the entire project and documenting all the jobs that must be completed. It helps allow for budgeting and access to materials that are required Project Management Planning
2. : The expenses of each project must
be efficiently managed throughout the process to ensure
for adjustments for unexpected issues or difficulties Cost Management
3. : A construction manager must
make sure that the contractors employed for the project are completing it to a high-quality standard. Monitoring the process, costs and quality is all highly critical Quality Management
4. : Extensive contracts with the
client are all part of the project construction process.
The contract provisions must be being met to ensure that all parties involved are satisfied Contract Administration
5. : As a construction site can be a
dangerous place with many safety hazards, the building manager must ensure that correct processes are in place to make sure there are no accidents.
The construction manager needs to ensure that the work meets all the legal requirements and Building Regulations

.
👉Who They Manage and How
Construction managers will be responsible for managing individuals in various roles appropriate for the project. Before
any of the actual building work can take place, the plans
must be discussed with the architect, surveyors and buyers.
These types of managers will be required to hire the relevant
staff needed to complete the project to the client’s standard. It is important that all these members of staff are
managed effectively so that the plans for the project can be
fully understood and developed. The construction manager
will need to hire and organise various contractors and
suppliers, and coordinate the subcontractor’s activities.

👉The first goal of accurate estimating and bidding system.

🚧This is to insure you know and track job labor, equipment, material and subcontractor costs.

🤔Ask yourself these questions as you think about preparing your next bid:

• 📌Do you know and track job costs?

• 📌Do you recap final costs versus the estimate?

• 📌Do your field timecards reflect the real costs per work item?

• 📌Does your accounting system give timely job cost reports?

• 📌Will your estimate produce accurate costs?

• 📌Do you keep track of labor costs?

• 📌Do you have a cost history library?

• 📌Do you feel confident in your costs?

• 📌Are your general conditions costs accurate?

• 📌Is your labor burden rate correct?

• 📌Is your crew bidding rate accurate?

• 📌Are your equipment rates accurate?

• 📌Is your overhead markup sufficient to recover your overhead?

• 📌Is your profit markup enough to give you a proper return?

What's your estimator's No. 1 priority? When I speak at conferences or conventions, I get many responses to this question. They include the following:

• 📌Bid lots of jobs

• 📌Get lots of work

• 📌Maximize sub-bid coverage

• 📌Be competitive

• 📌Know what things cost

• 📌Make a profit

The #top_priority for my #estimator is to arrive at #accurate job costs.

I don't want our bid to be an estimate of what a job might cost, plus or minus 10 percent.

Estimating accuracy is a key to long-term construction business success.

The only variable on any bid should be the #profit mark-up. Excellent and experienced estimators know what things cost.

In my opinion, their estimating goal must be to prepare bid estimates within 1 or 2 percent of the final actual cost on every job. Good estimators continually compare their #past_bids to the final job cost results to see how accurate they were.

Then they make adjustments accordingly for their next bids. They are in constant contact with the field superintendents and foremen to review how they arrive at estimated costs.

✅They continually review labor, material, equipment, subcontractor and supplier costs to insure they know every possibility for differences in the jobs they bid.

👉Accurate Estimating Rules

1. 📌Every estimate covers your job costs.✨💫

🚧Your estimating goal is to calculate the ACCURATE final cost of building each project you bid.

▶️Estimates should not include any "fat," "fudge factor" or "slop" to cover unknowns. A perfect estimate equals your actual cost of doing the work.

⏺Can you cut your costs? No, unless your crew leaves something out or gets creative during the installation process.

2. 📌Your estimate is the total cost.

🚧Estimating is arriving at the total job cost. To arrive at accurate costs, the estimator is responsible for knowing what things cost. They must review final job costs and update their cost history library on an ongoing basis.

3. Your bid is the total contract amount.

🚧A bid is the sum of accurate estimated job costs, plus your overhead recovery markup, plus your profit markup to hit your company goals. You job costs shouldn't vary from the estimate.

▶️Your overhead is the amount required to recover the cost of doing business. Can you cut your costs or overhead? Both job and overhead costs can't be cut when you are preparing bids as these are fixed amounts.

⏺The only bid variable is profit. Profit is the reward for taking business risks and should be adjusted based on project risks.

4. 📌Contracts are opportunities!

🚧When you are awarded a job you have an opportunity to get paid for job costs to cover labor, equipment, material and subcontractors.

▶️Then you have an additional opportunity to make some money, only and after you recover your overhead. Your overhead is a set amount determined by your fixed cost of doing business. Your overhead includes all of your general and administrative costs and goes on with or without any jobs under construction. Each job must pay its pro-rata share of your annual overhead budget.

