profit

The only notice requirement imposed by VEQ clause is related to requests for (EOT)

๐Ÿ‘‰TYPES OF DRAWINGS USED IN BUILDING CONSTRUCTION

๐ŸšงDrawings are the most important things we need to start any construction project.

๐ŸทThere are different types of drawings for different purposes.

๐Ÿ“œIn this article, we will discuss different types of construction drawings (also known as working drawing)

โบConstruction drawings provide detail measurements and clear section of every building parts.

โบAfter reviewing, the drawings are justified and modified and finally approved for construction.

๐Ÿ’ซThe different types of construction drawings are listed below.

1) ARCHITECTURAL DRAWING

โบThis type of drawing provides complete view of a building. It demonstrates the location of the building and all building parts where they will be placed.

โบThere are different types of architectural drawings
with different names such as plan, elevation, section
etc.

2) STRUCTURAL DRAWING

โ–ถ๏ธAs the name suggests, this type of drawing provides information about structure, like strength of different structural elements, structural materials, grade, size and placement of reinforcement etc.

3) ELECTRICAL DRAWING

โบThis type of drawings provide the details and location of electrical wiring, fixtures, substation etc.

โ–ถ๏ธThe electrical load calculation is also given in the drawing.

4) PLUMBING AND SANITARY DRAWINGS

โบThese drawings give the location of sanitary, piping
for water supply system, fixture, and the process to
connect every fixture etc.
