1. Investment estimation (Party A);

2. Design budget (design institute);

3. Construction drawing budget (Party B);

4. Bidding and price control (Party A+bidding agency+Party B);

5. Completion settlement;

6. Final accounts of completion;

Second, the project cost process

1. Look at the drawings (paper version, electronic version -CAD or quick drawing tool or PDF);

2. Calculation (excel manual calculation, CAD tracing);

3. Team price (list item, fixed team price GCCP);

4. Charges (labor costs: according to the annual settlement price guidance price issued by the government or the price agreed by both parties of the construction and installation project (subject to this, material costs: refer to the local cost information in the bidding stage, and the quality and price are recognized in the settlement stage, and the mechanical costs are generally not adjusted);

5. Tabulation (GCCP according to the requirements of the tenderee or bidder);

Third, the cost structure.

1. Partial project cost (labor cost, material cost, material risk rate of 5%, machinery cost, machinery risk cost of 3%, management fee and profit, remember to calculate on the basis of collected labor cost);

2. Measures fee: total measures fee (safety and civilized construction measures fee, according to%), other measures fee (winter night rain has gone to the second construction site, according to%), major: professional engineering) and unit price measures fee;

3. Other projects (provisional amount, provisional valuation, general contracting service fee, daily work);

4. Expenses (five insurances, one gold and one pollution);

5. Tax (11%);

Four, municipal engineering cost content

1. General and measures project (entity part (earthwork (trench, foundation pit, general earthwork), demolition project, transportation of finished products and semi-finished products) and measures part (scaffolding project, formwork and supporting project, tool pile pulling, cofferdam island building, temporary bridge, drainage and precipitation, vertical transportation of structures, ventilation in holes and dynamic lighting track));

2. Road engineering (black asphalt concrete pavement and white cement concrete pavement) is different from highway engineering, and the cost of highway engineering is similar to water conservancy and land consolidation engineering): subgrade, base and surface;

3. Bridge and culvert works: bridge components such as pile foundation, bearing platform, pier, capping beam, bearing, plate beam, box girder, concrete pavement, anti-collision guardrail, bridge end transition slab, behind ear wall, expansion joint and drainage pipe; Circular culvert, square culvert, box culvert, etc. ;

4. Drainage works: pipeline foundation (gravel foundation, concrete foundation), pipeline laying, interface treatment, closed water test, pipeline backfilling, rainwater and sewage inspection wells, rainwater outlets and sewage outlets);

Five, CAD calculation commonly used shortcut keys and functions

1.OP (optional)-display-color-background color black;

2.LA(layer)- Show or hide, create a new layer and set the current layer;

3.CO (replication);

4.m (mobile);

5.BO (Boundary Creation)-Pick up internal points;

6.PL (polyline) -A (arc) -S (second point) -L (straight line) -C (closed);

7.CH (feature)—View perimeter and area;

8. Li (measuring circumference and area);

9.TR (pruning)

10.d (size style)/scale factor

Six, earthwork quantity

1. Trench (trench and wall foundation) (B≤7m, L & gt3B)

V Qing = aHL

V =(B+KH)HL, where B=a+2c(k look-up table of slope coefficient, c look-up table or 06MS20 1 municipal drainage atlas).

2. Foundation pit (manhole, rainwater outlet, abutment and column pit) (L ≤ 3B, S ≤ 150m2)

V Qing = abh

v =(a+2c+KH)(b+2c+KH)6+2c+KH)h+ 1/3k2h 3；

v = 1/6h(A b+ A 1b 1+(A+A 1)(b+ B 1))

3. General earthwork (subgrade excavation and filling, channel earthwork)

V Qing =V Ding =(A 1+A2)/2*L

Seven, the number of road projects

1. Subgrade shaping and rolling shall be calculated according to subbase area;

2. Lime-fly-ash subbase: According to the base area, the factory-mixed base mixture quota and the top composite soil solidification quota are generally taken, and the main materials are supplemented (volume = subbase area * thickness (generally 20cm)* loose paving coefficient (about 1.25) * loss coefficient1.02);

3. Lime-fly ash soil and lime-fly ash macadam are the same as above;

4. Primer coat, seal coat and adhesive coat: Primer coat and seal coat are calculated according to the area of top base; The adhesive layer is calculated according to the surface area;

5. Coarse, medium and fine grained asphalt concrete pavement: calculated by area, excluding inspection wells, deducting flat stone area;

Eight, the number of bridge engineering

1. Pile foundation: mechanical bored pile (pile diameter: 1200mm, pile top elevation:-1.6m, pile bottom elevation 0 # ~ 4 #:- 13. 15m, 5#, 6 #.

2. Process flow: (1) Prepare mud; (2) Bury steel liners; (3) Drill holes; (4) Lower steel cages; (5) Pour underwater concrete; (6) Chisel pile heads; (7) Excavators dig and install dump trucks to transport stone slag.

3. The mud preparation amount is about 1.3~3 times of the pore-forming volume, and V mud = 0.785 *1.2 2 * (1.55 * 20+14.40 * 8).

4. Length of steel sleeve: L steel = 1.5*28.

5. Hole formation: L hole =11.55 * 20+14.40 * 8.

6. Pouring concrete:

V irrigation = 0.785 *1.22 * (11.55+1) * 20+(14.40+1) * 8).

7. Chisel the pile head concrete, dig and transport the stone slag V chisel =V dig =V transport = 0.5 * 28 * 0.785 * 1.2 2.