▶️Many times I listen to construction business owners lament over how they can't get enough markup to make a profit, or they complain they bid work and it comes in costing more than they figured, or they never have enough money to pay themselves a good salary. The problem is simple. Basic business math must be understood.

❗️Volume - Job Cost - Overhead = Profit

▶️You can cover your job costs on every job, but not have enough left over to recover your overhead or make a profit. This usually happens to contractors who don't understand business fundamentals. You don't make a profit until all of your annual job costs are paid for plus you pay back all of your overhead costs for the year.

▶️Most companies don't cover their overhead costs until October or November and don't make a profit until December. Just because you have money in the bank doesn't mean you are profitable.

▶️When you increase overhead by hiring an estimator or bookkeeper, your choices are simple: raise markup or increase sales volume.

✅If your volume or markup decreases in a softening market, your only choice is to cut overhead or increase sales. When job costs increase, you're in trouble as your only choice is more sales. Most owners mistakenly focus on cutting costs instead of increasing revenue when things go bad.

👉Accurate Estimating

1. 📌Accurate Time Cards-Excellent estimators know accurate estimating starts with accurate information from the crews who actually do the work.

#Step_one is to insist your timecard is divided into the cost codes you want to estimate with. Then, it's the #estimator's responsibility to insure field workers are filling out timecards correctly.

2. 📌Accurate #Labor Burden Rate-Do you know how your labor burden rate is calculated? Is it accurate or an approximation of what your #accounting department thinks it should be? An accurate labor burden rate is essential for accurate estimating.

If your rate is padded, you are too expensive, and if it's not complete you'll bid too cheap. Review it for accuracy and include taxes, workers' compensation, medical, liability insurance, vacation, union dues, safety training, small tools, overtime and down-time.

3. 📌Accurate #Crew Bid Rate-Excellent estimators use different crew rates to bid different projects based on what the job needs.

A crew on a difficult job needs more experienced people, while a larger simple project can use less trained crew members. Figure different crew sizes and make-ups to determine your accurate man-hour crew bid rate.  

I like to calculate #bid rates for two-, three-, five-, ten-, and twenty-men crews. You will find your bid rate varies considerably for different crews.

4. 📌Accurate #Equipment Rates-Excellent estimators know what equipment really costs. Calculate the cost for each piece of equipment your company uses.

✅Total the purchase price, interest, maintenance, gas and insurance over the life of the equipment. Divide this total cost by the expected number of billable hours to arrive at you accurate cost per hour.

5. 📌Accurate #General #Conditions-Most estimators either guess at the actual costs of job start-up, managing, supervising, temporary facilities and closing out projects, or they use a percentage to figure general conditions.

And, the unit prices they use are often #outdated and inaccurate. Most of the time general conditions can vary from month to month.

#Accurate estimating must include a review of what your #general_conditions really cost and then a budget based on input from the field.

6. 📌Accurate #Overhead-Your company overhead is a fixed (not a percentage) amount. Divide your total #projected_annual overhead by your total projected annual job costs (not sales volume).

This percentage will equal the actual overhead recovery markup to use.

Example: 800,000 Birr projected #annual_overhead divided by 5,000,000 Birr projected annual job costs equals 16 percent #markup for overhead recovery.

Don't get trapped into thinking you can use an industry average such as 10 percent or 15 percent to cover your overhead costs.

7. 📌Accurate #Profit MarkUp-Profit markup is 👉🏾not determined by what you can get.

It is a fixed amount of what you want. ❗️To determine the profit markup required to hit your goal, divide your total annual projected costs by your annual profit goal to determine markup.

🖍Example: 400,000 Birr annual profit goal divided by 5 million Birr projected annual job costs equals 8 percent markup to hit your profit goal.

If you can't achieve 8 percent profit markup in your market, your only solution is to adjust your volume up and your markup down until you hit your 400,000 Birr profit target.

✅Want to make lots of money? Make your bid more than a "guestimate." Make each estimate an exact prediction of what it will take to build every project.

Install accurate estimating systems and controls and watch your #bottom-line results improve significantly.

Solution:

Of course diameter of solid particle is not given as our member said in comment section

Let’s use Kozeny-Carman formula,

k = e³ /(1+e)

▶️ k1/ k2 = 0.012/k2 in this case
k1 = 0.012 and k2 is unknown

Let’s use the formula

K1 = e1³ /(1+e1) እሺ
K2 = e2³ / (1+e2)

k1 = (0.57)³ / (1+ 0.57) = 0.3249

K2 = (0.72)³ / (1+0.72) = 0.21004651

= 0.3249/0.21004651 = 0.544

So k2 = 0.012/0.544= 0.02cm/s


Notice that since k, = 0.012 cm/s the permeability has almost doubled. A 26% increase
of the voids ratio has effected a doubling the permeability.
